I don't think the noise stats that the AP on WLAN 2 sees are meaningful
unless there's a lot of traffic going over both networks.
Signal and noise levels in STA mode are given in dBm with this driver I
think. Unfortunately the levels in AP mode are in some unknown (to me)
unit from the firmware. AP mode also doesn't seem to generate a link
quality for its STAs, but you can simulate it pretty easily with a
signal:noise ratio on a logarithmic scale (or so I've found).
