Deco S4(3-pack) AC1200Mbps Whole-Home Mesh WiFi System, Router and Access Point Modes, 370 m2 Coverage WiFi Booster, 867Mbps at 5GHz+300Mbps at 2.4GHz, Beamforming, Work with Amazon Echo/Alexa

Bought this for my parents stone built bungalow. The wifi signal would not reach all rooms and this meant they couldn't use their smart tv in the bedrooms and conservatory. Also they Invested in a security system and only one camera worked intermittantly. We tried the TP Link booster and this made no improvement HOWEVER after looking into this further we came across the Deco system. WOW they now have wifi in all rooms, no buffering from smart tv it works perfect. Security cameras all work with no issues, parents very happy. The system is very easy to set up and connectivity is no issue now. Signal strength is great throughout the house. Would highly recommend this system and even looking at getting one for my house.

I recently had Fibre broadband installed. Openreach would only terminate the ONT downstairs in the kitchen. I have a 3 storey house and have previously had a Wifi router connected to FTTC terminating on the middle floor where my study is located. I had to completely rethink my topology! The Deco system has been setup with wireless back-haul. I am using PPPoE on the main Deco unit to connect to my ISP via the ONT. I have one unit on each floor. The Wifi speed I get when connected to 5Ghz network is generally very close to the ISP speed and the 2.4Ghz network is more than adequate but obviously limited on speed. I also have a Mac connected on the first floor via one of the Gige ports and it runs at the full ISP connection speed and that includes a wireless back-haul hop from the Deco it's connected to and the main Deco connected to the ONT. All in all I'm very impressed with how easy it was to setup and the performance I'm getting. My ISP speed is 150Mpbs and most of the time this is available to me with devices that are capable both wired and wireless. I suspect if a much higher speed broadband connection is used the wireless back-haul would start to become a bottleneck and in this situation wired Ethernet via the GigE ports is available. There are 2 on each unit. This may be limiting if you use back-haul on one port and connect the other to the ONT then you're left with no ports on that unit to connect to your wired LAN. Since I originally wrote this review, I have managed to set up backhaul over a LAN using a TP-Link TL-SG108 switch which also has various wired objects plugged in (Smart heating bridge, printer and a MAC). In this case everything is working well and I am getting the full 150Mbps through the MAC. I suspect backhaul is possible over most LANs but I know there are complications with VLANs if you are using the Guest Network feature. In this case you may have problems with some switches depending on how they deal with loops caused by VLANs. I don't use the Guest Network so I haven't had a problem. It doesn't boast many features but as a basic router/mesh Wifi it seems like a very cost effective and stable solution.

Overall, this item is very good. I set it up with Community Fibre using a Linksys router and chose to configure it in Access Point mode instead of mesh. The first unit is connected directly via Ethernet to the Linksys router on the ground floor and acts as the main hub. The second unit is set up wirelessly on the second floor, directly above, and the third unit is wired via Ethernet on the third floor. We have a 1Gbps connection, and while that full speed is only achieved on the ground floor where the Linksys router is located, the overall performance has been excellent. The second floor (wireless) gets around 180Mbps, and the third floor (wired) reaches about 580Mbps. While you won’t get the full 1Gbps throughout, the speeds are more than sufficient, especially since most of our usage happens on the ground floor. One of the best parts of using Access Point mode is that I was able to keep the same WiFi name and password as our Community Fibre Linksys setup, so the transition between floors is seamless. Setup was straightforward and hassle-free, which was a refreshing change from my previous experience with Mercusys—never again!

