Hi John,
The link quality (signal strength) came back up
after a few  minutes, but bit rate remains fixed.

           Bit Rate=18 Mb/s   Tx-Power=20 dBm
           Retry  long limit:7   RTS thr:off   Fragment thr:off
           Power Management:off
           Link Quality=70/70  Signal level=-30 dBm
           Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
           Tx excessive retries:0  Invalid misc:50   Missed beacon
