Excellent boost in WiFi signal everywhere

Reviewed in the United States on June 30, 2024

Style: 3-5 Bedrooms 3-PackVerified Purchase

TL;DR I got 3 of these, I'm getting 2-4x speeds and 2x the range.

Just received and installed this today. From opening it up to testing the internet, it took all about 3 minutes each unit (I got the 3-pack). The instructions couldn't be any clearer and easier. Just install the app while you still got internet and you're set.

The three units are set up around a 4 bed, 3500 square ft single story home, total property has 0.8 acres. The first unit is set up next to the modem, one unit set up in the kitchen, and one unit in the detached guest room. Previously, my download speeds in my room, which is on the other side of the house from the room with the router, was about 3-5 Mbps on good days, online gaming was not an option and videos would take a quality hit. Now, I am getting easily 10-12 Mbps, and anywhere between 2-4x the speeds. I was blown away when I first saw it, I couldn't believe that my internet could achieve these speeds.

The range is now covering all the way from the mailbox at the start of our very long driveway, which is almost 200 feet from the router. I can watch videos on my phone anywhere on my property now.

I'd almost say I want to get more, but these things work so well I don't need any! Definitely will consider getting an upgraded model in the future, but these things are awesome for the time being. Excellent product.

IMO Review

FAST, simple setup, cheap mesh solution

Reviewed in the United States on January 22, 2021

Style: 3-5 Bedrooms 3-PackVerified Purchase

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.

Great product, but has some issues

Reviewed in the United States on July 1, 2020

Style: 3-5 Bedrooms 3-PackVerified Purchase

*** 1 Year Review Update ***

I decided to keep the system. After a few firmware updates and once TP-Link fixed the AP only mode such that the main and guest networks are truly separated I switched over from using it as a router to an AP solution. It has worked flawlessly since and without any performance degradation's.

I still do not like the app-centric approach for "management" (cannot call it that honestly); insight would probably be more appropriate. But, I will be moving in the future to an enterprise grade solution (this solution purchase has just been a stop-gap until that time and I finalize my network architecture). For the average home consumer that is not very tech-savvy (which is the audience this product really targets) it is overall very simple to get up and running with very few issues, especially at this price point.

I have submitted over a dozen feature requests to TP-Link and almost all of them have been discarded by the manufacturer (but at least acknowledged); of the ones that were "accepted" they were very trivial.

As of today, Sep 21 20201, the system via the app is no longer able to check for updates (it receives an error). I believe this is not due to the units themselves but instead TP-Link's update portal that the units use to check for updates. Checking on the main site reveals an update published on July 15 2021 (S4 2.0_en_1.5.0 Build 20210607 Rel. 56436_US_EU_AU_JP_up.bin) that is available which is one update newer than my currently applied firmware published on September 30 2020 (S4 2.0_en_1.4.3 Build 20200918 Rel. 77820_US_EU_AU_JP_up.bin). Looks like I will have to update the units manually using the download links provided by TP-Link and by logging into the web UI (note: each unit will have its own web UI but one - the master - will show a different one by showing you the topology of the mesh; a manual firmward update can be applied using that unit).

= Summary

Overall this is a great product. It definitely addresses the WiFi coverage in our new home. It has only been a few days since I set them up. However, a star in my rating had to be knocked off which will become evident shortly. I may update this review after some more time has passed. But it is currently appearing I might be returning this.

I operate these in access point mode and not router mode. I have a better router than what these units provide and do not need double NAT'ing on my house wide network. That, and, I will be replacing the house wide router with a substantially better one anyway in the coming months.

This review, however, covers my utilization and experience in both modes. Also note that I am an IT professional and deal with network infrastructure (along with many other things) day to day for over 20 years.

In this review the term “satellite” is used to denote a Deco unit that is not the main Deco unit.

I have intentionally saved the worst points of my review as the last section.

