TP-Link TL-WPA4220 KIT AV600 Powerline Adapter WiFi Extender Kit, Wi-Fi Booster/Hotspot, Speed up to 300Mbps, 2+1 Ethernet Ports, Powerline WiFi Extender, Wi-Fi Auto-Sync, UK Plug, Plug & Play

Set up was straightforward and quick. Although the two units are on separate distribution boards, the ethernet traffic seems unphased by this and the link works fine. I'm only using this to connect a heating controller to web, so I can't comment on ultimate speeds or latency, but it is reliable and good value.

I purchased both a TL-WPA4220KIT and TL-PA4010KIT as part of the same home WiFi solution. As such, I have given the same review for both purchases. We have a long thin Victorian house with a BT HomeHub-5 in the front lounge. We have a ‘copper’ connection to the BT exchange as fibre is not available in our area of London yet. That said, we usually get a reasonable 9-10Mbps connection. Our problem is that we cannot get usable WiFi coverage in the kitchen at the rear of the house. We initially tried to use WiFi signal extenders but these proved slow and unreliable. So, about 3 years ago I purchased an AV500 PowerLine solution from SAGEMCOM. This included a Powerline WiFi extender in the kitchen. This proved to be adequate though we did need to reset all of the adapters about once a month when things ‘locked up’. Then, a month ago, the WiFi adapter in the kitchen handed in its cards and died. Thinking I would try for a higher-tech solution I purchased a WiFi Mesh solution on Amazon. However, this proved to be a complete disaster being slow and totally unreliable. I suspect this was due to the requirement for overlapping WiFi signals between the nodes. Also, as we live very close to the Crystal Palace TV transmitter, we are susceptible to RF interference. So, it was back to the drawing board and I returned to the tried and tested PowerLine solution. I chose these AV600 kits as I have always liked TP-Link products and found them dependable and reliable. As such, in total, we have 3 x TL-PA4010 mini PowerLine adapters and a TL-WPA4220 WiFi extender (in the kitchen). One of the mini adapters in located in the lounge and is connected with a LAN cable to the BT router. The other 2 adapters are in the bedroom. One is connected to a BT YouView box and the other to a Roberts Internet Radio (neither of which support WiFi). A secure network was made by connecting all 4 units in turn by use of the ‘pair’ buttons. All then burst into life and worked fine. The WiFi extender was using its factory SSID and password. I successfully trialed changing this by logging onto its admin screens using a browser (you will need to know its IP address to do this – I picked it up from the BT Hub setup menus). But then, I used the ‘WPS’ method to clone the BT Hub SSID and password instead by, temporarily, moving the extender to the lounge and following the easy ‘quick setup’ guide. This worked a treat and everything has now worked without hiccup for over a month. I have had previous issues with cloned SSID’s - with mobile devices getting confused when connecting. However, thus far, we have not had any problems and devices switch between the BT router and TP-Link extender (as we move around the house) without issues. That was a pleasant surprise! I did get the tpPLC android app for my mobile and its quite informative. It has a poor rating in the Google Play Store but this is IMHO, unjustified. It has no whistles and bells or astounding graphics but it does a job simply and well. I can see the status of all adapters and the speed of communication between each one. I seem to be getting a respectable 380-450 Mbps between each device except when they are idling and the communication rate drops to, I presume, a default 11 Mbps. The app also allows you to rename the devices (which may be useful for any future trouble shooting) and it can used (apparently) for firmware upgrades. Alas, it cannot be used to restart devices (it only allows a factory reset). Nor, can it be used for changing the settings (SSID ID etc) on the extender – this can only be achieved by ‘browser’ access. So, we are pleased. This solution is (thus far) reliable and is reasonably priced. It is also easy to set up (though my prior experience in this area helped) and it’s a step up from our old SAGEMCOM PowerLine solution. Had BT supplied us with a higher speed ‘fibre’ internet connection, I would have gone for say, an AV1200 setup with dual band WiFi. As it is, this meets our needs. Also, if you have a shortage of mains outlets in your house, you may want to opt for more expensive ‘mains pass-through’ adapters. NOTE. I see there are a number of debates on Amazon regarding the reliability of PowerLine solutions. ie. Some people are extremely happy while others have persistent problems. This is not peculiar to TP-Link products. Based on my experience, I would suspect that performance is directly related to the state of the house mains wiring. Our house has recently been rewired which not only improves (and reduces the number of) connections, but potentially shortens cable runs too. As such, unfortunately, a PowerLine solution may not be ideal for everyone - particularly in some older houses with extensions and complications added over the years. You may need to 'suck it and see' to decide if it works for you.

I've been using this power line adapter for almost a month now and it has worked perfectly most of the time. It has eliminated lag from playing online games and my ping is greatly reduced. They were easy to set up just plugged then in and they synced up right away. If you're more technical you can also access the devices seperate control pages using their IP and configure them more if you want to change any settings. But the default should be perfect for most people. The only issue I had, which only ever occured once was the connection stopped work and a red light was flashing on the devices. However unplugging and replugging them in fixed this issue and it has not happened again since. Overall a very good product would highly recommend to anyone looking to get a more stable internet connection if they're far from their router.

