Microcurrent r11e-LTE + sim MTS "For laptops, belemnit"
When I use the Internet in the office, everything is fine, when I come to the office in the morning there is no Internet, I reboot, everything works again, as if it is being cut down for inactivity, but MB is a coincidence.

What to sin on, on the Simcard or on the settings?
Googled the crutches:

spoiler

:local PingCount 30;
:local One 8.8.8.8;
:local ResultOne [/ping count=$PingCount $One interface=lte1];
:local Uptime [/system resource get uptime];
:if ($ResultOne=0 && $Uptime>00:02:00) do={/system routerboard usb power-reset duration=3s};

One of these days I will write to MTS mb they explain what the problem is.
Has anyone encountered this and how did you solve the problem?

Why such a crutch, there is a standard WatchDog
But for the best, you need to see the logs what happens when the Internet disappears.
