5.2 Connecting Computers Wirelessly over WLAN

Using WLAN radio technology you can connect multiple com- puters with the FRITZ!Box wirelessly. Please note the following before establishing a wireless con- nection between the computer and the FRITZ!Box:

• WLAN device A computer to be connected to the FRITZ!Box via WLAN must be equipped with a WLAN device for it to support WLAN. A WLAN device can be an external WLAN adap- ter—like a USB stick, for example—or a device integrated in the computer. Many modern computers and note- books come with a WLAN device integrated.

• WLAN security settings In the FRITZ!Box, WLAN security settings are enabled up- on delivery. Before a computer can establish a wireless connection to the FRITZ!Box, the WLAN security settings of the FRITZ!Box must be transferred to the WLAN device. For this procedure the FRITZ!Box supports the two auto- matic methods AVM Stick & Surf and WPS (Wi-Fi Protect- ed Setup). The security settings can also be transferred manually. For more information on WLAN, see the section FRITZ!Box as a WLAN Base Station from page 55.FRITZ!Box 3370 20 Connecting Computers Wirelessly over WLAN Establishing a WLAN Connection with AVM Stick & Surf If you use a FRITZ!WLAN USB Stick from AVM as the WLAN de- vice, you can use AVM Stick & Surf to establish a secure WLAN connection quickly and conveniently.

1. Switch on your computer.

2. Insert your FRITZ!WLAN USB Stick into one of the USB

ports on the FRITZ!Box. The WLAN security settings are transmitted to the FRITZ!WLAN USB Stick. The “Info” LED on the FRITZ!Box begins flashing quickly. As soon as the “Info” LED stops flashing, transmission of the settings has been concluded.

of the computer. The security settings will be adopted and the WLAN connec- tion between the FRITZ!Box and the FRITZ!WLAN USB Stick will be established. As soon as the WLAN connection has been established the computer is connected to the FRITZ!Box. Establishing a WLAN Connection Using WPS The FRITZ!Box supports WPS (Wi-Fi Protected Setup). WLAN devices that also support WPS can be connected with your FRITZ!Box securely using this method. All of the necessary WLAN security settings are transferred in the process. There are two kinds of WPS: the push-button method and the PIN method. See the AVM FRITZ!WLAN USB Stick manual for details.Connecting Computers Wirelessly over WLAN FRITZ!Box 3370 21 WPS with the Push-button Method The push-button method (WPS PBC) can be used if your WLAN device is equipped with a WPS button, or if WPS can be en- abled via the control software of the WLAN device.

1. Press the “WLAN” button on the FRITZ!Box until the

“WLAN” LED begins flashing.

2. When the “WLAN” flashes, start WPS on the WLAN de-

vice. You have 2 minutes for this task. How to start WPS depends on the WLAN device. Either press a button on the WLAN device, or start WPS in the control software of the WLAN device. The connection between the FRITZ!Box and the computer is established automatically. The computer is now connected with the FRITZ!Box. WPS with the PIN Method If your WLAN device supports WPS, but does not have a but- ton to start the push method nor any possibility to enable it in its control software, use the PIN method to establish the WLAN connection. You can choose between two methods:

6. The PIN will be displayed. Enter this PIN in the control

software of the WLAN device.

7. Click “Start WPS”.

The “WLAN” LED on the FRITZ!Box flashes slowly, indicating that the WPS procedure has begun. Now a secure WLAN con- nection is being established between the FRITZ!Box and the WLAN device. The WLAN Device Specifies the PIN

5. Select the option “PIN method (WPS-PIN), the WLAN de-

vice specifies the PIN”.

6. Now start the control software of the WLAN device. The

program outputs a PIN for establishing a connection.

7. Enter this PIN in the FRITZ!Box user interface.

8. Click “Start WPS”.

The “WLAN” LED on the FRITZ!Box flashes slowly, indicating that the WPS procedure has begun. Now a secure WLAN con- nection is being established between the FRITZ!Box and the WLAN device.Connecting Computers Wirelessly over WLAN FRITZ!Box 3370 23 Transferring the WLAN Security Settings Manually The WLAN security settings for WLAN devices can also be transferred manually. Manual transfer is unavoidable if a WLAN device does not support any methods for transferring the security settings automatically. For manual transfer the WLAN security settings have to be en- tered in the WLAN software. WLAN devices are generally delivered with their own WLAN software, which is installed in the computer along with the WLAN device. By now many operating systems have WLAN software included. Integrated WLAN devices sometimes use the operating system’s WLAN software. Installing a WLAN Device If you need to use a separate WLAN device because you do not have one integrated, then install the WLAN device in the computer along with the corresponding WLAN software. Please take note of the instructions in the documentation of the device. Transferring WLAN Security Settings The values for WLAN security preconfigured in the FRITZ!Box have to be transferred to the WLAN device.

1. Start the WLAN software.

2. The following table presents the values that are possible

for the connection between the FRITZ!Box and the WLAN device. Enter in the WLAN software the values set in the FRITZ!Box. If you changed the preconfigured values in the FRITZ!Box, then enter these changed values in the WLAN software. The values preset in the FRITZ!Box are printed on the sticker attached to the bottom of the housing. If you would like to establish a WLAN connection using these values, then your WLAN device must support the preset encryption method. If this is not the case, first change the settings in the FRITZ!Box. To do this, connect your computer and the FRITZ!Box using a network cable.FRITZ!Box 3370 24 Connecting Computers Wirelessly over WLAN

3. Confirm your entries using the relevant button in the us-

er interface (for instance, “OK” or “Connect”). Now your WLAN device and the FRITZ!Box are connected with each other wirelessly. If the WLAN Device Does Not Support WPA If your WLAN device does not support WPA encryption, you must convert the encryption set in the FRITZ!Box to WEP. For this you must change the WLAN settings in the FRITZ!Box.

1. Connect the FRITZ!Box and the computer using the net-

work cable (yellow) (see the section Connecting Compu- ters to the LAN Port on page 17).

2. Open the FRITZ!Box user interface (see the section

and enter a network key.

This chapter explains the possibilities offered by using the FRITZ!Box as an Internet router and how to take advantage of them.

10.1 Child Protection: Restricting Internet Access

The child protection feature allows you to define access rules to the Internet for individual computers or Windows users. These access rules may include restrictions of Internet access time, filter lists and a list with blocked network applications.

• Restrict Internet access time: Using the time restriction you can restrict the amount of time the user can surf the web. You can define on which days of the week, at what times of day, and for how long a computer or Windows user is allowed to use the Internet connection.

• Block or permit web sites: you can use filter lists to de- fine which Internet pages are allowed to be accessed and to which access is blocked. For instance, you can block all Internet pages the government has defined as offensive or harmful to minors. You can create both filter lists, the whitelist and the blacklist. A whitelist contains all Internet pages to which access is allowed. A blacklist contains all Internet pages to which access is blocked.

• Block network applications: You can list network appli- cations for which Internet access should be blocked. For instance, you can block Internet access for file-sharing software. Child protection can be enabled for each computer individu- ally, regardless of the computer’s operating system. You can also enable child protection individually for all Win- dows users in all Windows operating systems (Windows 7, Windows Vista and Windows XP). This option is useful if a computer is used by multiple users.FRITZ!Box 3370 42 Port Forwarding: Making Computers Accessible from the Internet The child protection feature is available only if you have set up the Internet connection in the FRITZ!Box and established an Internet connection. Child protection is not available if you have configured the FRITZ!Box as an IP client. In this case, use the corresponding functions of the router whose Internet con- nection is being shared. Setting Up Child Protection in the FRITZ!Box

3. Set up child protection. See the Online Help available in

the FRITZ!Box user interface for more information.

10.2 Port Forwarding: Making Computers Accessible from the Internet

With default settings in the FRITZ!Box, programs on your com- puter and LAN cannot be accessed from the Internet. For ap- plications like online games and file sharing software or serv- er services like HTTP, FTP, VPN, terminal and remote access servers you have to make your computer accessible for other Internet users. Port Forwarding Using port forwarding, you allow incoming connections from the Internet. By releasing certain ports for incoming connec- tions, you grant controlled access to your computers in your network to other Internet users. Ports serve to assign incom- ing data packets to the various applications when all applica- tions can be accessed at one IP address only. The following port forwarding methods are possible in the FRITZ!Box:Port Forwarding: Making Computers Accessible from the Internet FRITZ!Box 3370 43 PING IPv4: The FRITZ!Box responds to ping inquiries from the Internet addressed to the IPv4 address of the FRITZ!Box. IPv6: The FRITZ!Box responds to ping inquiries from the Internet addressed to the IPv6 address of the FRITZ!Box. Additionally, you can set up PING6 port forwarding rules for each computer in the home network since each computer has its own globally valid IPv6 address. TCP UDP IPv4: Within IPv4 networks you can open the FRITZ!Box firewall for the protocols TCP and UDP when en- tering the port range. One port can be opened for exactly one computer. IPv6: Within IPv6 networks you can open the FRITZ!Box firewall for the protocols TCP and UDP when en- tering the port range. One port can be opened for each computer in the network. ESP GRE IPv4: Within IPv4 networks you can open the firewall for the two protocols ESP and GRE which do not use ports. Exposed Host (Open firewall completely) IPv4: Within IPv4 networks you can open the firewall for one computer completely. This computer is then no longer protected by the FRITZ!Box fire- wall. If individual ports are already open for other computers, then data packets for these ports are not forwarded to the exposed host but to the oth- er computer instead. IPv6: Within IPv6 networks you can open the firewall for each computer completely. These computers are then no longer protected by the FRITZ!Box firewall.FRITZ!Box 3370 44 Port Forwarding: Making Computers Accessible from the Internet Setting Up Port Forwarding in the FRITZ!Box

• IPv4: Port forwarding for IPv4 is set up in the “Internet / Permit Access” menu, on the “Port Forwarding” page.

