Lost Wi-Fi after upgrade to Ubuntu 20.04

Hi, I have a similar problem. I have a LenovaG580 with Ubuntu 19.10 installed. WiFi was operational. Now I upgraded it to 20.04LTS there is no WiFi at all. When check the settings-network only wired option is seen. How can I tell 20.04 about the WiFi availability of the notebook?

Seems to be a common problem, so should be easy to fix.
