Realtek RTL88XXAU Driver (sourced from : https://pkg.kali.org/pkg/realtek-rtl88xxau-dkms)

Tested in Ubuntu 20.04 LTS with AWUS1900 (RTL8814AU). Injection working, full driver support. I suggest you use the DKMS install type and reboot.

This repo was made to fill out the space left by the split of these two : https://github.com/aircrack-ng/rtl8812au & https://github.com/aircrack-ng/rtl8814au

None of which provide a RTL8814AU driver with working injection.

RTL8812AU/21AU and RTL8814AU drivers

Only for use with Linux & Android

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 https://github.com/n0ss/realtek-rtl88xxau-dkms.git
cd rtl*

Package / Build dependencies (Debian-based)

$ sudo apt update
$ sudo apt install build-essential libelf-dev linux-headers-`uname -r`

For Raspberry (RPI)

$ sudo apt-get install 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

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 avaiable” in nm-connection-editor. This only works if you have a saved wifi connection.

2. Set interface down

$ sudo ip link set wlan0 down

3. Set monitor mode

$ sudo iw dev wlan0 set type monitor

4. 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