= Topology Setup

I have fiber to the premise gateway, still with the gateways’ Wi-Fi fully enabled on both 2.4Ghz and 5Ghz bands. My home is over 2,650 sqft, single story, built this year, with gigabit Cat5e cables to each room the Deco S4 units are situated. All Deco units use the Ethernet backhaul. All Cat5e runs and cables have been tested to support gigabit speeds point-to-point (with of course the obligatory TCP/IP overhead). Placement wise each of the Deco units are almost in a straight line, a function of my floor plan and where I need Wi-Fi coverage the most. Relative distances between Deco units:

- 25 linear feet between first satellite and second, main Deco unit with one interior door between. This I refer to as satellite 1.
- 45 linear feet between second satellite and main Deco unit with 3 interior only walls between. This I refer to as satellite 2.

= Performance

The throughput performance on these is fantastic, especially at the price point. I have fiber gigabit Internet service. I use speedtest.net for all bench marks. I get the following throughput on a Samsung Galaxy Note 8 (US), stock firmware, latest software and security patches. Distance is always the distance between my test device and a specific Deco unit and with line of sight between the test device and the target Deco unit.

| Deco | Distance | Downstream | Upstream |
Satellite 1 | 1 ft | 344 | 392 |
Main | 1 ft | 446 | 389 |
Satellite 2 | 1 ft | 460 | 392 |
Satellite 1 | 3 ft | 279 | 422 |
Main | 3 ft | 485 | 409 |
Satellite 2 | 3 ft | 392 | 383 |
Satellite 1 | 6 ft | 355 | 350 |
Main | 6 ft | 477 | 390 |
Satellite 2 | 6 ft | 483 | 461 |
Satellite 1 | 9 ft | 361 | 475 |
Main | 9 ft | 482 | 374 |
Satellite 2 | 9 ft | 477 | 466 |
Satellite 1 | 12 ft | 385 | 460 |
Main | 12 ft | 451 | 458 |
Satellite 2 | 12 ft | 501 | 528 |
Satellite 1 | 15 ft | 445 | 389 |
Main | 15 ft | 461 | 453 |
Satellite 2 | 15 ft | 500 | 432 |

A 15 foot distance between a Deco unit and a connected device is most likely acceptable considering average housing room sizes. However, in my house floor plan, I have an easy 25 foot line of sight from the main Deco unit to where I did a test. Results came in as 251 Mbps downstream and 117 Mbps upstream. Still, highly acceptable. At my maximum floor plan range to that same Deco unit and still maintaining line of sight of 33 feet I wind up getting an unexpectedly impressive 493 Mbps downstream and 388 Mbps upstream. While I cannot check in the app to see specifically which Deco unit my test device was connected to due to either app or overall product system issues, I am left with only one avenue of explanation: the Deco system has successfully performed link aggregation for my test device. If, in the first place, I am correct in this very poor conclusion due to the lack of data, then, this is indeed impressive and can very well be THE single most discriminator in overall product performance vs issues vs cost.

I realize these performance tests are not representative of real world scenarios. Fact is, most people do not go to such lengths to test their products and relevant environments, much less describe their environments.
When a little more time goes by I will update this review with more realistic real world performance tests in terms of longer distances and obstructions.

= The Good

I do not need parental controls, so, access point mode removes that for me, thankfully. Because I operate this in access point mode not having quality of service on the Deco's is just fine as is not having DHCP handled by the Deco's. Again, my current infrastructure handles all of these elegantly and more than sufficiently.

In order to get a proper pass off while going from one end of the house to the other I had to enable fast roaming. Without enabling this resulting in unbearably long hand offs from one unit to the other based on proximity to units. The net result of this was severe performance degradation. This seems to work without issue and solved the hand off issue.

The app is straightforward to use and easy to understand, ranging from initial installation to adding additional Deco's to day to day activities. The app also provides notifications of new devices when they are added to / detected on the network (both in router and access point modes).

As expected you can define a main Wi-Fi network and a guest network. This is standard fare. You can select if you want both 2.4GHz and 5GHz bands active or be more selective. Again, this is standard fare.

