So, in my present location (at work) my Ubuntu machine can't connect to the ethernet. I can see it, meaning that it is listed as an option when I plug in the cable, however the computer never manages to make the connection and eventually gives up. I have no problems connecting to the ethernet at home. Nor is my old computer (also ubuntu, but 12.04) having any problems with this ethernet. At the moment I am connecting to the wifi instead.
From other threads, it seems that this information is called for:

I tried looking at the end of
/var/log/kern.log, and got the following:

while this was going on, the "quarter-circle" icon in the top corner was doing the "wave" animation, meaning that it was working, and at some point a message came up saying "Wired Network // Disconnected" (in two lines). Does that help anyone?
