There was a problem, the Huawei E3372 modem is constantly disconnecting, how to reconnect (auto-connect after a specified time)?

Answer 1

You missed a word in the question. I assume that the problem is that the modem is constantly disconnected.
Your modem can operate in two modes: Stick and HiLink.
With the Stick firmware, the modem will be seen as an AT-modem, to connect to the Internet you need to "dial".
With HiLink firmware, the modem appears as an Ethernet network card, and does not require settings in the OS. In this mode, the modem itself manages the connection state.
What mode do you have?

Answer 2

STICK
