Ubuntu - Internet isnt working nor popping up

Question

I am COMPLETELY new to Ubuntu, like literally, I only know a few commands and stuff for terminal.. I recently installed it into my laptop to learn it more but for some odd reason my wifi wont pick up, nor will it accept wired connections.. Im currently running version 12.04 and I'm in dire need of assistance. I wish I could give you guys more to work with but im stoked, i have no idea how to fix this. I tried changing my interface settings(gksu gedit /etc/network/interfaces) to

auto eth0 iface eth0 inet dhcp

with was a method i found on google but no luck.. Can anyone help me out please????

-EDIT-

when I type dmesg | grep -i eth i get this
