PCLinuxOs Live CD and the Internet

I have downloaded and have gotten PClinuxOS Live CD
to run on my computer and am very impressed with the
interface.

Two times I have been able to get internet access but I
guess I was lucky those times.

What I thought I did was use the Hardware Configuration
too and configure my setup for ADSL.

I entered the primary and secondary DNS numbers and
chose an internet connection in England. There is nothing
form the US where I am from. I have it set at ppoe.

I also used the Roaring Penguin tool but that did not work
either.

Anyone have any suggestions?

Thanx in advance

Alan
