TP-Link Deco S4 AC1200 Whole-Home Mesh Wi-Fi System, Qualcomm CPU, 867Mbps at 5GHz+300Mbps at 2.4GHz, MU-MIMO, Beamforming, Work with Amazon Echo/Alexa, Pack of 3

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!

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.

Deco S4 3 Pack - Setting it up with Virgin Media Hub 3.0 in Modem Mode - 350mb package Bought these again as the first kit simply wouldn't connect to the internet no matter what you tried. Wireless setup - deco talking to each other over wifi.... Great concept but sadly it uses too much of the available bandwidth to stay connected - household with multiple devices like smart tvs, tablets, cameras etc would struggle as it reduces your overall bandwidth which affects the speed. Ethernet backbone setup - deco talking to each other over Ethernet... This is by far the best method to connect these units together, with gigabit backbone, you free up your entire wireless bandwidth for devices to use therefore you maximise on your broadband speed over wifi. This method also will allow you to have more than 3 deco units all over your house - especially houses that aren't square in shape. Adding Gigabit Switch.... I am using 2 ethernet 8 port gigabit switch with 2 of the decos - this has allowed me to take fixed devices off the wifi thus freeing up bandwidth for more portable devices like tablets, phones laptops etc. Fixed devices - tvs, set top boxes, pcs etc. 2.4G & 5G... 5G is the frequency to use as the2.4G has really poor bandwidth & speed, Virgin Media 3.0 Hub gave better speed over 2.4G than these decos. Over the 5G speed test showed full speed provided by Virgin whilst you were in the same room as the deco. Of-course speed will decrease as you distance yourself from the decos. Make sure you enable Fast Roaming - so you have true seamless experience - as this feature will ensure you devices gets moved from one deco to another seamlessly ensuring you stay connected to wifi. Beamforming is worth enabling as this ensuring your wifi devices get the most bandwidth from the deco majority of the time. Not sure if this works on all devices. Be patient & be aware.... The deco units takes time to settle down, as they don't give you full speed straight away. Probably because of the beamforming tech or some other variable. Earlier speed test were quiet slow, awhen other devices started to come online & deocs were running for hour or so, noticed the speed test were going up in speed until i reached the max speed virgin provided me over wifi. Where to place them.... Using Ethernet backbone setup -does allow you to place them quiet far apart ensuring you get maximum coverage in your house but be careful that you don't put them too far apart so you eliminates your seamless mesh wifi bubble - use wifi analyser to see what the wifi is doing & then place them accordingly in your house. Functions & Features.... Word here is BASIC - there isn't even a option to separate your wifi frequencies e.g. 2.4g & 5G being advertised as 2 wifi's; so choose which you connect to rather than deco deciding it for you. Also there is no feature to select wifi channels, which is a huge drawback. Not all places in a house will have same channel behaving equally, therefore having the ability to select a channel is needed. So you can select the best channel for the area where each deco is placed. App... Really easy & simple to use app that anyone can use, it gives really good insights on which deco a device/s is/are connected to & how much bandwidth they are consuming. Also monthly report is good overall view of connected devices & bandwidth used. You can also control the deco via the apps from remote location, so you can both monitor & control settings including blocking devices & rebooting decos etc. It is also, very easy to create Guest networks and you can have multiple admins on the apps, allowing multiple adults to have control. Parental control is really stupid in all honesty & takes ages to setup up & it not intelligent at all - therefore I didn't bother setting it up. Are these worth buying.... Yes they are IF you use the Ethernet backbone setup otherwise, these are hit n miss depending on your house & environment e.g. some houses are thicker walls which WILL have a affect on the wireless range & performance. Verdict... If you have a big house or house with extension or thicker walls, these are a must have when using ethernet back bone setup - whilst the product is great & it simply works & performs well - I just can't give it 5*'s as it doesn't have basic options like separating wifi frequencies & be able to select wifi channels.

Outstanding mesh network. Bought this to partner with a new Starlink installation. Starlink router is in bypass mode and Deco slotted right in. Really easy to install. I setup a hybrid wired and wireless backbone network across my home, total coverage across all floor, rooms and garden. Deco app really intuitive to use.

I use this with 1Gbit fibre and Ethernet backhaul, and it works flawlessly. Setup was a breeze, and each node delivers the full speed. Signal strength is great throughout the house, and devices such a phone connect to the nearest/strongest hub automatically. In hindsight, I'd probably have preferred the 2.5G Ethernet version, but I don't currently need it. The only downside is needing to use Ethernet hubs to expand the number of wired connections, but these also worked without issues.

WiFI 7 Mesh - well i wasn't sure what to expect. My previous Netgear Nighhawk was over 5 years old and one of the base units had failed so I did my research and purchased the BE3600 3 pack. Arrived the next day and I took the plunge and went to install straight away. Used the App to install and was very easy to do so. Positioned one off the router, one upstairs and the other one in my Summer Room which is about 25m from the base unit. I did connect this one via an ethernet cable which was previously installed. Very easy to do, and after a few minor set up issues (my fault) the system was up and running and delivers solid WiFi around the house. All Ring products re-installed, TV's, iPads, laptops etc all very easy and up and running. We have 900mbs hard wired and getting between 80-250mbs around the house and Summer Room. Excellent product and bought for £187. So far so good and very pleased with the new Mesh System.

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.

Very happy with these. Easy to set up, very stable and reliable. Good app too. And a reasonable price.

WLAN Signal ist nun einfach super. Je höher die Decos sitzen, desto besser die Reichweite.

Mi è stato consigliato ho voluto provarlo e devo dire di essere molto soddisfatta in tutta casa ora abbiamo collegato wifi che prima non si aveva.

Decos seem to lead the meshing way. Very reliable. One brick out of ten, but managed to pull even that one back.

very good speed
