Hello,
An ISP, such as Comcast or AT&T, provides Internet service to your home (or business). ... Your ISP takes care of getting an Internet signal to your house. Once you plug an eero into your existing modem and set it up, eero takes care of everything else and begins covering your house in WiFi.
Thanks.
