Hi, I spent some time trying to setup a WPA authentication between a D-Link 624 router and a laptop running Windows XP, with an built-in Intel 2200BG wireless adapter.
The wireless worked fine without encryption. With WPA there was the message "limited or no connectivity", though the signal was excellent. I couldn't ping the router. As ipconfig reported an IP address of 0.0.0.0, I tried to assign a fixed IP address to the laptop, and to my surprise the connection worked with WPA.
Anybody has encountered that already? Thanks.
