I have a Asus Eee pc 1000HE mini laptop with 12.04 Ubuntu installed dual booted with xp.
When I plug the LAN cable is it connects fine, I can also reach the router. But I cannot connect to any website. Now I thought it was a problem with the router but here is the strange part: if I connect a other laptop to the same cable it works fine. And if I boot on on the Eee pc from a Live USB the Internet works as well!
If nothing comes up I will try to fix it by reinstalling Ubuntu, but I would prefer if I can solve this in a less drastic way.
lspci -v gives this output about ethernet controllers and network controllers:
