No NIC after installation / Additional Driver?

[Atlan]

Hi guys,
I just installed Kubuntu 20.04. and I do not have a Network interface nor do I have an audio Driver installed.
From what I was able to find out so far, there should be a tool called "additional drivers" but i can not find it.
Can someone please point me in the right direction, I am searching for it now for an hour.

kind regards
Antlan

sudo kubuntu-driver-manager

It will place an asterisk next to the driver it recommends.

EDIT:
Opps! Sorry, I jumped to an immediate assumption -- video driver.

Open a Konsole and issue
kcmshell5 --list

This gives you a listing of all the tools available. Most, if not all, are in the Settings app.

Search for 'driver' in System Settings if you do not see it there. Otherwise, the Driver Manager will also be found in the Software Sources tool, which can be found via Discover's settings.

sudo kubuntu-driver-manager

This no longer exists (for some releases now). Well, it does, but it is no longer part of a kubuntu install, as it has been replaced by being added to the Software Sources tool - software-properties-qt (shared with Lubuntu)
Don't know why it is still in the repos, as it is frequently broken.

System Settings just has a link that opens the new tool, instead of a KDE specific kcm applet.

kcmshell5 --list

This won't work, unless one has installed the old broken driver manager.
