Title:
  [Lenovo x220] Wifi keeps dropping with Intel Centrino Wireless-N 1000
  [Condor Peak]

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Once or twice a day (usually after periods of inactivity) my wireless
  connection drops with:

  wlan0: deauthenticated from 00:8a:ae:da:4f:68 (Reason:
  7=CLASS3_FRAME_FROM_NONASSOC_STA)

  I am stationary in comparison to the access point. This seems similar
  in nature to bug # 1396338, but obviously I'm still experiencing it.
