It takes time setting up work computers. Some might be missed. To accelerate and standardize the post-Ubuntu-installatuion process, I create this post to take notes about the driver, software, and customization.Continue reading “Ubuntu: My Missing Manuals”
There is no built-in support for Realtek RTL8812AU in Linux. To enable, I have to download the RTL8122AU driver source code, compile to a kernel module, and add to the kernel.
Following USB wireless dongles use the RTL8812AU chipset:
- D-Link DWA-171 A1
- Edimax EW-7811UTC
- netis WF2190
- TP-Link Archer T2U Ver 3.0 (RTL8811AU)
For Ubuntu 18.04 LTS and 20.04LTS, follow these steps:
$sudo apt-get update $sudo apt-get install dkms git $git clone https://github.com/aircrack-ng/rtl8812au.git $cd ~/rtl8812au $sudo make dkms_install $sudo modprobe 88XXau
