Sure.

For the script to run you only need the requests module which you'd usually install with pip in this fashion:

pip3 install requests

I will make a new version of the script to remove this dependency.

Mexoh1To7kI tried several times to reply again but my posts disappeared. I don't know why.

So I try again without code.

My Model is from europ (1100-100EUS)

FW: 12.06.11.00

I ran your script again the last two days over night without success. When I manually uncheck mobile data in the mr1100 while running the script it does its job but not when the connection gets cut by the provider over night.

That night it was disconnected an your script didn't work.

I manually killed the script, started it again that morning  (about 5:30 am). As far as I can tell it stucks on  "Data appears to be disconnected, reconnecting..". till my ssh connection was timed out.

I have a external server monitoring my connection status. So I can tell that my router was offline from 5:23 to 8:24 am.

Could you provide a solution to get a working logfile from your script?

I tried with

python script.py IP PASS >> logfile

But this did't work and I have no clue how to use the logging module in your script ;)
