After doing a lot of comparison shopping, I ended up settling on the TP-Link Deco S4. My biggest factors were price, reliability, and range. I have a three floor 4500 sq/ft house built in 2003. The Verizon Fios Gateway router worked, but it suffered considerable slow down as I got to the extremes of the house. With the new three node Deco S4, I get full speed internet at every floor and extreme. Previously, I was able to get 100mb/s maxed out at the router with minimal traffic, but dropped down to 10 mb/s at the extremes of the house, especially the basement and some bedrooms. With one of these on each floor (main on middle), I range from 95-120 upload and download (paying for 100) on all three floors depending on time of day. Interestingly enough, I haven't suffered much dropoff in signal strength with each mesh node as opposed to the main wired unit acting as the router. I've read countless time that unless I'm using a wired backhaul that there would be signal dropoff at the mesh points, but I haven't witnessed any significant drop. I also purchased this system as it had ethernet ports for backhaul (if I needed to improve speed) and accesspoint use on each node, but I don't use any other than one at the main router for my Phillips hue bridge.
The design is simple and clean. I was debating on saving $10 and getting the M4 (identical internals), but figured I was already scraping the barrel on price point so may as well get one that wasn't as much of an eye sore. These are clean, simple, modern, and much better to look at then the Fios provided router.
The app is simple and intuitive and makes most of the decisions for you. It ran me through the setup very easily. It has parental controls and allows me to prioritize devices as well as setting up a guest network. However, what was most essential to me was the ability to turn off 2.4 or 5ghz signals if I needed to set up a product that only worked on one (usually older products that use 2.4 only). This app is mostly for people that have basic technical skills, but not full on IT networking knowledge.
I chose to replace my Fios router entirely and run ethernet from the Verizon modem (optical network terminal) instead of coax so I didn't have to run the Fios router in bridge mode. I called Fios tech support and the person switched the feed to ethernet in five minutes. Now I don't have to rent my router and have much faster internet without relying on bridge mode. If you aren't comfortable with running ethernet and swapping it out at the ONT, you can use the Fios router and connect the Deco S4 to their router instead. This also allows you to keep your cable box functionality such as guide and on-demand without a MOCA adapter. I have no such plans as I'm dropping cable for YoutubeTV.
On average, my house has around 40 connected devices from Phillips hue bridge/bulbs, Ecobee thermostat, Ring products, several Nest and Echo devices, five smart TVs, smartphones, tablets, and laptops. Don't buy into the hype that you need wifi 6e. This supports gigabit+ speeds and the dualband is more then enough to maximize efficiency. In addition, you can add or swap out mesh points to this system at any time from any Deco system (E3, M4, M5, P9, etc.). You can literally improve on this system in the future if desired. This was one of the best purchases I've made in a while.
Update 2.4.21: I recently switched to 200mb/s from my ISP (it is the lowest package they offer when only purchasing internet). With this, I've noticed download speeds at the main router at 270-300 and 300+ upload depending on network traffic. I have seen more noticeable drop-off at the mesh points with this speed, usually 170-230 download and 200+ upload on my first mesh extension node, and 160-200 download on the one in the basement. I also have the biggest variance in upload speeds with this one at 45-120 upload, depending on time of day and network traffic. However this was also the location I had the biggest issue with previous to installing my Deco S4 system. In general, I am still getting amazing speeds, far exceeding what I'm supposedly paying for, extremely stable at every location of my house including the far extremes of my yard. I have can rely on blazing fast reliable internet throughout my house and not have to have wired backhaul to achieve it. However, I can now see why some individuals suffer noticeable drop-off with higher internet speeds at the mesh points. If you figure the drop-off as a percentage and multiply it times the speed, the difference will be more noticeable at the ghz speeds. Overall, love this device, how much faster my internet is and how I am not paying my ISP for their outdated routers they try to dish on unknowing consumers. Best purchase I've made in years.

Stupid easy to set up
Needed to cover a dead spot in my house.If you follow the directions EXACTLY, youcan be up and running within a half hour.I have 300 mbps FiOS service to my home router.Adding the TP link via a switch connected to myrouter and transmitting 20 feet through a ceiling/floor, speeds of 200 mbps symetrically are achieved!Once installed and operational, it’s just another secure background device

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!

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.Reviewed in the United States on June 13, 2020
