Ok, I have search mikrotik forum and also google. I am using 3g with USB Huawei modem on roterOS. Is it possible to read signal level even if I am using ppp over 3g modem? The problem is that I can't believe that such option is not implemented. The routers os 20$ can do that but Router OS cannot. Or I can't realize how to do that.

int ppp-client info PPP
working only when usb modem is not used for data

Please make sure 3G card info-channel uses different channel than data-channel.

@sergejs

Thank You for Your advice.

inter/ ppp-client /set ppp-out info-channel=3
I changed info-channel to 3 an now is everything working fine

/interface ppp-client info ppp-out
interface ppp-client info ppp-out

Hello,
Mine runs this way
[engineer@centre] /interface ppp-client> info

But I have monitored it, yet it is still in GSM compact, how do i make the access technology change to 3G, because 3G is in that area.

The picture is attached in it.
