so heres some backstory to this problem. I have a 3GS jailbroken 3.0.1. i have a router at home and I connect just fine via wifi. I also go to college. My college has a campus-wide wifi network. It does not use a network password, but once u try to use the web it will redirect you to a school login page where you put in student info, but the network
itself is not passworded. Anyway it has worked great forever but in the last few days i cant connect to my school wifi! its so annoying. It shows up in available networks list, and when i choose it it doesnt connect, but it doesnt say "unable to join" or any type of message. The annoying thing is my girlfriends 2G iphone running 3.0.1 can connect to the school wifi just fine, so can my Macbook, and other friends' iPhones... what could be the problem?
