Perhaps this is a novice question, but:
I am dealing with two LANs: LAN 1 is a wired Ethernet connection to a small test network that is not connected to the internet (this is forbidden), used for monitoring a handful of connected devices. LAN 2 is also wired Ethernet through my dock, through which I have an internet connection. Each connection has its own network adapter.
Right now I use batch files to disable one adapter and enable the other adapter and then assign an IP when I want to switch networks. This is clunky, because if I'm connected to the test network and I need to quickly google something, I have to switch adapters, which takes ~1 minute or so round trip, and this downtime is really starting to add up.
Is there a way I can stay connected to both LANs without having to disable and reenable network adapters?
