Frequently Asked Questions - BEFW11S4 LINKSYS

What information should I ask my Internet Service Provider (ISP) to configure the router?
Ask your ISP what type of connection you use: dynamic IP, static IP, or PPPoE. For dynamic IP, note the hostname and domain if any. For static IP, request the IP address, gateway, and DNS. For PPPoE, request the username and password.
The WAN Link LED on my router is not lit, what should I check?
Check that the Ethernet cable connecting the ADSL modem to the router's WAN port is properly plugged in. Depending on your modem, you may need a straight-through cable (most common) or crossover cable.
I cannot access the configuration interface (192.168.1.1) or the Internet, what should I do?
First check physical connections (LEDs on). Then ensure your PC is configured to obtain an IP address automatically (DHCP). On Windows, open a command prompt and type ipconfig; the IP address should be 192.168.1.100 or similar. If not, press and hold the Reset button on the router for 30 seconds to restore factory defaults, then restart the PC.
How do I disable the Internet connection dialog in Internet Explorer?
In Internet Explorer, go to Tools > Internet Options. Under the Connections tab, check "Never dial a connection." Then click on LAN Settings and uncheck all boxes. Click OK to confirm.
How can I improve the wireless range of the router?
Place the router elevated, away from sources of interference (speakers, microwaves, fluorescent lights). Try changing the wireless channel in the configuration interface: go to the Setup tab, change the channel (try 1, 6, or 11) and click Apply.
How do I configure WEP encryption on the router?
In the router's web interface (192.168.1.1), go to the Setup tab. Enable the wireless function. In the WEP section, select Mandatory. Click on WEP Key Setting. Choose 64-bit or 128-bit. You can generate a key via a Passphrase or enter a hexadecimal key manually. Note the key and click Apply.
How do I configure wireless security in Windows XP?
First generate a WEP key on the router. In Windows XP, open Control Panel > Network and Internet Connections > Network Connections. Double-click the wireless connection, then Properties. Under the Wireless Networks tab, select your network (SSID) and click Properties. Check "Data encryption (WEP enabled)", uncheck other boxes. Enter the exact hexadecimal key (10 digits for 64-bit, 26 for 128-bit). Select hexadecimal format and appropriate length. Confirm and restart the PC.
What does the Power LED on the router mean?
The Power LED lights up when the router is powered on and the power adapter is properly connected. If it doesn't light up, check the power supply.
How do I reset the router to factory defaults?
Press and hold the Reset button on the front of the router for more than 30 seconds. The router will restart with default settings. You will then need to reconfigure the router via the web interface.
Can I configure the router using a wireless connection?
Yes, the router can be configured wirelessly, but this quick start guide describes setup via an Ethernet cable. For wireless configuration, connect to the default wireless network (SSID 'linksys', no encryption) and access the web interface. For more details, visit the Linksys website.

How to configure the wireless connection on the LINKSYS BEFW11S4 router?
Frequently Asked Questions - 29/04/2026
Response Notice-Facile

To configure the wireless connection of your LINKSYS BEFW11S4 router, you first need to access its configuration interface via a web browser. Open a browser on a device connected to the router and enter 192.168.1.1 in the address bar. When the login window appears, leave the username field empty and enter admin (in lowercase) as the password. Click OK to access the administration interface.

Once logged in, go to the Setup tab and locate the Wireless section. You will find several important settings to configure there. First, ensure that the wireless function is enabled by selecting Enable in the Enable/Disable field. This step is mandatory; no wireless function will work without it.

Next, configure your network identifier (SSID). The default SSID is "linksys", but it is highly recommended to replace it with a unique name of your choice, containing a maximum of 32 characters. This name must be the same on all wireless devices you wish to connect to the router. Choose a name that is not too obvious to enhance security. Then, select the appropriate Channel from the provided list. Ensure that all wireless devices on your network use the same channel for optimal compatibility.

Securing your wireless network is essential. After configuring the SSID and channel, click the Apply button to save these basic settings. Then, go to the Wireless Security Configuration section to enable WEP encryption. Select Mandatory in the WEP section and click the WEP Key Setting button to define the type and level of encryption. The BEFW11S4 router supports 64-bit and 128-bit WEP encryption. 128-bit encryption is recommended for better security; generate or enter a key corresponding to the chosen level. Important: all wireless devices connected to the network must use the same level of encryption (64 or 128 bits).

To further enhance security, enable the MAC Address Filtering feature. This function allows you to determine which specific devices can connect to your network by allowing only the MAC addresses of your devices. You will need to enter the MAC address of each network adapter you wish to allow; MAC addresses not included in the list will not have access to the network.

