Review on High Gain Wireless Network Adapter - TP-Link Nano USB Wifi Dongle with 150Mbps Speed for PC Desktops and Laptops. Compatible with Win10/8.1/8/7/XP Linux 2.6.18-4.4.3, Mac OS 10.9-10.15 (TL-WN722N) by Darius Glatzel

Advantages: It gives you WIFI. Here's the rest.1. If you want to use it, please install the drivers. I got 40% speed while doing this.2. The adapter was easy to install, but due to the fact that there is only one antenna connector, you may have trouble aligning the antenna properly with your wireless router. We finally bought it in January, but now it's dead in April. The room it was used in didn't have excessive humidity, the PSU wasn't subjected to physical shock, and the ambient temperature it was used in , never exceeded 68 degrees Fahrenheit. It has also been plugged in and unplugged less than 10 times. This leads me to believe that the problem is with the board, with the soldering quality control, or with the chip not having enough passive heat dissipation. I tested it on several other devices and it doesn't turn on.
