disabling power save would be a nice idea,  to see if this issue disappears.
i got the same issue after a long stress test with some other card, sujith
gave me the idea to see if disabling PS helps
sudo iwconfig wlanX power off
sudo iw dev wlanX set power_save off
also please ensure that you run with your power adapter :) i noticed
PS gets enabled
via wext when we plug out the power adapter
