I just installed both current versions 12.04 and 12.10 of Ubuntu (not simultaneously) and i could not set up an internet connection. The ethernet port on my computer doens't light up when i'm in Ubuntu as it does when i'm on Windows. Furthermore, there is no AutoEth0 option, and when i try to do things manually, it prevents me from being able to save the set up.
And for the life of me i can't find the console where one types the ifconfig command which displays all the info about networking.
The fact that the ethernet port on my pc doesn't light up leads me to believe that the OS or mobo doesn't recognise the port as an ethernet port and maybe i need drivers or the drivers aren't being recognised. Can anyone help? I really want to use this OS because it's the staple for computational chemistry and steam has just made its way there, so i figured i might as well start using it as i'm nearing the end of my undergrad and there are now games to be played there.
In case this helps my setup is the following. gigabyte Z77X-UD3H mobo, i7 3770k OC'd @ 4.7 GHz, gigabyte 7970 Ghz Oc'd to 1.1 Ghz
