Internet Connection Sharing over wireless network with Dialup

Hi-

I have the Linksys WRT54GS Wireless G Router set up at my home with my
desktop and my laptop on the network. My desktop is connected to the
Internet using Dialup and I would like to share this over the wireless
network. I have already performed the steps in Part A here -

and have gotten my laptop and desktop to see each other over the network and
share files fine. I have ICS on on my dialup connection on my desktop and I
ran the Network Setup Wizard to tell my laptop I connect through another
computer but that is where I seem to run into trouble. I don't see anything
different when I do that and so far nothing has changed and it currently
doesn't work. I am using Windows XP Home on the Desktop and Windows XP Pro
on the laptop.
I would really appreciate any help here as this has been troubling me for a
while. Thanks in advance!