• IPv6: Enable the advanced view. Port forwarding for IPv6 is also set up in the “Internet / Permit Access” menu, on the “IPv6” page. Determining the IPv4 Address for Accessing the FRITZ!Box If you have enabled ports for forwarding in the FRITZ!Box, oth- er Internet users can access your computers at the IP address assigned to your FRITZ!Box by the Internet service provider. This is a public IPv4 address. Here is how to determine the public IPv4 address of the FRITZ!Box:

1. Open any Internet page in order to establish an Internet

vanced view in the user interface.

3. The FRITZ!Box’s public IPv4 address is displayed on the

“Overview” page in the “Connections” area. Every time the Internet connection is interrupted the Internet service provider re-assigns the IP address. The IP address may change in the process. Therefore it is a good idea to use MyFRITZ! or dynamic DNS so that the IP address can always be reached under the same name. For more information about MyFRITZ!, see the section MyFRITZ!: Global Access to the FRITZ!Box on page 38. For more information about dy- namic DNS, see the section Dynamic DNS: Name Instead of IP Address on page 45.Dynamic DNS: Name Instead of IP Address FRITZ!Box 3370 45

10.3 Dynamic DNS: Name Instead of IP Address

Dynamic DNS is an Internet service that makes it possible for the FRITZ!Box to remain accessible from the Internet at all times under a fixed name, even though the public IP address changes. Dynamic DNS can be used as an alternative to MyFRITZ!. Both services can be used in parallel. You must register with a dynamic DNS provider to use this service. When you register, you agree on the fixed name (do- main name) at which your FRITZ!Box should be accessible from the Internet. You also define a user name and password. Every time the IP address changes, the FRITZ!Box transmits the new IP address to the dynamic DNS provider in the form of an update request. Then the domain name is assigned to the current IP address by the dynamic DNS provider. Setting Up Dynamic DNS in the FRITZ!Box

1. Open the FRITZ!Box user interface (see page 26).

2. Enable the advanced view.

3. Select the “Internet / Permit Access” menu.

4. Select the “Dynamic DNS” page and set up dynamic

DNS. Consult the Online Help available in the FRITZ!Box user interface for more information.

10.4 Remote Access over HTTPS

With this function it is possible to access the user interface of the FRITZ!Box from another location. This allows you to con- figure settings in the FRITZ!Box or perform a FRITZ!OS update using a computer that is not in your own network (LAN or WLAN). Setting Up Remote Access over HTTPS in the FRITZ!Box

Prioritization: Right of Way for Internet Access

4. Select the “Remote Access” page and set up dynamic

DNS. For more information, see the Online Help.

10.5 Prioritization: Right of Way for Internet Access

Prioritization is a function you can use to specify that network applications and network devices be treated with higher or lower priority when they access the Internet connection. For example, you may wish to ensure that applications like IPTV and video on demand are always treated with higher priority than other applications. You can also specify that file-sharing applications like eMule and BitTorrent always have to wait be- hind online games. Categories for Prioritization There are three categories for prioritization: “Real-time appli- cations”, “Prioritized applications” and “Background appli- cations”. The categories are explained below. Network applications and network devices are assigned to the categories using rules. Real-time Applications This category is suitable for applications with high demands on transmission speed and reaction times (for example, IPTV or video on demand).

• Network applications of this category always have priori- ty over other applications accessing the Internet at the same time.

• When the Internet connection is working at full capacity, the network packets of the applications of this category will always be sent first. In this case data from network applications assigned to other categories, like “Priori- tized applications”, will be transmitted later.

• If multiple network applications are assigned to this cat- egory, then they must share the available capacity.

• Whenever Internet telephony is included in this catego- ry, this application always has the highest priority, even over other real-time applications.Prioritization: Right of Way for Internet Access FRITZ!Box 3370 47 Prioritized Applications This category is suitable for applications that require a fast re- action time (for example, company access, terminal applica- tions, games).

• For network applications prioritized in this category, 90% of the FRITZ!Box’s upload bandwidth is available, as long as no application from the “Real-time applica- tions” category requires bandwidth. The remaining 10% of the upload bandwidth is available for applications that are prioritized in lower categories or not prioritized at all.

• If multiple network applications are assigned to the “Pri- oritized applications” category, then they must share the available capacity. Background Applications This category is suitable for applications that do not require any high transmission speed and which are not time-critical (for example, peer-to-peer services or automatic updates).

• Network applications assigned to this category are al- ways treated with the lowest priority when the Internet connection is working at full capacity. So whenever an application from a different category or a non-prioritized application requires the entire bandwidth, all back- ground applications must wait until bandwidth capacity becomes available again.

• If no other network applications are active, then the background applications receive the entire bandwidth. Prioritization Method in the FRITZ!Box The following algorithm is used in the FRITZ!Box to send data packets according to their prioritization:

• Change in the order in which packets are sent to the In- ternet (upstream direction) The order of the packets the FRITZ!Box receives from the Internet (downstream direction) cannot be changed.FRITZ!Box 3370 48 VPN: Remote Access to the Home Network

• Discard low-priority packets in order to ensure the trans- mission of higher-priority packets. This algorithm is used whenever more packets are supposed to be sent to the Internet than the upstream transmission rate of the Internet connection allows.

• As long as no packets are being sent from higher-priority applications, the full transmission rate of the Internet connection is available for low-priority packets. Setting Up Prioritization in the FRITZ!Box

1. Enable the advanced view.

2. Prioritization is set up in the “Internet / Filters / Prioriti-

10.6 VPN: Remote Access to the Home Network

Via VPN (see glossary) a secure remote access to the network of the FRITZ!Box can be established. The VPN solution for the FRITZ!Box features the following:

• The VPN solution for the FRITZ!Box is based on the IPSec standard.

• Computer-LAN coupling and LAN-LAN coupling: VPN con- nections can be set up for individual remote computers or even for remote networks.

• A maximum of eight simultaneous active VPN connec- tions is supported.

• The configuration files for the VPN connections are creat- ed using a separate program. The program is provided free of charge and can be downloaded from the AVM web site.

• A free VPN client for individual computers can also be downloaded from the AVM web site. The AVM web site offers a Service Portal which presents com- prehensive information on VPN in general and in connection with the FRITZ!Box. Visit this portal to obtain more detailed in- formation. www.avm.de/en/vpnVPN: Remote Access to the Home Network FRITZ!Box 3370 49 Setting Up VPN in the FRITZ!Box

1. Open the FRITZ!Box user interface.

2. Enable the advanced view.

See the Online Help of the FRITZ!Box to set up VPN. Supplementary Software for VPN All of the information required for a VPN is saved in a configu- ration file. The terminals involved in any VPN must receive this file. Individual computers that are networked over a VPN require a VPN client.

• “Configure FRITZ!Box VPN Connection” Wizard AVM provides the “Configure FRITZ!Box VPN” software for creating configuration files. This program is a Wizard that takes you step by step through the VPN configura- tion. All of the necessary VPN settings, like the encryp- tion method and access rules, are set automatically. The resulting configuration files must be imported to the re- spective terminals of the VPN tunnel. At the terminal with the FRITZ!Box the configuration file is then imported to the FRITZ!Box. The VPN parameters in these files can be adjusted manually to connect to products by other manufacturers.

• The “FRITZ!VPN” VPN Client AVM offers the “FRITZ!VPN” software as a VPN client. Both the Wizard and the client can be downloaded free of charge from the VPN Service Portal on the AVM web site: www.avm.de/en/vpnFRITZ!Box 3370 50 DNS Server: Freely Selectable

10.7 DNS Server: Freely Selectable

DNS servers are preset in the FRITZ!Box for IPv4 and IPv6. These are the DNS servers assigned by the Internet service provider. For both IPv4 and IPv6, the preset DNS server can be replaced by a free DNS server. Free DNS servers include, for instance, OpenDNS and Google DNS. Here is how to change the DNS server entry:

1. Open the FRITZ!Box user interface.

2. Enable the advanced view.

4. Change the settings for the DNS servers.

10.8 DNSSEC: Security for DNS Queries

DNSSEC is short for Domain Name System Security Exten- sions. As the name says, this is an extension of DNS, the do- main name system. DNSSEC ensures that both the DNS server and the informa- tion returned by the DNS server are authentic, or genuine. Security with DNSSEC When a home user surfs the web, she or he sends queries to the Internet by entering URLs in the address line of the brows- er. A URL is the name of a web site that is easy to remember, such as www.avm.de/en . Every query is sent to the DNS serv- er first. The DNS server resolves the URL into the correspond- ing IP address. There is one unambiguous IP address for ev- ery URL. The “DNSv6” page is displayed only if you enabled IPv6 support for the FRITZ!Box on the “IPv6” page.IPv6: The New Internet Protocol FRITZ!Box 3370 51 The home user relies on the authenticity of the IP address re- turned by the DNS server. Authentic means that the response is the IP address of the desired web site, and not a faked IP address that leads to a fake web site. DNSSEC can ensure that the returned addresses are authentic. Support with the FRITZ!Box The FRITZ!Box supports DNSSEC queries over UDP. The FRITZ!Box has a DNS proxy. The computers in the home network use the FRITZ!Box as a DNS server. The FRITZ!Box for- wards DNSSEC queries from the home network to the Inter- net. The FRITZ!Box forwards DNSSEC responses from the In- ternet to the home network. The DNSSEC information must be validated on the computer in the home network. For this DNSSEC must be supported in the operating system.

