I'm trying to connect my school's WiFi which has WPA-EAP. Everything else can connect to it except my ubuntu machine. I can connect on my HTC ONE X Android, OS X, Windows XP & 7, and iOS devices.
So the problem seems to be about either mine or their certificate. I don't really care if they have a valid certificate or not (I'll deal with that in another way). So if this certificate check can be disabled but I can connect, I'm cool with it.
In their own documentation for connecting, they mentioned no certificate from my side is needed.
I'm having Ubuntu 13.04 64bit on a lenovo E135 laptop and some more info:
alfred-nsh@alFiPad:~/repos$ lspci | grep Network

alfred-nsh@alFiPad:~/repos$ uname -a
Linux alFiPad 3.8.0-19-generic #29-Ubuntu SMP Wed Apr 17 18:16:28 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
I am using the propitiatory driver, but I don't really have problem connecting to other networks.
