Windows Vista won't connect to Apple Airport Base Station

[navane]

Help! My roommate is trying to get his laptop connected to the wireless network in the house and it won't connect.

He has an HP laptop running Windows Vista and our wireless network is running on an Apple Extreme Airport Base Station. My other roommates haven't had any problems connecting at all; but this guy does.

His laptop appears to connect to the network; but, it won't further connect to the internet. We tried everything and I googled the internet trying to find helps sites and none of the instructions for Vista match the control panels on his laptop.

Anyone have any ideas?