10.9 IPv6: The New Internet Protocol

IPv6 stands for Internet protocol version 6 and is the succes- sor to IPv4. The FRITZ!Box supports the new IPv6 web protocol and can establish IPv6 connections:

• IPv6 support can be switched on in the FRITZ!Box user interface.

• For simultaneous use of IPv6 and IPv4, the FRITZ!Box supports dual-stack and dual-stack lite. This means that the FRITZ!Box can communicate with both IPv4 and IPv6 domains in the Internet.

• access to the user interface with http or https over IPv6

• The DNS resolver of the FRITZ!Box supports queries for IPv6 addresses (AAAA records) and can query the up- stream DNS resolver of the Internet service pInternet ser- vice providerrovider over IPv6.

• The globally valid prefix is distributed via router adver- tisement.

• For guest access to the WLAN, the home network and WLAN guests are separated by IPv6 subnetworks.

• completely closed firewall to protect against unwanted data from the Internet (Stateful Inspection Firewall)

• remote access via https

• IPv6 is not installed and enabled in standard Windows XP. You must install and enable IPv6 in order to use it. The IPv6 installation requires Service Pack 2 for Windows XP.

• IPv6 has been available in the Mac OS X operating sys- tems since Mac OS 10. 10.10Mobile Network: Replace Faulty DSL Internet access over the mobile telephone network can be set up so that the mobile telephone connection is established automatically whenever the DSL connection fails. This guar- antees Internet access even when the DSL connection is missing. A USB modem for mobile Internet access (UMTS/HSPA) and a SIM card from a mobile communications provider are required for this. The FRITZ!Box supports UMTS/HSPA modems from various manufacturers. Here is how to set up the mobile telephone connection as a substitute upon DSL failure:

In the “Internet” menu, the sub-menu “Mobile Tele- phone Network” is displayed.

3. Select the setting “Automatically enable the mobile con-

nection when the DSL connection is disrupted”. The “Mobile Telephone Network” menu is not available until the UMTS/HSPA modem has been connected to the USB port of the FRITZ!Box.FRITZ!Box 3370 54 Mobile Network: Replace Faulty DSL

4. Configure the settings for your Internet connection over

the mobile communications network. For more informa- tion, see the Online Help of the FRITZ!Box. Access to the Internet is now guaranteed, even when the DSL connection fails. As soon as the DSL connection is stable and available for at least 30 minutes, the connection will be switched back to the DSL connection.FRITZ!Box as a WLAN Base Station FRITZ!Box 3370 55 11 FRITZ!Box as a WLAN Base Station The FRITZ!Box is a WLAN base station for WLAN devices like notebooks, tablets or smartphones. The FRITZ!Box can establish WLAN connections compliant with the fast WLAN N standard in two different frequency bands at the same time. The FRITZ!Box is preconfigured with an encryp- tion method from today’s safest method WPA2. This encryption method is supported by most of the latest WLAN devices. The FRITZ!Box sup- ports wireless LAN convenience functions like guest access, night ser- vice and WPS Quick Connection.

11.1 Connecting WLAN Devices Securely with the FRITZ!Box

In a WLAN radio network security is of the utmost importance. This is why WLAN connections between the FRITZ!Box and your wireless devices are encrypted. For encryption the FRITZ!Box and your wireless devices must use the same en- cryption method. The FRITZ!Box is preconfigured with an en- cryption method that combines today’s safest methods WPA and WPA2. These encryption methods are supported by most of the latest wireless devices. If you would like to use wireless devices that do not support WPA2 or WPA, you can switch encryption in the FRITZ!Box to the older, less secure WEP method. You can also establish non-encrypted wireless LAN connections. However, if at all possible we recommend always establishing WPA2 wireless LAN connections. WLAN devices can be connected with the FRITZ!Box automati- cally or manually. A particularly simple and secure automatic method is WPS, with which a WLAN connection can be estab- lished at the touch of a button. For manual WLAN connections with the FRITZ!Box use the WLAN software of your WLAN de- vice or the WLAN program on your computer. Connecting WLAN Devices Automatically (WPS) WLAN devices that support the fast connection method WPS can be connected with the FRITZ!Box automatically.

1. Start the WPS function of your WLAN device. Consult the

documentation of the WLAN device to find out how to start WPS.FRITZ!Box 3370 56 Connecting WLAN Devices Securely with the FRITZ!Box

2. Press the WLAN button on the FRITZ!Box until the

“WLAN” LED begins flashing. You have 2 minutes for this task.

3. Your WLAN device and the FRITZ!Box now establish a se-

cure WLAN connection automatically. The FRITZ!Box “WLAN” LED stops flashing and remains on. With this, the WLAN connection is established. Your WLAN de- vice is integrated into your home network and can use the In- ternet connection of the FRITZ!Box. Connecting WLAN Devices Manually You can connect WLAN devices with the FRITZ!Box manually. WLAN devices like notebooks, tablets and smartphones use the WLAN software of their own operating system for this con- nection. A WLAN adapter at the USB port of your computer can use the WLAN software of your computer or a WLAN pro- gram of your own. No matter what program is used to estab- lish the WLAN connection, the principle is the same: the WLAN software searches for a WLAN radio network in the vi- cinity and, after authorization with a WLAN key, enables the WLAN connection between the FRITZ!Box and your WLAN de- vice.

1. Make sure that the WLAN function of the FRITZ!Box is en-

abled and the “WLAN” LED is on. If “WLAN” is not on, press the “WLAN” button briefly.

2. Start the WLAN software of your WLAN device. Consult

the documentation of your WLAN device for instructions.

3. Search for the WLAN radio network of your FRITZ!Box.

Upon delivery this network is called “FRITZ!Box WLAN 3370”.

4. Enter the WLAN key of the FRITZ!Box.

With this, the WLAN connection is established. Your WLAN de- vice is integrated into your home network and can use the In- ternet connection of the FRITZ!Box.Connecting WLAN Devices with the FRITZ!Box Guest Access FRITZ!Box 3370 57

11.2 Connecting WLAN Devices with the FRITZ!Box Guest Access

With the FRITZ!Box you can provide your guests with an Inter- net connection of their own. At this guest access they can surf the web with their own smartphones or tablets, but cannot access the contents of your home network. You can set up a guest access if you have connected the FRITZ!Box directly to your DSL line. If the FRITZ!Box is connect- ed in another way, for instance to a cable modem, you cannot set up guest access.

1. Open the FRITZ!Box user interface.

2. Make sure that the wireless radio network (WLAN) is en-

4. Assign a name for the guest wireless network (SSID) and

enter a WLAN key at least 20 characters long under “Se- curity”. This concludes the setup of your guest access. Now guests can register their WLAN devices with the FRITZ!Box.

1. Your guest starts the WLAN software of his WLAN device,

searches for your guest wireless network and enters the WLAN key you specified for authorization.

2. The WLAN connection will be established.

Your guest’s WLAN device can use the Internet connection of the FRITZ!Box, but has no access to your home network. For more information, see the Online Help.FRITZ!Box 3370 58 Switching the WLAN Radio Network On and Off by Schedule

11.3 Switching the WLAN Radio Network On and Off by Schedule

You can switch the WLAN radio network of the FRITZ!Box auto- matically according to a schedule. This function is called “night service” and reduces the power consumption of the FRITZ!Box by completely turning off the WLAN module. The FRITZ!Box Night Service also affects any other FRITZ! products connected in the network (FRITZ!WLAN Repeater, for instance) by switching the WLAN transmission of these devices on and off as well.

3. Enable the schedule for the WLAN radio network.

With the options “Switch WLAN off daily” and “Switch WLAN off according to schedule” you define the inter- vals of the schedule. You can also select the option “The radio network cannot be switched off until no more WLAN devices are active”. For more information on these settings, see the Online Help. Switching WLAN On and Off Manually You can switch the wireless radio network of the FRITZ!Box on and off at any time, even when the device is hibernating.

