I have a similar issue to another buyer. My main deco, pretty much every day, shows a solid red light while the 2 satellites flash a red light. As far as I can tell everything still works as it should. I still have good wifi and the internet is still available, so I’m at a loss to understand why the red lights are on. If I reboot the deco’s the red lights go off for a few hours then come back on?

I was recommended to use a three pack of these as part of setting up Starlink internet. The coverage is very good. There is a strong signal 50 yards from the house. One unit failed after a few weeks and after an exchange of emails with Tech Support I was recommended to replace it. Amazon supplied a replacement next day and everything has been OK since then.

Very easy to set up and works well with TP-Link AB1200 powerline adaptors. I now have reliable and fast wifi all around the house and garden too. I kept a powerline Wi-Fi adapter for use on a detached garage and that connects works fine too. Not cheap but after years of slightly flaky virgin hub 3.0 and range extenders, wish I had sorted this years ago.

We were suffering with Wifi dead zones all over our house. Was recommended this product by my Internet provider and it has not disappointed. From set up to use, absolutely faultless. I highly recommend anyone to purchase the 3 boosters over the 2. The extra cost is with it 100% recommended.

This product is incredible, set up is easy through the deco app. Seamless connection across a property I’ve had problems with for years with thick walls and fire doors. The triband 2.4GHz, 5GHz and PLC work together instantly out the box.

I’ve tried standard wifi extenders and weaker mesh systems and standalone PLC and nothing has ever come close to the experience with these devices.

Could not reccomend more.

I was struggling with no wifi zones and very slow connection when I was using the virgin media modem as a router or even connected to range extenders. I purchased this system and it solved all my wifi issues at home, it works wonders! I’ve been using it for several months and no issues whatsoever. Even in the garden I can now stay connected with speeds above 400mbps on my iPhone, and this speed is even better on my notebook. Very happy with the product!

I live in a semi rural area and recently installed Starlink for much much faster and reliable internet. I heard other Starlink customers were using TP Link deco mesh so thought I’d try them, replacing a mismatch of routers in AP mode and wireless access points. My main connection to the Starlink router is wired and so are 3 out of 4 deco units.

Initially, I had trouble getting them to work as the app kept reporting the ethernet cable as being unplugged, even though it wasn’t. After some net trawling I found that the main deco needs to be directly connected to your modem. Mine went through a switch first, and that was causing the problem. Luckily, having ethernet cables in place already meant I could move the main deco unit to a direct connection with the router and use the network switch elsewhere.

Once this problem was solved I’m very pleased with the setup. The most noticeable thing is being able to walk the length of the house and stay connected seamlessly. (My house is long, so needs 4 decos in a chain for best performance).

I’m getting 50-60 mbps over WiFi and 150mbps if connected by ethernet cable. They look nice too and it’s very easy to add further units if needed.

No issues with installation, powerline worked no problem although ymmv depending on your homes wiring.

Great coverage throughout the house now, some places are not as fast as others on speed tests but in reality max speed is not needed everywhere. Don’t believe the marketing on fastest possible speeds and new wifi standards, you don’t need them unless you’re watching 4k video from multiple devices simultaneously under the stairs for some reason.

I have a big old house, which means you get a few dead spots so have used these to eliminate that.
They’re pretty compact and easy to set up, and tbh the range on just one of them seemed to be a big improvement on my last tp-link router I had, 100% better than your standard virgin router. I have two out of the three set up and link them with a cable for better speeds. (you can link them wirelessly though). They are working well and rarely get any internet issues if any.

Software wise: its simple to use and has some control features on it, not as many as my previous router, but you can set up guest networks, name devices and categorise them. You can add parental controls and group devices allowing times and access rights. I do like that you can get notifications when a device joins your network.

My only gripe with them really is the amount of ports (2) in the back of them. If you link the two together for faster performance, then both ports are used in the first deco and only one is spare in the second. Once my hive system is plugged in you can’t port in anything else. Probably not a big issue and you can get a switch box, but just another would have been useful.

For the price I got them for they’ve been a good solution, standards are changing all the time and these will no doubt be out of date now. I didn’t need 3 of these so if you’re house isn’t big you can just buy the single for a big improvement on your wifi coverage.

I love the design
I love the app that come with it.
I love the flexibility it gives me.
I love the ease of setup (when i was not playing around and followed the instructions it went right!)
Disappointed by the web interface and what you can do it. (not much)
Disappointed in the signal strength. (read below)
Disappointed by the 1g ethernet connection on back. Assumed they would be 2.5GB at least but no, only 1GB

I have a 3 bed 1900 (ish) iron-brick house. Although i picked it up everywhere (better than broadband supplied router with extenders) I still had low signal in the places i wanted it to be good. Even with 3 of them i found cold spots (not dead) where buffering happened and lag become noticeable. After 3 months of frustration and disappointment (where i considered sending them back) i decided to hit the credit card and by 3 more x60’s, that where on offer at the time (amazon flash deal).

So now i have 6 of them (probably could have done with 5), I’m happy as a pig in mud 🙂

Zero cold spots in the house and can still pick up signal from 20m away outside of house (neighbours must love me) so garden streaming/zoom/facetimes have been done without issues.
Speed is relative when compare to a bottle neck of a internet connection which is always going to be your slowest part unless you go to a 1gig link.

