IPv4 I at least understand the basics.  But IPv6 is still magic and 
mystery to me.  I should read up on it I guess.

Really?  <Huff>  'Cause it used to work.  I could open up the Network 
Settings tool, de-select "Wireless connection", select "Wired 
connection", and go to town.

Okay, I guess I'm just hallucinating, but now it seems to be working again.

I restarted the machine and booted from the install cd with the wire 
plugged in.  That found the ethernet device and configured it via DHCP 
and everything worked fine.  Now at least I know that the device is 
still working.

So the next thing I did was restart and boot from the hard drive -- and 
after that the static IP that it was previously configured started 
working fine.

So I turned off the device in Network Settings, removed the static 
configuration, set it back to DHCP, and turned the interface back on -- 
and viola, it worked.

So, just to check, I turned off the wired connection and turned on the 
wireless -- OK.

Then I turned off the wireless and turned the wired back on -- still OK.

I have no idea why this wasn't working for a while, but rebooting seems 
to have fixed it.  (<Gag>:  Reboot to fix?  Too many Windows memories...)

Thanks to all for your help.