Once all settings are configured (SSID, Channel, WEP, and MAC list), click Apply to save all changes. The router will apply the new settings and may require a restart to fully activate all changes. Restart the router and the client devices configured with the same wireless settings as the router. Your LINKSYS BEFW11S4 wireless network will then be operational and secure.

Introduction

Thank you for choosing the Instant Wireless™ Wireless Access Point Router. This Router will allow you to set up a network with your PCs and even share your Internet connection.

How does the Router do all of this? By connecting your ADSL modem directly to the Router and using the Router's Ethernet ports to connect your PCs, it's almost as if each PC is connected directly to the Internet. In this way, you can have several PCs utilizing one Internet connection simultaneously. Plus, because it's also an Access Point, the Router can bridge your Ethernet network with your wireless PCs.

But what does all of this mean?

Networks are useful tools for sharing computer resources. You can access one printer from different computers and access data located on another computer's hard drive. Networks are even used for playing multiplayer video games. So, networks are not only useful in homes and offices, they can also be fun.

The PCs you connect to the Router's four LAN ports, when properly configured, create a LAN, or Local Area Network. They are connected with an Ethernet cable plugged into your computer's Ethernet adapter at one end and into one of the Router's LAN ports (numbered from one to four) at the other end. The term "Ethernet" is used to refer to your network accessories, such as cables and adapters, because Ethernet refers to the type of network you are setting up. In your Router's documentation, Ethernet refers to accessories that transfer computer data from 10Mbps to 100Mbps. (10Mbps and 100Mbps refer to the speeds used by network devices. When transferring data at 10Mbps, you are moving the equivalent of over seven floppy disks every second! Network accessories that function at 100Mbps move data ten times faster!)

PCs can also interact with the Router wirelessly. By configuring your wireless PCs with the same wireless settings as the Router, you can bridge these wireless PCs while integrating them into your existing Ethernet network.

Perhaps the most remarkable thing the Router does is to allow you to share your ADSL connection. This is done by connecting your ADSL modem to the Router's WAN port with an Ethernet cable. (WAN refers to a Wide Area Network.) The Internet is a network that, being global, covers the widest area of all! The PCs connected to the Router share this connection.

Use the instructions in this Fast Start to help you connect the Router, configure your PCs, and configure the Router in your network. These instructions should be all you need to get you up and running with a basic network, sharing your Internet access. The Router also comes equipped with more advanced functions, but these functions should not be utilized without a further understanding of routers and networks.

This is What You Will Be Setting Up
What You Will Be Setting Up Internet

The Router's setup is similar to that shown in the figure above for any Windows PC. The Router lets you share your ADSL connection among several computers in your home or business. This is called a Local Area Network or LAN.

This Fast Start guide gives you the “big picture” of what you need to set up a basic home or business network. The next three sections explain how you will set up and configure your equipment to enable shared high-speed access to the Internet.

Step 1: Connect the Router

This walks you through the process of connecting the Router to your ADSL modem. Then, it shows you how your PCs are connected to the Router.

Step 2: Configure the PCs

This describes how your PCs are configured to communicate with the Router.

Step 3: Configure the Router

This step walks you through some basic Router settings, making it work with your ADSL modem and your ISP's settings.

LINKSYS BEFW11S4 - Step 3: Configure the Router - 1

Note: This Fast Start Guide will direct you how to set up the Router with Ethernet cables. While the Router can be set up through a wireless connection, details about setting up the Router wirelessly will not be addressed in this Fast Start Guide. Those who wish to set up the Router through their wireless connection should refer to the Linksys website at www.linksys.com.

Step 1: Connect the Router

LINKSYS BEFW11S4 - Step 1: Connect the Router - 1

In Step 1, you will connect the Router to your ADSL modem and to your home or business computers.

First, make sure that all devices you'll be working with are powered down, including your PCs, modem, and the Router.

A. If you haven't already done so, connect your ADSL modem to the phone jack. (Follow the instructions from your ADSL modem's installation guide.)
B. Using an Ethernet cable, connect the LAN or Ethernet port of the ADSL modem to the Router's WAN port.

LINKSYS BEFW11S4 - Step 1: Connect the Router - 2

natural_image Front view of a black wireless router with two antennas and a blue cable inserted (no visible text or symbols)

C. Connect an Ethernet cable to your PC's Ethernet adapter. Connect the other end of the cable to one of the Router's LAN ports. Repeat this process for every PC you wish to connect to the Router.