I’ve backboned 3 of them together as a test and found 2 of my 4/8 port switches didn’t work (HP and Netgear). Lucky enough I recently brought a tp-link gig 5port switch which did. lots of talk on internet about it but in the end its a “try and see” if yours works or not if your going to cable backbone them. But buy/budget for a new tp-link switch if you want to cable backbone from day one. Cable backbone’ing is automatic although you need to setup as wi-fi backbone first (which it does automatically during setup). Then connect up the ethernet from switch and the x60’s will do the rest by itself.

Be warned though , it’s not instant. Took mine 5-10min before it switched over to cable backbone. Might have been because I was confusing the hell out of it… plugging it in and then unplugging it, trying to figure out why the hell it didn’t switch over….

Overall i love it and cant really fault the devices directly. If you can cable them up, you save yourself a lot of money from the triband x90’s. have 42 devices (on last count) on the network and it not even registering as being taxed/ overworked…

Also if you have a modern (non-metal ore brick work) 3 should do you. If you do the expect to get a few more or the (sale pitched) more powerful and expensive x90’s (if your stuck on TP Link, other WIFI6 MESH systems are available…)

Also Also – TP-Link love and i mean really LOVE your “Network Optimisation” option. Who needs wifi sniffer and a IT networking degree / compta+ network, when you can push of a button on the deco app, which then sniffs and configures best channels for you x60’s for optimal performance, if it registers conflicting /noisy wifi channels. (i’ve tested this with a sniffer because i’m sad i know. It does exactly do what it says on the app button!).

This review relates to the TP-LINK Deco P9 Whole Home Powerline Mesh Wi-Fi System, up To 6000 Sq ft coverage. Amazon seems to clump all the reviews together for these type of devices, so to clarify it’s the P9.

I’ve been suffering slow patchy coverage and internet drop outs with my Virgin Media hub 3, connected to an Archer AC1900 router via powerline adapters. My Virgin router was upstairs in modem mode, and my Archer AC1900 router downstairs. This set up was less than satisfactory with a loss off internet speed as I move around the house and internet drop outs two or three times a day. This is a particular problem as I have Ring cameras that need a stable connection. My house is a sixties built larger than average semi with sound proofing in the walls and ceilings which adds to the problem.

I bought the TP-Link Deco P9 Powerline Mesh system in the Black Friday deal for 169.00. It was incredibly easy to set up. All I had to ensure was that my router was in modem mode (just a tick in a box when I logged into the admin page of my Virgin Hub 3). The Admin credentials were on a sticker on the bottom of the router. It will save you a bit of time if you download the Deco app first and create a TP-Link account. You’ll need this to set the TP-Link devices up from your phone. Once this was done I connected one P9 device to my Virgin Hub via an Amazon Basics Cat 6 Ethernet cable. The app walked me through set up which was just a case of connecting to the device and following the on screen instructions, and then changing the default SSID name and creating a new password. Once set up is complete it’s a short wait until the light on the top of the unit turns white and the unit is now operational. The first device was upstairs near the Virgin router, the other two units were placed downstairs. One in my back lounge where my TV is, and the other in my front dining room. I just plugged the other two in and they automatically connected, no more set up needed.

The devices are aesthetically pleasing and made of white plastic. Slightly taller than an Amazon Echo. They don’t look out of place on a table top or shelf. The plug is a standard UK 3 pin plug (for the UK version), which means that the powerline element must be built into the unit itself. This was welcome as it means the small form factor plug fits anywhere (rather than the bulky powerline plugs i’m used to). Each unit has two ethernet ports, for connecting to a router, or for connection between each other or to other devices. As these units use just a single SSID (which I created at set up), my devices connect to the strongest signal and see the Wi-Fi as one connection rather than three. This should mean seamless switching to the strongest signal, unlike extenders which create separate SSID’s. It also means that if one P9 goes down, your device can connect to the next available one.

With my placement of these devices, I’m now receiving 112 Mbps download and 12 Mbps upload speed in every room with my 100 Mbps Virgin Internet package. It also works at near full speed at the bottom of my garden which is impressive. The app is simple and doesn’t give you full control over the router, but does have some handy tools such as monthly reports, blacklists, parental controls (even being able to see internet pages visited by other phones or computers), high priority devices, adding managers, fast roaming (newer devices switch to the fastest connection quicker), and a few more settings.

I believe the powerline element of these are to enable ‘Backhaul’ communication. That is, communication from the three devices back to the router via your electrical wiring, so keeping the Wi-Fi less clogged with traffic. You can’t use the powerline feature to connect other powerline adapters. It’s a hidden network just for the three units to communicate. It also helps through thicker walls where Wi-Fi might be weak, to keep all the devices talking back to the router.

This has transformed the Wi-Fi in my house giving me fast full speed coverage everywhere. It has great flexibility for moving the devices around to test where they work best (all you need is a plug socket). Of course, if you can link these together via ethernet cable you’ll get the best connection. But for me, locating them on different floors and in different rooms, just plugging them into a power socket and using WiFi, they have been brilliant. Full speed everywhere and not one known drop out of internet so far. Highly recommended.
