I have found that it is a lot easier to setup the internet connection during the install on the summary page. If you can not get any help, you may want to try it that way. You will need to hit "F1" and then type in at the prompt "expert". Otherwise it will just basically leave it the way it was with a new boot entry. In the expert mode you will have the option to re-install fresh.
Wait and see if you can get some help first. Someone with DSL may can help you with this.
Oh, if you installed the Documentation there is a how to in there that may help. Looks like a life preserver. How appropriate. ha ha ha
Hope you get it going. Wish I had DSL. 24K sucks.
