That makes sense! Mine is 2200 sqft. I think with modem in the basement and AP on the main-floor via cat, I should be good

Thank you for the response. If a add a router, would all the wires have to run to the router? I’m thinking of running all the wires to the modem in the basement and then have a router on the third floor through cat 5 port. Am I thinking about this correctly?
