TP-Link Wired Passthrough Powerline Adapter Starter Kit, Advanced Protocol G.hn MIMO, Extra Power Socket, 2+2 Gigabit Ethernet Ports, No Configuration Required, Plug and Play, Pack of 2 (PG2400P KIT)

Does not work as

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.

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.

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.
