Hi, Ray
Are you using Minstrel rate adaptation? Perhaps you can take a look on
the rate control statistic, see what's tx rate or MCS used to
communicate with your desired station. Just to make sure the rate is
correct. Another thing is that open up multiple parallel streams for
iperf during your test.
