signal strength in monitor mode

[Tsuwei Chen]

Seems to me that the current driver does not report signal strength in
the monitor mode. I wonder if anyone is working on that? Tools like
kismet is currently not able to display signal strength because of
that. I tried to print out the signal_strength in rx_status but I
don't think the value is correct when the driver is set to the monitor
mode.

Is this a known issue? Is there any other way to get the signal strength?

Thanks,
Tsuwei

I think I just solved my problem. The signal strength is indeed there.
I just happened to messed up the order inside the radiotap header.
After I adjust the order properly, I can now make kismet shows the
signal strength.

Now I wonder if anyone can tell me what unit is in the raw
signal_strength. Is it in dB? Also, if I also want kismet to show the
noise level, what should I do? Is it possible to deduct it from
signal_quality_ofdm/cck?

Thanks,
Tsuwei

I am also suffering for getting the signal strength in zd1211's monitor mode.
Can anybody share the solution for this problem ?

Thank you,
