LTE WIFI Switch

Hello together,

I want to have a constant connection to the internet in a local network I set up in my car. I’m already using a Metal 52 AC for accessing open WIFI while driving around.
Now I want to add a LTE component which connnects me to the internet while theres no WIFI available. Did anyone ever do something like a WIFI-LTE-Switch which is switching to ethernet from the LTE component while there is no available WIFI connection an switching back when there is?

I hope my problem is understandable if not don’t mind asking :slight_smile:
