The Deco S4 is a fantastic mesh Wi-Fi system. It’s easy to set up through the app, and adding devices is simple and intuitive. Wi-Fi speeds remain consistent as you move from room to room, and the system handles multiple devices smoothly. It’s also easy to configure passwords and create a Guest Network. Newer S4 units include additional features like an IoT network option and the ability to manually assign which satellite Deco connects to which primary node—super helpful for optimizing placement.IMPORTANT TIP for Ethernet Backhaul Users:If you plan to use Ethernet backhaul (which I highly reco
I have Verizon FIOS bundled service, so I have my TV, phone and internet all-in-one. While I do love FIOS, one of the negatives is that I had to use their bundled Gateway modem/router because of my TV and phone services. My house does have a wired ethernet network running thru it, which is great for all my desktop PC's and Home Theater setup, but the FIOS Gateway router's WiFi performance didn't adequately cover my three floor house (the FIOS modem is in my garage, next to my home wired-network box). To help solve this issue, I tried using the very well reviewed Netgear EX6200 range extender,
Excellent product, good solid coverage and speed. Fairly easy to set up if you have a bit of technical knowledge. Instructions are otherwise clear and can be easily followed even if you don't have a lot of technical experience. Would definitely recommend purchasing if you have blind spots with your internet from room to room and especially if you have concrete walls. Excellent performance and does cover 5000 sq ft
Setup was painless. The app walks you through it and I had it up and running without any of the usual router headaches — no digging through admin pages or troubleshooting why devices won't join.Since then it's just worked. Connectivity has been steady across the house and I haven't had to think about it, which is really all I want from a mesh system. Devices connect, they stay connected, and I'm not power-cycling anything.Easy to recommend if you're replacing a router that's been giving you dead spots.
I work as a data network technician, and these routers are awesome.I bought two 3-unit kits to build a WiFi mesh network for a customer on a large, multi-million dollar mountain property with four buildings including the main house. I was expecting to have to run network cables and utilize long-range point-to-point transceiver antennas to get WiFi to the farther outbuildings, but the Deco routers were pushing strong enough signal and automatically connected to each other in a such a way that cable runs and extra antennas weren't necessary.The routers were extremely easy to configure using the
After doing a lot of comparison shopping, I ended up settling on the TP-Link Deco S4. My biggest factors were price, reliability, and range. I have a three floor 4500 sq/ft house built in 2003. The Verizon Fios Gateway router worked, but it suffered considerable slow down as I got to the extremes of the house. With the new three node Deco S4, I get full speed internet at every floor and extreme. Previously, I was able to get 100mb/s maxed out at the router with minimal traffic, but dropped down to 10 mb/s at the extremes of the house, especially the basement and some bedrooms. With one of thes
These are great. Pretty clear on how to set it up. Only issue is one constantly needs to be plugged into the router, didnt realize it, but no big deal. Easy to navigate, easy to monitor with the APP. Its a solid purchase.
