TP-Link Deco S4 Mesh AC1900 WiFi System, Deco S4(3-Pack)

The Deco S4 is a fantastic mesh Wi-Fi system. It’s easy to set up through the app, and adding devices is simple and intuitive. Wi-Fi speeds remain consistent as you move from room to room, and the system handles multiple devices smoothly. It’s also easy to configure passwords and create a Guest Network. Newer S4 units include additional features like an IoT network option and the ability to manually assign which satellite Deco connects to which primary node—super helpful for optimizing placement. IMPORTANT TIP for Ethernet Backhaul Users: If you plan to use Ethernet backhaul (which I highly recommend if your setup allows), do not connect your Decos through unmanaged switches. You must use managed switches with loop prevention (such as STP or RSTP) enabled in the switch’s settings. I ran into a host of frustrating issues when using unmanaged switches: The main Deco would lose internet when opening the TP-Link app Satellite Decos would randomly report as offline Firmware updates would fail or not even check properly Changes in the app wouldn’t apply Echo devices struggled to stay connected Network optimization scans would fail If a single Deco lost power, it could take hours to get the system working again After replacing my unmanaged switches with managed ones that had loop prevention enabled, all of those problems disappeared instantly. Summary: This is a powerful, reliable mesh system that performs exceptionally well—as long as it’s set up correctly, especially if you’re using Ethernet backhaul. TP-Link did a great job with the Deco S4, and I’d definitely recommend it to anyone looking for stable whole-home coverage. Just don’t overlook the importance of your networking hardware if you're wiring things in.

The Deco S4 Mesh system fixed the issue I was having with bad WIFI around my home. My Verizon fios router was constantly dropping WIFI, and even when it was working the WIFI speeds were horrible. This is unacceptable in todays world of everyone working and doing their school work from home. We needed a solution that was affordable and could cover our entire house with good strong WIFI. I searched a long time and finally found the Deco S4 Mesh system here on Amazon, and I am glad I did. I purchased the three router Deco S4 Mesh system for my 2000 square foot house as we have two floors, a full basement, a breezeway, a patio and a garage that I wanted to cover with WIFI. I have one S4 hard wired into the fios ONT in my basement via a Cat5 Ethernet cable, and the other two S4 routers are set up wirelessly. The hard wired S4 going to my computer is located at one end of the house on the first floor. One wireless S4 is in the basement, and the other wireless S4 is on the opposite side of the house on the first floor. The set-up was very easy, and the Deco app made connecting all three S4 routers quick and painless. Thankfully I get a decent cellular signal at my house, so I was able to set up the Deco S4 Mesh system using my cell phone. You have to remember that once you disconnect your existing internet from your old router, you can't use the Deco app unless you have a good cellular signal and a device like a cell phone or cell tablet to do the set up. One other thing I especially liked is that I could name the S4 network whatever I wanted. This makes it easier for me to remember what the network is called as I no longer have to remember the very long alpha-numeric name of the old router. This makes connecting devices much easier and a lot less painful. The only negative I would give the Deco S4 Mesh system is that there are only two Cat5 Ethernet connections on each S4 unit. I have three Ethernet connections at my computer and I had to re-route one connection to one of the other S4 units, but I did not deduct a star for this because I knew about this before I purchased the Deco S4 system. The whole S4 Mesh system took about 30 minutes to setup, and I now have super fast WIFI everywhere, even in my garage, back yard and shed! With this new Deco S4 setup, I am now getting the full upload and download speeds via WIFI that I get with the hard wired Ethernet connection to my computer. This never happened with the fios router, even when it was new. With everyone now in the house all day long working from home and doing school work, bad WIFI is NOT an option. The Deco S4 Mesh system solved all of the issues with poor WIFI we were getting from the fios router. I would highly recommend the S4 Mesh system to anyone, especially if you have problems with your current WIFI around your house. The other great thing about the Deco S4 Mesh system is that with more and more devices all needing to attach to a home network, it says it can handle up to 100 devices! My fios router, even when it was working, was having trouble keeping up with the devices we have. It is amazing how many things we have now that require a good WIFI network. There are Echo devices, smart outlets, smart switches, smart bulbs, camera's, cell phones, tablets, lap top computers and on and on. It did not take long for us to go beyond 50 or more devices in our home that need WIFI, and this Deco S4 Mesh system has been able to keep up with all of them! At last count, we now have 59 devices and there are more on the way I am sure!

