Well. After a considerable amount of time using it, I have to say that it is NOT the most sensitive antenna on the market.
If you are interested in low ping for online gaming, let's say. It's good for the wifi to be less than 3 meters away. I don't know if this improves with another antenna that can be adapted to it. But I'm talking about the user experience with everything included in the package as you buy it.
Apart from that, it is a decent plug and play without needing to do anything. What you plug into the PC, it recognizes it. That's it.
It never had the slightest hardware disconnection.

For now, after 1 month of use, everything seems good... the future will show!
It was immediately recognized in win10.

For its price, it is a good choice. It receives signal to a satisfactory extent, the main issue is that it frequently disconnects. I would not recommend it for those who work remotely. It is good for browsing and watching videos, but only up to that point.

Very good for its price. Quite good signal despite the two walls that are between the router.

With 2 extension cables at 3 meters (+5€ from abroad), you get a perfect 5 out of 5. Without the extra cables, I had some issues. For those who don't want or can't have holes in walls, channels, etc. to have Ethernet, it is highly recommended 100%

I have had it for 1.5 years. On a PC on the first floor, it initially worked decently, not good speeds and quite unstable. After a few months, problems started with the IP, which it constantly loses and requires reinstallation. Bad choice. I would not buy it again

Immediate installation on Windows 10 desktop. I got it as a replacement when the onboard chip of my motherboard burned out along with the TP-LINK TG-3468 v3 ethernet.

A great card, with a relatively stable connection and at a reasonable price, perfect for covering unused PCI-x1 ports on your motherboard and accessing wireless network without cables. I was able to achieve speeds of 43+ Mbps on a 50 VDSL connection, at a distance of 5-10 meters, so you only have limitations from any physical obstacles that may exist in between!

I bought 2 for 2 desktop computers that I have at home. No issues with their performance, but they had a limited lifespan, both of them.

In a 50 Mbps VDSL connection, the download is fine at 46 Mbps with WiFi, but the upload is only 0.2 Mbps! It's not the router's fault because no other wireless device has low upload speed. I suspect there is an issue with the transmission power.

Update: I tried a different network card and had the same issue, so the problem is with this specific card

I have 2, one on my own PC occasionally increases the ping but overall it's fine. The other one on my parent's PC has no issues with disconnections or ping. Highly recommended.

The aforementioned card is an economical and good solution for simple use, I would say. Its installation is very easy and the package also includes a small bracket, which can be easily changed. The two antennas even provide better range.

On the other hand, the card sometimes experiences significant fluctuations, resulting in difficulties with upload. Generally, reliability from a trustworthy company like TP-LINK exists, but perhaps for a perfect result, you should choose a slightly more expensive option with three antennas.

Very long range, I reached 40mbps on a 100mbps connection, but if I had a better router, I would definitely reach much higher speeds. The installation program is easily found on the website. The best value for money!

Very easy connection and installation.

Compared to the Chinese antenna for 1.5 euros, the signal did not increase at all, maybe even dropped a line.

However, in terms of speed and stability, I noticed some differences. Not a single disconnection in the past 2 weeks, latency (website) dropped from 51ms to 32ms, and download speed increased by 1.1 Mbps from 5.1 to 6.2. And all this without having a router with 2 antennas to fully benefit from beaming.

I will try as soon as possible a direct connection with a cable to the router for comparison.

A good and reliable purchase with the option to buy larger antennas if needed.

It was easily installed, immediately recognized by Windows 10 - so the installation CD was not needed. However, the two antennas were not sufficient. I needed an extendable antenna (an old Asus one) in my case. It was placed next to one of the two antennas that the tp-link comes with. Anyway, compared to the previous network card that used exactly the same antenna - with the tp-link, the signal is 3-4 times stronger, much better.
