Chapter 2 - Quick Start

Overview

This chapter describes the setup procedure to connect the wireless access point to your LAN, and configure it as an access point for your wireless stations.

Wireless stations may also require configuration. For details, see Appendix C - Wireless Station Configuration (p. 104).

The wireless access point can be configured using a web browser.

Setup using a web browser

Your browser must support JavaScript. The configuration program has been tested on the following browsers:

• Firefox 3.5 or later, Chrome 8 or later, Safari 5 or later
• Internet Explorer 8 or later

Setup Procedure

Make sure device is powered on before you continue setup. If LED light is off, check that AC power adapter, or PoE cable, is properly connected on both ends.

Access device's browser-based setup:

1. Use the included cable to connect the access point to your network via a network switch or router.
2. Open a web browser on a computer connected to your network. Enter the IP address of your access point. By factory default, the IP address will be assigned by a DHCP server (usually the network router). If there is no DHCP server on your network, the default IP address is 192.168.1.252/255.255.255.0.

Note—Use a computer hardwired to the same network as your access point for browser-based setup access. Access to browser-based setup via Wi-Fi is disabled by default.

1. Type in default username: "admin", and password: "admin".
2. Click Log in to launch the browser-based setup and follow the on-screen instructions

If you can't connect:

It is likely that your PC's IP address is incompatible with the wireless access point's IP address. This can happen if your LAN does not have a DHCP Server. If there is no DHCP server in your network, the access point will fall back to its default IP address: 192.168.1.252, with a network mask of 255.255.255.0.

Or, if your PC's IP address is not compatible with this, you must change your PC's IP address to an unused value in the range 192.168.1.1 ~ 192.168.1.254, with a network mask of 255.255.255.0. See Appendix A - Windows TCP/IP (p. 98) for details for this procedure.

Setup Wizard

If you are setting up the access point as a standalone device, run the Setup Wizard. If the access point will be part of a cluster - master or slave - go to Configuration > Cluster > Settings & Status page instead.

1. Click the Quick Start tab on the main menu.

1. On the first screen, click Launch...
2. Set the password on the Device Password screen, if desired.

1. Configure the time zone, date and time for the device on System Settings screen.

1. On the IPv4 Address screen configure the IP address of the device (Static or Automatic) then click Next.

1. Set the SSID information on the Wireless Network screen. Click Next. If you want to configure more than four SSIDs, go to Configuration > Wireless > Basic Settings. The access point supports up to eight SSIDs per radio.

1. On the Wireless Security Screen, configure the wireless security settings for the device. Click Next. If you are looking for security options that are not available in the wizard, go to Configuration > Wireless Security page. The access point supports more sophisticated security options there.

1. On the Summary screen, check the data to make sure they are correct and then click Submit to save the changes.

1. Click Finish to leave the wizard.

IGMP/MLD Snooping
IGMP Snooping	IGMP (Internet Group Management Protocol) is a communications protocol used by hosts and adjacent routers on IP networks to establish multicast group memberships. IGMP is an integral part of IP multicast. IGMP snooping streamlines multicast traffic handling by examining (snoopog) IGMP membership report messages from interested hosts, multicast traffic is limited to the subset of ports on which the hosts reside. IGMP snooping is enabled by default in the access point The access point supports IGMPv1, IGMPv2 and IGMPv3 in IGMP Snooping.
MLD Snooping	MLD (Multicast Listener Discovery) is a component of the Internet Protocol Version 6 (IPv6) suite. MLD is used by IPv6 routers for discovering multicast listeners on a directly attached link, much like IGMP is used in IPv4. Multicast Listener Discovery (MLD) Snooping provides multicast containment by forwarding traffic only to those clients that have MLD receivers for a specific multicast group (destination address). The access point maintains the MLD group membership information by processing MLD reports and generating messages so traffic can be forwarded to ports receiving MLD reports. MLD snooping is enabled by default in the access point The access point supports MLDv1 and MLDv2 in MLD Snooping.

• Disabled - No security. Anyone using the correct SSID can connect to your network.
• WEP - The 802.11b standard. Data is encrypted before transmission, but the encryption system is not very strong.
• WPA2-Personal - This is a further development of WPA-PSK, and offers even greater security, using the AES (Advanced Encryption Standard) method.
• WPA/WPA2-Personal - This method, sometimes called Mixed Mode, allows clients to use either WPA-Personal (with TKIP) or WPA2-Personal (with AES).
• WPA2-Enterprise - Requires a RADIUS Server on your LAN to provide the client authentication according to the 802.1x standard. Data transmissions are encrypted using the WPA2 standard.

