HI,

How to GET signal-signal-strength lower than 20dB?

I was trying this:

{
:local interface "wlan3 (AP_5G)";
/foreach i in=[ /interface wireless reg find] do={
:local SIGNAL [/interface wireless registration-table get $i signal-strength];
:local MAC [/interface wireless registration-table get $i mac-address ];

:if ($SIGNAL < -20) do= {log info "Signal too low: MAC: $MAC SIGNAL: $SIGNAL";};
};

But the problem is that variable SIGNAL is not INTEGER, so the question is how to get signal-strength as a INTEGER or how to convert this variable?

use :tonum command to convert variables

HI,

Thank you for the replay!

It this case resolving this problem by this way is not possible becouse input variable is like this:

:local SIGNAL [:tonum "-48dBm@24Mbps"];
:local test [:tonum $SIGNAL];
:log info "tonum: $test";

So the question is how to get this value as a integer or how to parse this variable and convert to integer :slight_smile:

{:local s "-48dBm@24Mbps"; :put [:pick $s 0 [:find $s "dBm"]]}

:local signal ([/interface wireless registration-table get [/int wireless registration-table find] tx-signal-strength] * -1)

that seems to get me the raw number without the @ sign or dbm …

Hi!

Chupaka Thanks for you reply, this solution is working properly!

I was trying also this solution on MT v4.3:

:local signal ([/interface wireless registration-table get [/int wireless registration-table find] tx-signal-strength] * -1)

but this one is not working
