Error 651: The Modem (or other connecting device) has reported an error.

Hi everyone,
I'm facing an issue by the time when I wish to use internet via PPPoE connection.
It results me with the subsequent error message saying,
Error 651: The Modem (or other connecting device) has reported an error.

Connecting through WAN Miniport (PPPOE)
Error 651: The modem (or other connecting device) has reported an error.
If you continue to receive error messages you can enable logging for analysis.
Enable logging For logging options, see diagnostics.
Logging options can also be accessed by clicking the Remote Access Preferences menu item under the Advanced menu of the Network Connection Folder
