If the access points are very close together, you might also try
turning down TX power on both ends.
What is the dBm reported by iw station dump at each end? Anything
below 60dBm might indicate the radios are talking way too loud.
While they were sitting at -40 for a little while I turned the tx power
on both sides way down to achieve about -62. I also have RF terminators
I have tried with that bring it down into the -70's at close range.
Each scenario seems to produce the same result.
I seem to have an excessive amount of tx retries as well, I wonder if
that has something to do with it? Which makes me think it's more of a
hardware issue. I don't know.
Thanks (and sorry for the company footer, I can't turn it off)

Hello,
I've just spent the last few hours reading many threads in the
archives from this list. I'm hoping someone may be able to help
me, else I think I have a batch of bad radios.
Summary: hardware is two identical routerstation pros running
OpenWRT bleeding edge from 2012-03-14 (with a compat-wireless from
february I believe). SR71-A (ath9k) radio in each.
I'm bringing up the interfaces in each like this:
iw phy0 interface add wlan0 type mp
iw phy0 set channel 36 HT40+
iw wlan0 set meshid TheMeshID
ifconfig wlan0 up
brctl addif br-lan wlan0
Running iperf in either direction produces a range of 13-16
Mbits/sec when I can point to countless examples in the mailing
list archives that show people getting significantly higher bandwidth.
While pushing my test through, an `iw dev wlan0 station dump` on
either node often shows the bitrates at:
300.0 MBit/s MCS 15 40Mhz short GI
I'm getting similar, if not poorer results on higher 5ghz channels
(149+, 157+). Am I horribly misconfiguring something or is it my
hardware? My antennas are 3x3 panels spaced about 10 meters apart.
Thanks for any insight,