You can rename connected devices in the app. Useful especially when connected devices do not allow you to set their DHCP host name. The units try to profile a connected device type (e.g., Phone, PC, etc) in which the result of this is also easily accessible via the app. But, when it cannot or gets it wrong you can override this in the app, very useful feature indeed. The app will also show you basic information such as allocated IP address, MAC address (wish it was in colon delimited notation and not hypen as the former is the standard representation for MAC addresses), connection type (main or guest network and frequency band) and which Deco unit the device is currently linked to.

Unfortunately you cannot get the same level of information regarding devices connected to the guest network. Having visibility into this is just as important to give you another data point in your connected IoT devices. Oh, yeah, I suppose that people visiting your home is good too. Regardless, it is utterly unclear whether or not connected devices on the guest network have visibility to one another (e.g., can see each other), and much less have any reach into the main Wi-Fi or rest of your network. At a minimum, the default of any guest Wi-Fi network should be nothing can see anything else on the guest Wi-Fi , cannot see the main Wi-Fi, cannot see the rest of your network and can only see the Internet.

Any Deco unit can serve as the main. In router mode, this means that the main unit has routing capabilities. Likewise, a different unit can be specified as the main via the app.

= The Bad

There is no white listing of devices, only a black list. Security best practice is white listing devices that are authorized for access. Having only a black list is unacceptable. It is on this ground alone these units may very well be returned. It escapes me why TP-Link would fail to include the ability to white list. Since this product seems to be targeted to the less network technologically bound than myself I can understand why only a black list is available (to prevent the less technologically adept folks from effectively locking themselves out). However, not including a white list capability does an injustice to everyone and is, security wise, shameful and puts consumers’ home networks at additional unnecessary risk of exploitation. Yes, using a white list to winds up meaning having to go through a little more trouble to allow a new device onto the network. For me, and every other IT security professional out there, white listing is an essential tool in the security posture arsenal and is one that should never be omitted.

The only firmware release is the initial firmware release: Deco S4(US)_V2_191023 from December 25, 2019 (TP-Link support site). In the Deco app it reports no new updates for the firmware with a current version of 1.1.5 Build 20191023 Rel. 67285. Unzipping the firmware release on the support site shows the same firmware version as the app shows (specifically: S4 2.0_en_1.1.5 Build 20191023 Rel. 67285_US_EU_AU_JP_up.bin). Half a year later I would expect at least an additional firmware release. While not having any could be a good thing, generally, this is never the case. There are always bugs and vulnerabilities in every piece of software, and, firmware is no exception. Clearly a firmware update is needed at least to add a white list feature.

There is a barely usable web UI for the Deco's beyond that of just using the Deco app. I have found a landing page for each Deco connected to my router via the IP assigned to each. All UI's require authentication. The UI is different depending on which Deco you connect to. The Deco's that are not the main Deco provide the following features: update the firmware, pull the system log or reboot. Accessing the system log allows you to save it, email it or clear it. In contrast, connecting to the UI for the main Deco yields a subset of the features compared to the app but adds visibility into the units' CPU and memory usage. Said subset of features are mainly read only via the interface, again, not very useful. Thus there is no real point in using anything but the app if one is looking for access to more robust features.

Connected device presence status (online / offline) is wholly inaccurate as reported by the app. The only connected devices that are accurately reported for presence are those that have not left the Wi-Fi range and not power cycled. For example, all of my Fire TV sticks show as being online but all mobile devices that left the Wi-Fi range now show as offline despite being back within Wi-Fi range of the units for several hours. Even manually refreshing the view still yields in the app reporting these same mobile devices as being offline. More testing still needs to be performed, but, there is no reason why the device list status page in the app is this inaccurate.

Bandwidth utilization by connected device in the device list is great to have. The only problem is that it too is completely inaccurate to the same degree as mentioned previously regarding connected device presence status. For those devices that actually show as being online the bandwidth utilization shown in this same view is always 0Kbps up and downstream. Since installation of the units I have yet to see this populated and have seen, once, and only once, a single connected device bandwidth utilization being reported if I select the said device in the list.

