Ethernet not appearing <Solved>

[Piranhamaster]

I am new to Linux. I have plugged an Ethernet cable into both my pc and my router. Nothing has changed from before I plugged in the cable. Any advice on what I could do next?

Also I should add this is a new built system and is not dual boot. Thanks in advance for your help.

Suggest you open Update Manager -> View -> Linux Kernels and Select 5.13 from the left column and the top kernel in the right column then press install. When it's done, REBOOT and see if ethernet is working.

This worked. Thanks to both of you I never would have figured this out myself.
