Dell Inspiron 6000 (centrino) with intel 2200bg wireless card in it running xp home sp2. I can connect and obtain an ip address via dhcp when security is disabled. The connection works fine. When I set WPA or WPA2 personal on (using either TKIP or AES) then I can get a wireless connection but it fails to assign an ip address via dhcp. at this point it will drop the connection and retry again. It looks like some part of the authentication is failing. I've just tried it with WEP security and it works fine. Has anyone experienced the same problems with WPA on the v5 or is it my intel centrino laptop? I don't have another wireless equipped laptop/pc to try with this router at the moment. Any feedback appreciated!
