Review on High Performance AC1300 USB WiFi Adapter for Extended Range, Dual Band 2.4GHz/5GHz Wireless 📶 USB 3.0 Network Card for Laptop Desktop PC, Compatible with Windows 7/8.1/10/XP/Vista, Mac OS X10.6-10.15 by Brandon Teitel

Installed for Linux Debian without a network connection. First off, the drivers on the CD and on the Wise Tiger website are for the 8821au chipset, which is inconvenient since it's an 8812au chipset. Your install.sh driver ran and installed the 21au module just fine, but my system refused to recognize/use it because lsusb saw the adapter as 12au and apparently can't use the 21au chipset module. Found the 8812au driver module from the web (the guy on github had a nice site working on some of the stability issues other people mentioned) using a different search/download system. After running the install for 12au and activating the module, my Lite adapter worked right away. The connection to the legacy USB2 port is slower than the USB3 port, but it's still decent, and this adapter has been pretty reliable so far (used about 4-6 hours a day per week).
