This is a fantastic piece of kit
Having had a gable end extension to our house some years ago the old external 300mm thick wall became an internal wall that WiFi couldn’t penetrate.
Tried a so called WiFi extender/booster with poor results as the signal kept dropping out and was weak at best.
The TP link AV1300 is truly amazing.I just plugged it into our virgin hub 3 and in no time at all it set itself up without any paring or faffing about and with excellent speeds too
Highly recommended

Only have this item for a few weeks, but, so far, no problems. I gave it four stars simply I do not have it long enough to do a longer time review
I spent some time debating if a power line adapter would work for me. I have an office/shed in the garden, the electric cable is 50m from the main RCD consumer unit and the WIFI router is on a different ring circuit. There is no clear answer, some say it wont work, some say it will. Well I took a chance and well it works and from the brief time I have tested it it appears to be as fast as being on main router if browsing or watching a you tube video. Not yet tried any other load on it.
On setting it up, it wasn’t as straight forward as expected and finally worked out I had to log on to the website to find the password to connect on WIFI. A bit of a faff and could have been a bit easier if explained better in the instructions. But still was set up within an hour, even with my issues.
So if you were worried about connecting over different circuits, this one works.
Have had several power line adaptors each worked well initially. However performance tailed off over seveal months. This one TP-LINK AV1300 has worked well from start increasing my up load and down load speeds significantly. Its early days yet in terms of durability but at moment I am more than happy with performance
This transmitter and wifi receiver works perfectly for me, despite the transmitter and receiver being on completely different circuits in my house, and the receiver is in the garage at the end of the garden, going through about 100ft of 2.5mm cable! Nothing else has worked for me and I bought this expecting more disappointment, however I am happily surprised at how well this works, and I would recommend it to anyone experiencing problems getting internet signal to troublesome areas of your property. The setup could not have been simpler, plug both units in next to each other, press the WPS button on the router, wait a couple of minutes, then hey presto, I have WiFi signal wherever I plug this in. A bit pricey as I went for AC pass-through on both units as we don’t have many power sockets, but worth it to finally have WiFi in the garage and throughout the garden.
THIS TP LINK WORKED WITHOUT HAVING TO PAIR IT FIIRST, WHICH OFTEN TAKES TIME AND GOES WRONG A FEW TIMES. THI WAS PRE – PAIRED AND WE JUST PLUGGED IT IN AND THE WIFI WAS ON!
FANTASTIC!
These are THE BEST BOOSTERS EVER!!
I had these recommended having wasted money on rubbish ones previously. Definitely worth the money.
Simply put, you get a box you plug into your router which also plugs into the mains electricity.
You then have 3 boosters (like big plugs) that you plug around the house where signal is rubbish – because they go straight into your electricity, you just connect to whichever box is in that area of your house/office. That’s a non tech explanation lol! Plug, connect & go! SIMPLE
These are brilliant for my house as I have big thick walls & the router is opposite side of the house to my home office! As they plug direct into the sockets the signal shows as ‘excellent’ every time on every device & as I move around the house my phone picks up the different boosters automatically instead of dropping the connection. Great for video calls/facetime or music apps on your phone when you’re moving around. Very impressed, highly recommend 5
I really like that the passwords for each port are all numbers!
We stream TV, game and video conference using these. Very easy to configure, just press the pair buttons; more detailed configuration (which many might not need and there is a detailed user manual you can download from tp-link) using the web interface is self explanatory but I have more IT experience than is typical; you should bear this in mind if you are less experienced. The web interface offers great flexibility, crucially it offers the all important MAC address white listing (I won’t entertain any WiFi without this capability), for fun you can even schedule when the LEDs turn off at night which is actually useful in a bedroom. Find the web interface at the private IP address your broadband router assigns it, most likely starting ‘192.168’, or download the tpPLC utility from tp-link and access your device’s web interface via tpPLC by clicking on the little globe which pops out to the right of your device (give tpPLC a few minutes to sort itself out, then hover over your device and watch the globe pop out). Clicking the globe will open a browser at the appropriate IP address, the first time in you’ll need to set a device access password (this isn’t the SSID WiFi password). Each WiFi capable tp-link device will have a different IP address. The default device IP is provided by your router’s DHCP server but you can statically configure. The TL-WPA8631P also provides a DHCP server with configurable address range (you can disable it). The WiFi has WPA/WPA2/WPA3 security, 3 power levels, a guest network off by default, parental controls for specified MACs, 2.4GHz and/or 5GHz can be switched off. There’s facility to backup/restore settings, some settings can be synchronized (or not) across devices, you can list connected clients. I downloaded the user manual from tp-link to check it had the features I needed, it’s comprehensive and runs to about 45 pages.