LINKSYS BEFW11S4 - Step 1: Connect the Router - 3

natural_image Close-up of a white electronic device with an attached blue medical or laboratory probe inserted into the port, showing network ports and green indicator lights (no readable text or symbols)

Note: If your PC's Ethernet adapter is not set up, please refer to the Ethernet adapter's documentation for more information.

For ease of installation, start with LAN Port 1 on the Router, then Port 2, Port 3, and finally Port 4.

LINKSYS BEFW11S4 - Step 1: Connect the Router - 4

natural_image Front view of a wireless router with two antennas and a blue cable inserted (no visible text or symbols)

D. Connect the power adapter to the Router's Power port. Then, connect the power adapter to an electrical outlet. Turn on the ADSL modem. Then turn on the first PC you wish to use when configuring the Router.

Proceed to Step 2: Configure the PCs on the next page.

Step 2: Configure the PCs

LINKSYS BEFW11S4 - Step 2: Configure the PCs - 1

natural_image Illustration of a network device with Internet connection icon, showing router, wireless router, and desktop computer (no text or symbols on devices)

In Step 2, you will configure each of your computers to communicate with the Router.

To do this, you will need to configure your PC's network settings to obtain an IP (or TCP/IP) address automatically. Computers use IP addresses to communicate with each other across a network or the Internet.

Find out which operating system your computer is running, such as Windows 98 SE, Millennium, 2000, or XP. You will need to know which operating system your computer is running. You can find out by clicking the Start button and then selecting the Settings option. (If your Start menu doesn't have a Settings option, you're running Windows XP. You can select the Control Panel directly from the Start Menu.) Then, click Control Panel and double-click the System icon. Click the Cancel button when done.

Once you know which Windows operating system you are running, follow the directions in this step for your computer's operating system. You may need to do this for each computer you are connecting to the Router.

The next few pages tell you, step by step, how to configure your TCP/IP settings based on the type of Windows operating system you are using. Once you've configured your computers, continue to Step 3: Configure the Router.

Securing your wireless network

Using radio waves, a wireless network introduces some security risks which are not present in a wired network; an unauthorized third party can intercept transmitted data, gain access to your wireless network, ... In order to make your wireless network as secure as a wired network you should apply, at least, the following guidelines:

1. Change the SSID

Your wireless network is identified on the basis of an SSID (Service Set Identifier). This parameter, which can be considered as the networkname, is broadcasted periodically through a beacon. Also the SSID is, in most cases, set default to a welknown value. To improve the security you can :

  1. disable the SSID broadcast. Users who want to connect to your wireless network must know this value to become connected. Also, your wireless network becomes invisible to a third party.
  2. change the default value of the SSID. The SSID can contain maximal 32 characters and it's best to choose a value which is not too obvious.

2 Activate WEP

To guarantee that your data is transmitted in a private manner, you should activate WEP (Wired Equivalent Privacy). Use of this protocol will result in your data being encrypted while travelling through the air. Choose the largest encryption key possible (in most cases this is 128 bits) and make sure that each PC on your wireless network uses the same key as the access point. You can even improve the security by changing the WEP-key on a regular base.

3 Activate MAC-address control list

By means of the MAC-address list, also known as the Association Control List, you can determine which client adapters can access your wireless network. This is done by introducing the MAC-address of the client adapter in the concerned list of the access point. A MAC address consists of 12 characters (0-9,A-F) and can be found on the back of the client adapter. A client adapter whose MAC address is not included in the list will not be granted access to your wireless network.

4 Change / activate passwords

Configuration of the access point is done through a web browser. Secure this access, and any other access which may exist, by a carefully chosen password. If a default password, set by the manufacturer, is used, you should replace this by your own password.

The Help section contains the most frequently asked Internet connection questions. If you have additional setup needs or you wish to get information on the Advanced Features, please visit kb.linksys.com

1. I'm not sure what information I need from my Internet Service Provider (ISP) to get my network up and running. What questions should I ask?

What type of connection do I have: dynamic IP address, static IP address, or PPPoE?

• If I am using a dynamic IP address, I should ask:

  • What is my Host Name (if needed)?
  • What is my Domain Name (if needed)?

• If I am using a static IP address, I should ask:

  • What is my IP Address?
  • What is my Gateway?
  • What is my DNS?

• If I am using PPPoE (typically used by ADSL ISPs), I should ask:

  • What is my User Name?
  • What is my Password?

After you obtain the information, follow the instructions in the Fast Start - Step 3: Configure the Router, and use this information to enter on the Setup tab. In the WAN Connection Type section, refer to the chart on the next page:

If you have this type of connection:Perform these steps:

RAS or PPTPIf you are using RAS (Singapore SingTel) or PPTP (service in Europe), check with your ISP for the necessary setup information.
  1. I'm having problems connecting to the Internet, what LEDs should be lit on the front of the Router?

