Not sure if you realise, but there's a very similar discussion going
on on the madwifi-devel mailing list at the moment, regarding some new
Atheros 5213 based cards not transmitting at higher than 18Mbit/sec.

Sounds to me like a hardware/HAL problem, i.e. wait for this magickal
new "software release" from Atheros I suppose...

Regards, Dan....