My house has brick internal walls dating from mid 20th century and covers an area large enough to make WiFi difficult. The house wiring is approximately 15 years old, I have no ethernet cables between rooms, I rely on powerline data transmission using the house ring circuits. I find no problem running powerline devices on simple inexpensive extension leads (without power filtering) and somewhat surprisingly find these devices work between ring circuits; I don’t understand why this is but it’s likely because I don’t understand my house wiring well enough (it was rewired before I moved in). The takeaway is that in my house the powerline works very well everywhere, even in the ‘garden office’ which has its own ring circuit and is 60ft from the house, but it might not follow you will get the same performance; from what I read your house electrical wiring is critical to your experience.
I currently have four AV1000 (max 1000Mbps over powerline and with 1Gbps wired ethernet) and two AV1300 (max 1300Mbps over powerline with dual band wifi and 1Gbps wired ethernet). I downloaded the tpPLC utility from tp-link and run it on Windows 11; it shows the powerline speed being achieved between the various devices in my house is more or less half the max theoretical speed of the slowest device. Thus AV1300 to AV1300 is typically ~700Mbps, AV1300 to AV1000 is typically 400/500Mbps and AV1000 to AV1000 is also 400/500Mbps. The tpPLC utility shows these numbers vary over time over a small range. Whether these speeds are a realisable data rate for connected devices I don’t know, I assume there are loses and actual connection speeds for equipment will be slower. The broadband speed to my house over fibre is 130Mbps. Speed tests from computers to the internet using ethernet cable connected to the 1Gbps ports show me achieving 120/134Mbps so powerline isn’t causing a bottleneck and I’m seeing my full broadband speed. When I increase my broadband speed to 264Mbps it will be interesting to see if I see this greater speed over powerline. The AV1300 TL-WPA8631P offer 2.4GHz & 5GHz wifi. At 5Ghz I also achieve 120/134Mbps, at 2.4GHz this speed seems to drop sometimes to 100+Mbps; I was surprised by this because the TL-WPA8631P is rated at 300Mbps for the 2.4Ghz wifi. Otherwise horses for courses, 2.4GHz penetrates brick walls much better than the 5GHz and I switch off whichever wifi frequency works less well in the environment it is being used, typically using 5GHz only within a room and 2.4GHz between rooms through brick walls; it stops connected wireless devices sometimes choosing the less strong/fast signal; that’s a typical wifi issue not limited to these devices. The wifi TL-WPA8631P have excellent configuration options when using their web interfaces, including MAC white listing which I use extensively, and one can restrict a MAC (eg a child’s smartphone) so it can’t access WiFi at night. Being able to restrict MACs on a school night is essential, they learn soon enough not to use up their 4G phone data. I have not tried using OneMesh, my broadband router doesn’t support it and I don’t find the need for Mesh WiFi. Rather than have all network names (SSID) the same and experience the commonplace wifi issue of a computer hanging on too long to a weak signal from a distant access point and not knowing which access point you are connected to, all SSID names are different and we know where we are connected; that is fine for us. If you walk around your house while in a video conference your mileage might be different and need Mesh wifi.
Overall I have found these powerline devices amazing; for my purposes these devices beat dragging ethernet cables around the house. If you have Gigabit broadband and want to see it in distant parts of your property then wired ethernet might be the way to go (though I note powerline equipment with speeds faster than AV1300 are available which I have not tested) but for more modest speeds, like my 130Mbps broadband, and good house wiring, this might be all you need. I have not tried mixing different vendors, all our devices are tp-link. I’ve updated the firmware on both of the TL-WPA8631P, because it was there not because I needed to, I used the web interface but the downloaded tpPLC utility also has the facility to do this.
We needed one more when we had our broadband upgraded. This one had to go upstairs for the kids to do their homework as the wi-fi range was a little flaky.
