These TP-Link mesh WiFi routers have been great and have worked well in our 3500 sq ft - two story house. These connect wirelessly to each other and they have two ethernet ports to connect directly to each other when connected directly to your ISP coming into your home.
The great news about TP-Link is that all of their mesh systems are compatible with each other and connect automatically (forward and backward) using the Deco app. Eliminate dead spots in your house with a mesh network system vs. a single router.
This is a great product and a game changer when it comes to whole home WiFi to give good coverage. Best coverage for home up to 5500 sq ft.
Buy a single unit or buy all three units for $75.00 and save.
Thanks for looking.
