I have a laptop running window xp pro. It has a built in wireless card from Intel. If I plug the computer directly into the Linksys BEFW11S4 it works. The wireless card is showing an excellent signal and is showing that signal from the correct network SSID. The only problem is that the IP address that it is recieving is different from what Linksys distributes by DHCP......What is the problem..........I also uninstalled SP2.
