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. Each Deco mesh router can work independently to cover up to 1,500 sq. ft. and three units working together deliver up to 4,500 sq. ft. of fast Wi-Fi. For even more coverage, you can use up to 10 Deco units on a single network. 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. With just a few minutes and the Deco app, you can get your entire home network up and running. Just unpack your Deco units, download the 'TP-Link Deco' app for Android or iOS, and follow the on-screen directions. Deco will take care of the rest, even helping you place each unit in the best spot.