I purchased the TP-Link Deco M4 Whole Home Mesh Wi-Fi System in July 2025 for £125. While the price has since dropped to £99, even at what I paid, this system has proven to be an excellent investment and I highly recommend it! The packaging was straightforward and easy to open, and the product units looked good right out of the box. The main feature that attracted me was its promise to eliminate Wi-Fi blind spots and extend coverage throughout my home. And it delivered! Setting up the system was incredibly easy: you just plug one unit into your main router, place the other two strategically around your house, and follow the simple, intuitive steps in the Deco app. Previously, I had frustrating dead zones in about half of my house, but now I have a strong, fast connection even out in the garden! The Deco M4 also offers some fantastic secondary features. The app allows you to create multiple Wi-Fi networks (e.g., for personal use, guests, or a general "everybody else" network). In our home, we've set up three: 'this one' for my partner and me, 'the other one' for family and friends, and 'that one' for everyone else. This is incredibly convenient for managing access. Another useful feature is the age restriction capability for specific networks, which is great for households with children. You can also monitor the internet usage of each connected device through the app, which provides good insights into bandwidth consumption (though it doesn't track specific websites visited). The setup process was a breeze, taking less than 5 minutes to get internet flowing throughout the entire house thanks to the app's step-by-step guide. For multi-story buildings, a bit of strategic placement of the units is key. The first unit needs to be close to your main router, though you can use a longer Ethernet cable if needed for placement flexibility. It's important to note that you will end up with at least two Wi-Fi networks in your home – your original provider's network and the new, superior network created by the TP-Link Deco system. The units themselves feel robust and well-made, crafted from strong plastic, indicating good build quality that should last. For the price, the value for money is excellent. My entire house now enjoys very fast and stable internet, which was previously only true when I was standing right next to the main router. Pros: Super Easy Setup: Quick and intuitive setup process via the app. Very Stable and Fast Internet: Eliminates dead zones and provides reliable high-speed Wi-Fi throughout the entire home. Multiple Network Creation: Ability to set up separate Wi-Fi networks for different users (e.g., family, guests). Useful App Features: Parental controls (age restrictions) and device internet usage monitoring are very handy. Cons: You will end up with at least two separate Wi-Fi networks in your house (your original and the Deco network). I wholeheartedly recommend the TP-Link Deco M4 Whole Home Mesh Wi-Fi System. It's a game-changer for home connectivity, resolving Wi-Fi issues effectively and providing robust, fast internet everywhere. Definitely a 5-star product!

I’d been looking for options to boost my signal around my house for a while. I’d tried the standard plug in boosters but had issues with the signal dropping out. I was a little wary about a mesh system, partly because of price and partly because I didn’t know anyone who had one. I’m so pleased I took the plunge. I bought this before the amazon event which was a bit disappointing but I can honestly say it’s completely transformed our WiFi experience at home. The set up is straight forward, however you do need to know the type of security settings your internet provider uses before set up. That took a little longer as I had to call Vodafone to confirm, shame there isn’t a list available somewhere by region. Once that small hurdle was navigated set up was simple. Simply plug in the first router and follow the prompts on the app. I now have great signal in every nook and cranny of my house. I have an old Victorian terraced house , and a fair share of thick walls . The worst place for me was the back bedroom which is where I’ve set up a temporary office to work from home. I struggled to get 5mbps download and less than 1mbps upload. Now I have the full 40mbps down and 9mbps up! No more interrupted zoom/teams calls!! The units are fairly unobtrusive and designed nicely. I would definitely recommend this system, if you have a stable internet connection but struggle with the WiFi reach then this will fix it! I’m using all 3 units, however my 3 bed house on 2 levels possibly only needed 2 of the units. I have one in my kitchen which does a great job of getting WiFi to the end of my garden! Spotify works a treat for a bbq, just need the weather now!

I bought these so sort out my WiFi for some ring cameras. All are now on the same network and coverage is great. My house is built of stone with walls up to 4 ft thick. Easy to set up and so far (6 months) very reliable. Handy guest setting too

