Still no luck to install the driver for TP-LINK Archer T2U on fresh installed Ubuntu 18.10. I checked and tried all other posts in here, but I had no luck.

The installation process was like this:

# sudo cp -R . /usr/src/rtl8812AU_8821AU_linux-1.0
# sudo dkms add -m rtl8812AU_8821AU_linux -v 1.0
# sudo dkms build -m rtl8812AU_8821AU_linux -v 1.0
# sudo dkms install -m rtl8812AU_8821AU_linux -v 1.0

After rebooting there was still no Wi-Fi:

Several different chipsets have been used in that product line, so it's possible you aren't installing the correct one. The WikiDevi page for Archer T2U indicates that it's most likely a Mediatek driver that you'll need, not the Realtek one you installed. I've avoided buying these because some chipsets are easier to get working than others, and you can't be sure which one you'll get when you buy them online.
