Average routers are designed to send Wi-Fi in all directions but don't always reach every room. Range extenders improve coverage but create multiple networks for you to navigate. Deco M5 uses several units working together to replace your router and create seamless Wi-Fi in every room. Deco includes three separate features in one device - seamless coverage, antivirus and parental controls. Not only do you get strong Wi-Fi in every room of your home, you also get the most secure whole-home Wi-Fi with HomeCare protecting every device. 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. Devices automatically switch between Decos as you move through your home for the fastest possible speeds. A Deco M5 two-pack delivers Wi-Fi to an area of up to 3,800 square feet. And if that’s not enough, simply add more Decos to the network anytime to increase coverage. Deco M5 provides fast and stable connections with speeds of up to 1267 Mbps and works with major internet service provider (ISP) and modem. Deco can handle traffic from even the busiest of networks, providing lag-free connections for over 100 devices. TP-Link HomeCareTM provides a suite of personalized and secure features, including Parental Controls, built-in Antivirus and Quality of Service (QoS). Setup is easier than ever with the Deco app there to walk you through every step.
