Just to clarify you are trying for a wired connection right? If you wanna go wireless you will most likely need ndiswrapper.
See here for wireless. http://ubuntuforums.org/showthread.php?t=31926
More info on ndiswrapper.
I think the command lspci will show you needed module info in buntu.
Ubuntu has excellent documentation and I am not a buntu user so I would search their wiki and forums to get you going.
