Max, The output here contradicts itself: I have changed my /etc/wvdial.conf: [Dialer Defaults] Init1 = ATZ Init2 = ATQ0 V1 E1 S0=0 X3 &C1 &D2 +MS=34 Modem Type = Analog Modem Baud = 460800 Modem = /dev/ttySL0 ISDN = 0 Phone = 087305656 Password = Password Username = Username #Init3 = ATX3 Carrier Check = no Stupid Mode = yes But still I get the same problem: ezhik@ubuntu-laptop:~$ sudo wvdial /etc/wvdial.conf [sudo] password for ezhik: --> WvDial: Internet dialer version 1.60 --> Warning: section [Dialer /etc/wvdial.conf] does not exist in wvdial.conf. This part with what you posted above. Put **** in place of password and use username in place of your real username please do the following: $ sudo cat /etc/wvdial.conf make sure that it looks like the one you have posted. You may have a file /etc/wvdial.conf in your home directory. Edit the real one $ sudo gedit /etc/wvdial.conf and make sure it has what you have posted. Also, the version of slmodemd that is running, as you might be running a different one? $ sudo slmodemd --version post it to us. It has to be the one recommended by scanModem. I have checked the requirements of the ISP and they seem kind of normal. Please try to record the session and also post the output of $ sudo tail -f /var/log/messages when you are trying to dialout to see what is happening there? The lines in /etc/pppd/options could also have to do something with what is happening. I wish I knew all the answers, am trying some basic ones . You may take a look at post-install site by Jacques to see if it helps? http://linmodems.technion.ac.il/post-install.html Regards, Antonio PS. Sorry if my ideas are not working, but I am trying to help you troubleshoot the connection. The other options to try would be via livecds and see if you can connect with them and then look at the files in your default installation?
