Nest Wi-Fi blankets your whole home with reliable Wi-Fi coverage (Home size, materials and layout can affect how a Wi-Fi signal travels. Larger homes or homes with thicker walls or long, narrow layouts may need extra Wi-Fi points for full coverage. The strength and speed of the signal will depend on your Internet provider). Automatic updates help your network stay safe and sound. One Wi-Fi router with two Wi-Fi points is strong enough to handle up to 300 connected devices, and strong enough to stream multiple 4K videos at a time (This is based on only using connected devices at a data rate of 1 Mbps each. Requires sufficient broadband Internet connection and connected devices to be located within the Wi-Fi coverage area described at g.co/nestwifi/coverage. The strength and speed of the signal will also depend on your Internet provider). And your Nest Wifi point has a speaker with the Google Assistant for extra help around the house. This is Wi-Fi as it should be.
