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)

Absolutely Reliable! This mesh is seriously a tank. Always works. Never drops out. Comes back smoothly after power outages. She is not fancy, she is not expensive, her app is intuative and easy to use. She is super easy to set up. Has a very strong signal. Works on 2 level homes. I have 3 sets in 3 different houses and I 100% recommend this brand.

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.

I live in a 1970s two-story brick house with plaster walls that eat WiFi for breakfast. My old ASUS router + extender setup left me with zero bars in the master bedroom, garage, and back patio. After fighting it for years, I grabbed this Deco S4 3-pack on a Prime Day deal for $119 and it’s been flawless for the last 14 months. Coverage & speed Placed one in the basement office, one on the main floor, one upstairs hallway Full bars everywhere now – even the detached garage 70 ft away pulls 180 Mbps down on 5 GHz Real-world speeds: 450-550 Mbps next to a node, 220-300 Mbps in the farthest corners (on a 500 Mbps fiber plan) Zero buffering on four 4K TVs streaming at once + two kids on Fortnite + my WFH Zoom calls Dead-simple setup Took 12 minutes total with the Deco app (literally plug in, scan QR code, done) Seamless roaming – phone/laptop walks from basement to backyard without dropping a single YouTube frame Guest network, parental controls, and QoS actually work and don’t require a PhD Reliability 14 months uptime, zero reboots needed Survived two 4-hour power outages (units just come back online when power returns) Runs cool and silent (no fans) Only two tiny gripes No dedicated backhaul band (it’s AC1900 tri-band in name only – shares 5 GHz for clients and backhaul), but with wired backhaul option or good node placement it’s never been an issue No USB port or fancy features, but I don’t care when it just works For $119-140 the 3-pack is stupid cheap compared to Eero or Nest (which I tried and returned). If you have a big house, thick walls, and just want rock-solid WiFi that you never have to think about again, buy these before the price goes back up. Already convinced three neighbors and my parents to ditch their old routers for the exact same kit. 10/10 – best money I’ve ever spent on networking. My WiFi problems are officially dead and buried.

Worked out of the box. I like the fact that each device has 3 Ethernet ports. I have desktops, servers, and VOIP phones - having wired connection is really nice. Big minus for me - no management console through the browser and very limited capabilities through mobile app. For $100 device I expected much more. That said, TP-Link has never been strong in their software capabilities.

The price is worth it. I used to have to reroute my old router at least once a week. TP-Link has only needed to be rerouted because the modem have been updated or issues with the service provider. I love how fast everything is working. Before there was a lagging in the bedroom far east away from the modem more than 100 Feet coverage. But since I changed it to the TP-Link I can even close the door to the room and there has been no shortage in coverage at all. Love the way it looks, easy to install and no interruptions have been experienced, I have it for more than a year, this is one I highly recommend. I bought three to cover all weak coverage. One in the office near the modem, one in the living room and one in the far east of the apartment with brick walls. Keeping me logged from every angle with no LAN issues. And this was recommended to me by my internet provider installation man. He had come out to service their router more than it should.

Fué sencillo de instalar, me tardé aproximadamente 1 hora en todo el setup, los equipos se conectaron rápidamente, incluso la impresora wifi con conexión wps fué sencilla de configurar y trabaja muy bien. Equipo excelente en el área de oficina apenas me llegaban 8-9 Mbps (con un repetidor) ahora tengo de 90-100 Mbps, mi computadora principal (una viejita Asus de 2012) a cada rato se caía el wifi y ahora está estable, también pude configurar mi streaming de música desde la oficina hasta la sala dónde se encuentra el Deco router y trabaja muy bien sin cortes.

Works well, covers my whole house much better than my sky max router. Be warned if you buy this from Amazon America (because it is ⅔ the cost in UK) the power supplies come with American plugs so need to buy shaver adapters.

Funciona muy bien!

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!

No UK plug / adaptor you WILL need to purchase a ‘step down’ converter before using this device in the UK.