If this option is selected:

• This access point must have a client login on the RADIUS Server.
  Each user must authenticate on the RADIUS Server. This is usually done using digital certificates.

Each user's wireless client must support 802.1x and provide the RADIUS authentication data when required.
- All data transmission is encrypted using the WPA2 AES standard. Keys are automatically generated, so no key input is required.

• WPA/WPA2-Enterprise - This method, sometimes called Mixed Mode, allows clients to use either WPA-Enterprise (with TKIP) or WPA2-Enterprise (with AES).
• RADIUS - RADIUS mode utilizes RADIUS server for authentication and dynamic WEP key generation for data encryption.

Priority	Select the priority level from the list. VLAN must be enabled in order to set priority. The 802.1p will be included in the VLAN header of the packets which are received from theSSID and sent from Ethernet or WDS interface.
WMM	Enable or disable WMM. WMM (Wi-Fi Multimedia) is a component of the IEEE 802.11e wireless LAN standard for QoS. WMM provides prioritization of wireless data packets from different applications based on four access categories: voice, video, best effort, and background. For an application to receive the benefits of WMM QoS, both it and the client running that application have to have WMM enabled. Legacy applications that do not support WMM and applications that do not require QoS, are assigned to the best effort category, which receives a lower priority than voice and video. WMM is enabled by default.

WDS

Go to Configuration > Wireless > WDS (Wireless Distribution System) to expand a wireless network through multiple access points instead of linking them with a wired backbone.

WDS only works and interacts with LAPN300, LAPN600, LAPAC1200 or LAPAC1750 devices.

The access point can act as WDS Root or WDS Station:

• WDS Root - Receives WDS connections from remote WDS Stations.
• WDS Station - Connects to remote WDS Root. Supports up to 4 WDS Stations on each wireless radio.

Spanning Tree (recommended if you configure WDS connections)

Before configuring a WDS Station, be sure the following settings of the device are identical to the WDS Root that will be connected. • Radio • IEEE 802.11 Mode • Channel Bandwidth • Channel Note--It is highly recommended that static channel is configured on both APs. Do not use Auto channel option when you enable WDS, as both APs in a WDS link must be on the same radio channel. If Auto option is configured, there is chance two access points run on different channels and WDS link cannot establish. Workgroup Bridge and WDS will not work at the same time on one wireless radio. When Workgroup Bridge is enabled, WDS will be disabled automatically on the same radio.
Remote SSID	Enter the name of the Root's SSID. Click Site Survey button and choose from the list. You must do this for WDS Station to connect to a remote WDS Root.
Remote MAC Address	MAC address of the access point on the other end of the WDS link. Optional WDS Station connects to remote WDS Root by matching SSIDs. When there is more than one remote WDS Root with the same SSID, the WDS Station can differentiate them by MAC address. The format is xx:xx:xx:xx:xx:xx.
VLAN List	Enter the list of VLANs that are accepted by the WDS Station. When VLAN is enabled, the WDS Station forwards to the remote WDS Root only packets in the VLAN list. Packets not in the VLAN list cannot be forwarded to the remote WDS Root. The VLAN List is only applicable when VLAN is enabled. The VLAN list includes 1 to 8 VLAN IDs separated by "", such as "100,200,300,400,500,600,700,800".

Advanced Settings

Go to Configuration > Wireless > Workgroup Bridge to configure advanced parameters of wireless radios.

