Notes

Edimax Driver

*A driver for the Realtek chipset of the T4U is provided by Edimax.

However, the USB ID of the TP-Link Archer T4U is not known to this driver.
Therefore, a patched version of the Edimax driver exists, where the USB ID was added.

Open Source Driver

There is also an open source driver under development. This driver can be downloaded from GitHub:

git clone https://github.com/abperiasamy/rtl8812AU_8821AU_linux.git
cd rtl8812AU_8821AU_linux/

As of Oct 16, 2016 this driver contains the USB ID of the Archer T4U.

The driver can be compiled and installed with:

make
sudo make install

If the TP-Link Archer T4U is plugged in, the kernel module rtl8812au should be loaded automatically:
