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

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 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!

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!

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.

Appareil livré avec des fiches électriques anglaises, et non compatibles avec le réseau électrique français. Afin de fonctionner ils nécessitent l'achat supplémentaire d'adaptateurs français. Cela N'EST PRECISE NUL PART, et tiens donc du DEFAUT D'INFORMATION ! Le vendeur m'a proposé un remboursement de 8€ pour équiper un boîtier, hors il en faudrait trois. En cas de retour les frais d'expéditions sont à la charge de l'acheteur, hors ces frais sont supérieurs à l'achat d'adaptateurs. QUEL MANQUE D'HONNETETE...

This set is awesome. We went from a 2br apartment to a large 5br house and needed more coverage than what was available with our last router. Setting this set up is a breeze. I plugged it directly into our NBN FTTP hookup in the house and was able to log in (with the help of my provider's customer service -- I would recommend calling them if you haven't already) and once I did, it came right up. It allows you to easily name and change your network name and password and for the creation of a guest network, if desired. Once the first was set up, I went upstairs and installed the second. It was even easier than the first. Not enough can be said about how convenient it is to have one signal that covers your entire house. I got to my parents' place who use repeaters and it can be a nightmare going from place to place around the house. You will not experience any drop in coverage, as it does exactly what it's advertised to do -- provide a wifi "mesh" throughout your home.