- Each Router's LED will light up for any proper connection made on the back of the Router—whether it is an Ethernet cable or power cord.

For example, the following are typical LEDs that light up once a computer and DSL modem are connected:

  • When the Router is turned on (the power adapter is plugged into the Router), the Power LED lights up.
  • When an Ethernet cable is properly connected between a PC and Port 4 of the Router, the Link/Act, Ful/Col, and 100 LEDs in Column 4 light up.
  • ADSL modem connection causes the WAN Link LED to light up.

• My WAN Link LED isn't lit. What should I check?
- Check that the cable you are using between your ADSL modem and the Router is the same cable that came with your modem. Depending on the type of connection your modem uses, you may need either a "straight-through" or "crossover" Ethernet cable (the "straight-through" type is more common).
- Some of the lights on the front of the Router don't light up when I plug in a PC. - Only the Link/Act LED is required for a connection to work correctly.

  1. I cannot get onto the Internet, nor can I access the Router's Setup page. What should I check?

A. First check that the ADSL modem and computers are properly connected to the Router. See Question #2 for how to verify that the connections are good.
B. Then, check that you have properly configured your PCs to communicate with the Router. Below you will find instructions for the various versions of Windows.

- Windows 98 SE, or ME

  • Click the Start menu, and then click Run. After the Run window appears, enter winipcfg in the Open field, and then click the OK button.
  • When the IP Configuration window appears, click the gray box with a black arrow pointing down.
  • A list of adapters will appear. Select the adapter that you use to connect to the Internet. These items should not contain "PPP", "VPN", "AOL", or "Dial-Up adapter" as part of the entry.
  • The IP Address field should show an IP address of 192.168.1.100 or 192.168.1.xxx, with "xxx" being any number greater than 100. If your IP address is not in that range, hold the reset button on the front of the Router for more than 30 seconds. This will cause your Router to be set to factory default, so you will need to re-configure the Router's Setup page. After re-configuring the Setup page, restart the computer.

- Windows NT, 2000, and XP

  • Click the Start menu, and then click Run. After the Run window appears, enter cmd in the Open field, and then click the OK button.
  • This will open a command prompt. Enter ipconfig /all and then press the Enter key.

- The IP Address field should show an IP address of 192.168.1.100 or 192.168.1.xxx, with "xxx" being any number greater than 100. If your IP address is not in that range, hold the reset button on the front of the Router for more than 30 seconds. This will cause your Router to be set to factory default, so you will need to re-configure the Router's Setup page. After re-configuring the Setup page, restart the computer.

C. Now you will configure some settings in Windows.

  • Go to your desktop and double-click My Computer, and then double-click Control Panel (Windows XP users using the default interface, click Start, and then select Control Panel).
  • When the Control Panel window pops up, double-click the Internet Options icon (Windows XP users using the default interface, click Network and Internet Connections, and then click Internet Options).

  • Check Never Dial Up a Connection. (If this choice is grayed out, that is fine.)
  • Click the LAN Settings ... button in the lower right-hand corner.
  • When the Local Area Network (LAN) Settings window appears, uncheck all boxes.
  • Click the OK button and the Apply button (the Apply button will be grayed out if you did not have to make any changes). Then click the OK button again.
  • Exit the Control Panel, and restart your computer.

  • When I click on the icon to access the Internet, and enter the user name and password that my ISP gave me, I cannot connect to the Internet. What is wrong?

This means that you're using the software given to you by your ISP. Please use Internet Explorer or Netscape Navigator, which is located on your desktop (located on the Start Menu in Windows XP).

  1. When I use Internet Explorer, a box pops up prompting me to dial up a connection. How can I disable that?

A. Go to your desktop and double-click My Computer, and then double-click Control Panel (Windows XP users using the default interface, click Start, and then select Control Panel).
B. When the Control Panel window pops up, double-click the Internet Options icon (Windows XP users using the default interface, click Network and Internet Connections, and then click Internet Options).
C. When the Internet Options window appears, click the Connections tab.

D. Check Never Dial Up a Connection.
E. Click the Apply button.

6. I get no signal strength or link quality or signal strength, what can I do?
A. Verify that the Router's WLAN LED is illuminated.
B. Verify that all of your wireless PCs are using "Infrastructure" mode.
7. How can I improve the Router's range?
A. Verify that the Router is as high off of the ground as possible.
B. Verify that there are no large sources of electrical interference nearby. (For example: speakers breaker boxes, florescent lights, microwaves, etc.)
C. Change the wireless channel being used. To do this:
- Open your web browser and type http://192.168.1.1 into the "Address" field.
- In the "Enter Network Password" box, leave the "User Name" field blank and type admin as the password. Then, click OK.
- From the Setup tab, change the channel to 1.
- Click the Apply button to save the settings.
- Continue doing this until you find the channel that provides the best range.

