Hi, coming here last time fixed the wifi, so hoping some one here can also help me get my ethernet problems fixed
In my present location (at work) my ubuntu machine can't connect through ethernet. I can see it, meaning that the ethernet connection is listed as an option when I plug in the cable, however the computer never manages to make the connection and eventually gives up (after perhaps 30-60 seconds). 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.
It is my impression that the following information is called for:
ifconfig:

I have no idea why there seems to be two ethernet connections listed.
Thanks in advance, I hope someone will have some suggestions
EDIT - additional information:
I tried looking at the end of /var/log/kern.lo, 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?
