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 v5.6.4.1 https://github.com/aircrack-ng/rtl8812au.git
cd rtl*

Package / Build dependencies (Kali)

sudo apt-get install build-essential
sudo apt-get install bc
sudo apt-get install libelf-dev
sudo apt-get install 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 2/3:

$ 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 3 B+ 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

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

You can now control LED behaviour statically by Makefile, for example:

CONFIG_LED_ENABLE = n

value can be y or n

statically by module parameter in /etc/modprobe.d/8812au.conf or wherever, for example:

options 88XXau rtw_led_enable=0

value can be 0 or 1

or dynamically by writing to /proc/net/rtl8812au/$(your interface name)/led_enable, for example:

$ echo "0" > /proc/net/rtl8812au/$(your interface name)/led_enable
