Review: WIFI everywhere in my house now! - 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 desertcart, 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!
Review: Strong Performance and Stability—When Configured Correctly - 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.

## Questions & Answers

**Q: I have to-link  1750 with extender is this a better setup ?? Cause every once in awhile the extender loss singl.**
A: Extenders will definitely allow connections from further away, BUT they always cut your speed exactly in half. So an extender is just that a range extender, not a speed increaser, it decreases speed.  However the range extension can prevent dropouts so it acts like it is a speed increase but it is really just preventing dropouts (and remember it always cuts your speed in half).
On the other hand a Mesh system is actually 2 (or more) routers that you place in 2 different spots and so it does NOT start by cutting your speed in half. It is full speed. But since your computer (or wifi TV or doorbell etc) is closer to one of the 2 (or more) mesh spots it will also extend your range for that reason, and prevent dropouts for that reason. And the closer your device (computer, laptop, etc) is to the router, the chances are the faster the internet speed could very well be (for instance on the ookla online speed test website).

BUT an extender works with your old router. A mesh system IS a router (actually it is 2 or 3 or more routers), so it will not work with your old router. The routers are built in to the mesh system.  With an extender you need a router (your old one for instance), the extender(s), and a modem.

With a mesh system you just need the mesh system and a modem. You do not need a router (because it is built in).

**Q: how far from the base can a node be placed and does each node have to talk to the base or do they talk to one another in a chain?**
A: The nodes talk to each other to form the mesh network.  The setup app will guide you in the placement of each node.  My base is in one corner of the downstairs, I placed one node in the kitchen which is in the middle of the house and the other node upstairs.  That gave me great coverage everywhere in the house.

**Q: I just installed this and apple is indicating wpa/wpa2 (tkip) is not considered secure. how can i configure this to wpa2 (aes) or wpa3 security type?**
A: Hi! The security message you are receiving is due to a recent update of your smartphone’s mobile operating system. To remedy this message and to make sure your Deco S4’s encryption is optimally configured, please ensure your Deco app is fully updated, then update the firmware of your Deco S4. Once the firmware has been updated, the Deco S4’s WiFi encryption will be set to WPA2-PSK [AES] by default, so this message will no longer appear. 

For detailed instructions on how to update your Deco’s firmware, please visit FAQ 1599 on our official TP-Link website. To locate this FAQ, visit our website and enter 1599 in the top-right search field, then click the corresponding FAQ in the search results.

**Q: How reliable and user friendly are the parental controls?**
A: The Parental Controls feature on our Deco Mesh WiFi systems is designed to provide robust, yet intuitive and convenient features to help safeguard your network and those who use it.

### ⭐⭐⭐⭐⭐ Finally WiFi that doesn't feel compromised
*by A***O on June 13, 2020*

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!
