Ubuntu 20.04 Network not working

I run Ubuntu 20.04, never had any issue like this with this version.

Last time I used the computer was last night, this morning I found out there is not Internet in my computer. I checked the cable and everything is fine, checked my phone and it has WiFi Internet. Checked the router and it's fine.

Checking my computer I can see the network manager only shows VPN and network proxy options, no mention to ethernet network.

I wish I could upload photos.

Any help please?
