Hi Olaf,
Do you have "Stupid Mode = 1" in your wvdial.conf? I think that was missing in 7.3 and may help.
Inserted it into [Dialer <provider>} and [Dialer default] of wvdial.conf. Unfortunately, that's not it. Kinternet's log now gives me this error message: .... ATDT <number> Connect 115200 -> Carrier detected. Starting PPP immediately -> Starting ppd at <date> -> pid of ppd: <number> -> PPP was killed! (signal 11) -> Diconnecting .... I then went into /etc/ppp/options to see if noauth is active. It is. The active options for PPP are: debug, noauth, crtscts, lock, modem, asyncmap0, nodetach, lcp-echo-intervall 30, lcp-echo-failure 4, lcp-max-configure 60, lcp-restart2, idle 600, noipx. In /etc/ppp/peers/wvdial I find: noauth, name wvdial, debug, defaultroute, replacedefaultroute. Any idea? Jutta
