The installation was very easy. Since I have no CD drive, I downloaded the latest driver from the TP-Link page. But this is still 2013. The driver installed but directly with me and the key has been detected. The installation had to be done via the device manager. There is no .EXE file it.
After the 5th Speedtest the stick has apparently suspended. There was no Internet, although in Windows the bars were displayed at the bottom right. I could also switch between the 2.4 GHz and 5 GHz band. The Internet still did not go. Even local access to the router no longer walked.
After I had the stick then staked out and left for 3 seconds off it worked again.
Due to this misfire, which has also been frequently mentioned in the comments, I give 4 out of 5 stars.
Perhaps this is also the inventor had come in the day drivers ...

Time and again these hangers. Especially when a lot of data on the drive to the NAS, or even over the Internet are transferred.
Feels like every 1-2 days 1 times. It's frustrating. I have now tried also the newer driver from Realtek. Thus, it is not much better.
If the hanger occur the reception bar under Windows are still present, only the speed collapses completely. Then either nothing is possible or felt more than 5kb / s, which is ridiculous.
I have the stick today sent back and ordered a new one. But there's a star so deliver 3 out of 5.
If the new drive is better, I'll note that in accordance with this and adjust the rating.
