PPPoE
Many DSL connections require a PPPoE
connection in order to log in to an internet
connection. Normally, the Easy Detection
Wizard will help you configure that, but
you may manually configure one here.
Consult your ISP for more information
on correctly configuring your PPPoE
connection.
To add a new PPPoE connection, click Edit
Connection List. To choose your preferred
connection, click on Edit Preferred
Connection List.
