ah, thanks!

in auto mode, the manual settings may be changed at any time, according to the 
algorithm. if you don't want this to happen, you can echo ani-off, which will 
just stop the automatic mode and keep the last values it used, or echo sens-
high or sens-low which will also stop the auto mode, plus set the min/max 
values.

so you have decent truput with and without ani? that probably means not much 
interference (OFDM and CCK error counters should be low).
