    Simple to setup and use, great coverage. A good buy.

    To understand why we changed out our old system for TP-Link Deco WiFi 6 Mesh WiFi System will help.TLDR: Even with a two-year-old AC WiFi router, we had spotty coverage, dropped signals, added an internet extender, changed channels, and it still was irritating. Bought the Deco X20 system and it has been great with full, fast WiFi everywhere.We had a decent, two-year-old, brand name, AC WiFi router before these TP-Link mesh routers, but it could not cover the whole house in WiFi. Working from home or wanting to use a tablet in a bedroom or the basement just accented the existing issues.In our n

    I couldn't be happier with my choice! Setup easy, app really good, Ethernet backbone is killer

    I'm an IT geek / software developer for a living. I know all about how this stuff works and I wanted fast, but I didn't need crazy expensive for my home and some of these mesh systems are way overpriced IMHO. Reality is you can have all the latest crazy standards but once you get 20ft from the access point all bets are off and you'll never see the speeds you see quoted so you need to mix practical with price. There seem to be sooo many mesh system options these days, that I was overwhelmed, but after some consideration I thought I would just go for this one which seemed reasonably priced, but

    Decos x20

    So far I’ve been using them for 2 years.Pros: they are very easy to set up, great quality, they do not drop connection, very stable internet as long as you set them up right, the app allows you to label them, they work fine for connection up to 1Gb. Make sure you connect your main to your modern near an open space centralized and with an Ethernet cable cat 5 or higher. Each has a duel Internet port in case you want to hardwire into a device instead of wife. Cons: the app sometimes prevents them from working properly so sometimes you simply have to open up the app so it can reboot itself, after

    Works well, but some unexpected issues.

    I purchased this mesh system to supplant/reinforce an AT&T Arris BGW 210 modem/router so I would have better coverage. The system was easy to install, once I got the TP-Link Deco app installed and an account set up, and I connected it directly to one of the gigabit ports on the router. (It's located about ten feet away from the router.) I set it for access point operation. I also connected one of the other units directly to a gigabit switch at the other end of the house that is directly wired to the AT&T router.Coverage is great and I have a strong signal throughout the house.

    Tp-Link Deco X20

    This Tp-Link X20 mesh Wi-Fi device is a must-have if you suffer from dead spots or a lot of buffering Wi-Fi. It literally increased my signal strength and boosted up my mpbs almost threefold and that is no joke. The price here on Amazon is amazing and let's put it this way this device on the box claims it will do a 5-6 bedroom house and it definitely will. I only have a three-bedroom house and this device can definitely work for a house almost twice my size. I have included pictures The first one that shows an HDTV is from the TP link app running speed on average which is definitely good enoug

    Deco X20 (3-pack) = High-Efficiency (HE), High-Value!

    Our Installation: We subscribe to a 800 Mbps Comcast plan which actually tests at 900 Mbps. Our 1975 tinker toy construction (drywall/plywood) L-Shaped, single-story ranch 2300 sqft home has a crawl space under the footprint with an attached 3 car garage and backyard patio/swimming pool area.The 5800 sqft wi-fi coverage (overall average wi-fi data rates = 500 Mbps includes smartphones) is more than adequate for our needs (no gaming, 2 TVs (family room and garage) with 5 Alexa Plus/Echo Dots, roaming smartphones/GEN 6 laptop, desktop, multiple switches/plugs, Xfinity/Comcast owned Home Security

    Whole House Coverage That Actually Means Whole House

    Dead zones are a special kind of frustration. That one corner of the house where your video call freezes, the back bedroom where streaming buffers every few minutes, the garage where your phone gives up entirely. The Deco X20 exists to solve exactly that problem and it does so with a minimum of fuss.Setup is where this system immediately earns goodwill. The Deco app walks you through everything in plain language and the whole network was up and running in under fifteen minutes, which for networking hardware is practically unheard of. No cryptic router menus, no digging through settings pages t

    Helped save me so much money on my Internet bill, I actually profited

    You will not regret this choice. Having a reliable mesh system circumvents the need to pay outrageous prices for internet speeds that nobody on earth actually needs. Believe it or not, but you probably don't need more than 100Mbps in your entire home and this device allows you to better utilize every last drop of it.After doing much research, I figured my WiFi needs would be met with the absolutely lowest Spectrum tier of 100Mbps, but a much router or mesh system as the problem was not the theoretical download speeds but the quality of connection. Having a mesh system would allow me to downgra
