Hello!
Router RB750UP (6.19 v) with Huawei E3372.
Modem E3372 determined like lte1 interface. Internet work. Modem work.

Modem detected in Resources ---> USB, but not get port. System--->Ports is Empty.
In "Lte Info" writes "Couldn`t start - Modem does not have serial interface!"
I can`t see any information from modem - Model, Current Operator, Signal Strength.

Can you help me?

Modem revision: 22.286.53.01..161

Did you try with RouterOS 6.8? Did you add dhcp client for lte interface?

Have you found any solution for this issue, yet? I have the same problem and I would prefer to be able to watch LTE info from inside Mikrotik and now connected to Huawei interface.

Thanks in advanced.
