I have changed my router encryption from WAP to WEP (need WEP to connect to Xbox 360 game adapter). I have changed the router settings, given it a new network name and wep password. When I try and connect a laptop to the new network, using the new details, it cannot aquire an ip address. The laptop connected ok to original sky WAP network).

Not sure if i have missed something but any advice would be appreciated.

I am running XP on bot my desk top and laptop. My desktop is connected directly to the router via cable supplied.