The range of a WLAN radio network is not specified. It de- pends on

In combination with the FRITZ!Box the AVM FRITZ!WLAN Repeater are especially suitable. All models of the FRITZ!WLAN Repeater series can be integrated into your WLAN radio network and your home network by WPS Quick Connection. Find out more in the Internet at: www.avm.de/en/Produkte/FRITZ_WLAN/FRITZ_WLAN_ Repeater_N_G Expanding a WLAN Radio Network with a WDS Repeater You can expand the WLAN radio network of your FRITZ!Box with what is called a WDS repeater. A WDS repeater can be a FRITZ!Box or any WLAN router you already have that can be configured as a WDS repeater to expand your WLAN radio net- work. See the documentation of your device to find out whether your existing WLAN router supports the WDS function and how to configure it as a WDS repeater. Your FRITZ!Box or an- other FRITZ!Box model can be configured as a WDS repeater by working through the following steps:

3. Select the “WLAN / WDS” menu and follow the instruc-

A wireless LAN radio network is based on standards defined by the Institute of Electrical and Electronic Engineers (IEEE). These standards describe, for instance, the transmission speeds, encryption methods and frequencies used in a wire- less LAN network. WLAN Standards The Institute of Electrical and Electronic Engineers (IEEE) de- fined the WLAN standards IEEE 802.11a, IEEE 802.11b, IEEE 802.11g, IEEE 802.11n and IEEE 802.11i for WLAN radio net- works. Standards for the Throughput Rate The throughputs listed differentiate between gross and net transmission rates. The net speed describes the transmission rate of the user data. The FRITZ!Box supports your choice of the standards IEEE 802.11a, IEEE 802.11b, IEEE 802.11g and IEEE 802.11n. WLAN devices based on one or more of the standards listed can be used for WLAN connections with the FRITZ!Box. The standards are intended for different frequency bands. The wireless LAN connection between your FRITZ!Box and a FRITZ!Box in WDS operation can be encrypted by WPA2. The wireless LAN connection between your FRITZ!Box and anoth- er wireless LAN router is only possible with less secure WEP encryption. Standard Frequency Band Gross Data Throughput up

Net Data Throughput up to 802.11b 2.4 GHz 11 Mbit/s 5 Mbit/s 802.11g 2.4 GHz 54 Mbit/s 25 Mbit/s 802.11a 5 GHz 54 Mbit/s 25 Mbit/s 802.11n 2.4 / 5 GHz 450 Mbit/s 200 Mbit/sWLAN—Getting Technical FRITZ!Box 3370 61 IEEE 802.11a Because this standard works exclusively in the seldom used 5-GHz range, it offers the opportunity to transmit data rela- tively free of interference from external influences. WLAN de- vices that support 802.11a are much less common than de- vices that work in accordance with the 802.11b/g standard. IEEE 802.11b With a maximum throughput rate of 11 Mbit/s, this is the old- est WLAN standard. Older WLAN devices of the first genera- tion can communicate with the FRITZ!Box using 802.11b. However, if the WLAN device supports newer standards such as 802.11g, the latest standard should be used. IEEE 802.11g This is currently the most common WLAN standard. It commu- nicates with a maximum of 54 Mbit/s gross in the 2.4-GHz frequency range (ISM) and guarantees broad compatibility with many WLAN devices. However, due to heavy use of the 2.4-GHz range, interference is more common than in the less-used 5-GHz range. IEEE 802.11n This standard allows for high throughput rates and ranges. The FRITZ!Box supports 802.11n in the 2.4-GHz frequency band, or, if desired, also in the 5-GHz frequency band. Modu- lation processes and antenna techniques like MIMO (Multiple Input, Multiple Output) use whichever frequency band is available more effectively than the older standards. Thanks to compatibility with the 802.11g standard, you can also continue to use older WLAN devices. The use of the 802.11n standard—and thus the availability of higher throughput rates—is possible only if the WLAN con- nection is secured using the WPA2 security mechanism (AES- CCMP).FRITZ!Box 3370 62 WLAN—Getting Technical Setting the Right Standard in the FRITZ!Box The throughput rate that can be achieved in your WLAN radio network depends on the WLAN standards used by the inte- grated WLAN devices. These WLAN standards must also be set in the FRITZ!Box. Proceed as follows to check which WLAN standards are set and change them if needed:

1. Open the FRITZ!Box user interface.

2. Enable the advanced view.

3. Open the “WLAN / Radio Channel” menu and select “Ad-

just radio channel settings” to make the desired chang- es.

• In order to communicate with each other, the FRITZ!Box and all WLAN devices must work in the same frequency band.

• The standard you configure in the FRITZ!Box must be compatible with the standards of all WLAN devices used in the WLAN. Make a note of which standards the WLAN devices in your network are compatible with and then adjust the FRITZ!Box settings according to the following information:

• Your radio network integrates only WLAN devices that are compatible with one or both of the following stan- dards: 802.11n 802.11g Set the following mode in the FRITZ!Box: Mode: 802.11n+g The 2.4-GHz frequency band will be used. Note the following for the configuration of this setting:WLAN—Getting Technical FRITZ!Box 3370 63

• Your radio network integrates only WLAN devices that are compatible with one or several of the following stan- dards: 802.11n 802.11g 802.11b Set the following mode in the FRITZ!Box: Mode: 802.11n+g+b The 2.4-GHz frequency band will be used.

• Your radio network integrates only WLAN devices that are compatible with one or both of the following stan- dards: 802.11n 802.11a Set the following mode in the FRITZ!Box: Mode: 802.11n+a The 5-GHz frequency band will be used.FRITZ!Box 3370 64 WLAN—Getting Technical The Standard for Security IEEE 802.11i The WPA2 security mechanism is defined in the IEEE 802.11i standard. WPA2 is an extension of the familiar security mech- anism WPA (Wi-Fi Protected Access). The main feature of the extension of WPA to WPA2 is the AES- CCMP encryption process. FRITZ!Box supports the AES encryption procedure as part of the WPA2 mechanism, and the TKIP encryption procedure as part of the WPA mechanism. This means that the FRITZ!Box can be used in combination with any WLAN devices that also support WPA2 with AES or WPA with TKIP. Frequency Ranges WLAN uses the frequency ranges at 2.4 GHz and 5 GHz as its transmission range. With the FRITZ!Box you can establish WLAN connections in ei- ther the 2.4-GHz or the 5-GHz frequency range. 2.4-GHz Frequency Band In the 2.4-GHz frequency band WLAN works in the same range as Bluetooth, microwave devices and various other devices like radio-controlled toys, garage-door openers and video bridges. This means that interference may occur within WLANs operated in the vicinity of such devices. Generally this has adverse effects on the transmission rate, including abort- ed connections. Mechanism Encryption WPA TKIP (Temporary Key Integrity Protocol) WPA2 TKIP AES-CCMP based on the extremely secure AES (Advanced Encryption Standard) procedure. CCMP (Coun- ter Mode with CBC-MAC Protocol) defines how the AES procedure is applied to WLAN pack- ets.WLAN—Getting Technical FRITZ!Box 3370 65 In the 2.4-GHz frequency range the European regulation au- thorities have designated 13 channels for WLAN. A channel can have a bandwidth of 20 MHz (throughput of up to 216 Mbit/s) or 40 MHz (throughput of up to 450 Mbit/s). Channels located directly next to each other in the 2.4-GHz band may overlap and result in mutual interference. For in- stance, if several WLANs are operated close to each other in the 2.4-GHz frequency range with a bandwidth of 20 MHz, a distance of at least five channels should be left empty be- tween each two channels used. This means that if channel 1 is selected for one WLAN, the channels 6 through 13 can be selected for a second WLAN. This maintains the minimum dis- tance between channels. Should interference in a WLAN persist, the first step should be to select a different channel. WLAN Autochannel With the WLAN autochannel function, the FRITZ!Box automati- cally searches for the channel subject to the least interfer- ence. This process takes into consideration interference from radio networks in the vicinity (WLAN base stations) and po- tential sources of interference (for instance video bridges, baby monitors, microwave ovens). Should problems with in- terference persist despite this function, try to identify the source of interference and switch it off manually. Additional tips on interference in the WLAN radio network are presented in the section Ruling Out Interference from Other Wireless Networks from page 101. 5-GHz Frequency Band The FRITZ!Box can operate in the 5-GHz frequency band as an alternative. This frequency range is used much less often than the most common 2.4-GHz frequency range. In the 5-GHz frequency band the FRITZ!Box supports automat- ic channel switching by DFS (Dynamic Frequency Selection). DFS ensures that the channels from 52 to 140 are kept free for higher-priority users, like weather radar systems. If you are operating your FRITZ!Box in one of these channels, itFRITZ!Box 3370 66 WLAN—Getting Technical monitors the selected channel periodically for higher-priority users, and, if necessary, switches to a different channel. Note that the FRITZ!Box waits up to ten minutes, as legally re- quired, before occupying a free channel. During this period you cannot register any WLAN devices. The WLAN connection is then established automatically. For more information, see the section Avoiding WLAN Channels with DFS on page 101. A prerequisite for use of the 5-GHz frequency band is that WLAN devices used in the network support this frequency range in accordance with the IEEE 802.11a or IEEE 8002.11n standard.

The FRITZ!Box works in the wireless network either in the 2.4-GHz range or in the 5-GHz range, but not parallel in both frequency ranges at the same time. Bandwidth In both frequency ranges you can select between channel bandwidths of 20 MHz or 40 MHz (exception: channel 140 in the 5-GHz frequency band). The FRITZ!Box initially attempts to select a channel with 40 MHz bandwidth. If this is not pos- sible due to interference or channels already being used by other WLANs in the vicinity, the FRITZ!Box automatically switches temporarily to a bandwidth of 20 MHz. Greater bandwidth provides for higher data throughput: Increasing bandwidths also increases the probability of inter- ference by wireless networks in the vicinity. Large bandwidths reduce the frequency range available to other wireless net- works in the vicinity. Bandwidth (MHz) Maximum Data Throughput (Mbit/s)

You will also learn how you can change the IP settings for the computer in the most common oper- ating systems.

