Hello, salman.

At the point where your DSL connection worked fine after you had configured it using Network Manager you sould have simply stopped and enjoyed the working DSL connection.
By using pppoeconf you used a different (old) way of achieving the same goal.
The problem is that it is an either or situation: either you use pppoeconf only, or you use Network Manager only, never both.
So I would suggest to remove the manual configuration done by pppoeconf and return to Network Manager.

Kind regards,
Karl

thank you Karl.....plzz tell me how to remove the manually pppoeconf setting...

Hello, salman.

Acutally, it is been quite a time since I last used pppoeconf. I remember that Network Manager checks a number of network configuration files in order to determine whether they have been changed by another programme. If they have then Network Manager assumes it should not touch the affected networking device.
I will have to locate and launch an ancient Remastersys backup of Ubuntu 10.04 where I last used pppoeconf in order to find out which files tell Network Manager not to manage a network device.
I'll report back ...

Kind regards,
Karl

ok i'ii wait ....bt plzz do as early as possible...i dont know much abt linux...im working on it..thnxx Karl...!!!

Hello, salman.

The key file is /etc/network/interfaces. - Read "man interfaces" to get the details about this file.
NetworkManager will not manage any networking interface which is listed in this file, because it assumes that a different programme will manage it.
pppoeconf will add your networking interface to the file /etc/network/interfaces (and a few other files), thus effectively preventing NetworkManager from managing the interface.
So the approach of allowing NetworkManager to manage your network card successfully again is this:

• Open a terminal window.

• Code: Select all

  sudo poff dsl-provider

• Code: Select all

  cd /etc/network
  sudo cp interfaces interfaces.pppoeconf
  sudo gedit interfaces

  and make sure the file holds these lines only:

  Code: Select all

  # interfaces(5) file used by ifup(8) and ifdown(8)
  auto lo
  iface lo inet loopback

• Code: Select all

  sudo service network-manager restart

• Launch Network Manager and see whether it can manage your internet connection successfully again.

HTH,
Karl