Band Steering
Band Steering	Enable or disable Band Steering function. Band Steering is a technology that detects whether the wireless client is dual-band capable. If it is, band steering pushes the client to connect to the less-congested 5 GHz network. It does this by actively blocking the client's attempts to connect with the 2.4GHz network.
Isolation
Isolation between SSIDs	Define whether to isolate traffic between SSIDs. If enabled, wireless clients in different SSIDs cannot communicate with each other. Enabled by default.
Advanced Parameters
Wireless Radio	Select the desired radio from the list. Radio 1 is for 2.4 GHz, and Radio 2 is for 5 GHz.
Worldwide Mode (802.11d)	Worldwide Mode (802.11d) enables the access point to direct connected wireless devices to radio settings specific to where in the world the devices are in use.
Channel Bandwidth	Select the designed channel bandwidth for the wireless radio. 20MHz - Select if you are not using any 802.11n wireless devices. 20/40MHz - Select if you are using both 802.11n and non-802.11n wireless devices. 20/40/80MHz - Select if you are using 802.11ac, 802.11n and non-802.11n wireless devices.
Guard Interval	Select the guard interval manually for Wireless-N connections. The two options are Short (400 nanoseconds) and Long (800 nanoseconds). The default is Auto.
CTS Protection Mode	CTS (Clear-To-Send) Protection Mode boosts the access point's ability to catch all Wireless-G transmissions, but it severely decreases performance. By default, CTS Protection Mode is disabled, but the access point will automatically enable this feature when Wireless-G devices are not able to transmit to the access point in an environment with heavy 802.11b traffic.
Beacon Interval	The access point transmits beacon frames at regular intervals to announce the existence of the wireless network. Enter the interval between the transmissions of beacon frames. The value range is between 40 and 1000 milliseconds and default is 100 milliseconds.
DTIM Interval	Enter the Delivery Traffic Information Map (DTIM) period, an integer from 1 to 255 beacons. The default is 1 beacon.The DTIM message is an element included in some beacon frames. It indicates which client stations, currently sleeping in low-power mode, have data buffered on the access point awaiting pickup.The DTIM period that you specify indicates how often the clients served by this WAP device should check for buffered data still on the access point awaiting pickup.For example, if you enter 1, clients check for buffered data on the access point at every beacon. If you enter 10, clients check on every 10th beacon.
RTS Threshold	Enter the Request to Send (RTS) Threshold value, an integer from 1 to 2347. The default is 2347 octets. The RTS threshold indicates the number of octets in a Medium Access Control Protocol Data Unit (MPDU) below which an RTS/CTS handshake is not performed. Changing the RTS threshold can help control traffic flow through the access point, especially one with a lot of clients. If you specify a low threshold value, RTS packets are sent more frequently, which consumes more bandwidth and reduces the throughput of the packet. However, sending more RTS packets can help the network recover from interference or collisions that might occur on a busy network, or on a network experiencing electromagnetic interference.
Fragmentation Threshold	Enter the fragmentation threshold, an integer from 256 to 2346. The default is 2346. The fragmentation threshold is a way of limiting the size of packets (frames) transmitted over the network. If a packet exceeds the fragmentation threshold you set, the fragmentation function is activated and the packet is sent as multiple 802.11 frames. If the packet being transmitted is equal to or less than the threshold, fragmentation is not used. Setting the threshold to the largest value (2,346 bytes, which is the default) effectively disables fragmentation. Fragmentation involves more overhead because of the extra work of dividing up and reassembling of frames it requires, and because it increases message traffic on the network. However, fragmentation can help improve network performance and reliability if properly configured.
Output Power	Select the output power of the access point. If many access points exist, lower power can reduce the signal interference among them.

Captive Portal

Cluster

The cluster function provides a centralized method to administer and control wireless services across multiple devices. When access points are clustered, you can view, deploy, configure, and secure the wireless network as a single entity.

Note- Firmware version 1.1.0 or above support cluster feature. If your device has legacy firmware installed, download the latest one from www.linksys.com/support.

The access points within a cluster must have the same management VLAN configured. A cluster can support 16 LAPAC1750 access points as long as they are same model number.

In each cluster, one access point must be manually configured as the master access point. There can only be one master in a cluster. This master will propagate configuration information, such as wireless settings, time settings etc. to the other team members within a cluster. Log in to the master access point to change sharable parameter settings instead of slaves.

When firmware is upgraded on the master, all slaves within the same cluster will receive the upgrade.

Clustered access points share these configurations:

• User Accounts
  Time Settings
• Log Settings
  Management Access
  Discovery Settings
  IGMP/MLD Snooping
• Wireless Network Mode

Master

Status	Disabled—Cluster function is disabled. Active—Cluster function is enabled and master is active. Active (Backup Master)—Cluster function is enabled and backup master is active. Inactive (Cannot reach the master)—Cluster function is enabled but it's inactive because device cannot reach the master.
Member Number	Number of the members active in the cluster. If an access point joins the cluster but is powered off or cannot reach the master, it is not counted.
Location (Optional)	Where the access point is physically located; for example, Reception. Length is from 0 to 32 bytes.
Cluster Name	Name of the cluster for the LAP device to join; for example, “lab cluster”. All access points with the same cluster name belong to the same cluster. Length of this value is from 4 to 32 bytes and special characters are allowed. This is a mandatory field if the cluster function is turned on.
Backup Master	When an access point works as a cluster slave, it can be enabled as a backup master. When master gets offline, it will take the role of master. When the backup master begins to work, it will send advertisements and slaves will send keep-alive and report sessions to it. When shareable settings are modified in it, it will share them to all slaves. When master gets online again, this backup master AP will stop the master function and let original master AP take over master role.

