I keep pings going on another window just to see when it stops.
It was doing alright (pings going through) and suddenly "stops
working" around following lines in logs:
Nov 12 10:59:51 flymockour-l7 kernel: wlan0: ieee80211_bg_scan: active
scan, ticks 7165936 duration 150
Nov 12 10:59:51 flymockour-l7 kernel: wlan0: [6c:f3:7f:4d:88:47] send
QoS null data frame on channel 1, pwr mgt ena
and then it tries scanning and what not but never recovers.
Funny (read annoying) thing is, its not failing in the same way every
time it disconnects. I do not see the same pattern.
And by "stops working" I see, it still has ip and ssid but "status: no
carrier" in ifconfig.

I am not sure if I follow. Any more clues you can throw based on the logs?
