Martin Schröder, consolidating the report focus, which WiFi device
specifically works in Precise, the Atheros USB stick, and/or the
internal Broadcom?

Title:
  Wifi disconnects every 10 seconds in WPA/WPA2 enterprise

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  If I connect to my university wifi (WPA/WPA2 enterprise, tunneled TLS,
  MSCHAPv2), after a short while I am disconnected and automatically
  connected again (~2 seconds connected, ~7 seconds disconnected).

  I will attach the output in syslog. At 14:36:30 the connection is
  established the first time. Then at 14:36:53 the interface is
  disconnected and at 14:36:59 connected again. This goes on without
  end.

  Ping shows the above mentioned timings:

  This error only occurs, when I'm "connected" to the university network. At home I don't have any problems.
  I also tried different wifi interfaces, its the same:
