Posted to openwrt-users rather than ath9k-devel as a courtesy to the
devs in case someone on openwrt-users knows the answer.

We are seeing signal levels of ~ -100 dBm and we wonder why?

Does the AR9280 have a self-test diagnostic?

AirOS was reporting ~ 70 dBm - ~ 80 dBm;  Radio Mobile suggests we
should be seeing -68 dBm.

Have these units gone south?

best regards/ldv
