About This Product

Deco M4 is the simplest way to guarantee a strong Wi-Fi signal in every corner of your home up to 5,500 sq. ft. (3-pack).[1] Wireless connections and optional Ethernet backhaul work together to link Deco units, providing even faster network speeds and truly seamless coverage. Simply add another Deco.


  • Deco uses multiple units working together to provide your whole home with fast, uninterrupted WiFi coverage.
  • The Deco M4 three-pack delivers WiFi to an area of up to 5,500 square feet. And if that's not enough, simply add more Deco units anytime to increase coverage.[1]
  • Plug a Deco unit into your modem, install the Deco app (available on Android and iOS) and follow in-app instructions for easy step-by-step setup.
  • TP-Link Mesh Technology allows Deco units to form a single network, organize WiFi traffic, and keep connected devices running at top speeds as you move around your house.[2] It also reroutes traffic if one of the Deco units loses power or experiences a disruption.
  • If one Deco is unplugged or experiences disruption, other units will route traffic for uninterrupted WiFi coverage.
  • Parental Controls allow you to create profiles for each family member, control how much time they spend online, and block inappropriate websites.
  • AC1200 dual-band WiFi ensures smooth gaming and streaming experience.[1]
  • MU-MIMO lets Deco units talk to several devices at once.[3]
  • Fast wired connections using two Gigabit Ethernet ports.
  • Disclaimers: [1] Maximum wireless transmission rates are the physical rates derived from IEEE Standard 802.11 specifications. Range and coverage specifications along with the number of connected devices were defined according to test results under normal usage conditions. Actual wireless transmission rate, wireless coverage, and number of connected devices are not guaranteed, and will vary as a result of 1) environmental factors, including building materials, physical objects and obstacles, 2) network conditions, including local interference, volume and density of traffic, product location, network complexity, and network overhead and 3) client limitations, including rated performance, location, connection quality, and client condition. Actual network speed may be limited by the rate of the product's Ethernet WAN or LAN port, the rate supported by the network cable, Internet service provider factors, and other environmental conditions.
  • Disclaimers: [2] Seamless roaming/No-Drop Wi-Fi refers to the Wi-Fi roaming that supports IEEE 802.11 k/v/r protocol, helping connected devices search and shift from one AP to another within 0.3 second. Clients need to support 802.11 k/v/r and may require additional setup. Performance may vary depending on the client device.
  • Disclaimers: [3] MU-MIMO capability requires client devices that also support MU-MIMO.

      Q:is this wireless
      by|Nov 21, 2023
      1 Answer
      Answer This Question

      A:  Hi! Yes, this is a Wi-Fi Mesh System. The main Deco Mesh node must be connected to your existing Internet source (e.g., modem, ONT, gateway) via Ethernet cable, and must be powered using the included power adapters. The remaining Deco nodes can then connect via Mesh Wi-Fi; however, they also must be powered using the included power adapters.

          TP-LINK was working properly for 3 day, but now it’s stopped don’t accept resets and two stations stays with fix yellow light all time. I need to substitute but I’m living in Brazil and I put out the box. Probably I’ll go to Miami In next month, because I’m pilot. There are someone to help me?
          Response from TPLinkSupportMay 18, 2023
          It sounds like you might have a warranty claim. However, TP-Link does not have an international warranty policy and products can only be replaced in the country they were purchased in. If your system is a US product you can use our warranty process. After troubleshooting support can approve an RMA, but since you are not in the US the process would be.

          1. Confirm there is a valid warranty claim
          2. register the product on the US Warranty Portal
          3. RMA is approved by TP-Link
          4. Customer chooses standard RMA and provides an address in the Contiguous US (48 landlocked states)
          5. Customer ships the defective product to TP-Link.
          6. TP-Link ships the replacement to the US address provided.

          Being a pilot i am sure you are not in one spot very long. The whole process typically takes 2-3 weeks from the day the defective unit is shipped to when the replacement is received. This includes the transit time of both shipments and processing. tplink

          I am a first time user. Very easy to setup with the help of the app. It's been working just fine for more than 3 weeks. All shadow problems are gone. I've seen similar products costing two or three times more than this product. It's great on monitoring the network. You are always aware of what is connected and its activity. Constructive critique: The active "TP indicator light" is on top of the unit. Since the unit has to be near the ceiling it is very difficult to see the active light to make sure the unit is operating correctly. I placed two of them upside down to be able to see the active light always. They work fine upside down. I would suggest locating the light on the side or bottom on future models to be able to monitor them from below.

