I have the TP-Link TL-WN8200ND 300Mbit / s High Power WLAN USB adapter for several months now in use and am of the performance of the device very enthusiastic, the reception is excellent despite very thick walls and through the cable, it is very easy bring in a good position.
It is disappointing, however, that the device frequently crashes, the device is no longer recognized by the PC. By switching off and plugging in the USB cable, it can, however, turn quickly. Still, it's not very comfortable, and often leads to frustration.
