The driver has no tx rate control support and defaults to 1Mb/s so you 
must explicitly set the tx rate to get any reasonable performance. 
However even when locked to 54M on an 11g channel I never saw tcp 
netperf performance much more than ~15Mb/s with a strong signal.  I 
never saw data corruption but mostly was testing wpa.

In general I wasn't impressed with the device and the driver definitely 
needs work.  Hard to recommend it.
