After installing Ubuntu 20.04 for a week, the WIFI icon has disappeared. Using this command:
Code:
lspci | grep Wireless
returns
02:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8821CE 802.11ac PCIe Wireless Network Adapter

I have updated the software using:
Code:
sudo apt update
Code:
sudo apt upgrade
and restart but the WIFI icon is still missing. My home WIFI works fine.

Any idea on how to solve the internet connection?
