Detecting the Modem
First, I installed gnome-ppp because it provides better control of thedial-up connection:
from a terminal window or through Synaptic Package Manager. This installsautomatically wvdial as the underlying program.
Connect the modem and detect the modem using:
sudo wvdialconf
if the modem is detected save this configuration:
Check using
The modem should appear as /dev/ttyACM0

So far so good. Test the connection.
Click on the the red phone ( the gnome-ppp dialer). Enter user name, password and telephone number as defined with the ISP. Check also the Setup tab and make sure the settings agree with those in wvdial.conf: overwrite /dev/modem with /dev/ttyACM0 to identify the modem. Click on the Connect tab.
Alternatively, you can dial directly with wvdial. Edit the settings using:
sudo gedit /etc/wvdial.conf
Enter user name, password and telephone number as defined with the Internet Service provider. Connect:
In order to establish the connection successfully, it is necessary to start the dialer as superuser from a terminal window:
or
sudo gnome-ppp
For a more convenient start-up icon, add the gnome-ppp icon from the menu to the desktop. Then edit this icon as follows from a terminal
window:
and
change only the following line:
to
Exec=gnome-terminal
-x
sudo gnome-ppp
The following is a /etc/wvdial.conf file that works with the US Robotics USB modem. It is better to use a lower speed and let the modem negotiate a higher speed with the service provider.
New PPPD = yes