I have a lot of TP-Link kit and they work very well with the router.
Literally, plug it in, press the pairing button, sit back, wait, job done.
Rock solid connection, can be configured for either streaming, gaming or general browsing.
It works with the other three to provide a full duplex network. Depending on the wiring of the house, anything up to about 750Mbps is possible. It provides and excellent wired and wireless connection.
In short, but these, they are simple to operate, the through plug is rated at 10A so perfect to run most applicances from.
An unforeseen side effect of installing roof insulation (with metallic layers!) was that this created a barrier to wifi reception in the garage and garden; the router is in the loft. So this extender kit was bought to install in the outside garage 15 metres away.
Initially I tested the extender using the Quick Installation which uses the default TP-Link SSIDs and password. This worked in the garage despite the transmission via the mains power passing through an RCD circuit-breaker. Having a different SSID (network) from the house is a bit of a pain so I then tried unifying the extender. This gave me a bit of trouble until I realised that the extender needs to be reset (under power) to the factory defaults first. I strongly recommend that the extender should be next to the router to unify using the Wi-Fi button. My problem was that the extender had not copied all the required data from the router when the router hit a time limit and its Connect/WPS light stopped flashing. The remedy was to just press the WPS button on the Fritz!Box router again and the extender then successfully completed its copying.
Performance seems as good as that in the house; but I do not stream data or game.
One issue was that my (new) iPad complained that the extender’s wi-fi (WPA/WPA2) was not secure. I downloaded the TP-Link Utility on my PC and upgraded it to WPA2/WPA3; this was remarkably easy.
We live in a 1950’s house with brick internal walls. A WiFi router is just enough to cover 2 rooms and a WiFi mesh system would not penetrate the walls. . With the AV1300 Powerline adapter connected to a Fritz!box router and 3x AC1200 WiFi extenders (1 in the middle and one at each end of the house), the whole house has a good signal and there are no dropouts. I’ve shared the Fritz!box WiFi log in details across all 3 extenders so now there is only 1 password for the whole system. This was achieved by pressing the WPS button the router and then the WiFi buttons on the extenders. The router is set as a mesh master and you can move around the whole house with your device and not notice any WiFi changeover or drop-outs. I’m also using the ports to connect to a smart tv, Apple TV and hue bridge. Very pleased with the whole set up. Would have preferred the ports on the extenders pointing towards the floor for neatness and to not obscure the on/off switch on the wall-socket, but the switch is rarely used. Also like the fact that there is still a socket available (pass through) on the front of the adapter and extenders. Highly recommended for older houses.
TL-WPA7517 KIT
I bought this Powerline Wi-Fi extender in order to get a better signal to the back of my house and back garden (where I have my outdoor Ring Floodlight Cam). My main router is in my front room and the signal was weak at the back of the house. This was so easy to set up, I plugged one end (the adapter) into the mains socket near my router and connected it via the supplied Ethernet cable. I then plugged in the other end (extender) into a mains socket at the far end of the of the room (40 ft long room). I followed the simple instructions and within minutes had a stronger signal at the back of the house even including upstairs. The Wi-Fi name was copied over so I don’t see a different network (unlike ordinary extenders) and my Floodlight Cam now gets a better signal.
This also works in conjunction with an existing Powerline I have (TL-PA4010P KIT).
My router is Virgin Hub 3
I am very pleased with this purchase and the seller.
We have a stone built building which does not transmit Wi-Fi signals very easily. It also has a complex mains distribution system. So I cautiously installed this device as a hopeful experiment. It has proved to be very effective. Can achieve useable Wi-Fi wherever we choose to plug a remote into the mains. It works with underground cables. We can get good Wi-Fi with it plugged into a garden building over 50 meters away! The application notes stress it should be on a single mains loop – you just need to check all the mains circuits come from a common supply service feed, the layout, complexity and number of branches seems irrelevant. Recommended for awkward reception sites.
Really good. I used them in my new home office to bust the signal. Works great for all my needs.
Has boosted my WiFi signal to my camera also allows children to watch tv in there room without me having to watch there rubbish later when they older will be useful when connecting a pc
I had a couple of issues with one adapter, but this was quickly remedied by tech support technician Jonaire with their online chat screen. I have used these adapters before a number of times, and can thoroughly recommend them.
