A:Answer Hi Brendan! The eero 6+ is a full router by itself, you just connect it to your modem like any other router and use the free eero app to set everything up! Once you've got the eero connected to your modem, the app will help you find great spots for the rest of them around your home to ensure you've got a great network connection no matter where you are! I hope that helps, have a great rest of your day!
