Please Note:

WEP is an older wireless encryption protocol. While WEP can be used to safely encrypt wireless transmissions, if you have a Wireless N device such as a laptop with a newer wireless network card, you will not communicate with the router at the optimum speed available. WEP should only be used on a network if you have a dated computer, such as one with an operating system older than Windows XP Service pack 2. These older computers are not capable of associating with an access point that uses newer encryption protocols such as WPA. If you have computers that are all newer than Windows XP Service Pack 2, it is recommended that you set up WPA or WPA2 instead.

This walk through also assumes that the router's default IP address and administration user name and password are at defaults. If you have changed either of these, you will be unable to log into the router using this walk through.

  • First, open Internet Explorer or your preferred Internet browser.
  • Next, you will need to log in to the router. To do this, go to the address bar at the top of the page (the long white bar across the top of the screen which will contain the web address of whatever your home page is) and empty it by backspacing all text out of it.
  • Enter the router's IP address, which is by default set to Then press enter.
  • If everything is otherwise set up correctly, the browser should prompt you for a user name and a password. By default, for Linksys routers, the user name is to be left blank (do not type anything in) and the password is admin. Once you have that entered, press Enter on your keyboard, or click the OK button.
  • If the user name and password are accepted, the browser will load a Linksys Basic Settings page. If the user name and password are not accepted, the user name and password have been changed. If you do not know this information, you will have to reset the router.
  • Click the Wireless tab at the top of the Linksys Basic Settings page.
  • First, make sure that if you have an option for Manual security or Wi-Fi Protected Setup, that it is set to Manual. If it is not, set it to manual, then click Save Settings. Otherwise, continue on.
  • Directly under where you clicked Wireless, you will see a link for Wireless Security. Click this link.
  • This page will show you the security types available on the router. By default, the router will probably be set to Disabled.
  • To configure WEP, select it from the list of security modes.
  • The router will prompt you for a passphrase, you can enter any text here, and hit Generate. The router will create a series of keys beneath the passphrase. Key 1 is going to be the password that you will need to remember. You can also type in any 10 digit combination (containing only the characters: 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E, and F [Spaces and punctuation marks are not acceptable either]) in key 1 to use as a password.
  • Click Save Settings. The router will then reboot. If you are on a laptop, you will need to reconnect to the wireless network during which you will be prompted for the key that was just set up. If the computer is a Windows 7 or Windows Vista based computer, you will have to remove the old network profile¬†before attempting to reconnect to the router, or you will get an error saying The profile saved on this computer does not match the requirements of the network.
  • WEP Security should now be enabled on the router. You will need to enter this key into each wireless computer you add to the network. Wired systems do not require a network key to connect.
