The issue is very simple I have difficulties to have internet on my ubuntu machine at home....
I have one laptop running linux mint where I can just plug in the ethernet cable and it works out of the box. But when it comes to the other machine running ubuntu 14.04.4 just plugging in the ethernet cable doesn't give it access to internet.
I don't have access to the router or whatsoever...
Networking experts, what are the steps I should follow to track down the issue?
