How to switch between 2 boarding schools on one computer?

Question

Computer networks

There is one computer. He has 2 network cards. Each entrance has a separate independent Internet (A and B).
My computer constantly uses Internet A, regardless of which port is inserted.
How can I change the settings so that Internet B is the main one? I just can’t disconnect, because there are network devices on network A that I need constant access to, and I can’t transfer them to network B.

Answer 1

In the settings of the network card A, remove the gateway. In the settings of map B, register the gateway (gateway for network B). The Internet will go through B. This is if manually.
