When pppoeconf is used for Ubuntu ADSL dialing, the network connection may be interrupted and the Network Manager displays that the device is not hosted. The reason is that NetWorkManager conflicts with the networking command and cannot be used together. If you encounter this problem, try:

1. Run in the terminal:

Sudo mv/etc/network/interfaces/etc/network/interfaces_backup

2. Delete dns settings:

Sudo mv/etc/resolv. conf/etc/resolv. conf_backup

3. Restart the network-manager Service:

Sudo service network-manager restart
