This version is no longer compatible with the +[install-wifi script](http://downloads.fars-robotics.net/wifi-drivers/install-wifi). +On top of that some versions of the rtl8812au driver I'm using drop IPv6 Multicast, +breaking NDP and preventing you from automatically connecting to the IPv6 internet. +Fortunately aircrack-ng maintains a working version of the driver. However it has +to be compiled from source. Here's how. + +# Kernel Headers +You may need to install the raspberry pi kernel headers. +The apt package name is `raspberrypi-kernel-headers`. +If you're using the 64-bit RPi OS, make sure to install +the arm64 version of the package. +Use `apt list raspberrypi-kernel-headers` to check if you have +the correct version installed. + +# Installing +Run the following shell commands. If you aren't using sudo, run commands that +require root access in some other way. + +```sh +sudo apt update && sudo apt install -y git dkms + +git clone https://github.com/aircrack-ng/rtl8812au.git +cd rtl8812au/ + +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 +export ARCH=arm +sed -i 's/^MAKE="/MAKE="ARCH=arm\ /' dkms.conf + +sudo make dkms_install +``` + +**For 64-bit, these are the commands to run:** + +```sh +sudo apt update && sudo apt install -y git dkms + +git clone https://github.com/aircrack-ng/rtl8812au.git +cd rtl8812au/ + +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 +export ARCH=arm64 +sed -i 's/^MAKE="/MAKE="ARCH=arm64\ /' dkms.conf + +sudo make dkms_install +``` + +If the last command gives an error because the DKMS module already exists, +remove any existing installations of the driver. + +# Loading +The driver should now automatically be loaded.
