With one antenna connected, I get about 60-80% signal on my iwm client at a distance of approximately 5m. With two antennas connected, the same client needs to be <1m away from the AP to connect at all, and even then gets about <20%.b hostname.athn0: media autoselect mode 11n mediaopt hostap chan 120 nwid
