My University is using a WPA2 Enterprise network, it has these properties:

Authentication: PEAP (Version 0)
Inner Authentication: MSCHAPv2

Connecting to the wifi is almost impossible all the time. But sometimes it does connect. But only stays connected for 20-30 minutes, and then disconnects.

I'll post the output of nm-tool too, just in case. (While connected to the Home network, it gives no trouble).

When searching the forums, it seemed that this was a common issue, but through hours of searching I couldn't find a solution. If anyone knows of any fix, please let me know.

  • Output of nm-tool follows.

have you tried any alternative such as wicd or connman ? – sagarchalise Sep 14 '11 at 4:58
@yasith - are you sure its an encryption issue - could be an MTU issue as per my answer here?… – fossfreedom Sep 14 '11 at 12:54
@sagarchalise I tried wicd today, didn't seem to work out. It's interesting to note that it always connects when I turn the computer on, when I'm in the wifi zone. – yasith Sep 15 '11 at 3:10
@fossfreedom Thank you for the link. I will try that tomorrow at uni. It's hard to debug the issue, because at uni, I don't have wifi, and at home, I don't have the buggy connection. It would be great if anyone of you can direct me towards how to debug this issue. – yasith Sep 15 '11 at 3:13
I looked into the MTU, and it's already at the auto setting. Here's the output of dmesg – yasith Sep 15 '11 at 12:19
