Netgear Modem/Router combo and Eero 5 Router. The Netgear can do both, but the Eero has a much better Wifi range. The Eero needs a modem - it is a router only. This combination has everything you need for a coax in Internet hookup.
I currently use the same Eero model for my 1,100 sqft house with a different router, and it has a great signal. Selling because I used to use both Eeros in a larger house and no longer need the coverage of two. This one is advertised for up to 1,500 sqft on its own.
Willing to accept a return within one week if it is not working as expected.
