For the adsl, it's better to let Mandrake set it up automatically. When you are in MCC > Netowrk and COnnections > New Connections. Let Mandrake detect it and set it up and on reboot, it should work. As for the browser, i'm not too sure what you mean setting it as default. I just Firefox or Mozilla. As for the shut down problem, not sure either, but I am pretty sure someone else has an answer for that one.
