[ubuntu] ubuntu 20.04 WIFI not showing

After installing Ubuntu 20.04 for a week, the WIFI icon has disappeared. Using this command:


lspci | grep Wireless

02:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8821CE 802.11ac PCIe Wireless Network Adapter

I have updated the software using:


sudo apt update


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?
