WiFi wont work but Apple Ethernet Will? I just got back to school today after using Ethernet at home.

The WiFi claims to be connected to my Macbook Pro, but I can't get any internet out of it here after an entire semester of working.

I tried resetting the PRAM. And "-"ing Wifi on the Network Settings.

The Ethernet at the University still works, but I can't stay plugged into the wall once classes start. 

Anybody help?
If I was you I'd visit this web page and properly set up your Mac for access to the new WPA2 Enterprise Wi-Fi network at the University of Alabama, but then that would be cheating.
