internet doen't work after update to 16.04

Hey,

I updated my system to 16.04 and it did not end up well.
The graphic card (nvidia) is not working, so I'm in terminal mode.
More important, the inteet is not working, so I can't fix the rest of the problems.

I have coected my machine with an etheet cable, however, I have no inteet.
Please excuse me for using pictures, I can't transfer the log to my laptop.

I tried all kind of solution over the inteet, and I believe that the source of the problem is with the dhclient.

Thank you for the help!

Those are all the screenshots I took:
