I have a desktop computer that dual boots into Ubuntu Studio and

After the last update and rebooting, it turns out that I no longer
have ethernet on Linux. This is not true on Windows, as I am writing
you this email from the same computer.
I strongly suspect that there is an update issue that is disabling
ethernet on Linux. Right now, my computer is in splendid isolation
from the rest of the world. I can't even see computer resources from
other computers in my apartment. I also can't see the router itself
through my browser.
Any ideas as to what to do next to diagnose the problem?
I'd start with the network manger GUI, see if you can see anything
obvious there, and if not, start debugging from the command-line.
In a previous life, I found the instructions for disabling network
manager contained a lot of useful information.
If you take that route, use script(1) and a notepad to carefully
record your steps, as a lot of networking stuff is sensitive to the
order you do things in, and you want to make a good map of where you
went, for the time when you want to undo the changes you made.
Oh, and make a backup of your home directory if you haven't already
