Wireless failure

[splendiferous]

My MacBook's wireless has failed at the University of Texas at Austin. They have this system in which you need to connect to a "guest" service and then set up a "restricted" service if you are a student. After a few months, the wireless just completely shut down. When I try to rejoin the server, it keeps saying that it cannot find an IP address. The ethernet still works, thankfully.

However, I found that the wireless will work XP via Boot Camp, but not through Leopard. The IT squad here is baffled. Any ideas on how to fix this? I don't really like using Windows for anything other than gaming.

Try going to Network Preference, under Airport, click Advanced... Now delete your University Connection under 'Preferred Networks'. OK then Apply.

See if you can reconnect from scratch.
(Just a suggestion, it may or may not work)

I've tried that. Every time I try to connect to the network from scratch again, it can't find an IP address, so it auto-assigns me an IP, which obviously doesn't work.
