Public bug reported:
I get randomly disconnected from the wifi network. When I watch the
syslog I see a warning that might explain it. The full syslog is
attached in the bugreport but below I've added the important part.
When I disabled and enable my wifi adapter I can connect again.
The security for the wifi accesspoint is WPA2 - Enterprise - AES with PEAP
authentication and MSCHAPv2.
