Comment 3 for bug 837076

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