Client Sessions

Go to Configuration > Cluster > Client Sessions to see the status of wireless clients within the cluster.

The session is the period of time in which a user on a client device (station) with a unique MAC address maintains a connection with the wireless network. The session begins when the WLAN client logs on to the network, and the session ends when the WLAN client either logs off intentionally or loses the connection for some other reason.

When one wireless client of Captive Portal roams from one access point to another in the same cluster, it need not re-authenticate.

IP Address	IP address of the access point to which the client connects.
Location	Location of the access point to which the client connects.
SSID	SSID name of the access point to which the client connects.

Channel Management

Go to Configuration > Cluster > Channel Management to manage the channel assignments for access points within a cluster.

When channel management is enabled, the access point automatically assigns radio channels within a cluster. Auto channel assignment reduces mutual interference (or interference with other access points outside of its cluster) and maximizes Wi-Fi bandwidth to help maintain efficient communication over the wireless network.

Auto Channel

Auto Channel	Access point scans available Wi-Fi channels and changes the channel if better network performance is possible. Disabled by default.
Scan Day	Choose the day of the week when Auto Channel scans Wi-Fi channels. You may choose specific days or have the access point scan and select the best channel daily.
Scan Time	Choose the time of day when Auto Channel performs scan.
Scan Trigger	Because Auto Channel will change the channel if it finds a better one, you can choose when to allow a scan. • Immediately - Scan according to the day/time specified. • No Clients - Scan only if no clients are connected to the wireless radio. If there are clients connected, the access point will complete the Auto Channel operation the next scheduled time when no clients are connected.

Current Channels

Type	Member type of the access point. It can be Master, Slave or Backup Master.

Appendix A - Troubleshooting

Overview

This chapter covers some common problems encountered while using the wireless access point, and some possible solutions to them. If you follow the suggested steps and the wireless access point still does not function properly, contact your dealer for further advice.

General Problems

I can't find new access point on my network.

Check the following:

• The wireless access point is properly installed, LAN connections are OK, and it is powered ON. Check the LEDs for system and port status.
• Ensure that your PC and the wireless access point are on the same network segment. (If you don't have a router, this must be the case.)
• You can use the following method to determine the IP address of the wireless access point, and then try to connect using the IP address, instead of the name.

To find the access point's IP address:

1. Open a MS-DOS Prompt or Command Prompt Window.
2. Use the Ping command to ping the wireless access point. Enter "ping" followed by the default name of the wireless access point. Default name is "lap" followed by the last five characters of device MAC address (e.g., ping lap964d6).
3. Check the output of the ping command to determine the IP address of the wireless access point, as shown below.

If your PC uses a fixed (static) IP address, ensure that it is using an IP address that is in the network segment (subset) with the wireless access point. On Windows PCs, you can use Control Panel > Network to check the properties for the TCP/IP protocol.

If there is no DHCP Server found, the wireless access point will roll back to an IP address and mask of 192.168.1.252 and 255.255.255.0.

My PC can't connect to the LAN via the wireless access point.

Check the following:

• The SSID and security settings on the PC match the settings on the access point.
• On the PC, the wireless mode is set to Infrastructure.
• If using the Access Control feature, the PC's name and address is in the Trusted Stations list.
• If using 802.1x mode, ensure the PC's 802.1x software is configured correctly. See Appendix C (p. 106) for details of setup for the Windows XP 802.1x client. If using a different client, refer to the vendor's documentation.

Appendix B - About Wireless LANs

Overview

Wireless networks have their own terms and jargon. You must understand many of these terms in order to configure and operate a wireless LAN.

Wireless LAN Terminology

Modes

Wireless LANs can work in either of two (2) modes:

• Ad-hoc
  Infrastructure

Ad-hoc Mode

Ad-hoc Mode does not require an access point or a wired (Ethernet) LAN. Wireless stations, e.g., notebook PCs with wireless cards, communicate directly with each other.

Infrastructure Mode

In Infrastructure Mode, one or more access points are used to connect wireless stations, e.g., notebook PCs with wireless cards, to a wired (Ethernet) LAN. The wireless stations can then access all LAN resources.

Note—Access points can only function in Infrastructure Mode, and can communicate only with wireless stations that are set to Infrastructure Mode.

