Hi!

Did you test this in 11abg mode? Or just 11n?

I've got a 3x3 AR9160 card which I'm considering disabling radio
chains on to compare performance. This seems like it's a useful thing.

Whilst talking about antennas, do you/anyone know how TX/RX antenna
setting/diversity works on the AR9160/AR9106 in 11abg mode(s) ? I've
been investigating it with a spectrum analyser for the TX path but I'm
curious about the specifics on how both TX/RX radios and antennas
works in the non-n modes.

Thanks,


Adrian
