Changing of TX rate is normal.

Try following command and see whether it helps:
ifconfig acx0 ratectl onoe

Try turning on debug for it too:
sysctl net.wlan.0.onoe_ratectl.debug=10

I don't have a box at hand, but the exact sysctl node should be
something similar, set it to 10.

This is abnormal.

This means wrong TX rate is picked up.


Try compile and install wlandebug from tools/tools/wlandebug:
make obj; make depend; make; make install

Then try turning on:
wlandebug -i acx0 +state
wlandebug -i acx0 +xrate

The debug messages may be quite verbose, but please mail it to me or
put it to some place I can fetch.  Thanks.
