rtl8821cu wifi

This is with lubuntu 22.04

This will probably need to be done each time the kernel upgrades. **EDIT. with dkms, evidently not necessary.

Details here. But in case it gets lost...

The adaptor shows as: 

0bda:c811 Realtek Semiconductor Corp. 802.11ac NIC

So we build the kernel module:

sudo apt update

sudo apt install build-essential git dkms bc
git clone https://github.com/brektrou/rtl8821CU.git
cd rtl8821CU
chmod +x dkms-install.sh
sudo ./dkms-install.sh

Next, insert it:

sudo modprobe 8821cu
