My girlfriend's apartment has an Airport Express, configured by her new PB. For some reason, my WinXP laptop with a Linksys WPC54G wireless card cannot connect to the internet. Whether using the Linksys config utility or the Windows one, I can connect to the AE, but not the internet. When I try the WinXP "repair" button, it fails because it says the the AE is not assigning a network address to my computer. My wireless internet works fine at my apartment, and it has worked on this AE network before. Any ideas? I tried searching the forums, but couldn't find anything.
