PPOE is a standard used by DSL modems for the most part. Do you need a user name and password to login, or is it just a direct connect?
Did you set up the username and password for the PPOE login? (Disregard if you dont need that for your DSL provider)
If you have a cable modem, you'll choose either a dynamic or static connection.
Also, do this: Load up your Internet Explorer, click on "tools" then "internet options" then "connections".
In the box, make sure that "Never dial a connection is selected"
That should fix your problem.
