Driver for Debian Based Linux Distros (Ubuntu/Kali Linux)(x86_64)

1. Update the package information :

sudo apt update

2. Install dkms and git :

sudo apt install dkms git

3. Install Build Dependencies :

sudo apt install build-essential libelf-dev linux-headers-$(uname -r)

4. Download the Driver files using git :

git clone https://github.com/aircrack-ng/rtl8812au.git

5. Navigate to the Downloaded directory :

cd rtl88*

6. Install the Driver

sudo make dkms_install

if the installation is aborted , check existing dkms modules and uninstall previously installed driver

👉 Uninstall Existing Driver

7. Check the wireless interfaces by typing iwconfig.

if you encounter any weird interface name , rename the Wireless interface by following below steps

Driver for Raspberry Pi (Raspbian OS / Kali)(ARM)

1. Update the package information :

sudo apt update

2. Install dkms and git :

sudo apt install dkms git

3. Install Build Dependencies :

For Raspbian OS

sudo apt-get install raspberrypi-kernel-headers

For Kali for ARM

sudo apt-get install build-essential libelf-dev kalipi-kernel-headers

4. Download the Driver files using git :

git clone https://github.com/aircrack-ng/rtl8812au.git

5. Navigate to the Downloaded directory :

cd rtl88*

For Raspberry (RPI)

6. 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, then retry building and installing:

export ARCH=arm
sed -i 's/^MAKE="/MAKE="ARCH=arm\ /' dkms.conf

7. Install the Driver

sudo make dkms_install

8. Check the wireless interfaces by typing iwconfig.

👉 Change/Rename Network Interface

Uninstall Driver in Linux

• check the module name and version using the command sudo dkms status.
  

  $ dkms status  
  8812au, 5.6.4.2_35491.20191025, 5.10.63+, armv6l: installed  
  rtl8188fu, 1.0, 5.10.63+, armv6l: installed.```  
  
  

• here module name is 8812au and module version is 5.6.4.2_35491.20191025.

• use sudo dkms remove <module>/<module-version>.
  

  $ sudo dkms remove 8812au/5.6.4.2_35491.20191025 --all  
  
  Deleting module version: 5.6.4.2_35491.20191025 completely from the DKMS tree.  
  
  Done.  
  

• delete this file using sudo rm -rf /var/lib/dkms/8812au/.

Troubleshooting

On Raspberry Pi 4 and Debian 10 image with kernel 5.10.103-v7l+, I get this error.

user@pc:~/rtl8812au $ sudo make dkms_install                    
cp -r * /usr/src/8812au-5.6.4.2_35491.20191025                                        
1dkms add -m 8812au -v 5.6.4.2_35491.20191025

dkms build -m 8812au -v 5.6.4.2_35491.20191025
Error! echo
Your kernel headers for kernel 5.10.103-v7l+ cannot be found at
/lib/modules/5.10.103-v7l+/build or /lib/modules/5.10.103-v7l+/source.
make: *** [Makefile:1786: dkms_install] Error 1

In my case, there is a build directory, but it was empty. I added a symbolic link in /lib/modules/$(uname -r) to the source files as follows:

rm -r /lib/modules/$(uname -r)/build
ln -s /usr/src/linux-headers-$(uname -r)/ /lib/modules/$(uname -r)/build
make dkms_install # now it works