Configuring Wireless Security

LINKSYS BEFW11S4 - Configuring Wireless Security - 1

Note: WEP encryption is an additional data security measure and not essential for router operation.

An acronym for Wired Equivalent Privacy, WEP is an encryption method used to protect your wireless data communications. WEP uses a combination of 64-bit or 128-bit keys to provide access control to your network and encryption security for every data transmission. To decode a data transmission, each point in a network must use an identical 64-bit or 128-bit key. Higher encryption levels mean higher levels of security, but due to the complexity of the encryption, they may mean decreased network performance.

You may also have heard the term “40-bit” used in conjunction with WEP encryption. This is simply another term for 64-bit WEP encryption. This level of WEP encryption has been called 40-bit because it uses a 40-bit secret key along with a 24-bit Initialization Vector (40 + 24 = 64) . Wireless vendors may use either name. Linksys uses the term “64-bit” when referring to this level of encryption.

Make sure your wireless network is functioning before attempting to configure WEP encryption.

A 128-bit WEP encrypted wireless network will NOT communicate with a 64-bit WEP encrypted wireless network. Therefore, make sure that all of your wireless devices are using the same encryption level. All wireless devices complying with the 802.11b standard will support 64-bit WEP.

In addition to enabling WEP, Linksys also recommends the following security implementations:

  • Changing the SSID from the default “linksys”
  • Changing the WEP key regularly

LINKSYS BEFW11S4 - Configuring Wireless Security - 2

Note: In order for WEP Encryption to be enabled, wireless functions must first be enabled. Select Enable on the Router's Wireless tab before proceeding.

The following steps will show you how to utilize WEP encryption

  1. From the Web-based Utility's Setup tab, select Mandatory under the WEP section.
  2. Press the WEP Key Setting button to set the WEP Encryption type and level.
  3. The screen displayed in Figure C-1 may appear, verifying that you are enabling WEP Encryption. Press the OK button to continue.
  4. This will display the screen shown in Figure C-2. From this screen, you will choose your WEP Encryption settings.

Microsoft Internet Explorer Do you want change WEP status to Mandatory? OK Cancel

- WEP (64Bit or 128B) Select the level of encryption from the drop-down box. 128-bit WEP encryption is unique to Linksys and may conflict with other vendors' WEP encryption.

LINKSYS BEFW11S4 - Configuring Wireless Security - 5

Note: In order to utilize WEP encryption, all points in your wireless network must have WEP enabled and be set to the same Key Setting.

The WEP Encryption key is generated in one of two ways:

  1. You may create an encryption key by using a Passphrase.

a. Enter a Passphrase, a user-defined password, into the Passphrase field. The Passphrase can be a maximum of 31 letters, symbols, and numbers. No spaces can be used.
b. Click the Generate button to create a key. The key will be 10 digits if you chose 64-bit encryption, or 26 digits if you chose 128-bit encryption. This key will be used to encrypt and decrypt the data being sent between the Router and your network's wireless PCs.

The Key field may not display all digits. Using the mouse, click anywhere within the Key field. Move the cursor to the right to view the rest of the Key. Make sure your write down the entire Key EXACTLY the way it is displayed.

  1. You may enter the encryption key manually.

Make a note of the Passphrase or Manual Key. You will need it for the other wireless devices on the network, as the same WEP encryption key must be entered in all wireless devices on the network.

Once you have chosen your key encryption method and entered either the Passphrase or manual key, click the Apply button, and the encryption portion of the setup is complete.

LINKSYS BEFW11S4 - Configuring Wireless Security - 6

Note: In Windows XP, a 128-bit Key generated by the Router will be called a "104 bits (26 digits)" key, and a 64-bit Key generated by the Router will be called a "40 bits (10 digits)" key.

Configuring Wireless Security in Windows XP

As Windows XP does not allow for the use of the Linksys Passphrase feature with the wireless PC adapters, you will need to manually enter the key generated in the previous section.

The following steps will help you enable WEP and enter the encryption key manually for your wireless PC cards, in order to enable your Windows XP system to communicate with the Router wirelessly.

These steps assume that your CD-ROM drive is letter D and that you are running Windows XP in the default mode.

Be sure you have the WEP Key generated by the Router.
