UPDATE: I turned it into blog post, you can read it here: https://suraj.dev/blog/configuring-wireless-usb-adapter-archer-t2u-nano-on-linux
My T2U has ID 2357:011e
and solution metioned in this SO Thread is for same devide ID
Here is full text of Answer: https://askubuntu.com/a/1149288
# 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
After this I just unplugged and plugged the device again, and it started blinking and adaptor showed up in wifi tab
