Can you retry with mistrel? In my experience, it converges to a lower rate than
does pid, but it doesn't fluctuate as much.
I'll look into RT2561.
What I generally do is start a ping in one window and enter the following line
in another:
while [ 1 ] ; do iwconfig wlan0 | grep Mb ; sleep 1 ; done
and watch the rate.
