WiFi for my garden room
This product is a life saver for us, we use it for a garden room that has a power supply from the house, and it’s spot on. Very easy to set up and I can now use multiple connected devices and there is no drop in performance. I am really impressed with this device

Solved Lag Spikes On PS5 - Exceptional
I was skeptical at first if this powerline adaptor would actually work with mixed opinions online. But it is doing an exceptional job and was easy to set up. My PS5 was suffering lag spikes repeatedly making Cod Bo6 and Fifa difficult to play. My router is on the other side and lower floor of my house meaning weaker wifi signal and interference. I have now had this powerline connected to my PS5 with ethernet for some weeks and i am no longer lagging with steady ping and no packet loss. The download speed is near enough close to full mbps my isp provides and is steady. I even have my BO6 texture streaming on full and there is still no lag with this amazing item. In regards to the wifi extender part of this product, it is decent but does not perform as well as the powerline ethernet connection and download speeds are smaller in comparison. So if you are looking for an adaptor that will solve lag on devices that can be connected with ethernet, it is perfect but not the best option if you want to extend your wifi signal itself to phones and such. It will also depend on your houses electrical wiring and is recommended to be on the same circuit. I didn’t check my circuits or wiring and tested my luck. This product is working perfectly for me and solved my issues hence i give 5 stars!! It is worth trying and if it doesnt work well in your case, it can be returned within the time window.

Solid Performance, Great Value – TP-Link WiFi Extender is a Reliable Solution
I’ve been using the TP-Link WiFi Extender for a few months now, and it has significantly improved my home network’s coverage. Setting it up was a breeze, thanks to the easy-to-follow instructions and the Tether app, which made the whole process super straightforward. The device quickly found my network and boosted the signal in areas that were previously a dead zone. The performance is great for everyday use—streaming, gaming, and browsing are all much smoother with fewer interruptions. The range is solid, and I’ve noticed fewer dropped connections throughout my home. It’s also relatively compact and doesn’t take up much space, which is a nice touch. However, there are a couple of reasons I’m not giving this 5 stars. While the extender works well in general, there’s a slight dip in speeds when compared to being directly connected to the router, especially in areas farther away from the device. Additionally, the design could be a bit more streamlined—while it’s not bulky, the positioning of the antennas could be more adjustable. Overall, the TP-Link WiFi Extender is a fantastic product for the price. It does exactly what it promises and provides a noticeable improvement in Wi-Fi coverage without breaking the bank. Highly recommended for anyone looking to boost their signal and eliminate those annoying dead zones!

Great product
Works really well, easy to set up, once you know how 😉 Boosted the signal to a room at the back of the house that was a "dead" zone. Definitely recommend 👌

Perfect for getting Ethernet upstairs
Bought this mainly to get a wired Ethernet connection to my upstairs PC and it’s been spot on. Setup was simple, plug one adapter into the router and the other upstairs, pair them and you’re good to go. My PC now sees it as a normal Ethernet connection. Much more stable than WiFi for gaming and downloads, with consistent speeds and no random drops. Ideal if you can’t run long Ethernet cables through the house. Works exactly as advertised and does the job well.

Frustrating and didn’t work at first
Had an earlier TP link connector that worked great but wanted a dual Ethernet version so upgraded to a newer version. Wish I hadn’t bothered. The new one arrived and following all instructions and with all lights illuminated as they should be I connected my devices to discover that nothing could connect. Tried troubleshooting but all to no avail. In the end gave up and went back to the old system. Update. Went back a few days later and tried to set up again. Again nothing at first but finally got it working by power cycling all my equipment including router whilst keeping the tp link powered. Since then it appears to be working without fault. I’m keeping the review score at 3 stars as this is supposed to be plug and play not plug and power cycle everything else.

Great for dead spots.
This was great for a dead spot in my house. For me it tended to max out around 80mbps but that might be down to old wiring in the house.

Great product but pricey!
My initial review, received this product on time, thanks to Amazon delivery! Installed the power line wifi extender to support main internet line in my garage cum office. I did not have bandwidth to put cabling as the structure from my wifi cupboard and the garage is little odd. The product looks good. Simple plug and play. Worked straightforward. Will check its durability in terms of connection drop and any other issues and update the comments here. One thing I want to highlight here is that it is pricey.

Easy to set up as long as you read the full instructions. They act as WiFi extenders. A little slow to contact your WiFi but much cheaper option to a mesh setup.

It has made the WiFi slower all over my house, even downstairs close to the router, I get 350mbs with it off and less then 200 mbs when it’s on. I will be returning.
