Deco uses a system of units to achieve seamless whole-home Wi-Fi coverage — eliminate weak signal areas once and for all!* With advanced Deco Mesh Technology, units work together to form one unified whole-home network with the same network name. Deco automatically chooses the best connection for your device as you move throughout your home. A Deco M9 Plus two-pack delivers Wi-Fi to an area of up to 4500 square feet. And if that’s not enough, simply add more Deco units to the network to increase coverage.* A dynamic backhaul up to 1.5 Gbps ensures you have fast, stable connections throughout your home.*** Deco M9 Plus acts as a hub for your wireless and smart home devices. Adjust settings and create interactions from one app. Deco can handle traffic from even the busiest of networks, providing lag-free WiFi connection for over 100 devices.* TP-Link HomeCareTM provides personalized security features, including Parental Controls, built-in Antivirus and Quality of Service (QoS).** Setup is easier than ever — The Deco app will walk you through setup step by step.
