I had to relocate desktop computer to another room in my apartment. Unfortunately there’s no LAN cable installation there, so I had to use wireless adapter. I’ve bought TP-LINK Archer T4UHP (RTL8812AU chipset) and here I’ll show you how to install driver on Ubuntu 20.04 LTS (Focal Focus).
I’ve googled how to install device on Ubuntu 20.04 and there are several methods (drivers) I’ve found. Only one worked for me, RTL8812AU driver from Aircrack-ng project.
Installation
Installation is quite simple. First we have to install dkms package. Then download driver source and run its installer:
sudo apt-get install dkms
cd /tmp
git clone https://github.com/aircrack-ng/rtl8812au.git
cd rtl8812au
sudo ./dkms-install.shReboot your computer.
You should be able to see Wireless adapter in Ubuntu system tray and connect to desired Wi-Fi network.
