With advanced Deco mesh technology, the three Deco 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. With support for Wi-Fi 5 (802.11ac) and three separate bands (5 GHz, 5 GHz, 2.4 GHz), the Deco mesh network can provide up to 1.5 Gb/s. A Deco 2-pack can cover up to 4,500 square feet, while a 3-pack or more boosts the range even farther.
Deco M9 Plus acts as a hub for your wireless and smart-home devices. You can adjust settings and create interactions from one app. The Deco can also handle traffic for up to 100 devices. You can also use TP-Link HomeCare, which provides personalized security features, including parental controls, built-in antivirus, and Quality of Service (QoS). Setup is easy via the Deco app.
