TP-Link Deco S4 Mesh AC1900 WiFi System – Up to 5,500 Sq.ft. Coverage, Replaces WiFi Router and Extender, Gigabit Ports, Works with Alexa, Deco S4(3-Pack)

I’m a Network Tech, These are Awesome
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 Deco app, and deploying them across the property was a breeze. The range on the units is impressive, easily covering 70+ feet and going through dense log-cabin walls. I was extremely impressed when one particular router which was too far away to communicate with the main unit had its traffic automatically routed through the next closest unit in a nearby building, daisy-chaining itself so that it could be connected and without any additional setup or configuration on my part. Speeds at all units were well within acceptable ranges, with all except one Deco getting over 100mbps download speeds. The mesh capabilities of the devices are very efficient and effective, with my mobile device automatically switching to the router with the best signal strength as I moved around the property.The Deco app made setup and management of the network very easy, with details like a network map, device heartbeat info, parental controls, and more. Adding all 6 routers to the network was easy and fast.This system ended up saving me time and materials, and saving my customer money because of how easy and effective it was at providing WiFi coverage around his property without the need for extra hardware or equipment.

good vlaue; high performance although simple setup without advanced settings
good value, the router seems to havae good speeds , better than FIOS router. The app is not as full function settings as higher end router, but honestly it is all we need.

Works perfectly with T-Mobile white box!
I live in an island surrounded by mountains. My house is made of concrete re-enforced with lots of metal. Needless to say, these are not good for Wifi reception. Recently, fiber optics became available in my neighborhood, but it’s rather expensive and the company does not have the best customer support. I chose instead to go with T-Mobile’s little white box and added the TP-Link Deco S4, which is affordable and gets good reviews. My concern was that the box is in my bedroom, near a window, and there are several concrete walls between it and the rest of the house. The installation guide recommends a clear line of sight between the units. It’s impossible to get that in my home. However, I have had no problem. Connecting this to the white box went smoothly. I did not even bother masking the original network. The system works like a charm, and the TP Link is totally compatible with my T-Mobile white box. I have strong signal in all 2100 square feet, all the way past my deep veranda, regardless of the walls between. Speed is fine. I am able to watch my streaming movies and shows with no problem.

Recently purchased the TP-Link Deco S4, and I’m seriously impressed. It delivers consistently fast Wi-Fi speeds across every corner of my 4-bedroom double story house—no more dead zones or frustrating dropouts. Setup was a breeze, and the mesh system handles multiple devices without breaking a sweat. Highly recommend if you’re after reliable whole-home coverage without the hassle. Great value for performance!

My home has 3 floors, and this works so well. Setting up was a breeze. And it looks aesthetically nice as well!
