Thank you Mr Leffler for this explanation. Honestly I did not know
about those tools. Very interesting, useful and some curious (say,
number of associations denied by wlan acl) information, which I
believe I will be able to produce some logs of it with audit support.

But I did not find any "signal" information nor any value which looks like
dBm

RSSI is short for 'relative signal strength indicator', you should look here
for it. It is usefull to invoke it with argument, e. g. 'athstats -', which
gives you repeating lines. Useful for tuning.

417831 switched default/rx antenna
Antenna profile:
[1] tx 31753038 rx 33886147
[2] tx 31594701 rx 33711543

# wlanstats -i ath0
1509703 rx discard 'cuz dup
335650 rx frame ssid mismatch
2314 rx deauthentication
377 rx disassociation
4959 rx discard 'cuz acl policy
1068 tx failed for no node
3 active scans started
142 nodes timed out inactivity

Note that I am acting in hostap mode.


This means just you see no rate in output, but otherwise it is just fine.
