wireless client disconnection at specified signal levels

RouterOS Wireless Networking

Hi All!

I have this board

[admin@MikroTik] /system routerboard> print
                ;;; Warning: cpu not running at default frequency
       routerboard: yes
             model: 951Ui-2HnD
          revision: r2
     serial-number: **
     firmware-type: ar9344
  factory-firmware: 6.44
  current-firmware: 6.47.10
  upgrade-firmware: 6.47.10
[admin@MikroTik] /system routerboard>

Issue that I specified signal strength and I expect that when particular client reach specified level of signal for example -75dbm will be disconnected.
But in reality this is not happening. With signal level -75dbm rule works when client tries to connect and it just not able to connect as expected.
But after connection succeed client signal may drop below limits and no disconnection happening.

Here is example output

[admin@MikroTik] /interface wireless> access-list print

I tried to create access-list rule from Winbox and with CLI - same effect.

Could please anybody try to reproduce access list behavior , especially if hapac2 available ??
I already tried same thing with hap ac2 (two pieces) and with Router OS 6.49 . Nothing changes. Wireless Client connects at signal level permitted by access rule and stays connected if signal even below 10-15dbm of permitted level.

I even tried just copy paste

If we modify ACL rules in previous example to:

/interface wireless access-list
add interface=wlan2 signal-range=-55
add authentication=no forwarding=no interface=wlan2 signal-range=-120..-56

Then if signal drops to -56, client will be disconnected.

still no luck

Try disabling default authentication within the wireless interface and enabling authentication on the access-list rule.

/interface wireless set wlan1 default-authentication=no
/interface wireless access-list add interface=wlan1 signal-range=-56..120

Rugx, merci!
Now it works sharp as swiss knife. Check on two different boards including ac2.
I’m bit wonder with logic of access rules working. I expected any access rule values will totally “overwrite” behavior of permitted\forbidden bit it does I would say ‘partly’.
Anyway it is not the point to blame logic as solution is on the top : )
