comment:
:Step to reproduce this bug:
:1/ Connect to a WPA2 Entreprise Wifi (PEAP, MSCHAPv2).
:2/ Wait until the bug appears (quite short).
:3/ Often the connection doesn't work after the bug occurs (doesn't pass the "waiting for authorisation" state), the only way is to reboot. Sometimes, the connection is still up, but there is no reception according to the network manager (under KDE).
:
:The bug can be reproduce. I am using a Thinkpad X201, the wifi card is Intel Centrino Advanced-N 6200, driver iwlagn.
