I'm trying to set up my girlfriend's wireless network, and her HP dv4000 is pushing me towards insanity. It will connect to the Linksys AP just fine without any security enabled, but times out with "waiting for the network" or "waiting for an IP address" whenever I enable WEP or WPA. I've tried using a Netgear AP with the same results, when other computers connect to it perfectly. Figuring it was a Windows Zero Config problem, I downloaded the newest intel centrino drivers for my board, and installed the intel connection managing software. Still nothing, and it still connects flawlessly without any security enabled. I'm out of ideas, so maybe someone here might have a clue. WinXP SP2 with all hotfixes and updates.
