Video streaming? Does your application use QoS AC_VI(deo) for streaming,
or just bulk data (AC_BE(st effort))?

Reason 7 is: [AP received a] class 3 (data) frame from non-associated STA.
This can happen when your are "actively" disassociating from the AP (unlikely),
when the AP thinks you are out-of-reach(unlikely, since your signal seems to
be strong and PSM isn't enabled by default) or when the AP crashes and resets.
You should check your AP's TSF. (iw dev wlanX scan).
It should not go backwards.
(But if it does, then it might be because carl9170 has accidentally DoSed it?!)

Christian
