Mohammed,
Thanks very much for the response.
Yes I get "Operation not supported":
# iwconfig wlan0 modu 11b
Error for wireless request "Set Modulation" (8B2F) :
SET failed on device wlan0 ; Operation not supported.
...so what does this mean; what are my options here? In view of
the fact that the capability of changing modes (from 'g' to 'b'
...etc.) is an essential requirement, am I using the wrong driver
...is there a different driver that supports this chip? Or is it that
there's no driver that supports this chip so that I would have to put
this functionality into ath9k myself if I want it?
Adding that functionality should not be necessary. The simple command
iw dev $WIFIDEV set bitrates legacy-2.4 1 2 5.5 11
will restrict the device to 802.11b rates, which I think is what you want. This
command does not involve the device driver, but sets the appropriate parameters
in mac80211.
