Ubuntu 9.04: configuration ASDL Tele2 with modem ethernet Atlantis Land

I just installed Ubuntu 9.04 and I had to configure the internet connection ADSL Tele2 (Italy) because of updating the operating system. I have this laptop ASUS modello A6-Q021H, the modem ethernet (that is plugged to the computer with ethernet wire) is the model Atlantis Land A01-AE1. Automatic recognition of the modem has not been successful and it was not helpful to follow this documentazione ufficiale to set ADSL connection.
I finally solved with a wizard launched in the terminal to configure the connection according to the PPPoE protocol.
After connecting the modem to power, phone and laptop, opening a terminal and running:

sudo pppoeconf

wizand will be launched:

Where most options are already set by default so, except username and password of the connection, user will just confirm. In one of the last gray interfaces it's possible to set the starting of the connection at boot-time. Finally, they are indicated the commands to start the connection manually from a terminal:

sudo pon dsl-provider

To close all requests and disconnect the command is:

sudo poff

To control connection status:

sudo plog

For informations about the net inteface created:

sudo ifconfig ppp0
