Mojtaba, It is best before you make the move completely to gnome-ppp that you use the command line wvdial. It will help us help you better. http://linmodems.technion.ac.il/wvdial.html Use it first, $ sudo wvdial and if you keep getting NO CARRIER, we will try to deal with it with Init Strings, you can add X3 +MS=90, or X3 +MS=34 to your Init 2 string. But first things first. If you can do a script of what you are getting, try this $ script myconnectlog.txt $ sudo wvdial $ CTRL+C -- press CTRL + C key to stop wvdial -- if you could not connect then CTRL+C again or exit and send/attach myconnectlog.txt to us(list discuss@xxxxxxxxxxxxx) and see how we can help from there. > How can I be in your forum?