13.1 Network Settings in the FRITZ!Box

The FRITZ!Box is delivered with preconfigured network set- tings. According to these settings, all network devices con- nected with the FRITZ!Box are located in a single network. The network settings can be changed and adapted to your conditions and needs. But you should do so only if you are well versed in networking technology. Network Overview The FRITZ!Box user interface shows an overview with all of the devices and users connected with the FRITZ!Box. The network overview “Devices and Users” is found in the menu “Home Network / Network”.

• For each user and each network device, you find an entry in the network overview. The columns have the following meanings:

• If you use FRITZ!Powerline devices in your network, then the FRITZ!Powerline devices are entered in the network overview along with the network devices connected to the FRITZ!Powerline devices.

• The network overview is divided into the areas “Active Connections”, “Guest Network” and “Idle Connections”. The Glossary (page 122) explains concepts and terminology having to do with IP networks.Network Settings in the FRITZ!Box FRITZ!Box 3370 71 For each user and each network device, you find an entry in the network overview. The columns have the following mean- ings: Accessing Network Devices by Mouse Click Network devices that can be reached over the http protocol can be accessed within the home network by the click of a mouse. Clicking the device name opens the user interface of the http application. Icon A green LED before the device name indicates that a device is actively connected with the FRITZ!Box, but not using the Internet connection at this time. A green-blue globe indicates that the device is cur- rently using the Internet connection. Name This column displays the name under which the user or the network device is known to the FRITZ!Box. The names of network devices can be changed by clicking the button to edit the entry. IP Address For network devices, also displayed is the IP ad- dress with which the device is integrated into the FRITZ!Box network. Connection The WLAN icon is displayed for wireless connec- tions. Properties This column indicates whether port forwarding or child protection is enabled for the respective user or network device. Button for editing the entry The button opens the entry in editing mode. This view displays information about the network de- vice, for instance on child protection or port for- warding settings. The name of the device in the FRITZ!Box can be changed here. Button for deleting the entry Users or network devices that do not have an ac- tive connection to the FRITZ!Box can be deleted from the network overview by clicking this button.FRITZ!Box 3370 72 Network Settings in the FRITZ!Box Always Assigning the Same IP Address The editing mode for network devices includes the setting “Always assign this network device the same IP address”. When this setting is enabled for a network device, the DHCP server of the FRITZ!Box will always assign the same IP address to this device each time the connection is established. Starting the Computer—Wake on LAN The Wake on LAN function of computers can be enabled in the editing mode for network devices. The computers must sup- port wake on LAN and be connected with the FRITZ!Box with a network cable. The wake on LAN function is also available when the devices are connected via FRITZ!Powerline devices. Wake on LAN is a function that allows a computer in the local network to be started when it is accessed from the Internet. For instance, you can access a computer using remote main- tenance software, without wasting electricity by keeping the computer switched on permanently. The computer must be in standby operation. The FRITZ!Box supports Wake on LAN both for IPv4 and for IPv6 connections.

• The “Start Computer” Button You can start the computer each time it is accessed over the Internet by clicking the “Start Computer” button.

• Starting Automatically To do this, enable the setting “Start this computer auto- matically as soon as it is accessed from the Internet”. When the computer is accessed from the Internet, it is started automatically.Network Settings in the FRITZ!Box FRITZ!Box 3370 73 IPv4 Settings in the FRITZ!Box The IPv4 settings of the FRITZ!Box are preset upon delivery with the following values: The IP address and the corresponding subnet mask yield the following values: The following IPv4 addresses cannot be assigned because they are reserved for certain purposes: IP Address in Case of Emergency The FRITZ!Box has a fixed IP address that cannot be changed.

If you would like to change the IPv4 address, please read through the following sections. When Does It Make Sense to Change the IPv4 Address? You should change the IPv4 address of the FRITZ!Box if the following apply to your network:

• You have an existing local IPv4 network, one subnet with several computers.

• Fixed IPv4 addresses are registered in the network set- tings of the computer, and you do not want to or are not permitted to change these addresses.

• You want to connect the FRITZ!Box to the local IPv4 net- work in order to make the FRITZ!Box features available to all of the computers in the IPv4 network. Reserved IP Addresses The entire IP network 192.168.180.0 in the FRITZ!Box is re- served for internal purposes. IPv4 addresses from this network may not be assigned to the FRITZ!Box. DHCP Server for IPv4 The FRITZ!Box is equipped with its own DHCP server for the IPv4 network. The DHCP server is enabled by default in the factory settings. The following range of IP addresses is re- served for the DHCP server in the factory settings:

192.168.178.20 - 192.168.178.200

This IP address can be changed as needed. Every time the operating system on a computer connected with FRITZ!Box is started, the DHCP server assigns it an IPv4 address from the IP address range of the DHCP server.Network Settings in the FRITZ!Box FRITZ!Box 3370 75 Assigning the IP addresses via the DHCP server ensures that all of the computers connected with the FRITZ!Box are located in the same IP network. Fixed IPv4 Addresses When the DHCP Server Is Enabled If you would like to configure fixed IPv4 addresses on individ- ual computers connected with the FRITZ!Box despite the en- abled DHCP server, please note the following:

• The IPv4 addresses must be from the IPv4 network of the FRITZ!Box.

• The IPv4 addresses may not come from the address range of the DHCP server.

• Each IPv4 address can be assigned only once. Disabling the DHCP Server You can disable the DHCP server. To make sure that all computers remain in the same IP net- work when the DHCP server is disabled, you must enter the IPv4 addresses manually in the computers’ network settings. First disable the option “Obtain an IP address automatically” and then enter the IP address manually in the appropriate field. In the case of the preset IPv4 address of the FRITZ!Box, the following IPv4 addresses are available for assignment to the computers: Only one DHCP server may be active within any network. The computers can receive their IPv4 addresses from the DHCP server only if the setting “Obtain an IPv4 address auto- matically” is enabled in the their IP settings. For more infor- mation, see the section Obtaining an IP Address Automati- cally from page 78.

Alternatively, the network devices can identify the local DNSv6 server via DHCPv6. IPv6 Settings Click the “IPv6 Addresses” button to configure settings for the IPv6 addresses in the local network. Here too: each IPv4 address can be assigned only once. Please note that changes to the network settings in the FRITZ!Box may make it necessary to adjust the network set- tings of your computers so that you can continue to access the FRITZ!Box user interface.Network Settings in the FRITZ!Box FRITZ!Box 3370 77 Unique Local Adresses The communication within the local network takes place via the Unique Local Addresses (ULA). If no IPv6 Internet connec- tion is established, the network devices do not have a ULA and communication between them is restricted. For this case you can set the FRITZ!Box such that the network devices re- ceive the ULA from the FRITZ!Box. DHCPv6 Servers in the Home Network The FRITZ!Box is equipped with its own DHCPv6 server. The DHCPv6 server of the FRITZ!Box is switched on by default. The DHCPv6 server assigns the network devices their IPv6 settings. These settings are used instead of the data in the router advertisement messages. The DNS server, IPv6 prefix- es or IPv6 addresses can all be assigned by DHCPv6. Define which IPv6 settings should be assigned by the DHCPv6 serv- er. UPnP Settings The Universal Plug-and-Play (UPnP) service included in your FRITZ!Box provides status information about the FRITZ!Box to all connected computers. Programs with UPnP support on these computers can receive this information and use them to display the status of the FRITZ!Box (e.g., connection status, data transmission). UPnP service thus allows you to monitor your FRITZ!Box from a connected computer. Here is how to change the UPnP settings:

1. Open the FRITZ!Box user interface (see page 26).

2. Enable the advanced view.

3. Configure the UPnP settings in the “Home Network / Net-

All network devices in the FRITZ!Box home network can use these USB devices jointly and simultaneously. This chapter describes how to share a printer in the network, which USB devices can be used in your FRITZ!Box home network, and how to use these devices safely.

14.1 Power Supply for USB Devices

You can connect USB devices with the following properties to the FRITZ!Box:

• Some USB devices require more than one USB port for operation, for instance, hard drives with a USB Y cable. Connect this type of USB devices to the FRITZ!Box using a USB hub with its own power supply.

• The total current consumption of connected USB devices without their own power supply may not exceed 500 mA. Check the rating plates of the connected USB devices. USB devices that exceed the total current consumption of 500 mA can be connected to the FRITZ!Box using a USB hub with its own power supply.

14.2 USB Devices on the FRITZ!Box

These USB devices can be connected to the FRITZ!Box:

• You can connect up to four USB storage media like hard disks, USB flash drives or card readers.

• USB storage media must use the file systems EXT2, FAT, FAT32 or NTFS. On storage media with the FAT and FAT32 file systems you can use files up to a size of 4 GB. In the EXT2 and NTFS file systems there is no limit to the size of files that can be used.

• You can connect one standard USB printer or one all-in- one device with scanner and fax function. The complete range of functions available in a all-in-one printersFRITZ!Box 3370 82 Using USB Devices Safely device is guaranteed only with the USB remote connec- tion of the FRITZ!Box (see also: Sharing a USB Printer on page 84).

• You can connect a USB hub to the FRITZ!Box and use up to four USB devices at this hub. You can use USB hubs with or without a separate power supply. We recommend deploying a USB hub with its own power supply if the USB devices to be connected ex- ceed a total current consumption of 500 mA (see also: Power Supply for USB Devices on page 81).

• You can connect a USB stick from the FRITZ!WLAN USB Stick series by AVM to conveniently establish secure WLAN connections using AVM Stick & Surf (see: Establishing a WLAN Connection with AVM Stick & Surf on page 20).

