So for the Windows dailer do you have to provide a user and password.
Then this is the info needed for NetworkManager.
The comment about usb is for the gnome / kppp dailers.
Here is the solution according to the poster in the artical.
Edit the network connection go DSL option and clicked the add option
Put the required user name and password and kept the service name blank
in PPP setting I removed all authentication option saved and restarted the Ubuntu.
Still it was not working then I kept the 'CHAP' option ticked, removed all other and restarted.
Still it was not not working then I again tick all the option and it was working.
Remember: Tick the Connect automatically option on in both wired and dsl tab
