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

After struggling with bad and unreliable signal for about the last 10 years I bought this after a friend recommended it. Honestly the best purchase ever! I’ve tried numerous things over the years all of which had their issues. Repeaters, extenders, powerline adapters, using the same SSID, using different ones, Changing the router, upgrading, moving location, you name it I tried it. I’ve used a number of TP Link extenders before and whilst they did improve things considerably they were not a patch on this! My 1930s very solid walled 4 bed house didn’t let the signal travel very far. Now there’s literally nowhere the signal can’t reach - and at full speed. At last I can now get the full use of my fast Virgin broadband everywhere around the house without any drop outs. It bypasses the useless Virgin router and just uses the very good Virgin connection. Who knew the connection was so good! It was just hiding behind a useless router!! (And I’ve had a few) No need to re-boot everything regularly, or wonder why it’s not working today, it just all works. This Deco S4 3 pack replaces my previous 5 unit powerline (TP Link) set-up. It’s far, far better in every way, speed, reliability, connection, reach. There’s absolutely no comparison. If you’re thinking of getting one, just do it! I’ve been using it for a couple of months now and have not had one issue - ever. Just perfect connection on every device in every room including 4K Wi-fi streaming and gaming in multiple rooms. No buffering on streaming, no lag on gaming just perfect upload and download speeds everywhere. No need to Ethernet anything, the Wi-fi is so fast and so reliable everywhere. For the first time in 10 years everyone is happy with the broadband - Everywhere and all of the time!!! It should be standard for every broadband package. If you enjoy getting stressed out with unreliable broadband it’s not for you. If fast, reliable broadband everywhere around the house is important to you - just buy it now!

As a supposed introduction to a mesh system on a budget this is excellent. Bought this based on the reviews and I am not disappointed, provides an excellent signal through out the house now after having some drops from my current router/provider. Outdoors is fully covered also after location of the second box towards the rear of the house. The increase in speed is really noticeable and this was confirmed with a speed that doubled at least my previous best. Set up was really easy through the Deco App and was able to retain my current provider and password details so no apps or products had to be re set to the Mesh system. Excellent product at a great price, that should cover your needs.

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.

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.

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’ve just upgraded to this TP-Link Deco BE3600 mesh system. I’m not tech savvy at all, so I was a bit worried about setting it up, but I managed to get the whole thing running in less than 30 minutes. It was dead easy to do. Why it's spot on: Separate Networks: It’s great because you can set up different SSIDs for your gadgets. I've got an MLO one specifically for my newer WiFi 7 devices to get the best speeds. No More Buffering: I set up a dedicated 5GHz network just for things like my Firestick. Since doing that, I’ve had zero buffering, which has been a total game changer for watching telly. Smart Home Friendly: I’ve also got an IoT network running on 2.4GHz for all the smaller bits like my doorbell and smart bulbs. It keeps them all connected without slowing down my main gear. Great Coverage: Because it's a 3-pack mesh system, the signal reaches everywhere in the house without any dropouts. Verdict: If you're looking for a way to sort out your home internet without a headache, this is the one. It's fast, easy to set up, and being able to split the devices onto their own networks has made everything run much smoother. Definitely worth the money.

So a Family member had this in his 3 storey house and I was impressed when I visited over a 4 day period. Before the TP-link S4 install I had a Virgin Media 350 and Super Hub 3, Split WIFI into a slow 2.4ghz and a fast 5ghz in the main house, a Apple Airport AP in the Garage on a separate SSID and an BT extension WIFI plugin in the Kitchen. (The BT extension was failing often and slow so that's going back anyway) Albeit I had 4 SSID's in the house. It worked fine but the 2.4Ghz was painfully slow in the extremes of our 3 bedroom semi detach house giving just 5-15mbps. So my issue was also I have a lot of 2.4ghz smart devices, Amazon echoes, Tplink Light bulbs, Kasa Smart plugs, all fighting for 2.4ghz bandwidth. I was worried that a joint MESH Wifi SSID may put devices onto this slow signal and I would have no option to swap it on the TP-link S4 app. Now the install: Simply swap the Virgin Superhub 3 to Modem mode via the login and then Ethernet connect the first Deco Unit and make it the router. This is done all on the superb Deco App, easy to install and then after an initial setup you simply add the other two units via WIFI first. Naming these Living room, Kitchen and Garage they were ready in 5 mins! Next I connected a TP-link 8 port non Managed Blue metal switch to the second ethernet port on the main router and this joined all my wired devices such as the TV and Game console, also ethernet extensions to the Garage for the Second Deco unit and to the kids bedroom PC's. (8 port switch around £25) The result? 3 Deco units. The main in the living room connected to a 8 port switch giving 32ping on gaming FPS shooters and online chat fully working (Nat type 2). The Second Deco in the Garage hard wired for a Ethernet backhaul to help with data and then the Third Deco connected via Wifi only in the Kitchen. The SSID? One simple name, one password, WPA2-AES (apple secure) security and speeds of 320Mbps in the Living room, followed by the slowest I could get in the house of 160Mbps! No more 5-15Mbps slow 2.4ghz. My iPhone Wifi App connects on the 5Ghz and runs super fast. The devices mesh the house very well, all my smart devices have so far connected to the 2.4ghz same single SSID and after 3 days I am a happy Dad with children not moaning and a WIFI that when the Wife facetimes her sister and walks around the house she doesn't have to switch the WIFI SSID or suffer WIFI cut outs! Worth the offer price of £99? Yes its worth more!. Easy to setup? Yes. It even had a firmware update and much like a famous mobile phone company it installed the update fast and without any issues within 5 mins with a countdown. I really hope this stays like this, I really hope that in a year or 5 years its still as good as day 1 because this is a number 1 winner. (As a note the S4 is very similar to the M4 and offers 1GB ports, however the E4 has slower 100mb ports) Hats off to Tp-Link, I have used some of their extenders in the past and they have been rather poor, this is the complete opposite. Superb .... so far. (Note: We live in a 1978, 3 bedroom Semi detach house with brick walls inside and an attached garage. I might have gotten away with 2 Decos, but at this price why?) Cheers All

Bought this as an upgrade to my previous TP Link Deco system. Installation was very easy and created my mesh network to replicate my previous one. Speed is a massive improvement and also the range this kit covers has also increased which is very welcome. I have absolutely no drop out anywhere I need wifi so I'm happy. Totally secure and it gives reports on how its being used and what's connected. Connectivity is great and the User Interface is easy to scroll through. This is a massive improvement over my last kit and I also think its value for money.

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

Internet reaches everywhere. Very easy set up

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.

very good speed