Since jumping onto fibre optic, my connection has been crippled by a particularly well-known awful modem. The signal would only stretch the living room before diminishing to abysmal levels in the kitchen and upstairs. The most unfair point being your provider knowing how terrible the router they send you is and expecting you to dish out for your own one. I had enough and fortunately like with devices I have purchased from, TP-Link offer yet another relatively inexpensive, super-value solution. This mesh system works by using nodes to carry signal around the house for amazing high-speed, full-house coverage. Connecting just two from the set of three defeated all wifi dead spots in my brick-walled house that my Virgin HomeHub 3 could never imagine doing. Design: I purchased the three-set TP-Link S4 Mesh system which meets 100mb+ fibre-optic speeds and up to 4,000 ft coverage/3-5 bedrooms/three-floors. The threes nodes are packaged neatly inside the box, arriving with one ethernet cable to connect your modem and three power cables for each node. TP-Link has done a tremendous job designing the look of this mesh system, discreet and supremely minimalistic. Each node has two ethernet cables that prove essential for your first node if you need to connect other ethernet powered devices like Eufy's Homebase as one port will already be occupied by connection to your Virgin/Internet router. A small TP-link logo light exists above that surprisingly proves enough symbolism for setting up this whole unit. Setup: Setup with your internet router or Virgin HomeHub is made simple and easy for any user through TP-Link's Deco app but can still be fiddly at first. The first step is to download the Deco App and the subsequent steps are all provided if you follow through on your device. Next, place your internet router/Virgin HomeHub on modem mode. Do not worry, this is fortunately made simple by Virgin, enter 192.168.01 in your browser while connected and login into your router to find the modem setting. If you did not know, the login can be found at the bottom of your HomeHub router. Now click and enable modem mode. Be warned, this now means you can only connect to the hub with an ethernet! (This is all reversible if you're worried) With modem mode enabled, use the ethernet cable to connect your first TP-Link Deco node to your HomeHub's first Ethernet port. If you continue through on the app you should be all connected! If your node gets no internet connection from the HomeHub, I have the solution! I discovered, as the app briefly mentions, you need to turn off and turn on the TP-Link Node and HomeHub router at the same time. This is because when the Homehub is turning on it searches for a router connection and shortly turns off after when not found. Once the first node is set up, enjoy setting up the other two in different ends or levels of the house, using the app again to pair them together. Connection: The connection finally reaches full fibre-optic potential around my house. Not only do the three nodes together get signal around every downstairs, from living room, kitchen, garage and garden but also upstairs across multiple bedrooms to maximum speed. I pay for Virgin's 100Mb connection and easily reach 80Mb to 100Mb+ in all rooms with these nodes. The ping stays below 20ms, the connection being stable all day long. I long dreamed of connection reaching everywhere, I am so pleased TP Link's relatively cheap Mesh system resolutely makes this a reality.

Mesh networking, I was late to the party having struggled with multiple routers, bandwidth controls, multiple WiFi networks was a revelation. I'm more than capable with networking, flashing custom router roms, setting up parential controls, QoS, VLANs..... but sometimes you just want a network that works and not have to touch it, I've better things to be spending my time on. Enter TP-Link Deco, it just works. The setup process is via smartphone app, it detects its way to the internet all by itself and you are pretty much done. Parental controls are pretty good, allowing on/off (bedtimes) per person and some lightweight website filtering. Essentially you can name all your devices that connect to the network and assign each of them an 'owner', these 'owners' are then parentally controlled, i.e. all devices for that owner will have the same behaviours. QoS is very simple, but enough. This is 'per device'. Essentially you set the devices you want to have 'high-priority', this might be the living room TV, or (as in my case) my work PCs. If you are a technical user wanting control of every aspect of your WiFi, this kit is not for you. You cannot set channels, channel bandwidths, transmit power or barely any 'advanced' settings. It's not perfect, here's a few flaws: 1) Devices are registered and assigned by MAC address. Both iOS and Android devices in their latest guises have 'randomised' MACs, which can play havoc. It shouldn't as these MACs are supposed to stay constant per WiFi network, I do however have 1 rogue Android device that picks a new MAC everytime. Your kids may also know how to 'spoof' MAC address to circumvent parental controls. It would be nice if new MACs (aka new devices) were blocked by default on the network. 2) There is no dedicated backhaul (this involves a WiFi channel dedicated for node to node conversation). My internet speeds are less than 70Mbps, the lack of a dedicated backhaul makes little or no difference to me as the WiFi speeds far outstrip my internet speed. If your requirements are less internet connectivity, but more local network communication, this might be more important to you. 3) Existing DSL Modem/Routers present some difficulty. No real fault of the Deco, but if you have an existing DSL modem/router setup isn't really done without some fiddling. You essentally need to 'dumb down' you existing modem/router a) It's WiFi really shouldn't be on b) It musn't be a DHCP server. Some modem/routers offer a 'bridge mode', which essentially turns them into a modem only - this is ideal, then you input your ISP login into your Deco. You 'can' put the Deco into access point mode, downside here is you loose parental controls and other features that you only get when the deco is in router mode. If your existing router is still acting as a router, everthing will still work, it's just you get a double-hop out of your network - for the non-techical this might be a 5 MILLISECOND delay (not that you would notice). The potentally bigger issue with this double-hop is for gamers, especially if inbound traffic cannot get back, here you can put your Deco in the DMZ of your exisiting router. None of this should put you off the Deco, technically it is brilliant, I've been montoring its WiFi behaviour over some time, and its incredibly sophisticated under the covers, optimising the node configuration for maximum performance and stability. For most people it will just work out of the box, 1) One single WiFi network identity throughout your home 2) Seamless roaming as mobile devices move around the house 3) Simple 'app' based control and monitoring It's the best investment I've made in WiFi hardware for years.
