I have a scenario where I need to be able to connect to devices on a private local-only WiFi network while simultaneously connected to the Internet from a different adapter. However, Windows 10 will not let me have to WiFi adapters active and connected at the same time.
Assume a computer with two interfaces (forget even that they're WiFi). Interface A (192.168.1.2/24) connects to the WiFi router (192.168.1.1). Interface B (10.0.1.2/24) connects to a local network (10.0.1.0/24). There is only one default route: 192.168.42.1. The computer will have a routing table something like this:
default gw 192.168.1.1
Interface A 192.168.1.0/24
Interface B 10.0.1.0/24
In my scenario, the laptop's built-in WiFi adapter is Interface A. A USB WiFi dongle is Interface B. The interfaces would have no conflict and there would be no confusion about default routes. I am not trying to use the computer as a router between the two networks. I only want to be able to access both networks simultaneously from the computer.
The only thing preventing me from setting this up is Windows' refusal to allow two adapters to be connected at the same time. Is there some way to lift this restriction?
