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.

I've tried suggestions from these links, all to no avail:
