Any wifi protocol savvy people who can explain this:

iwconfig wlan0
wlan0     IEEE 802.11bgn  ESSID:"Private"
             Mode:Managed  Frequency:2.452 GHz  Access Point:
00:AA:BB:CC:DD:EE
             Bit Rate=18 Mb/s   Tx-Power=27 dBm
             Retry  long limit:7   RTS thr=2346 B   Fragment thr=2346 B

Hi,

Did you set the RTS and frag values shown above? I'm not sure but think
that iwconfig will default these to 'off'. You may want to try setting
them to off to see if it improves things.



John.

That seems to be done by the wpa_supplicant application???
I do not use iwconfig to perform association with the AP.

Hi,

But you can change them on the fly :-)
Just run (as root) 'iwconfig wlan0 rts off frag off' from the command
line. If things don't improve then you can set them back ('iwconfig
wlan0 rts 2346 frag 2346').




John.

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
