I'm working at home via internet and I can't allow myself to get disconnected therefore I want to use a back-up internet.

I have two Internet connection at home, one normal router (using optical fiber) that is connected via Ethernet to my workstation and the second is a 4G router that has sim card and battery (I want to use this one as a back-up) that I want to connect via Wi-Fi.
I read a little about the bridged connection on Windows and I don't know if it's the best option to use here, and also I don't understand why it chooses the Wi-Fi connection over the Ethernet one, while I want the opposite.
Thank you.
