Enter the PPPoE user name and password assigned by your Service Provider. The Service Name is normally optional, but may be required by some service providers.  Enter a Maximum Idle Time (in minutes) to define a maximum period of time for which the Internet connection is maintained during inactivity.  If the connection is inactive for longer than the Maximum Idle Time, then it will be dropped.  You can enable the Auto-reconnect option to automatically re-establish the connection as soon as you attempt to access the Internet again.More Info