14.3 Using USB Devices Safely

Follow the instructions below about how to use USB devices on your FRITZ!Box.

• The FRITZ!Box can not defend the USB memory from ex- ternal influences. This means that voltage spikes or drops, like those that occur during electrical storms, may lead to data losses on connected USB storage media. We recommend making regular backups of the USB memory contents to avoid any losses.

• Whenever you want to remove USB devices from the FRITZ!Box, go to the “Home Network / USB Devices” area in the FRITZ!Box user interface to remove them safely and avoid any loss of data.

14.4 Configuring Password Protection and Access Rights

To protect the data on your USB memory from unauthorized access, you can set up a password and access rights. Both the password protection and the access rights are valid on all memory available in the FRITZ!Box home network. You can not assign special passwords or access rights for individual storage media.Accessing USB Memory FRITZ!Box 3370 83

14.6 Sharing a USB Printer

You can connect a USB printer to the USB port of the FRITZ!Box to make it available to all participants in your home network. You can either release the printer for sharing as a network printer or use the FRITZ!Box USB remote connection software to connect it with a computer. Which option is pref- erable depends on how you intend to use the printer. Using a USB Printer as a Network Printer Configure the USB printer as a network printer on the FRITZ!Box if

• the participants in the home network are to be able to use the printer jointly and simultaneously.

• the printer is to be used by computers that use an oper- ating system other than Windows (e.g. Mac OS X or Linux). For information about how to configure a USB printer as a net- work printer, see the section Setting Up a USB Printer as a Network Printer on page 85. Using a USB Printer with FRITZ!Box USB Remote Connection Configure the USB printer on the FRITZ!Box with the FRITZ!Box USB remote connection if

• the USB printer is an all-in-one device (fax/printer/scan- ner) and the entire range of functions is to be used.

• the USB printer is equipped with convenience features like ink level display and you would like to use these.Sharing a USB Printer FRITZ!Box 3370 85

• the USB printer uses bidirectional data exchange. In oth- er words: Not only does the computer send data to the printer, the printer also sends status messages to the computer. This communication in both directions is typi- cal of the “Windows printers” or “GDI printers” that work only with special Windows device drivers. For information about how to configure a USB printer with the USB remote connection, continue reading from the section Configuring a USB Printer with FRITZ!Box USB Remote Con- nection on page 88.

This means that you gen- erally use much less power with the FRITZ!Box than you would with sev- eral separate devices. What is more, the FRITZ!Box saves energy by reducing processing power on standby and lowering the power consumption of idle functions. The FRITZ!Box also offers various settings for energy-saving operation.

15.1 Saving Energy with the WLAN Radio Network

You can reduce the power consumption of the WLAN radio network by

• setting up night service for the WLAN radio network (see page 58).

• turning off the WLAN radio network with the “WLAN” but- ton whenever no more WLAN devices are registered on the FRITZ!Box.

• adjusting the setting “Maximum transmitter power” to the percentage level actually needed. This setting is con- figured in the “WLAN / Radio Channel” menu in the FRITZ!Box user interface.

15.2 Enabling Energy-saving Mode for USB Hard Drives

In the FRITZ!Box you can enable an energy-saving function for USB hard drives connected to the FRITZ!Box. When the energy-saving function is enabled, connected USB hard drives will be switched off when they are idle—as long as the hard drives support the energy-saving function. The current energy consumption of the total FRITZ!Box sys- tem is displayed on the “Overview” page. From there, click with the mouse to view the Energy Monitor, which displays details on the energy consumption.Saving Energy at the LAN Ports FRITZ!Box 3370 91 Enable the energy-saving function in the “Home Network / USB Devices” menu in the FRITZ!Box user interface.

Enable WLAN encryption right away after completing the tests. Cause HelpCannot Establish a WLAN Connection FRITZ!Box 3370 101 Avoiding WLAN Channels with DFS The FRITZ!Box loses the WLAN connection in the 5-GHz frequency band for no apparent reason. A forced channel change is taking place. In the 5-GHz fre- quency band the WLAN base station is programmed to change the channel whenever a radar source transmits on the same channel (Dynamic Frequency Selection, DFS). You can prevent forced channel changes by selecting in the FRITZ!Box a channel for the 5-GHz frequency band that does not use DFS (channels 36, 40, 44, 48). Ruling Out Interference from Other Wireless Networks If there are other devices in the immediate vicinity of your FRITZ!Box that use the same frequency band, mutual interfer- ence and interrupted connections can occur. Devices that can cause disruptions include other WLAN base stations, baby monitors, game consoles, garage door openers, Bluetooth devices, or wireless AV bridges, which also use the 2.4-GHz frequency band. If such devices are located in the vicinity of the FRITZ!Box, test a different radio channel for the FRITZ!Box or switch the radio channel setting to “Autochannel”. Then the FRITZ!Box will automatically set the best WLAN channel for transmis- sion. For applications that rely on a high throughput rate (“stream- ing”), you should use the 5-GHz frequency band. This fre- quency band provides more channels and is subject to signif- icantly less external interference.

Designates a fast kind of data transmission that works with standard copper cables and transports signals in both direc- tions at different speeds (upstream at 640 Kbit/s and down- stream at up to 9 Mbit/s). ADSL2 short for Asymmetric Digital Subscriber Line 2 ADSL2 (G.992.3) is a further development of the ADSL stan- dard. ADSL2 offers range much greater than did the first ADSL gen- eration, and is significantly more robust than ADSL, as it can simply disable single carrier frequencies when they produce interference. This feature allows ADSL2 to prevent synchroni- zation losses. With a throughput rate of up to 12 Mbit/s downstream, ADSL2 offers considerably greater bandwidth than ADSL. ADSL2 is completely downward compatible, meaning that ter- minal devices compliant with ADSL can also be operated on ADSL2 lines, although they cannot exploit the advantages of ADSL2. In practice ADSL2 has become less important since the ADSL2+ standard has made higher throughput rates possible. ADSL2+ short for Asymmetric Digital Subscriber Line 2 with extended bandwidthGlossary FRITZ!Box 3370 123 ADSL2+ (G.992.5) is a further development of the ADSL stan- dard. ADSL2+ offers a doubled frequency range used for down- stream transmission, and thus double the maximum band- width achievable for downstream to 24 Mbit/s. ADSL2+ is completely downward compatible, meaning that terminal devices compliant with ADSL and ADSL2 can also be operated on ADSL2+ lines, although they cannot exploit the advantages of ADSL2+. DDNS short for Dynamic Domain Name System DDNS is a service which allows a computer always to be reached under the same domain name despite constantly changing public IP addresses. This means the home network can always be reached from the Internet, regardless of the us- er’s location. Even private users have an economical way of placing their own Internet offers on their computer at home. Every time the Internet connection is established, the Internet service provider assigns a new public IP address. Each time the IP address changes, the current IP address is transmitted to a special DDNS server. Except for the few sec- onds between the cancellation of the old IP address and the notification of the new IP address, the computer can always be reached at the selected domain name. default gateway Gateway (see glossary) DHCP short for Dynamic Host Configuration Protocol DHCP is a protocol for dynamically negotiating the operating parameters of the TCP/IP protocol (see glossary). The com- puters in a local IP network (DHCP clients) access the DHCP server as part of their operating systems’ start procedure.FRITZ!Box 3370 124 Glossary The central administration of the TCP/IP operation parame- ters makes it possible to avoid address conflicts caused by IP addresses (see glossary) accidentally assigned more than once. DHCP is used in IPv4 networks (see glossary). DHCP server The DHCP server assigns each client an IP address that it has not yet been assigned at the present time. The DHCP server also informs the client of the IP addresses of the DNS server to be used and of the default gateway. In assigning the IP ad- dresses the DHCP server selects from a prescribed range of IP addresses. DHCP is used in IPv4 networks (see glossary). DNS short for Domain Name System Domain Name Service takes care of determining the IP ad- dress for a given domain name. This Domain Name Service runs on every computer. It accepts the domain name entered by a user and inquires about the corresponding IP address at a DNS server known to the service. If a DNS server cannot an- swer the inquiry itself, it can inquire about the IP address (DNS resolution) at other DNS servers. If the Domain Name Service receives negative information from the DNS server (domain name not known), it can send inquiries to other DNS servers it knows or return a corre- sponding error message to the user. If it receives the desired IP address instead, the application can use the IP address to retrieve the destination desired by the user. This hierarchical system of DNS servers is known as the Do- main Name System. The addresses of the DNS servers at which the Domain Name Service is to inquire by default gen- erally are handed over to the computer by the Internet service provider automatically whenever a connection to the Internet is established.Glossary FRITZ!Box 3370 125 download Download designates the transfer of files from the Internet to a computer. DSL modem A DSL modem connects a computer to the Internet via the DSL line. In contrast to the analog modem, a connection via the DSL modem does not mean that the telephone line is busy. DSL router A DSL router generally combines three different devices: a DSL modem (see glossary), a router, and a LAN switch. A DSL router serves, first, to connect multiple computers or other network devices together to form a local network (LAN) so that the devices can exchange data with each other. Second, a DSL router provides a central Internet connection that can be used by all devices in the home network at the same time. The DSL router’s job is to control the data traffic between the local network and the Internet. If the DSL router is equipped with a firewall (see glossary), it protects the de- vices in the home network against attacks from the Internet. DSL splitter A DSL splitter is a device that separates telephone and DSL signals. You need a DSL splitter if you have a fixed line (see glossary) and a DSL line. The splitter separates the telephone and DSL signals, which use the same cable to access your house or apartment. The splitter conducts telephone signals to your analog telephones or to the NT (see glossary). DSL signals are sent on to the DSL modem or DSL router. dynamic IP address A dynamic IP address is an IP address valid only for the dura- tion of one Internet or network session.FRITZ!Box 3370 126 Glossary Every computer participating in the Internet must have a uniquely assigned public IP address. Since only a limited number of such IP addresses is available, they must be used sparingly. That is why most of the Internet participants who dial in to the Internet receive a dynamic IP address. They are called dynamic because every participant receives a new public address that has not been assigned yet each time she or he connects to the Internet. By contrast, dynamic addresses are usually used in local IP networks because they are easy to handle, and because us- ing them avoids incorrect IP address entries or unintentional double assignments. file system A file system saves and manages files on a data medium (for instance, a hard drive or flash drive). The way the files are stored varies from one file system to the next. The different operating systems offer different file systems. In Windows 7, Windows Vista and Windows XP the file systems FAT32 and NTFS are used most frequently. The file system of a data storage medium can be changed, for instance from FAT32 to NTFS. fixed IP address Fixed IP addresses are IP addresses (see glossary) which are permanently assigned to a computer or another device like a network printer. Assigning fixed IP addresses makes sense in cases where a computer is always supposed to be accessible at a certain ad- dress (for instance, a web server or an e-mail server). fixed line A fixed line is a telephone line in the classic, landline tele- phone network. There are two kinds of fixed lines: analog lines and ISDN lines.Glossary FRITZ!Box 3370 127 If you have a fixed line and a DSL line, the signals for both lines use the same cable to access your house or apartment. For this reason your telephony and Internet service provider supplies you with a DSL splitter (see glossary) that separates the telephone signals and DSL signals from each other. firewall A firewall protects a computer or local network against at- tacks from the Internet. Most firewalls work with packet filters, which merely check the IP addresses and port numbers of incoming and outgoing data packets and filter the packets according to prescribed rules. Within IPv4 networks, some firewalls also integrate addition- al concepts like IP masquerading and NAT to decouple data traffic by distinguishing strictly between the internal and ex- ternal network. Especially effective firewalls go even further, analyzing and evaluating the contents of the packets and filtering them ac- cording to prescribed rules. Such techniques may also in- clude a Stateful Packet Inspection Firewall, for instance. firmware The firmware is the software of an electronic device, which is stored in the device and controls its functions. FTP short for File Transfer Protocol The File Transfer Protocol allows files to be exchanged be- tween two computers in the Internet. A computer on which the files are made available for downloading is called an “FTP server”. A special program is required for downloading files, known as an “FTP client”. Some web browsers contain FTP cli- ents, but they are also available as independent software.FRITZ!Box 3370 128 Glossary gateway Gateway is a general term designating an interface between two networks. Such a network interface can be realized using a router or a bridge, for instance. If a computer wants to transfer data packets to a computer in another network, it must first transmit the packet to the gate- way. To do this, the computer must know the address of the gateway. If all packets that cannot be delivered in a local network al- ways are to be transmitted to their given recipients via the same gateway, for this purpose the address of the gateway must be saved as the default gateway in the network settings of the computer. If a router is used for the shared Internet access in a local net- work, the IP address of the router must be entered as the de- fault gateway in the TCP/IP settings of each computer that wishes to use the Internet connection. HSPA short for High Speed Packet Access HSPA is a third-generation mobile radio standard further de- veloped from the the UMTS mobile radio standard. HSPA pro- vides for throughput rates in the mobile radio network that are comparable with DSL (3.6 to 13.98 Mbit/s). hub A hub is a device that is used to connect network devices to each other, for instance through an Ethernet. Network devices are connected to each other in a star network, with each net- work device connected to the hub. There are no direct con- nections between the network devices. A hub can either send or receive data. Received data are sent to all connected devices. All connected devices share the da- ta throughput.Glossary FRITZ!Box 3370 129 Internet telephony VoIP (see glossary)

