Hi

I am currently using a Mikrotik LHG external antenna, I am having an issue where
the device stops passing data to my network, however when I login to the configuration
it says I am connected and have a strong signal, If I restart the router the data begins to pass as normal.

Is there away I can make the router restart by itself at a specified time or alternatively have it send a "keep alive"
request to the the 4G provider when it hasn't been in use for a while?

Thanks

can anyone help with this?

Read about Tools/Netwatch for down detection and action.

Another, less intelligent, is System/Scheduler to schedule a System/Script like disable/enable or reboot script