I had already installed a Velop mesh WIFI system in our new house and that works really well. It does rely on you being able to hop from one base station to the next and provided they are in range all is well. Not cheap by any definition but does provide a single cohesive network for the whole house. We recently renovated some outbuildings into workshops and garages and while this was wired from the main house the WIFI strength made the mesh extension option a bit risky as the signal that would need to be boosted was very weak. I came across this product while researching alternatives and was pleased with the excellent reviews on Amazon and decided to give it a go as the cost was not prohibitive in any way. Set-up was very easy and despite the instruction that you connect the base as close as possible to the router I found that the length of power circuitry was a more important factor. I tried "the close to router" approach but the WIFI station failed to pair. I had installed a Cat 7 ethernet system in the house when it was being built and had a number of ethernet ports in various locations to choose from. When the base station was relocated on a shorter spur to the main fuse board it paired successfully and provided a solid WIFi signal in the workshops. The main connection into the house is 300 MBs and even though the signal delivered in the workshops is a fraction of that at about 12 to 20 MBs it is perfectly adequate for what we need. The workshops are connected to the main house by a buried steel wire armoured cable and they have their own distribution board. I was pleased that the devices worked over this configuration and have no doubt that extending within a house on the same circuit would deliver considerably higher speeds. Take it from someone who spent in excess of £600 for WIFI mesh systems that this much cheaper option, with the WPS integration, would provide an equally good solution. Highly recommended and excellent value for money.

Great speed boost. I got this to replace an old 120Mbps Tplink and it has been a great choice. The through flow of data has been boosted to match my fibre speeds. set up was easy enough but the two minute window to pair the devices could have been a bit longer to allow getting access to the units. All in all I highly recommend the Tplink passthrough system as a very reliable kit that really gives the speed that it offers.

For backstory I've recently upgraded my broadband to gibabit, and before had a maximum speed of around 70 Mbps. Using my old TP-Link powerline adaptors I was able to get up to the 70 Mbps without issues - although the reliability of the broadband itself was another matter with speeds averaging between 40 and 60 Mbps. I'd put my second adaptor into an extension upstairs - no change to performance. I decided to try these new pass-through TP-Link adaptors. They feature a pass-through socket and are pretty huge compared to my old ones. Due to where the new hub was located both powerline adaptors were now going to have to be on an extension (not ideal) without me having to start moving stuff about. The speed was coming through suspiciously as with the old adaptors, steady around 70 Mbps. I downloaded firmware updates and started using the TP-Link software. No change, so I then put the second adaptor which is upstairs and links to the PC directly into the wall and tried again. The TP-Link software showed my powerline rate averaging at above 300 Mbps. Now this is the theoretical maximum rate. Real world speeds should be much less. My speed tests were now coming in at over 100 Mbps - peaking around 130 Mbps, with upload steady at around 85 mbps. This is great as a starting point. I've potentially doubled my download speed. I then went to put things as they had been originally, so now both powerline adaptors were plugged directly into the wall. My powerline rate was now showing as over 800 Mbps with a consistent download speed test of 130 Mbps, peaking at 150 Mbps but with upload speeds now averaging around 40 Mbps – a 50% drop. I'm guessing that because the adaptor was going into a double socket that it just can't cope with the busy electric traffic nearby. I then tried a £15 wireless USB-3 dual-band adaptor and plugged this into the PC. Using this cheap adaptor over wireless I am able to consistently get over 200 Mbps download and over 100 Mbps upload. Ping times were very similar between using these adaptors and the Wi-Fi adaptor, however using the TP-Link powerline adaptors download latency was noticeably higher. Everyone’s experience with these will be different – it will depend on your own electrical wiring setup at your property, your broadband provider’s hub/router and more. I ended up with a new hub from my new broadband provider that gives me pretty decent Wi-Fi coverage. If you are able to get a decent Wi-Fi signal in your room of choice – test it on your phone for example, then a cheap Wi-Fi adapter or even going down the Wi-Fi mesh route will probably be a better option. If Wi-Fi is an issue, which is why you’ve probably considered powerline adaptors, and you don’t want to get too complicated with a Wi-Fi mesh system or start drilling cables through your walls then yes, Powerline adaptors remain an option. Just don’t expect them to get close to the advertised speeds under most real-world scenarios.

Very easy to use, plugged it in and that was it, worked perfectly

I would give 0 stars if possible. Unlike Ronseal this does not do what it says on the tin... no where near. After first plugging in the devices they link up as expected and give network connection over the power lines. For context my house is brand new, built in September 2025 and is compliant with the latest electrical standards. We also have full fibre up to 900mbps. I noticed after some initial speed tests the devices are only giving up to 200mbps when across the house from each other. I updated the firmware and also put them both in the same socket gang to see if the speeds would improve... the did not. TP-Link please dont advertise what you cannot promise. They may link in your software at 1100mbps but real world speeds fall far from your expectations.
