Elias, Be happy with your one hour CONNECTs. Many modem users have more severe problems. One thing you could do within is edit /etc/wvdial.conf for auto-redial Also read /etc/ppp/options and $ man pppd about decreasing MTU . This sometimes help. Many using Smartlink modems need to do the following before a successful redial: $ /etc/init.d/sl-modem-daemon restart if you have the sl-modem-daemon package installed. These scripts basically do: $ modprobe -r slamr $ modprobe slamr and reactivate the modem.