This package came with RG45 sockets which was good for printer/scanner machines, the signal is very strong in any room (4 brick walls away from my router) – the advantage and convenience being it uses the AC supply as its signal connection.
We have been struggling to keep a good consistent signal with this product. Finally today we think we have the answer. The device ‘disappeared’ completely in our hub settings. Tried a few things before finally changing the Ethernet cable which came with the device and hey presto worked instantly. Disappointing and annoying that cable of such poor quality it failed within weeks. The rest of the equipment works well.
Needed a wifi connection in my workshop set at the end of the garden. Luckily I had a hard wired gigabit connection near the same house electric circuit to the workshop so the base unit could be plugged in and onto the main network relatively simply. (An absolute requirement for the system- it won’t work off two different electrical circuits).
Signals now run up the armoured cable out to the shed and to the wifi unit. It’s not the fastest of connections giving me adequate performance that end, but allows a wifi cctv camera to work well enough and serve the equipment in the workshop.
I bought this unit to extend my existing Powerline network and eliminates unsightly cabling that was causing some complaints from my partner. Installation was very simple, effectively plug and play, with the network being picked up immediately and allowing much shorter wired connections from the new unit to my home and work PCs.
The only issue I’ve had, and the reason for a 4 rather than 5 star review, is a (very!) occasional drop of the wired link and an auto-switch to wireless. However, resetting the network adaptor or just unplugging the unit for a few seconds has always reactivated the wired connection immediately.
I thought these modern links would be ‘easy’ to install….. however, they are fickle indeed! The box instructions – and indeed those included within – lead one to believe that it is childs play to get these links ready to use and operate. Not the case. I sent one set back after being told by a TP ‘chat’ assistant that there was a hardware problem…only to receive its replacement to find the same connection issue with the second extender. A use of the TP chat support system showed up the fact that – for the same issue – there were obviously many different approaches to ‘solve’ the same issue. In one case, I was asked to save the current settings and download new ‘firmware’ to enable the set to work! A tall order for a 68 year old retiree! Needless to say, I am still trying to get the second extender to show up on my system and mobile/laptop as a working part of the unit. That said, my first extender is working well and supports my TV well coupled with providing a strong wifi signal on my ground floor. I live ib hope that, one day, I will be able to get the second extender working!!
Decent increase in speed, the picture shows using a wired connection to my laptop. Wifi perfromance has also increased, although I dont have a Before picture for that. Previously I was using the TPLink AV600 which was fine, but I saw this item on a black Friday deal and so thought i’d upgrade. As with the AV600 I just couldnt get these to copy the wifi settings from my Virgin hub using the one-click WPS method. It thinks about it for a while and then fails. This is almost certainly a Virgin/Superhub fault not a fault with these. It’s easy enough to download the app from the play store and manually configure. I gave the Wifi the same SSID name as my main network and everything seems to work; my phone moves to the strongest signal. I mainly got this for the wired connection capability though and im really pleased at the speed increase. One thing to note is that the units are about 2 or 3 times the height of the dinky AV600, and the cable comes out the top not the bottom. I had to find another plug to use and run some ethernet cable because I didnt have sufficient clearance.
Erroneously gave 1 star review that wasn’t posted I believe as it didn’t appear just now. USER ERROR !
Swapped units around. Was about to send it back and thought let’s ring customer service. Not too long, polite, soon spotted my error. Works fine with broadband speed checker though readings of
utility room 45 ft from router lounge with router
ping 4ms 28 ms
throughput 13.98 Mb/s 57.71
linkspeed 27.00 Mb/s 192.00
Don’t look fantastic. Not technical so maybe another issue.
This is for a Hive external camera system which on current BT router has poor signal and so poor picture and lag on the other side of the house. Hive people returning so we will see if this is the solution. As a comparison signal in a bedroom on the other side of the house uses a Netgear wifi extender working without issue so far for simple computing and ethernet to tv for Netflix etc. as signal was so poor].
I bought this to boost the wifi signal to the upstairs of my new house, which was struggling from the router located downstairs. It works perfectly with much improved internet speeds in my upstairs home office (either by wifi or network cable), with no dropping out of Teams or Zoom calls as I was experiencing before. I was a bit worried that the upstairs and downstairs are on separate ring mains, but there is no problem with this – the powerline works fine passing through the consumer unit. Really useful to have multiple Ethernet ports as I can connect both my laptop and desktop computers at the same time. Only knocked off one star because my network’s SSID and password didn’t copy across automatically even when following the instructions, and I had to do this manually (not really difficult but it was a bit of a faff). Otherwise would highly recommend.
