Problems with Gentoo stage 1 install

First time using Gentoo. I am trying to get Internet connectivity to download source code and install Gentoo Gentoo 2005.1 minimal install

Hardware: Athlon 1900XP 512 megabyte of ram

SBC DSL Linksys WRT54G router

The Linksys is setup with static IP for port forwarding to support an application on a Windows XP box.

I can boot to a Knoppix CD and access the Internet just fine but cannot access using the Gentoo install CD.

I use adsl-setup and enter all required information but when I attempt adsl-start it times out. I have the correct DNS information from SBC.

Thanks for any help Rick
