We are working on Ubiquity SR71-E mini-PCIe card (based on Atheros AR9280 chipset) and we are unable to get noise level. We use ath9k driver from compat-wireless-2010-10-05 tarball.
As we can see, noise is always equal to -256: $ watch -n 0 -d cat /proc/net/wireless Inter-| sta-| Quality | Discarded packets | Missed | WE face | tus | link level noise | nwid crypt frag retry misc | beacon | 22 wlan1: 0000 47. -63. -256 0 0 0 0 0 0 wlan2: 0000 0 0 0 0 0 0 0 0 0 mon.wlan2: 0000 0 0 0 0 0 0 0 0 0 So we would like to know if there is a way to get this value or if it is not implemented. In the latter case, how can we estimate signal quality?
