Just done a fresh install of Ubuntu 20.04 LTS on a Lenovo Yoga 530.

I am having issues with my network, it's unrecognised.

*network UNCLAIMED 
  description: Network controller
  product: RTL8821CE 802.11ac PCIe Wireless Network Adapter

UNCLAIMED means Ubuntu is recognizing the hardware, but it needs a driver for it to work. Thanks this card is really common and there is a driver on Github for it.

You will need an ethernet connection and follow this steps on your terminal:

sudo su
apt install -y dkms git
git clone https://github.com/tomaspinho/rtl8821ce.git
cd rtl8821ce
modprobe 8821ce

After completing that steps, you should be good to go, and your card should be working.
