I've recently installed the latest version of Ubuntu (64 bit), alongside my Windows 8 dual booted machine. The problem I'm having is trying to connect to my school network, the school uses a username and password system, so upon entering them the top right corner icon attempts to connect to to the network, but after some amount of time either disconnects, or tells me to enter the details again.
On another note, my computer appears to work fine wireless wise when I'm at home (Which only requires password entry and not a username to get on the network). Also, I know this problem has nothing to do with my schools internet because I'm using it at this moment, on Windows 8.
I've tried suggestions from these links, all to no avail:

Had a similar issue. In case it is helpful for anyone, for me it was just a matter of changing from TLS to PEAP under the network settings.