Well, I've went back and forth for about a year now about setting up a mesh network in my home. Currently I run 3, so this would in a sense replace one. I like keeping certain aspects separate... security cameras, and system are on a dedicated network. Tvs, computers, laptops, tablets, and cell phones are on one, and then I start sounding like I have more money than I really do, so I'll just stop there... I decided to buy a mesh network to replace my security system network because I was having tons of issues with my outside security cameras having horrible signal strength which made it pretty much useless. Before this, I bought a CPE Booster, and honestly I had and have zero idea what exactly I was doing, needed to do, or was doing wrong. Long story short, I worked alot of Overtime, and literally within 5 minutes of my check hitting my bank account, I had this ordered. It was SAME DAY DELIVERY.... WOW. Unfortunately I was working several hours away at a prison job that is going so bad, you would think it was being performed in a prison..... wait... it was. After the extensively long work week, and driving several hours home, after working 10 hours that day already, all I wanted to do when I got home, was get this bad boy setup and configured... so the next morning when I woke up (lol), I immediately got to work... the app is extremely seamless to use. Theres not very much that I'd change. Setup was very intuitive and straightforward. I bought the 3 pack because honestly, a 2 pack would have worked for my small house, but I needed to get the signal outside to my garage that is anything but right next to my closest wall. I bought the 3 pack hoping I could intact put one of the units on the closest wall to the garage to get adequate signal. Thats exactly what happened,, and its been working great.. i have although noticed that my front door camera seems to have randomly dropped off of the client list on the app. Upon checking the camera. I find that its not connected. This has only happened once that was without a reasonable explanation... hopefully it was an anomaly. This has been perfect. Literally perfect. My cameras stream comes up within a couple seconds, and I can talk clearly to the person on the other side. Honestly, we are looking to be upgrading our home within the next year, and I can't wait to outfit it with another tplink mesh system... for the price point, you cannot go wrong. I want to add that I was in the corporate I.T. industry for 8 years... so quality in technology is a huge part of my decision processes when choosing what to buy. I've bought TP-link products in the past, but honestly I tend to give more of my hardware away than I use... this is the first product that I've actually dove deep into... I will be returning for my hardware networking needs in the future.

This is a nice solution for mesh wifi. However non technical users may have some difficulty setting this up unless they follow the directions very closely. Also you should search the web for the deco S4 product and review the information found there as well before buying. I actually set up my 3 S4 Deco mesh in access point mode. To do that I needed to first run through the app as if I were connecting the first deco to my DSL router but I did not, then I accessed the settings (under the More button on the bottom of the app) then the Advanced for the first deco and set the Operating mode to Access Point. After that setting up the other 2 was a breeze. as they automatically configured. The instructions from the app advise you to upgrade firmware for each deco if used as an accesspoint. The app prompts were easy to follow and this upgrade was easy to do. Next was the placement moment. I decided to connect my "Main Deco" (this is what the first one is named) through a ethernet cable from my DSL modem to another switch in my living room and then connected the deco to that gigabit switch. This worked great. Then I tried to connect the other two deco's using a ethernet powerline adapter however this did not work so well, at first I thought there was a problem but after experimentation I found that the best way to use these as access points is to direct wire the first deco and then use the other two wirelessly. That took off immediately and all mesh points worked fine. Wifi signal expectations. Your Deco that is direct connected to the DSL modem/router (in access point mode) will pull the same speed as your home wired connection (in my case about 67mb) the other wirelessly connected decos will pull in the High 30mb-45mb so you will expect to see about a 40% loss of bandwidth connecting as I did. However the wireless connected decos deliver a solid signal and I can still browse, and stream with multiple computers/ipads/TV's with no issue. Also I have ring cameras and their signal improved after the installation of these deco units. At first you may find many components connecting to your "main deco" but that seems to be related to the order that you power up the units. After about a day all my wifi connected components sought out the deco closest to them and connected to the mesh there. This is one nice feature about the app, it is easy to see what devices are connected to each deco. If you accidentally /(or on purpose) switch off the mesh feature for a device it will stay on the deco it is currently on. I thought I was going to have to do that but it does not seem to be an issue. I am considering running a wire to the remote units if at some point I increase my service from the 70mb it is currently at but at present everything is working fine. Regarding tech support, I did access the live chat of the tech support but they primarily feed you the same answers that you can get off the web or by reading the support pages. So I would not rate them too high, maybe 6 out of 10 for service. But they did respond and they did attempt to answer my questions. Another small point but one I like is that the LED's that show the unit state are not overly bright but they are easy to see and you can easily tell the state of the unit (yellow during reboot, Red if there is an issue, or Red blinks a few times before going to white which means its all good!) and are not distracting in anyway. The app could be a bit better, there are some not so intuitive points to it and you will need spend some time figuring it out. Overall I am quite happy with my purchase. Now I will run them for a while and if any significant discoveries pop up I will update this review.

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 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. UPDATE I've just deployed a smaller mesh network in my own home using the same S4 routers that I bought for my customer. While these routers are not the newest and fastest option available, they're very affordable and completely capable of handling modern network traffic. I regularly have 10+ devices connected at a time including several game consoles, and never have any issues with network speeds that could be blamed on the S4 Decos.