          Major security flaw due to insecure http (and not https) access to the main router admin page when accessed from a browser (not the app). As if this wasn't bad enough, the web page has a typo: "Enter the password of the ower ID to manage the Deco network:" And of course if you enter the password of the *owner* it will be sent over the network in plain text!

            Picked up the Google WiFi Mesh system initially and was very dissapointed. Frequently disconnected and had poor overall speed. After wasting hours trouble shooting and getting worthless answers from Google support, I decided to return and picked this TP-Link Deco M4. Couldn't be happier! Better app, faster performance, even easier to setup. Best of all, it is $70 less than Google. If your debating between the 2, don't. This is the Mesh system to get.

              The Deco Whole Home Mesh Wi-Fi System by TP-LInk 30-May-2019 The Deco Whole Home Mesh Wi-Fi System by TP-Link works GREAT! Prior to obtaining this system I was unable to recieve Wi-Fi in my pole barn. I often want to look something up while working on a project in my barn and I was always struggling with a faint Wi-Fi connection from my home next door to the barn. I installed this system and now have a strong Wi-Fi signal in the pole barn and the house. Setup was very easy and straight forward using the App downloaded from the QR code symbol in the instruction manual. The App walked me through the setup process and made the setup simple and easy. Before I knew it I had all three included towers set up and working correctly. I now have a strong Wi-Fi signal on the first, second and basement floor of my house and in my Pole Barn. At first I thought the small owners manual was going to be an issue. It is about half the size of a index card (Height and width). I did not think I was going to be able to read the instructions without a magnify glass. I then realized that I just had to scan the QR code on the first page and that the rest of the setup process was done via the step by step instructions on my IPhone. Supper easy! (System Requirements-Android 4.3 or later/IOS 9.0 or later). I have an older IPhone 6 Plus that worked fine. One other small thing was that I wanted to set up a Guest Network after I completed the initial set up. I quickly located directions in the HELP icon/section, which directed me to use the “MENU” link to locate the Wi-Fi icon. It is actually labeled “MORE” not “MENU”. But after realizing that it was supper easy to successfully set up the Guest Network password. I believe this Deco Whole House Mesh Wi-Fi System is going to make the Wi-Fi in my house much more reliable and enjoyable to use. So far everything is working flawlessly. I would definatly recommend this system to anyone looking to expand the Wi-Fi signal in thier house or on thier property. Once each tower is set up and working, the App asks if you want to add another tower. I believe you could extend the signal farther and farther with additional towers. I can now add a Wi-Fi thermostat (Raise the temp in the winter prior to going out there) and Stream DIY TV shows right in the barn (Have a Digital Anntenna now which does not recieve many channels).

              Wow, does this work! We recently bought a new, old 3 bedroom house and set our internet router in the center of the house which happens to be the family room/office. Unfortunately, there was no signal in one of the guest rooms and only a fair signal in the master bedroom. We played around with moving the router but always ended up with some crucial room having no signal. This product's whole purpose is to solve that problem and create a strong wi-fi throughout a house - up to 5,500 sq ft. in size. It actually works like it is supposed to. Each Deco unit comes with a small, plug-in power adapter. There is also one Ethernet cable for connecting one of the 3 identical Deco units to your existing wi-fi router. The other 2 Deco units can be placed anywhere in the house where you do not have a strong signal. Set-up is provided through an app that is available for download for both android and Apple OS devices. The app is actually easy to use, and takes you through set-up step by step. If this old technophobe can do it, anyone can. The Deco system creates one unified, dual-band wi-fi network that allows several wireless devices to connect at the same time and provides much higher than usual wi-fi speeds; the wi-fi signal from each unit is very, very strong.This is the latest wi-fi technology. A bonus: Deco is compatible with Alexa per the maker, tp-link. It took us less than an hour to set up this network and now we have strong wi-fi signals throughout our entire home. Strongly recommend this product.

              A great addition to any multilevel home where Wi-Fi struggles because of so many devices that depend on Wi-Fi to operate sufficiently. For me it eliminates drop outs and buffering.
