Using precompiled kernel with this patch as provided by NONAKA Kimihiro at:

The issue seems solved.

I can now see the 5Ghz access point with the correct frequency and channel:

bash-4.3$ sudo ifconfig iwn0 list scan
SSID                              BSSID              CHAN RATE  S:N     INT CAPS

*******5Ghz  e0:3f:49:6a:87:ec   40   54M 149:0    100 EP   WPA WME

I can connect to the access point fine with wpa_gui and I don't even
need to set the channel to 40.

I haven't stress-tested but I think this can be marked as a success. Well done

Is this patch going to be incorporated into upstream kernel any soon?