These are great. Pretty clear on how to set it up. Only issue is one constantly needs to be plugged into the router, didnt realize it, but no big deal. Easy to navigate, easy to monitor with the APP. Its a solid purchase.

I have Verizon FIOS bundled service, so I have my TV, phone and internet all-in-one. While I do love FIOS, one of the negatives is that I had to use their bundled Gateway modem/router because of my TV and phone services. My house does have a wired ethernet network running thru it, which is great for all my desktop PC's and Home Theater setup, but the FIOS Gateway router's WiFi performance didn't adequately cover my three floor house (the FIOS modem is in my garage, next to my home wired-network box). To help solve this issue, I tried using the very well reviewed Netgear EX6200 range extender, but I could never get reliable performance out of it...random drops, slow speeds...it just didn't seem to like working with my FIOS router. In looking for a better solution, my research led me to looking into Mesh networking, especially as these systems (supposedly) would not need to bypass my FIOS modem...it would work with it, just taking over the WiFi functions. I was apprehensive, so I wanted a cost effective product. Tp-Link's Deco series have gotten rave reviews and their latest S4-series was actually cheaper than the previous M4-series, so I took the plunge. Getting the Deco S4 up and running is so much simpler than traditional WiFi extenders and boosters...download the TP-Link mobile app, launch it, pick your TP-Link product and it guides you through the whole process. There were some hiccups during installation, mainly where the app failed in finding the S4 devices on the first pass, but hitting the Try Again button solved the issue. The S4 router unit (all three are identical) simply plugs into any open port on the back of the FIOS modem. Once the Mesh network is setup on this S4 router, you can now easily add the other units throughout your home using the app. The app has a lot of functionality...you can set-up usage profiles, "Blacklist" devices from using your network, monitor network health and utilization, etc. Two other benefits with the S4 Deco units are that each includes two auto-sensing Gigabit ethernet ports (useful for network switches/hubs or plugging in non-WiFi devices, etc.) and that they are compatible with all TP-Link WiFi devices, so expansion and upgrades are easy. Coverage is excellent. The big benefit to a Mesh network is that all the S4 units are essentially operating as one...so, as you move throughout your house (or even outside!), your devices simply pick-up the strongest signal from the best available S4 router. You don't need to manually switch from network to network like you would with a traditional WiFi extender. Speeds are surprisingly fast. I only have FIOS 100/100 service, but I am getting WiFi speeds of 100+ Mbps on my ground and third floors (both S4 units are wired) and almost a full 80 Mbps on my second floor with a non-wired S4 unit. Outside on my back deck, speed drops to "only" 60 Mbps...incredible! I spent about 4 hours stress testing the network and found it to be rock solid...very consistent and dependable WiFi performance. If there were two things I'd list as negatives, they would be the lack of a web-based network tool/programmer (everything has to be done on the mobile app) and that there was a way to identify/isolate usage between the 2.4 and 5.0 bands. This is a long review, but to sum it up, the Deco S4 is a great product. It's simple to set-up, works with your existing modem (a HUGE plus for Verizon FIOS users), doesn't act like a bottleneck and offers a huge area of coverage. And there's the very nice price. I finally feel like I'm getting all the WiFi I'm supposed to be getting!

Finally got rid of the dead zones in my house—WiFi stays strong in rooms that used to have weak or no signal. Setup was surprisingly easy, devices switch seamlessly between units as you move around the house, so there are no random disconnects. Handles multiple devices well, including phones, laptops, smart TVs, and smart home gadgets, coverage is impressive and works well for larger homes or multi-story layouts. Great value compared to many other mesh systems on the market. The only issue is that performance can vary depending on how far apart the units are placed!!

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.

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!

Siguiendo las instrucciones de de la App. el TP-link Deco se instala fácilmente. Una vez instalado funciona correctamente. Mediante una RED DE INVITADOS tienes bajo control las TVs, Tablets, teléfonos etc. lo cual es muy útil, pues algunos chicos abusan de la nueva tecnología digital.

My home has 3 floors, and this works so well. Setting up was a breeze. And it looks aesthetically nice as well!

Me encanto! Había probado antes con otros routers pero sin duda este fue el definitivo, fue muy muy fácil de instalar, pues en la aplicación te va diciendo paso por paso que hacer, ya llevo un mes y no he tenido problema de que se desconecte o desconfigure, me encanta saber que a donde me mueva dentro de mi casa pueda seguir conectada a la misma red sin tener que cambiarme a otra como con otros routers. En casa nos sirvio por que tenemos un patio algo grande y queríamos que cubriera la red hasta el otro extremo dónde hay un cuarto a dónde no llegaba la red. Vale mucho la pena si has batallado antes con otros routers.