short for Internet Protocol The IP Internet Protocol is the most important basic protocol for the control of data exchange in local networks and in the Internet. The Internet protocol works without a connection; in other words, data packets are transmitted from the sender to the recipient without previous consultation. The addresses of the recipient and the sender in the data packets are given as IP addresses. IPv4 short for Internet Protocol version 4 IPv4 is currently the conventional Internet protocol. IPv4 addresses are 32 bits long, such that IPv4 offers an ad- dress space of 2

IP addresses, or just over four billion. The latest estimates suggest that the last IPv4 addresses will be assigned by the beginning of 2012. The successor protocol to IPv4 is IPv6. IPv6 short for Internet Protocol version 6 IPv6 is the successor protocol to IPv4. IPv6 addresses are 128 bits long. This means that IPv6 makes approximately 340 undecillion (~ 3.4 x 10

) IPv6 ad- dresses available. Each private user can be allotted over 18 quintillion public IPv6 addresses from her or his Internet service provider. The dearth of addresses in IPv4 is only one of the reasons for introducing IPv6. IPv6 also offers additional advantageous characteristics in the framework of communication within IP networks.FRITZ!Box 3370 130 Glossary IP address In IP-based networks, for instance in the Internet and local networks, all connected devices are addressed via their IP ad- dresses. So that data packets are sure to be delivered to the right address, each IP address may be assigned only once within the local IP network. IPv6 addresses are structured differently from IPv4 address- es. IP addresses can be written in decimal, octal or hexadeci- mal format. IP masquerading IP masquerading is a technique used within IPv4 networks. With IP masquerading a computer or LAN can be protected from unauthorized connection requests from the Internet. Masquerading works by converting the IP addresses used in a network to one public IP address. From the outside it appears as if all requests are sent from a single computer. IP network A network in which data exchange takes place on the basis of the Internet Protocol (IP) is called an IP network. NAS functionality NAS is short for Network Attached Storage NAS designates one or more devices that are integrated into a network to provide storage space. In connection with the FRITZ!Box, NAS functionality means that various services for connected USB storage media are available in the FRITZ!Box so that it easier for you to use your data and make them available in the local network. It is easy to exchange documents in the local network via the storage medium on the FRITZ!Box. The media server makes music, im- ages and videos in the network available to compatible play- back devices. Files can also be released for sharing in the In- ternet, and local memory expanded by adding online storage.Glossary FRITZ!Box 3370 131 NAT short for Network Address Translation NAT is a technique used within IPv4 networks. NAT is used in routers to replace the address information in data packets with new address information. A typical application for NAT is routers that connect local networks with the Internet. In local networks, every network device has a private IP address, while generally there is only one public IP address available for the Internet. To grant the network devices access to the In- ternet, the router replaces the private IP address of the send- er with its own public IP address in all outgoing data packets. The router saves all necessary information in a table so that incoming data packets can then be assigned to the correct network device. NTBA short for Network Termination for ISDN Basic Rate Access The NT is the network termination device on the ISDN basic rate terminal. The ISDN terminal devices are connected to the NT, for instance the ISDN telephone system (PBX) or ISDN telephones. public IP address A public IP address is an IP address (see glossary) valid in the Internet. Every computer or router participating in the Internet must have a uniquely assigned public IP address. This ad- dress is usually negotiated dynamically with the Internet ser- vice provider when a connection to the Internet is dialed. The Internet service provider assigns the negotiated IP address to the computer or router for the duration of an Internet session. port So that a single network connection on a computer can be used by multiple applications to exchange data with remote sites at the same time, a computer administers what are known as ports for the IP-based protocols TCP and UDP. Ports substantiate the point of access for the data packetsFRITZ!Box 3370 132 Glossary delivered via the IP Internet protocol. While the IP address de- termines the destination computer quite generally, the port addresses the communication interface provided by an appli- cation for a certain communication procedure. The Internet protocol allots 16 bits for the specification of the port number. Thus a total of 65,535 different port numbers can be specified. Ports up to port number 1,024 are reserved for special system applications and typical Internet applica- tions. These include, for instance, the port numbers 21 for FTP (File Transfer Protocol), 25 for SMTP (Simple Mail Transfer Protocol), 53 for DNS (Domain Name Service) and 80 for HTTP (Hypertext Transfer Protocol). Ports are primarily of interest to users for their role in protect- ing an Internet connection from external attacks. Most fire- walls offer the possibility of preventing data traffic on certain ports. This means that certain port numbers can be blocked to prevent data from being delivered to system services. This is also a way of preventing any Trojans (malicious applica- tions opening backdoors on computers) that may have infect- ed your computer from receiving data on ports it created as means of accessing your computer for potentially damaging activities. A firewall blocks most of the atypical port numbers not required for normal operation of an application and offers specialized users the opportunity to forward specified ports. port forwarding With port forwarding it is possible to specify ports that will al- low all incoming or outgoing data packets to pass through a router or firewall. If a computer from the local network offers server services, for instance, the settings of a router using NAT (see glossary) or IP masquerading (see glossary) must enable or forward the port used by the server service for access to incoming data packets and thus keep it open permanently. The private IP ad- dress of the given computer must be saved as the destination address for all of the packets arriving at the port.Glossary FRITZ!Box 3370 133 Typical server applications that require port forwarding are FTP and web servers. To allow access to a computer via re- mote management software like Symantec pcAnywhere or Mi- crosoft’s Remote Desktop, or even use of a file-sharing pro- gram like eDonkey, the required ports must be released for port forwarding. Port forwarding settings for the most impor- tant application cases are quite simple as long as the set- tings of the router or the firewall already contain rules with a corresponding preconfiguration. private IP address Private IP addresses are used for computers and other net- work devices within local IPv4 networks. Since many local IP networks are not connected to the Inter- net except via single computers or routers (gateway), certain address ranges are excluded from the publicly available IP addresses so that they are available for assignment in local IP networks. An IP address may be assigned only once within the local network. A private IP address may exist in any num- ber of other local networks. remote configuration TR-069 (see glossary) splitter DSL splitter (see glossary) Stick & Surf Stick & Surf is a technique developed by AVM for the fast, simple, error-free and secure configuration of radio networks. This technique allows for the straightforward transmission of all important parameters of a radio network from the WLAN base station to any computer that is to be added to the radio network. In this process the radio parameters used, including the WLAN channel, SSID and WLAN standard used, as well as se- curity parameters like the encryption method and networkFRITZ!Box 3370 134 Glossary key, are transferred almost fully automatically from the WLAN base station to the computer with the WLAN client that is to be connected. subnetwork A local IP network can consist of one subnetwork or be divid- ed into multiple subnetworks. The division into subnetworks is performed when the local IP network is configured. The subnetworks of a local IP network are also IP networks (see glossary). subnet mask The subnet mask indicates which part of an IP address (see glossary) is the network address and which the address of the computer. The network address defines what is called the subnet. switch A switch is a device that connects multiple network devices with each other, for instance through an Ethernet. In contrast to a hub, a switch can establish direct connections between the connected devices. This makes it possible to send data packets directly to specific recipients. The entire data throughput is at the disposal of every con- nected device. TCP/IP short for Transmission Control Protocol / Internet Protocol TCP/IP is the “language” of the Internet. TCP/IP is used to