One of my machines here is an old Lenovo Q100 nettop, and after an in-place upgrade from Lubuntu 16.04 to 18.04 the Ethernet networking no longer works.
I've done quite a few web searches, but the circumstances described and suggestions for remedying them vary so broadly I'm reluctant to just dive in and try them all. So coming here for guidance seemed the best bet.
Relevant lshw:

Any tips on what I might try to resolve this? Any other info I can provide to assist your assistance?
This is an old machine and I'm half-tempted to just replace its role with a newer machine I have available here. But I just hate to landfill working hardware, so I'm hoping we can find a solution.
Thanks in advance for any guidance you can offer.
