You must enter the encryption keys − including specifying the default key − exactly 
as you entered them into your Access Point. If you have any difficultly making a 
connection between your C54RU and your Access Point, disable WEP and verify that 
the connection can be made without any encryption. Then re-enter the WEP keys 
into your Access Point and your C54RU such that they are exactly the same.

Setting the IP Address and Proxy Server Setting the IP Address and Proxy Server 
The C54RU’s WLAN Utility allows you to make IP address and proxy server settings 
for each of the WLAN links you want to connect to. This allows you to have 
multiple IP address and proxy server settings for multiple WLAN Access Points. For 
example, if you have an Wireless Access Point at work, you will need one set of IP 
address and proxy server settings to connect to your companies LAN. If you also 
have a Wireless Access Point at home, you will need a different set of settings to 
connect to that Access Point. For each of the WLAN links that are listed in the 
Preferred WLANs field of the Configuration page, you can enter a different set of IP 
address and proxy server settings. Each time that link is established, the settings 
saved for use with that link will become active.
