Edimax EW-7822UAC linux driver

창고에 던져놓고 무선으로 연결하여 사용할 offsite 백업 서버를 위해 아마존에서 구입한 USB AC1200 Adapter. 페도라 23에 드라이버가 없다. 다음과 같이 설치.

$ git clone https://github.com/abperiasamy/rtl8812AU_8821AU_linux.git
$ cd rtl8812AU_8821AU_linux/
$ make
$ sudo make install
$ sudo modprobe 8812au

동일 로컬 네트웍에 기가빗 유선으로 붙어있는 다른 리눅스 서버와 속도 테스트. WPA2-PSK (AES) 사용하고 신호에 따라 200~270Mbits/sec 정도 나옴. 그럭 저럭 쓸만.
