Part 2 of: networking disabled on laptop running ubuntu 16.04 LTS

[M. Fioretti]

Short version: the SAME distro running from the USB stick CAN, indeed 
use the Ethernet

Long version, answering Peter first:

yes, this. In case it matters, (compare this with what I write below)
this is what happened when I just let the live distro boot
normally, it presented me with the two big buttons "try ubuntu"
and "install ubuntu, and I chose the first.

Now answering to Colin:

First, I rebooted hit the ESC key, and chose the "Check disc for 
defects" option.
It reported NO defects.
Next, I selected the "Try Ubuntu without installing" option, and
this time it both loaded and went online without problems. I have right
now the home page of an Italian newspaper, updated 4 minutes ago,
filling the laptop monitor. So now the issue is if/how it is possible
to bring the Ubuntu on the hard disk to the same state (networking-wise)
as the one on the live CD, which is the solution I'd prefer,
or if it makes more sense to just reinstall from the CD.

Thanks,
Marco
