   the following:

1. Turn Wireless ON
   Wireless: On

   To change the channel of the frequency band at which the Router 
   communicates, please select it below ('Auto' scans channels 1, 
   6 & 11 and picks the cleanest channel). Then click apply to save 
   your settings.

   WEP: On
 
5. Select a WEP Key
   Note:To create a 64-bit WEP Key, you need to enter a combination of 
   10 digits. You can choose any letter from A-F, a-f or any number

7. Write down wireless settings.
   In order for every computer to connect to this Router wirelessly, 
   you need to make sure that the wireless setup for each computer uses 
   the SAME settings listed below. Please make sure that you write down 
   all of the values set on this screen.

The most important thing is to turn on the wireless service, turn WEP to protect the wireless access, and remember the SSID and the key code.
