If you have a router, or one of the newer DSL modems - do NOT try connecting using PPPoE directly from the computer. You will then be logging in when you are already logged in. The router or DSL modem should handle the PPPoE connection, not your computer. As to why you might not be connecting to the internet from the Linux side, try entering in terminal "ifconfig" and make sure you are getting an IP address. You might even try setting a static IP address and see if that helps the situation. Some (older) home routers can't deal with a computer restarting into another OS. It sees the mac address as the same, but for some reason doesn't like the different OS. Restarting the router seems to help on these. I have seen it mainly on old Linksys routers.
