This Google Product features the Google Seal for Online Marketplace when purchased from a seller other than Amazon. Google Wifi is an easy-to-set-up whole-home mesh Wi-Fi system. Google Wifi points work together to create a mesh network that blankets your whole home in fast, reliable Wi-Fi and eliminates buffering in every room, on every device – with coverage up to 4500 square feet.[1] It’s Wi-Fi that just works. [1] Home size, materials, and layout can affect how Wi-Fi signal travels. Larger homes or homes with thicker walls or long, narrow layouts may need extra Wifi points for full coverage. Strength and speed of signal will depend on your internet provider. [2] Minimum OS requirements are available at g.co/googlewifi/req. [3] Controlling certain devices and features in your home requires a compatible smart device.
