Archer T4U AC1300 not working

Question

I'm on Ubuntu 20.04, kernel 5.11.0-27-generic. Relevant line of lsusb: Bus 001 Device 003: ID 2357:010d TP-Link 802.11n NIC

As in Ubuntu 20.04 issues with TP Link AC1300 Archer T4U, I installed rtl8812au-dkms package, but wireless internet still doesn't work. Running ifconfig shows no wlan0 interface:

I'm not sure what to do to get this working. Any help is appreciated.

The version of rtl8812au-dkms in the Ubuntu repositories doesn't cover your exact device. I suggest that you do:

sudo apt update
sudo apt install --reinstall git dkms build-essential bc
git clone https://github.com/aircrack-ng/rtl8812au.git
cd rtl8812au
sudo make dkms_install

Unplug and replug the device. You should be all set.