re- fer to a suite of protocols used for data communication over the Internet. TCP and IP are the network and transport proto- cols underlying most Internet services, including file transfer (FTP) and e-mail communication (SMTP). TCP/IP is available for practically all computer systems. TCP/IP thus offers the advantage of trouble-free communication between otherwise incompatible networks and systems.Glossary FRITZ!Box 3370 135 TR-069 TR-069 is a technical directive that simplifies the automatic configuration of Internet access devices like the FRITZ!Box. TR-069 describes the remote configuration of Internet access devices. In remote configuration the access and account data are automatically transmitted to the FRITZ!Box by the Internet service provider. These may include the account data for the Internet connection, Internet telephone numbers and login data for Internet telephony, or both. The Internet service provider saves the data to be transmitted on what is called an Auto Configuration Server (ACS). When the FRITZ!Box is connected with the broadband line (for in- stance, DSL), the data can be transferred automatically from the ACS to the FRITZ!Box. This relieves the user of the task of manually setting up the Internet and/or Internet telephone numbers in the FRITZ!Box. Encryption and ID verification ensure that the automatic con- figuration of the FRITZ!Box can not be intercepted or per- formed by unauthorized parties. Automatic configuration of the FRITZ!Box is possible only if the Internet service pInternet service providerrovider sup- ports remote configuration with TR-069. Which data are trans- ferred to the FRITZ!Box and how remote configuration is start- ed depends on the provider. For some providers, for instance, the user must enter a start code in the FRITZ!Box user inter- face. UMTS short for Universal Mobile Telecommunications System UMTS is a third-generation (3G) mobile radio standard with throughput rates of 384 Kbit/s to 7.2 Mbit/s. The high throughput rates make it possible to support multi- media services. With special cards or USB sticks the Internet connection can also be provided for laptops or computers via UMTS.FRITZ!Box 3370 136 Glossary update A more recent version of software or firmware is called an up- date. Updates are often free of charge, resolve minor pro- gramming errors, and sometimes also offer new functions. uplink port The uplink port on a hub or switch is designed for connecting another hub or switch, or a router. In contrast to the uplink port, there is also a user port for connecting terminal devices. The send and receive directions are transposed on the uplink port. On some devices the port can change between normal and uplink mode by means of a switch. upload This term designates the procedure of transmitting files from one’s own computer to another computer in the Internet. UPnP short for Universal Plug and Play (UPnP) UPnP is an extension of the Microsoft Plug & Play standard that allows devices to network globally and to exchange ser- vices—without a central server or computer. UPnP allows devices from all kinds of manufacturers (stereo systems, routers, printers, house controls) to be controlled via an IP-based network (see glossary), with or without cen- tral control through a gateway. It is based on a number of standardized network protocols and data formats. Expressed simplistically, devices can communicate with each other au- tomatically using UPnP to exchange information. Today the UPnP forum specifies the UPnP standard and certi- fies devices that are compliant with this standard. UPnP AV short for Universal Plug and Play Audio/VideoGlossary FRITZ!Box 3370 137 UPnP AV is a UPnP specification for the interaction between the media server, playback devices and devices controlling the streaming (transmitting a data stream) of audio, image and video data within networks. Media servers are devices that make audio, image and video data available upon re- quest. Playback devices render the audio, image and video data (television, stereo system, streaming clients). Control devices are remote controls (smartphone, remote control). USB short for Universal Serial Bus The Universal Serial Bus is an interface for transferring data between a computer and connected devices. It was intro- duced in 1996. Today nearly all computers have multiple USB ports. USB is used, for instance, to connect many keyboards, mice, printers and external hard drives to the computer. By now many other devices also have a USB port. For in- stance, many DVD and Blue-ray players can play back images, videos and music directly from a USB storage medium (hard drive, flash drive). The Universal Serial Bus supports hot plugging. This means that USB devices can be connected without turning the com- puter off. The Universal Serial Bus also offers a 5-Volt power supply. This makes it possible to load devices at the USB port and operate USB devices that do not have a power supply of their own. The Universal Serial Bus was introduced with the USB 1.0 specification in 1996. In 1998 came the reworked USB 1.1 specification, followed in 2000 by USB 2.0. With 480 Mbit/s, USB 2.0 provides for considerably higher throughput rates than USB 1.0/1.1 (12 Mbit/s). VDSL short for Very High Speed Digital Subscriber Line In Germany, the DSL technology VDSL is increasingly becom- ing available in the VDSL2 (G993.2) version. VDSL2 is a fur- ther development of the ADSL2+ standard, to which it is fullyFRITZ!Box 3370 138 Glossary downward compatible. The standard provides for throughput rates of up to 100 Mbit/s for uploading and downloading, but requires a distribution network with a more closely meshed infrastructure—a demand that is hardly economical outside of major urban areas. VPN short for Virtual Private Network VPN serves to integrate devices from a neighboring network into your own network, without the networks having to be compatible with each other. A VPN is generally an independent company network distrib- uted over several locations, which uses the infrastructure of a public communications network to link its partial networks or to link individual computers to the rest of the network. A VPN uses tunneling technologies and typically builds on the infra- structure of the Internet. Using a Virtual Private Network it is possible to use all net- work applications of the company network even from distant locations. This means it is possible to use the advantages of the network even over large geographical distances. VPN facilitates optimum information flow without delay throughout the entire company, even to offices in other loca- tions. E-mail servers, file sharing and other central applica- tions of the company network can thus be made available via VPN even to distant branch offices, subsidiaries and home of- fices. With VPN, field representatives of a company can also be granted secure access to the company network. VoIP short for for Voice over IP, also known as Internet telephony Calls from the Internet are possible to and from the fixed-line network and mobile communications networks. Various Inter- net service providers and telephony carriers provide SIP- fixed-line gateways for this purpose. The gateways are used to produce voice connections between the Internet and conventional telephone networks.Glossary FRITZ!Box 3370 139 In principle, VoIP calls can be made over any Internet connec- tion. However, for convenient use with existing terminal de- vices, and for conversations with the fixed-line and mobile communications networks, it is important that the Internet service provider support what is known as the SIP standard. SIP is the current standard defined for VoIP by the IETF (Inter- net Engineering Task Force). WLAN short for Wireless Local Area Network The term WLAN designates the industry standard for wireless local networks passed by the Institute of Electrical and Elec- tronics Engineers (IEEE) in 1997 under the title IEEE 802.11. By means of WLAN technology, individual computers or net- work devices like printers or DSL access points can be linked wirelessly to an existing cable-connected local network (LAN), or LANs can be converted completely to a wireless structure. A further useful purpose for WLAN technology is to link seg- ments of existing cable-connected networks. Although WLAN was actually developed only for short-range connections, by cascading WLAN base stations or implement- ing transmission networks with high-power point-to-point ra- dio transmission, even network segments located further away from each other can be linked or network participants in relatively remote locations can be economically and easily in- tegrated into an existing network. WLAN base stations often also serve as access points to the Internet in private or public institutions. Many airports, hotels and cafes, for instance, make WLAN hotspots available to their customers, either free or subject to a charge. Ultimately this has maneuvered WLAN into serious competition with mo- bile UMTS technology. The application possibilities for wireless network communi- cation also overlap with Bluetooth technology. For mobile de- vices with limited energy capacity Bluetooth is the more use- ful solution, however, as Bluetooth uses considerably lessFRITZ!Box 3370 140 Glossary power than wireless LAN. What is more, Bluetooth technology is more flexible and thus can offer a greater bandwidth of po- tential applications.FRITZ!Box 3370 141 Index
