The speed on the WiFi drops from 300mbps to below 40 even when connected to the same line. It disconnects at regular intervals, whether the connection is WiFi or wired

The best thing I have bought in an online product. For less than 100 euros, you have fast internet in 2 rooms through the power network.

We solved once and for all the problem with the internet on the third floor! Many people simply don't know that in order to do their work to the maximum potential without any losses, they should ideally connect to the same power lines as the router, preferably on a different floor. Calculate which socket on another floor is in line with the router. Also, don't plug too many devices into a power strip, as there will be losses. Either plug it into a socket on its own or use a T-shaped socket. It's very convenient if you have a large surface area and if you need to move it to another room, you can simply unplug it from one socket and plug it into another.

It was set up very quickly and the application was easy, it found them immediately from the network.
No loss in wireless speed. Very good

The big problem is that it doesn't have an outlet, and (it says) it shouldn't be plugged into a power strip. So, what? In order to use the computer and power it up, do I need two outlets side by side? Does that make sense? Anyway, it works

February 3, 2021: First day of operation and all three devices connected immediately. Each device on a different floor (3 floors with different panels). I will update for any developments.

Very good especially for home use, the only downside is the connection to the network, definitely not plug and play, it took me an hour to connect them, if you overlook that, everything else works perfectly. I use it in a maisonette and all floors have the same speed without disconnections

Attention, do not place it in a socket... It will not perform well. Follow the instructions and the losses will be minimal in mbps. Be careful to write down the passwords somewhere for WiFi access. I highly recommend it for home users who want to extend their coverage within their house. Oh, and it only works in sockets of the same power supply... It will not work in another house even if it is next door and has a different power supply.

From the second floor (router), I moved to the first floor where I could only catch wifi signal at one point, and I also moved to the ground floor where I couldn't catch anything... well, now I get signal everywhere... easy installation... I solved my problem...
Update... Unfortunately, after three months, I can say that almost every day you have to unplug and plug it back in to make it work again... It freezes and it's annoying... but okay, I got used to it now...

It does not have disconnections, it is convenient because it has more extensions but it has a greater loss than the previous model of TP Link that I was using. Overall, I would recommend it as a product, as it is stable and does not heat up too much.

Plug n Play is not what you would call it... I was trying for 3 hours following the instructions to set the same SSID and Password as the cosmote router. The automatic process with the router's WPS doesn't work... The Android app doesn't even have this setting. Eventually, with TP-Link's online tool, they can be changed manually but... they don't have internet after the change. Only with the default SSID and password they can connect. 3 stars.

He played on a three-phase, three-story below! Simple synchronization process! On a 50-line cable, it reaches 49 and with wifi 30+! Just got it, I don't have an opinion yet on disconnections!

Very good, it solved the issue I had with weak wifi signal in a three-bedroom house. Good Ethernet distribution, with sufficient speed both wired and wireless, while in a neighboring house I used one adapter as a wifi signal provider for further signal extension with a tenda extension, which connected directly without any issues.
As for the user instructions, they are very simple and if followed correctly, the whole kit connects seamlessly.

Another TP-LINK product that has left me fully satisfied. Just like the Powerline kits and singles, this three-piece (2+1) kit works very well without any disconnections, even when used in a power strip.

No disconnection during one month of use.
Use in a three-story house. Transfers the speed to the integer.
Worth it.
Negative, it heats up quite a bit.
