- UBUNTU 20.04
- Bus 001 Device 004: ID 0bda:c811 Realtek Semiconductor Corp.
The good news is that your 0bda:c811 device has support and has been the subject of several answers and duplicates here before; for example: USB WIFI Realtek not an MTP device The bad news is that the previous driver files will not properly compile on Ubuntu 20.04 using a 5.0.0-xx kernel version.
I recommend that you use another method. With a temporary working internet connection, open a terminal and do:
sudo apt update sudo apt install build-essential git dkms git clone https://github.com/brektrou/rtl8821CU.git cd rtl8821CU chmod +x dkms-install.sh sudo ./dkms-install.sh
It builds successfully, albeit with a few possibly harmless warnings, on my 5.0.0-23 system
`sudo modprobe 8821cu`
Your wireless should now be working.