SSID/ESSID

BSS/SSID

A group of wireless stations and a single access point, all using the same ID (SSID), form a Basic Service Set (BSS).

Using the same SSID is essential. Devices with different SSIDs are unable to communicate with each other.

ESS/ESSID

A group of wireless stations, and multiple access points all using the same ID (ESSID), form an Extended Service Set (ESS).

Different access points within an ESS can use different channels. To reduce interference, it is recommended that adjacent access points use different channels.

As wireless stations are physically moved through the area covered by an ESS, they will automatically change to the access point that has the least interference or best performance.

Channels

• The wireless channel sets the radio frequency used for communication.

• Access points use a fixed channel. You can select the channel used. This allows you to choose a channel that provides the least interference and best performance. For USA and Canada, the following channels are available:

• 2.4GHz:

to 2.462 GHz; 11 channels

• 5GHz:

5.180 to 5.240 GHz; 4 channels
5.745 to 5.825 GHz; 5 channels

• When using multiple access points it is better if adjacent access points use different channels to reduce interference. The recommended channel spacing between adjacent access points is five channels, e.g., use Channels 1 and 6, or 6 and 11.
• In Infrastructure Mode wireless stations normally scan all channels looking for an access point. If more than one access point can be used, the one with the strongest signal is used. (This can only happen within an ESS.)
• If using Ad-hoc Mode (no access point) all wireless stations should be set to use the same channel. However, most wireless stations will still scan all channels to see if there is an existing Ad-hoc group they can join.

WEP

WEP (Wired Equivalent Privacy) is a standard for encrypting data before it is transmitted. This is desirable because it is impossible to prevent snoppers from receiving any data which is transmitted by your wireless stations. If the data is encrypted, it is meaningless unless the receiver can decrypt it.

If WEP is used, the wireless stations and the wireless access point must have the same settings.

WPA-PSK

In WPA-PSK, like WEP, data is encrypted before transmission. WPA is more secure than WEP. The PSK (pre-shared key) must be entered on each wireless station. The 256-bit encryption key is derived from the PSK, and changes frequently.

WPA2-PSK

This is a further development of WPA-PSK, and offers even greater security, using the AES (Advanced Encryption Standard) method of encryption. It should be used if possible.

WPA-Enterprise

This version of WPA requires a RADIUS server on your LAN to provide the client authentication according to the 802.1X standard. Data transmissions are encrypted using the WPA standard. If this option is used:

• The access point must have a client login on the RADIUS server.
  Each user must have a user login on the RADIUS server.
• Each user's wireless client must support 802.1X and provide the login data when required.

All data transmission is encrypted using the WPA standard. Keys are automatically generated, so no key input is required.

WPA2-Enterprise

This version of WPA2 requires a RADIUS server on your LAN to provide the client authentication according to the 802.1X standard. Data transmissions are encrypted using the WPA2 standard. If this option is used:

• The access point must have a client login on the RADIUS server.
  Each user must have a user login on the RADIUS server.
  Each user's wireless client must support 802.1X and provide the login data when required.

All data transmission is encrypted using the WPA2 standard. Keys are automatically generated, so no key input is required.

802.1x

This uses the 802.1X standard for client authentication, and WEP for data encryption. If possible, you should use WPA-Enterprise instead, because WPA encryption is much stronger than WEP encryption.

If this option is used:

• The access point must have a client login on the RADIUS server.
  Each user must have a user login on the RADIUS server.
• Each user's wireless client must support 802.1X and provide the login data when required.
• All data transmission is encrypted using the WEP standard. You only have to select the WEP key size; the WEP key is automatically generated.

Appendix C - PC and Server Configuration

Overview

All wireless stations need to have settings that match the wireless access point. These settings depend on the mode in which the access point is being used.

• If using WEP or WPA2-PSK, it is only necessary to ensure that each wireless station's settings match those of the wireless access point, as described below.
• For 802.1x modes, configuration is much more complex. The RADIUS server must be configured correctly, and setup of each wireless station is also more complex.

Using WEP

For each of the following items, each wireless station must have the same settings as the wireless access point.

Mode	On each PC, the mode must be set to Infrastructure.
SSID (ESSID)	This must match the value used on the wireless access point. The default value is LinksysSMB24G for radio 1 and LinksysSMB5G for radio 2. Note—TheSSID is case sensitive.
Wireless Security	·Each wireless station must be set to use WEP data encryption. ·The key size (64 bit, 128 bit) must be set to match the access point. ·The key values on the PC must match the key values on the access point. Note—One set of WEP keys is supported per radio.

