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,
