Ok. I've modified ath_rate_sample in -9 and -head to actually pay
attention to the "ucastrate" configured entry, so it always selects
that particular rate.
Good luck. :)
Btw: wireless discussion also goes on at freebsd-wirel...@freebsd.org.
I invite you to head over :)

Please post whatever rate control code you write or modify, so we can

Hi,

rate, so when you go back to "any", it will choose 54mbit more often.
I suggest looking at the code in
sys/dev/ath/ath_rate/sample/sample.[ch] and see what's

Hello,
I am doing some throughput measurement for Wifi network. I am using jperf/iperf
to generate traffic (at the transmitter) and measure the throughput (at the
receiver). The transmitter and receiver are running FreeBSD 8.2, using CM9-GP
as the Wifi NIC. We are testing AWGN channel. So, the