The TP-Link TL-WPA8631P(UK) AC1200 AV1300 power-line extender for Ethernet and wi-fi works a treat, exactly how we need it.
I paired it in just a few seconds with an existing TP-Link TL-PA4010 AC600 sender, and almost immediately the tlPLC Utility reported a stable link speed of 320Mb/s across 35 and 45 metres of ring main from the sender.
Security options are available for its wifi hub, via its wifi or wire linked from PC, when using a relevant Utility. They allow one to set robust admin name and password, as well as a strong wifi password. There are also options for timed access, parental controls, guest access, optimum mode of operation, wifi power level, everything one might need. I did not bother with OneMesh etc.
After reading the somewhat sketchy instructions with a generic EU picture for the different shape and inverted (but more ergonomic) UK device, initial setup and function test only took a couple of minutes. To do this I secured the admin name and password using the tlPLC Utility on the PC. Download of the latest version of the Utility from the manufacturer was quick, and detailed configuration for better security and usability took about ten minutes working through all the options. One useful option for intensive use is the ‘preferred usage mode’, but I’ve set it for internet as a TV only takes about 8Mb/s even on HD and our broadband is only 50Mb/s.
Wifi access to a crucial aspect of network security could be a bad thing or a good thing, so I’ve set a very strong admin password, just as I’ve done with the router. It may be more fiddly with a phone, but typing is easy on a PC, so no big deal.
One of my rooms is blocked from the wifi in the rest of the house by too much steel and masonry, but fortunately it is on the same ring main as my internet hub. This extender with the three ports and the remote wifi hub was ideal, and the TV and DVR are plugged into two of the ports while the wifi allows use of tablet, phone and laptop, all simultaneously while remote from the main hub.
I set a different wifi password and hub name from the main hub simply for convenience of setup and better security although they could have shared them, and because previously one phone had difficulty in deciding which hub to use when the password was the same. Two different passwords and the phones, tablets and laptops change hub seamlessly as we walk around the house.
It replaced an increasingly unreliable old TL-WPA4220 AV600 . The louder the whistle from its power supply, the less effective that old one became. It died just a month out of warranty, but I could not be bothered with the hassle of arguing about something so cheap.
Ok so first things first. Can confirm it works MUCH better than the old version I tested it against (AV500). Before I get into the speed test I’ve done, just note the following test assumptions: the house I tested it in has a 1Gb fiber optic internet connection, laptop used has the latest 10Gb LAN port and 1Gb wireless card and also tested everything with latest Cat6A cables. The house where I installed this is c. 2,700 sqf, it’s a traditional Victorian terraced house with ground floor, first floor, 2nd floor and attic. I plugged the unit in the sitting room on the ground floor. A Cat6A cable was used from the router into the TP unit. The broad overall download speeds I managed to get are: 110-266 Mbps using the LAN port of the wireless extender, 55-100 Mbps on the 2.4Ghz Wifi connection and 111-280 Mbps on the 5Ghz Wifi connection. Both the laptop wifi card AND latest iPhone produced similar wifi results. The range in the Download speeds mainly due to distance between wireless extender and main TP unit. Room by room tests below (remember the main TP unit and router were located in the ground floor sitting room).
Ground Floor / Sitting room. So I plugged in the wifi extender in another socket in the same room with the main unit. I got 266 Mbps on LAN, 95 on 2.4 GHz and 280 on 5Ghz. I was a bit surprised by this result. I would have expected MUCH higher speeds on both the LAN and Wifi given the wifi extender and main unit were placed in the SAME room, just different plug sockets! By way of comparison when I was connecting the laptop directly to the router I was getting 950 Mbps on LAN and 625 Mbps on 5Ghz wifi.
