I have the same problem, but am able to provide some more information.
1. I'm unsure if the phase2 authentication (MSCHAPV2) is saved correctly. When i edit the connection again, it is set to "None", but i when i edited the connection with wifi advanced configuration editor (app), it wás set to MSCHAPV2.
2. My Android 2.3.4 EVO 3d connects without any problems.
3. It gets stuck in a loop of scanning, connecting, disconnected. So the problem should be in authentication.
I've read a couple of threads outside of XDA, but none of their solutions work..
