That maybe.  The visible difference in behaviour is that when there's
no traffic, the reported rate drops to 1Mbps.  As soon as there's
traffic it jumps to 54Mbps.

So far, I've had instances where it's stopped transmitting or
recieving.  It claims to remain associated, but restarting the wlan
interface fails to reestablish the association and a list scan is
empty.  It only seems to happen when the laptop is running on battery.
