RSSI threshold events?

RSSI threshold events?

[Ben Greear]

I'm seeing lots of these events in the 3.7.0+ kernel (and in 3.5 as well).

I *should* be connected to good APs that are only a few feet away.

Either way, maybe we should report the threshold and actual value
that caused the event to make it easier to figure out what the
problem is?

(My program has formatted this output slightly)

2012-12-14 09:47:05.154  1.1:  sta1055 (phy #2): connection quality monitor event: RSSI went below threshold
2012-12-14 09:47:05.156  1.1:  sta1056 (phy #2): connection quality monitor event: RSSI went below threshold
2012-12-14 09:47:05.158  1.1:  sta1057 (phy #2): connection quality monitor event: RSSI went below threshold
2012-12-14 09:47:05.160  1.1:  sta1058 (phy #2): connection quality monitor event: RSSI went below threshold
2012-12-14 09:47:05.163  1.1:  sta1059 (phy #2): connection quality monitor event: RSSI went below threshold
2012-12-14 09:47:05.164  1.1:  sta1060 (phy #2): connection quality monitor event: RSSI went below threshold

Thanks,
Ben

Are you saying you're seeing these events without even having configured
them? They should only happen if you configured a CQM RSSI threshold
(and hysteresis) so you should pretty much know what's going on?

I did not configure anything on purpose, at least...is this something
that would be configured through supplicant?

I suppose the supplicant might use it for roaming, but I have no idea
how/where/...