Using WPA2-PSK

For each of the following items, each wireless station must have the same settings as the wireless access point.

Mode	On each PC, the mode must be set to Infrastructure.
SSID (ESSID)	This must match the value used on the wireless access point. The default value is LinksysSMB24G for radio 1 and LinksysSMB5G for radio 2. Note—TheSSID is case sensitive.
Wireless Security	On each client, wireless security must be set to WPA2-PSK. • The pre-shared key entered on the access point must also be entered on each wireless client. • The encryption method (e.g. TKIP, AES) must be set to match the access point.

Using WPA2-Enterprise

This is the most secure and most complex system.

WPA-Enterprise mode provides greater security and centralized management, but it is more complex to configure.

Wireless Station Configuration

For each of the following, wireless stations must have the same settings as the wireless access point.

Mode	On each PC, the mode must be set to Infrastructure.
SSID (ESSID)	This must match the value used on the wireless access point. The default value is LinksysSMB24G for radio 1 and LinksysSMB5G for radio 2. Note—The SSID is case sensitive.
802.1xAuthentication	Each client must obtain a certificate for authentication for the RADIUS server.
802.1xEncryption	Typically, EAP-TLS is used. This is a dynamic key system, so keys do NOT have to be entered on each wireless station. You can also use a static WEP key (EAP-MD5). The wireless access point supports both methods simultaneously.

RADIUS Server Configuration

If using WPA2-Enterprise mode, the RADIUS server on your network must be configured as follows:

It must provide and accept certificates for user authentication.
- There must be a client login for the wireless access point itself.
- The wireless access point will use its default name as its client login name. (However, your RADIUS server may ignore this and use the IP address instead.)
- The Shared Key, set on the Security screen of the access point, must match the Shared Secret value on the RADIUS server.
- Encryption settings must be correct.

802.1x Server Setup (Windows 2000 Server)

802.1x Client Setup on Windows XP

Windows XP ships with a complete 802.1x client implementation. If using Windows 2000, you can install SP3 (Service Pack 3) to gain the same functionality.

If you don't have either of these systems, you must use the 802.1x client software provided with your wireless adapter. Refer to your vendor's documentation for setup instructions.

The following instructions assume:

• You are using Windows XP.
• You are connecting to a Windows 2000 server for authentication.
• You already have a login (UserID and password) on the Windows 2000 server.

Client Certificate Setup

1. Connect to a network that doesn't require port authentication.
2. Start your Web browser. In the address box, enter the IP address of the Windows 2000 Server, followed by "/certsrv", e.g., "http://192.168.0.2/certsrv".
3. You will be prompted for a user name and password. Enter the User name and Password assigned to you by your network administrator, and click OK.

1. On the first screen (below), select Request a certificate, click Next.

1. Select User certificate request and select User Certificate, click Next.

1. Click Submit.

1. A message will be displayed and the certificate will be returned to you. Click Install this certificate.

1. You will receive a confirmation message. Click Yes.

1. Certificate setup is now complete.

802.1x Authentication Setup

1. Select Start > Control Panel > Network Connections.
2. Right-click on the Wireless Network Connection, and select Properties.
3. Select the Authentication tab, and ensure that Enable network access control using IEEE 802.1X is selected, and Smart Card or other Certificate is selected from the EAP type.

Encryption Settings

The encryption settings must match the access point's on the wireless network you wish to join.

• Windows XP will detect any available wireless networks, and allow you to configure each network independently.
• Your network administrator can advise you of the correct settings for each network. 802.1x networks typically use EAP-TLS. This is a dynamic key system, so there is no need to enter key values.

Enabling Encryption

To enable encryption for a wireless network:

1. Click on the Wireless Networks tab.

1. Select the wireless network from the Available networks list, and click Configure.
2. Select and enter the correct values, as advised by your Network Administrator. For example, to use EAP-TLS, you would enable Data encryption, and click the checkbox for the setting The key is provided for me automatically, as shown below.

1. Setup for Windows XP and 802.1x client is now complete.

Using 802.1x Mode (without WPA)

This is very similar to using WPA-Enterprise.

The only difference is that on your client, you must NOT enable the setting The key is provided for me automatically.

Instead, you must enter the WEP key manually, ensuring it matches the WEP key used on the access point.

Note—On some systems, the 64-bit WEP key is shown as 40-bit and the 128-bit WEP key is shown as 104-bit. This difference arises because the key input by the user is 24 bits less than the key size used for encryption.