There is no ability to perform a wireless site survey.

There is no ability to use 802.11x.

From a network management perspective there is no way to rename a specific Deco in terms of the host name that it will present to the rest of your network. All units show up simply as "deco-S4" from DHCP. Not useful.
There is no way to designate the guest network LAN IP address range.

= The Ugly

Initial set up was in router mode, the default. Setup of main and satellite 1 Deco’s went flawlessly and took but a few minutes per. Meanwhile, satellite 2 refuses to join the mesh in router mode and always leaves me staring at a red blinking light. The app reports “Unable to add these Decos” and “Move these Decos closer to a Deco that you’ve already set up, then tap TRY AGAIN.” Why would anyone have to move a Deco unit closer to another? They have an Ethernet backhaul, and by definition, can communicate with each other!

Meanwhile, the engineer within me takes a different stance: while all Deco units indeed have a gigabit Ethernet backhaul each unit must be able to verify a minimal Wi-Fi signal level from its closest neighbor. And, since I am a customer facing type of person that voice inside of me would scream: in order to assure the best possible experience please ensure all Deco units have no physical obstructions between them and that none are surrounded by things that can block radio frequencies such as metal and concrete.

Point is, I have yet to get all three Deco units online in router mode at all. It is NOT an option to bring any units closer together. Satellite 2 Deco has been power cycled and reset (via the reset button on the bottom of the unit) half a dozen times per with precisely the same results.

Now, putting the system into access point mode results in a perfectly usable system without any of these problems. Wish I knew why. Regardless, this is a telltale sign to me of poor engineering. Of course, switching system modes from router to access point (or vice versa) results in the system rebooting all Deco’s. The majority of most modern residential Wi-Fi capable routers do not require a reboot when making this change.

This is so problematic that it is cause, alone, for me to return the product.

Had alot of issues with loosing connection every often. Tried expensive Gaming routers did not make any difference as they are good up to one floor I believe.
I have couple out door cameras and doorbell camra and had issues connecting to them.
Kids were complaining for online school.
After doing a lot of research i make up my mind for Netgear mesh system or TPlink Deco.
I was already using Netgear router and extender and i love there products.
Also i am fan of TP link as well for very long time and used there products as well.
A friend of mine at work recommended me TPlink deco as well.
Right after installation everything started working fine with full speed and never lost connection, apart of the usual Bandwidth throttling in the evening or weekends.
Switching from 75mb cable to 300mb hi speeds internet.
Very satisfied so far and will recommend this to anyone who lives in a house with 4 bedrooms with over 60 devices or more. (Supports up to 200 devices).
Installed the units in the first floor cross the two corners on the first floor and it covers the whole house back and front and all 4 bedrooms with no more connections issues.
Buy it for piece of mind.
The other good thing is that Amazon automatically charge me 12 equal payments for another piece of mind.
Thanks Amazon and TPlink.

Finally, a fast and reliable mesh Wifi

Reviewed in Canada on January 26, 2022

Style: Tri-Band AX6600, 2-PackVerified Purchase

I've had Google Wifi (slow) and Netgear Orbi RBK50 (unstable) and now this Deco X90. While this is the first Wifi 6 that I have had, 99% of my devices are on Wifi 5.

Simply put, it took less than 5 minutes to setup and the speeds I am getting throughout my whole house are faster than I have ever had with other systems. It hasn't slowed down or needed a reboot since I powered it up. I'd recommend this to anyone that wants a simple to setup, reliable and fast mesh system. There are no dead spots at all in my 2,700 sq ft home and I got two units on my main floor at opposite ends. I have never seen any device with less than "Excellent" wifi connections since hooking this up. This includes devices on upper and lower floors.

The app is great too. A little lacking in features but for regular users it's perfect.

I will circle back to this review if anything changes but so far so good.
