RTL8812AU/21AU and RTL8814AU linux driver with monitor mode and frame injection

Credit to astsam and ulli-kroll and the kali linux folks for porting this driver, the guide will help you make the AWUS 1900 Work in Fedora, it might work else where, but i can't garantee it.

The drivers work and can capture WPA handshakes, which the previous one didn't work on my setup, i hope this helps others.

The chipset driver is RTL8814AU

for Fedora26

• sudo dnf install elfutils-libelf-devel
• git clone https://github.com/madmantm/rtl8814au
• make RTL8814=1
• sudo make RTL8814=1 install
• sudo modprobe 8814au

plug your adapter and everything should work.

for Kali Linux

apt install realtek-rtl88xxau-dkms.

configure monitormode

Note : airmon-ng doesn't work to make the card go in monitor mode you have to do it manually.

• sudo airmon-ng check kill
• sudo ifconfig wlan0 down
• sudo iwconfig wlan0 mode monitor
• sudo ifconfig wlan0 up

to make aircrack-ng use the 5ghz bands

sudo airodump-ng -c 149 wlan0 -w psk --band a

Note : i do not own these drivers, not looking for credit, only a method to make these work with my setup.
