If you have inxi installed, you can also do

Code:

inxi -nia

for comprehensive network device and interface status output.

These are the results of those two commands. I did have inxi installed.

Code:

Note that I have my LAN card installed, but I figured the onboard NIC ought to still show up. I'm not sure if Device-1 listed in the inxi output is that card or not, though, but I think it might be.

Ok, definitely no driver loaded. What happens if you load the driver manually with

Code:

sudo modprobe r8169

You could run the lspci or inxi command again to check status.

It appears to be the MSI oboard NIC with the ' 10ec:8168' chipset. This chipset is included in the output of the 'modinfo r8169' command, and would suggest that it is supported by that driver. However the internet is littered by accounts of those that have found the r8168 driver is required for some hardware using this chipset. In that case, your distro should offer a suitable 'r8168-dkms' package to provide support for it.

A similar thread, where a user required the r8168 Realtek driver...

Yeah, but I can't even find the r8169 module. It's not there anymore -

Code:

(base) base@ryzen7-2700x:~$ sudo modprobe r8169
[sudo] password for base: 
modprobe: FATAL: Module r8169 not found in directory /lib/modules/5.19.0-31-generic
(base) base@ryzen7-2700x:~$ modinfo r8169
modinfo: ERROR: Module r8169 not found.

Should I just install the r8169-dkms package?

You probably need to reinstall the kernel package again. It's one of the many open source modules that should be present.

Did you mean the 'r8168-dkms' package? Install it as per the last link.

Also mentioned here

Let's see if that gets the onboard NIC working.

I installed the r8168-dkms package, and yes, it works - I'm back on Kubuntu for now. I'm going to reinstall those kernel packages.

Thanks for the help. I'll see what I can do about getting the LAN card to work, and post again with my results.

Ok, glad to have been of help. I recommend starting a new thread specifically for the new card when you get to that stage.

I appreciate it. And yes, I am having some issues getting it to work (it doesn't seem to show up), but at least I have my onboard LAN working correctly.

I will start a new thread shortly, as this onboard NIC issue is resolved.
