RTL8812AU/21AU and RTL8814AU drivers
Only for use with Linux & Android
Important!
* Use "ip" and "iw" instead of "ifconfig" and "iwconfig"
It's described further down, READ THE README!
* v5.3.4 is the stable branch, not this, but this does have
better range then branches below + more fixes from Realtek

DKMS
This driver can be installed using [DKMS]. This is a system which will automatically recompile and install a kernel module when a new kernel gets installed or updated. To make use of DKMS, install the dkms package, which on Debian (based) systems is done like this:
$ sudo apt-get install dkms
Installation of Driver
In order to install the driver open a terminal in the directory with the source code and execute the following command:
$ sudo ./dkms-install.sh
Removal of Driver
In order to remove the driver from your system open a terminal in the directory with the source code and execute the following command:
$ sudo ./dkms-remove.sh
Make
For building & installing the driver with 'make' use
$ make && make install
Notes
Download
$ git clone -b v5.6.4.2 https://github.com/aircrack-ng/rtl8812au.git
cd rtl*
Package / Build dependencies (Kali)
$ sudo apt-get update
$ sudo apt-get install build-essential bc libelf-dev linux-headers-`uname -r`
For Raspberry (RPI)
$ sudo apt-get install bc raspberrypi-kernel-headers
Then run this step to change platform in Makefile, For RPI 1/2/3/ & 0/Zero:
$ sed -i 's/CONFIG_PLATFORM_I386_PC = y/CONFIG_PLATFORM_I386_PC = n/g' Makefile
$ sed -i 's/CONFIG_PLATFORM_ARM_RPI = n/CONFIG_PLATFORM_ARM_RPI = y/g' Makefile
But for RPI 3B+ & 4B you will need to run those below which builds the ARM64 arch driver:
$ sed -i 's/CONFIG_PLATFORM_I386_PC = y/CONFIG_PLATFORM_I386_PC = n/g' Makefile
$ sed -i 's/CONFIG_PLATFORM_ARM64_RPI = n/CONFIG_PLATFORM_ARM64_RPI = y/g' Makefile
In addition, if you receive an error message about unrecognized command line option ‘-mgeneral-regs-only’ (i.e., Raspbian Buster), you will need to run the following commands:
$ sed -i 's/^dkms build/ARCH=arm dkms build/' dkms-install.sh
$ sed -i 's/^MAKE="/MAKE="ARCH=arm\ /' dkms.conf
For setting monitor mode
- Fix problematic interference in monitor mode.
$ airmon-ng check kill
You may also uncheck the box "Automatically connect to this network when it is avaiable" in nm-connection-editor. This only works if you have a saved wifi connection.
- Set interface down
$ sudo ip link set wlan0 down
- Set monitor mode
$ sudo iw dev wlan0 set type monitor
- Set interface up
$ sudo ip link set wlan0 up
For setting TX power
$ sudo iw wlan0 set txpower fixed 3000
LED control
statically by module parameter in /etc/modprobe.d/8812au.conf or wherever, for example:
options 88XXau rtw_led_ctrl=0
value can be 0 or 1
or dynamically by writing to /proc/net/rtl8812au/$(your interface name)/led_ctrl, for example:
$ echo "0" > /proc/net/rtl8812au/$(your interface name)/led_ctrl
value can be 0 or 1
check current value:
$ cat /proc/net/rtl8812au/$(your interface name)/led_ctrl
USB Mode Switch
0: doesn't switch, 1: switch from usb2.0 to usb 3.0 2: switch from usb3.0 to usb 2.0
$ rmmod 88XXau
$ modprobe 88XXau rtw_switch_usb_mode:int (0: no switch 1: switch from usb2 to usb3 2: switch from usb3 to usb2)
NetworkManager
Newer versions of NetworkManager switches to random MAC address. Some users would prefer to use a fixed address.
Simply add these lines below
[device]
wifi.scan-rand-mac-address=no
at the end of file /etc/NetworkManager/NetworkManager.conf and restart NetworkManager with the command:
$ sudo service NetworkManager restart
