Ethernet and wifi connections (at same time)

[MookJong]

Is it possible to connect a laptop to a standalone device on one IP subnet and also be connected to a domain network via the WiFi card at the same time?

I have done this before with two Ethernet cards in a PC. One connected to an industrial device and one to the office network.

But can it be done via Ethernet and WiFi? I can't find a straight answer online so I'm thinking nope.

Yes it can. I regularly have my wifi connected to get to the internet and then the ethernet connected to a local (non-internet) device for local setup.

Yes - each network connection will have it's packets routed based on the subnet assigned. As long as the 2 network connections use different subnets.

For example, your wifi subnet is on: 192.168.0.0
Your wired connection is on the 192.168.1.0 subnet.

You also need to ensure the default route is through the wifi. Sometimes Windows can get confused which is the default route.
