Excellent coverage and good roaming

I bought this product because it was among the cheapest options that includes Fast Roaming, which is to say your device can quickly switch between hotspots. This is important to me since there's no cell service where I live, and when walking from one side of the house to the other, my phone would frequently drop calls over wifi. Once I bought this setup, I have had no issues -- everything works perfectly. Easy to set up and manage.

Awesome! Returned a previously purchased router (no name mentioned), which did not have enough coverage and purchased this one and it is amazing. Thank you.

So Far So Great

I purchased this system this week because the router that I had was around 8 years old and I figured it was time for a change. In addition there were a few annoying dead spots around our house that I wanted to get rid of.I focused my search on the new 'mesh' systems since they are reported to minimize those dead spots. I did some research using a few different sources online and found that T-Link was one of the best reviewed systems and found that the Deco 9 specifically was indicated for 'thick walls'. We live in a fairly new 4000sqft house with steel beams and multiple levels which seemed to have limited our old router. Given that this system is indicated for houses up to 6000sqft houses I thought that it might be overkill, but thought better to buy too much than run into the same issue that I was having. In addition this system is reported to use the houses existing wiring as a "belt and suspenders" form of communication between the base units secondary to wireless signals.Upon receiving and unboxing the system, the set up was a breeze with the app that I downloaded on my phone. The primary unit is in my basement which is where the internet and modem is located. The other two units are on the main living level and were set up very quickly with no issues.We have been living with the system for 4 or 5 days now and all of the dead spots from the previous router are gone. The signal in general is much stronger throughout the house and everything is running noticeably faster.I would expect our experience to remain very positive and we are very pleased with our choice. Would highly recommend.

Great system, my review has actual numbers in it.

Have a ranch house with a full finished basement, 2700 sq feet. Suddenlink router is in the northwest corner of main floor, home theater and laptop are in southeast corner of basement. Wifi was very bad down there using the wifi signal put out by the router, so I put in a powerline system a couple of years ago, but it recently shot craps.I had never used a mesh system before, decided to try this one, bought and Installed it a month and a half ago. Easy to get running and it performs flawlessly. I plugged in one of the three units in the outlet next to the router, put a second unit on the same floor in the living room, and the 3rd unit is plugged into the outlet in the southeast corner of the basement.Most reviews don't seem to give stats, but I think they are valuable. Doing an internet speed test on my desktop that is directly connected to the router via ethernet, I am getting around 100 mbps. Doing a speed test on my laptop in the basement by connecting to the network via wifi, I am now getting about 50 mbps. And if I connect my laptop via ethernet to the mesh unit that is plugged into the outlet in the basement, I am getting 90 mbps....only 10 less than a direct connection to the router.Clearly my experience with this system has been outstanding.

Finally WiFi that doesn't feel compromised

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 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 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 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 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, 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!
