rtl8814AU

Realtek 8814AU USB WiFi driver.

Forked from Diederik de Haas' repository which is based on version 4.3.21 of an Edimax driver for the EW-7833UAC device.

Updated with support for kernels >= 4.14 and < 5.3.

Caveat Emptor

This repository is no longer maintained.

If you are thinking of buying a product with this chip in: don't, unless you are prepared to put a considerable amount of work in yourself. More generally, don't buy any hardware that is not supported by the mainline kernel. Some companies claim "Linux support" on the box, on the basis that some third party hosts some (likely unsupported and unmaintained) driver source code for an antiquated kernel version. If you have the choice, look for better alternatives.

Manual build

When building the code, you need to point make to the kernel source and specify the kernel version.

make install KSRC=/path/to/linux-source KVER=x.y.x

This script automates this:

#!/bin/sh
set -e

src=/usr/src/linux
suffix=$(sed -ne 's/^CONFIG_LOCALVERSION="\(.*\)"/\1/p' $src/.config)

ver=$(cd $src; make kernelversion)$suffix
make -j clean all KSRC=$src KVER=$ver
sudo make install KSRC=$src KVER=$ver

DKMS support

From your src dir

sudo cp -R . /usr/src/rtl8814au-4.3.21
sudo dkms build -m rtl8814au -v 4.3.21
sudo dkms install -m rtl8814au -v 4.3.21

This should keep your 8814AU adapter working post kernel updates.