1st floor / room above sitting room. 156Mbps on LAN, 53 on 2.4 GHz and 173 on 5Ghz
2nd floor. 151 on LAN, 72 on 2.4Ghz and 155 on 5Ghz
Attic. 124 on LAN, 80 on 2.4Ggz and 132 on 5 GHz
Easy to setup… even though it’s not too obvious where the potential fault is should it fail in ethernet connection. I first bought this at the beginning of Oct and setup the extender for ethernet use. The gigabit speed and 3 ethernet was a big selling point. I am using a laptop and VOIP phone for work. So my connections need to remain stable. After just a few days use the extender started to drop connection requiring several resets finally the extender failed completely. Disappointed I was ready to giveup but on the Amazon return screen I had the option “how can we make it better” and chose to replace it with another one. Much to my surprise it turned up a day later and worked straight out if the box. It dropped connection once since that time and I only cycled the port on and off to get it going again. No fiddling with settings or WiFi required. To avoid complications I was willing to use the default names for the connections but it actually cloned the WiFi ethernet names without blinking. I only used two of the three ethernet connections available so I’m more than happy that I have one spare. It is expensive compared to other makes I’ve seen but it’s worth it when It all works the way you want.
I bought this to add the capability of a wired network connection in my wife’s outside office (using the power sockets that are spurred off the main house) and to also extend the WiFi into my daughter’s bedroom, which is in the opposite corner to the current TP-Link Wifi Router as the current signal is weak.
To set up, took around 30-45 minutes all in. The single sheet guide in the box is all you need.
It does recommend downloading their app to install – which I did. Once installed, the app has basically served its purpose as all the data on it is available through the web interface of the extenders (192.168.0.XXX).
The hardwired CAT-5 link works flawlessly in my wife’s office. A speed test gives around very similar speeds to being directly connected to the main house router.
The Wifi extension upstairs also has a CAT-5 output, which I’ve tested successfully. But I use for the Wi-Fi only at present. It is okay and gives a strong signal out – enough for my daughter. I’ve “cloned” the main WiFi SSID (details on how to do this are in the box) which gives a basic mesh network in the house. However, I’m sure there is a clash with the main wifi, as some points in the house now give a lower signal. A simple switch on and off on my phone/tablet/laptop usually gets it to pick up the stronger of the signals – buts it’s not seemless.
There IS an update coming to this set (AV600) that will give native mesh networking when used with a TP-Link router – but this hasn’t been rolled out yet (July 2020).
Overall, I’m impressed. It’s served it dual purpose brilliantly – and not bad for 65 at time of purchase
I’ve been using TP-Link Powerline’s for many many years to bring internet through mains-power sockets to devices such as smart TVs for catchup (where WiFi was too unreliable).
Thought I’d give this set a try to also bring WiFi into rooms that had zero or a patchy signal from our far away router.
It works, fantastic!
I did the trick (detailed in the instruction sheet) to copy the same ID and password from my router – so I didn’t need to log-on to a new ID/password with my devices, everything is seamless. My router transmits two WiFi signals, 5GHz and 2.4GHz, the TP-Link transmitters picked up the 2.4GHz ID & password (and I assume they also transmit at 2.4GHz as the max speed is 300 Mbps – which is way faster than our BT ‘superfast’ here, 30 Mbps).
Getting the end units paired with the source unit, as I know from experience doesn’t always work first time. Actually I’ve found it best to physically link the end unit to a computer with an ethernet cable (and turn it WiFi off on the computer!), just so the end unit is actively wanting to supply internet to a computer. Then do the pairing procedure, press the source unit then the end unit. Then you can unplug the end units and put them where you want. The WiFi units strength covers a couple of medium-large rooms each, it’s not a super-strong whole-house signal, but for it’s purpose works 100% within the room of each transmitter, and also 100% through the wall of the socket the transmitter is plugged into, to the adjoining room.
I also downloaded the iPhone app, to turn the LEDs off, works, great; but the app isn’t essential, you don’t need it. The ap also allows you to control off times for the WiFi of each transmitter, if that may be of interest.
Also older TP-link Powerlines (which I have a few of!) also work fine with the new system (and the app).
Note : this is both a Powerline system and a WiFi extender. Some models are *only* WiFi extenders – which require a good WiFi signal to bounce that signal on further like a relay race. As this is using Powerline, the internet goes through your main’s wiring near your router, then the end unit which can be far beyond any existing WiFi signal, picks up the internet through another mains socket, then transmits a fresh WiFi signal from that location. Great!!
