Public bug reported:
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.
