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

Build / Install with Make

For building & installing the driver with 'make' use

$ make
$ make install

Using hostapd?

Check the documents folder for more information on how to setup wpa_cli and hostapd support on these drivers.
For 802.11ac (high speed), the driver also needs to be loaded with:
"modprobe -r 88XXau" && "modprobe 88XXau rtw_vht_enable=2"

# For a bit more info on AP/STA mode configuration, see following links:

Download / Build / Install

Download

$ git clone -b v5.2.20 https://github.com/svpcom/rtl8812au.git
$ cd rtl*

Package / Build dependencies (Kali)

$ apt-get install build-essential
$ apt-get install bc
$ apt-get install libelf-dev
$ apt-get install linux-headers-`uname -r`

For Raspberry (RPI 2/3) you will need kernel sources

$ wget "https://raw.githubusercontent.com/notro/rpi-source/master/rpi-source" -O /usr/bin/rpi-source
$ chmod 755 /usr/bin/rpi-source
$ rpi-source

Then you need to download and compile the driver on the RPI

$ git clone https://github.com/aircrack-ng/rtl8812au -b v5.2.20
$ cd rtl*
$ make
$ cp 8812au.ko /lib/modules/`uname -r`/kernel/drivers/net/wireless
$ depmod -a
$ modprobe 88XXau

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

  1. Fix problematic interference in monitor mode.
$ airmon-ng check kill

You may also uncheck the box "Automatically connect to this network when it is available" in nm-connection-editor. This only works if you have a saved wifi connection.

  1. Set interface down
$ ip link set <wlan1> down
  1. Set monitor mode
$  airmon-ng start <wlan1>
or
$ iw dev <wlan1> set type monitor
  1. Set interface up
$ ip link set <wlan1> up

For setting TX power to a fixed index (1=min, 63=max)

$ iwconfig <wlan1> txpower -30
or
$ iw <wlan1> 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 whatever, 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

value can be 0 or 1

check current value:

$ cat /proc/net/rtl8812au/$(your interface name)/led_enable

Testing / Debug

Check "documents" and "tools" folders for information
We also got a Android APK tool for debugging several chipsets

NetworkManager

Newer versions of NetworkManager got some options you might want to disable. Simply add these lines into the NetworkManager.conf

[device]
wifi.scan-rand-mac-address=no

[ifupdown]
managed=false

[connection]
wifi.powersave=2

at the end of file /etc/NetworkManager/NetworkManager.conf and restart NetworkManager with the command:

$ sudo service NetworkManager restart
