Timur, Please don't use gnome-ppp during setup trials. It uses a hidden config file in your home folder ./wvdialconf Rather use wvdial diffectly when you trying to establish your first CONNECTs. Its config file is the /etc/wvdial.conf In the console in which $ sudo wvdial is initiated, it can be killed with: $ Ctrl-c MarvS On Sat, Jun 12, 2010 at 2:34 PM, Timur Gadzo <gtimur@xxxxxxxxx> wrote: > Just to confirm, disconnections don't occur in Windows. > I use Gnome-PPP to dial and it uses wvdial.
