[ubuntu] Can't connect to internet auto eth0 problem

view story

http://ubuntuforums.org – Hi everyone, I saw a few other posts with this problem, but none of the solutions have worked out for me. Bascially I tried to connect to the internet using a cable modem connected to the computer with an ethernet cord. Auto eth0 attempts to connect and the icon spins for half a minute. Then it says that the wired connection was disconnected. I believe this is a linux problem (using lucid lynx) because my friend was able to connect with vista. Any help would be appreciated. (HowTos)
