Brett,

If you are referring to the Radio Transmit Rate in the advanced interface 
setup my understanding of how that works is different than what you 
mentioned here.  Every client and base unit has this setting, and except 
for the NDIS clients the transmit rate stays constant at the value you set 
(with the exception of link-test or other special packets).  Also, this 
setting only affects outgoing packets on that device, but the receiving end 
on those transmissions doesn't need to have as high a rx signal to receive 
a 5.5M packet as it does to receive an 11M packet.  Since noise and low SNR 
are usually a problem at our bases we will turn down the transmit rate on 
the clients only for those that are losing packets for client->base.

I would disagree with your second statement, the base station will transmit 
at whatever rate it is set to (but 11M is not really giving 11M throughput 
when you count overhead and incoming transmissions, etc.)  If you're having 
trouble losing packets to a specific client you might want to try lowering 
their radio tx rate...
