I think this one can be catagorized as following:
- LAN cable problem
- FC network configuration

First of all, check /etc/modprobe.conf "alias eth0 ..."
If the statement is there, try network configuration again and try to connect Internet.
If network configuration is fine and network is not working,
LAN cable meght be a problem. (before changing LAN cabel, try the cable in other computer.)

if the provider geve you a router for connecting then you should select adsl connection. There you can fill in with username and password.
