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 a unified network with a single network name. Devices automatically switch between Decos as you move through your home for the fastest possible speeds. A Deco M4 two-pack delivers Wi-Fi to an area of up to 2,800 square feet. And if that's not enough, simply add more Decos to the network anytime to increase coverage.
