Mikrotik ATLGM internet problem

RouterOS General
1

Hi, we use on one location mikrotik ATLGM antenna with SIM card inside.

It has default configuration with custom APN.

It is on ROS 7.15.3 and firmware is also on version 7.15.3.
LTE modem firmware is on latest available (EG18EAPAR01A13M4G_01.002.01.002).

We started to having problem before few months. It has no connectivity in the morning when people come to the office. After they restart the antenna by unplugging the cable it has connectivity again.
As long as they work internet is stable (few times they had to restart it) but every morning they have to restart antenna to have internet connectivity again.
It is like some kind of power save and it is driving me crazy.

It is not due to ROS because problem was same on the 7.15.2 version.

Any advice would be appreciated. Thank you.

Does just disabling / enabling (with short delay) lte interface solves connectivity issue without need to restart ROS in antenna?
If it does, simple Netwatch script can be made to do this upon connectivity loss.

I will try that and get back. Thank you.
