When I used to do this, I just bought a $60 router to hang off the main router, and used that router to connect the devices I watched baseball on, and left the main router untouched for the rest of the household.
Got a suggestion for a router? Specs I'm looking for? I would ethernet it to my "main" router and can run ethernet off it to the main TV?
Edit: Oh I see, there are lots of $60 router options.
