TP-Link AC600 Archer T2U Nano driver for Ubuntu 18.04

For a more stable driver, try this:

    sudo apt install git dkms
    git clone https://github.com/aircrack-ng/rtl8812au.git
    cd rtl8812au
    sudo make dkms_install

For the T2U with ID 2357:011e do

sudo apt install git dkms
git clone https://github.com/jeremyb31/rtl8812au-1.git
cd rtl8812au-1
sudo ./dkms-install.sh

Secure Boot will need to be disabled. The github repo name is a little misleading as the source code supports rtl8812au, rtl8814au, and rtl8821au

With recent changes you will need to

sudo apt install git dkms
git clone https://github.com/aircrack-ng/rtl8812au.git
cd rtl8812au
sudo make dkms_install

This code doesn't include the rtl8814au for that you need

sudo apt install git dkms
git clone https://github.com/aircrack-ng/rtl8814au.git
cd rtl8814au
sudo make dkms_install

Here is a link that addressed issues I was having thanks to an update from Jags: Driver for the TP-Link AC600 Archer T2U Nano, on Kubuntu 18.04 Previous fix from June 6 didn't work for me

    sudo apt update
    sudo apt install dkms

    git clone -b v5.6.4.2 https://github.com/aircrack-ng/rtl8812au.git

    cd rtl8812au
    sudo ./dkms-install.sh
