I have a Panasonic toughbook laptop model FZ55-2. Windows 11 pro.

I use this for work and it requires me to dock the computer in the car to be charged. We purchased the vehicle used along with the laptop. The issue I’m having is when I dock the computer it tries to run the internet off the old modem. The modem is hard wired into the dock. I have unplugged the modem. We use aircards (simcards) for internet from ATT. I can’t drive the vehicle with it undocked due to it flying around my car. When I undock it. I have to reconnect the internet which isn’t an issue it’s just becoming annoying and inconvenient.

I’ve disabled the ethernet connection via the software but it still doesn’t help. I can’t find the setting to make the sim card the priority internet connection.

Any help or insight would be great. Google didn’t help much.
