3G Modem - Signal Strength?

Thu Apr 26, 2012 6:52 pm

Hi guys,

Is there any way to see the signal strength of my 2g/3g connection while ppp is running?

I'm currently on the other side of the globe and the router is having some performance issues but I can't see any signal strength without shutting down the PPP-client.

I can get it using this command on my MT:

/interface ppp-client info <3G modem interface>

Are you sure that you can do it while the PPP-client is using the modem?

What version of ROS are you using?

The modem is a ZTE MF626 on 5.14 and I tested the command while the PPP session was up.

You can also see this in Winbox :

-> open winbox
-> left-click "PPP"
-> left-click "Interface" tab ( default )
-> double-left-click on your 3G modem interface
-> left-click on "Info..." in right menu, almost on the bottom
-> make sure that in the "interface" option on the popup window your 3G connection is selected
-> "Signal Strength" at the bottom of the list will display your current 3G signal strength

Some general info about dBm ( in case anyone finds this post and won't know what to do with the actual values )
A 3G signal strength between -70 dBm and -80 dBm is optimal, but sometimes even on -100 or even -110 (worse) you can still get decent internet.

Lower dBm values means better 3G connection.

@ poxx
Thanks for this great info about "dBm"! I found this "info" button, but RouterOS says - "Modem couldn't respond". Data Channel was "0", Info Channel was "1". But when I changed Info Channel to "3", info shows up! Modem type: Huawei E353, working great with ROS 5.19.
