Connection seems to fluctuate between 12-54mbit, sometimes goes to 1mbit
Changing of TX rate is normal.

and completely stalls. However, sometimes it also  completely stalls on
36 (or any other speed) and I can't ping anything. I initially thought
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.
its the wireless router, so i bought a new one from different
manufacturer but it does the samething.
About 50% of times these messages:

acx0: basic rates: 0x0027
acx0: join BSS/IBSS on channel 11
come up like 7-8 times before it reaches handshake or whatever its doing.
This is abnormal.

and sometimes also messages like acx0: tx failed or something like that
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.
