More info- I currently have a Google Nest Wifi Pro router. It's a mesh system and am really happy with how it works. The main drawback is that it only has 1 Lan port. It also sits out on my desk and is not hard to accidentally unplug.  I don't want to get rid of my current setup. daisy chaining routers crossed my mind- I could use a router with multiple ethernet ports to potentially isolate my two systems, but there's got to be a better tool for the job, right?
