[Olsr-users] Anyone with verified 802.11n HT speeds on Ubiquiti M devices in adhoc/mesh mode?

For an update, I believe I was able to get HT modes working in IBSS (aka
adhoc) on two Nanostation M5s.  The Links reported 150Mbit/s connection on
both ends after settling, and throughput measured at 45Mbit/s.

This required patches to iw and compat-wireless on OpenWRT r25206. More info

I would be interested to hear if anyone has been able to specify HT modes in
/etc/config/wireless on OpenWRT, since I was unable.

Note that the link speeds did suggest I was getting multiple chains (i.e.
MIMO) very briefly.  My test environment (indoor room, 20feet separation)
could have been non-ideal.
