eero is the world’s first whole-home WiFi system. Only one eero needs to connect to a modem. Additional eeros simply need power from a standard outlet. They automatically connect to form a wireless mesh network that covers every corner of every room. For coverage in even the most challenging situations, your signal will cover your home in Mesh Wi-Fi technology and is scalable to any number of eeros. If you already have Ethernet wiring, you can always choose to hardwire your additional eeros.
