I have an HP EliteBook 845 G8 laptop and recently installed Ubuntu 20.04.3 LTS on it (Windows was previously installed). After installing Ubuntu I can connect to the Internet via Ethernet without any problem, but the laptop doesn't detect Wifi at all (no Wifi tab in Settings).
I can't add Additional Drivers even when I'm connected to the Internet:
Software & Updates: Additional Drivers
Software & Updates: Ubuntu Software - Downloadable from the Internet
More info (in the link the result of the terminal command):

I'm a newbie when it comes to using Ubuntu, but if you need any additional information to solve this problem I'll be glad to post it:)
