HOWTO : Install RealTek 8812AU Driver with Packet Injection And Monitor Mode Support

TP-Link Archer T4UHP v1 is also supported by this driver with monitor mode and packet injection. It is a IEEE 802.11ac USB dongle.

Although Kali Linux has its own 8812au driver, I find AirCrack-ng's driver is the best.

Step 1 :

On Ubuntu Desktop 16.04.3 :

sudo apt update
sudo apt install build-essential dkms git

On Kali Linux 2017.2 :

apt update
apt install dkms

Step 2 :

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

Step 3 :

On Ubuntu Desktop 16.04.3 :

Make sure to change at dkms.conf before running the following commands.

nano dkms.conf

Change all "/updates" to "/kernel/drivers/net/wireless" when using Ubuntu.

sudo bash ./dkms-install.sh

On Kali Linux 2017.2 :

bash ./dkms-install.sh

Step 4 :

To remove the dkms driver :

cd rtl8812au

Ubuntu Desktop 16.04.3 :

sudo bash ./dkms-remove.sh

Kali Linux 2017.2 :

bash ./dkms-remove.sh

Step 5 :

To control it, I suggest to use iw wireless tool.

Beware that the driver does not work properly on the following commands :

(1) airmon-ng start wlan0
(2) iw dev wlan0 interface add wlmon0 type monitor

Make sure run "airmon-ng check kill" beforehand.
