Hi Brad,

It still seems to be happening with 3.0.0-11.18. One thing I notice is
that iwconfig shows a pretty high "Tx excessive retries" count.

$ iwconfig 
wlan1     IEEE 802.11abgn  ESSID:"xxx"  
          Mode:Managed  Frequency:2.412 GHz  Access Point: xx:xx:xx:xx:Exxxx   
          Bit Rate=90 Mb/s   Tx-Power=15 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality=51/70  Signal level=-59 dBm  
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:77  Invalid misc:21   Missed beacon:0
