Driver Information
Developed internally by Realtek, and then patched by open community members.
This drivers is not mainlined (might never will be, from the look of it), so you’ll be loading a self-compiled out-of-tree kernel module. If you are running on a system using UEFI Secure Boot, you may need to either disable Secure Boot or sign the kernel module before you can load it. (We won’t cover that here.)
To check the status of Secure Boot, run
|
1 |
mokutil --sb-state |
Output will be one of the following:
SecureBoot enabled— using UEFI, Secure Boot enabledSecureBoot disabled— using UEFI, Secure Boot disabledEFI variables are not supported on this system— not using UEFI, Secure Boot disabled
Driver Installation
Kali Linux
For those who are running Kali Linux ARM Image on Raspberry Pi, the driver should be installed already.
For x86 users, installed package realtek-rtl88xxau-dkms.
Note that because the kernel module is built with DKMS you should ensure you have installed and rebooted to latest kernel update before installing.

sudo apt update sudo apt install realtek-rtl88xxau-dkms |
Parrot OS
Security edition has package realtek-rtl88xxau-dkms installed by default. If this is not the case, follow the instructions above for Kali Linux.
Debian and Its Derivatives
Debian, Ubuntu, Linux Mint, elementary OS, etc.
APT is able to install local deb file since version 1.1 — we can use that to install realtek-rtl88xxau-dkms from Kali.
First, find the latest realtek-rtl88xxau-dkms deb package from Kali’s repository.
At the time of writing, the latest one is realtek-rtl88xxau-dkms_5.3.4~20200115-0kali1_all.deb.
Note that because the kernel module is built with DKMS you should ensure you have installed and rebooted to latest kernel update before installing.

wget https://http.kali.org/kali/pool/contrib/r/realtek-rtl88xxau-dkms/realtek-rtl88xxau-dkms_5.3.4~20200115-0kali1_all.deb sudo apt update sudo apt install ./realtek-rtl88xxau-dkms_5.3.4~20200115-0kali1_all.deb |
Although not tested, some distros should be able to perform the whole process in GUI — download deb package through browser and double-click to install.
Fedora
|
1 |
sudo dnf install dkms kernel-devel make |
Note that because the kernel module is built with DKMS you should ensure you have installed and rebooted to latest kernel update before installing.

git clone -b v5.3.4 https://github.com/aircrack-ng/rtl8812au.git cd rtl* sudo ./dkms-install.sh |
Arch Linux
These instructions are expansions of
|
1 |
sudo pacman -Syu --needed base-devel git dkms linux-headers |
If you’re not using the default kernel, package linux-headers should be changed respectively. Say you’re using LTS kernel, the command would then be
|
1 |
sudo pacman -Syu --needed base-devel git dkms linux-lts-headers |
Note that because the kernel module is built with DKMS you should ensure you have installed and rebooted to latest kernel update before installing.

Appendixes
Getting package URI
In case that repository URL changes in the future, spin up a Kali VM or even a Docker container, and run
|

sudo apt update apt download --print-uris realtek-rtl88xxau-dkms |
Monitor, Injection Support
May not work on distros other than Kali, which is specifically tweaked for pentesting.
