Setting up file sharing with a wireless router in XP

I can't seem to get my network set up correctly. I have a
wireless router on my PC and I can connect to the internet
on both my PC and laptop. I have set a printer and a file
as shared on my PC, but I get lost when I try to setup the
network unsing the Network Wizard. I moved through it and
created a floppy disk which I used on my laptop. When I
loaded it, it was the same wizard that I just used on the
PC and at the end it prompted me to create another floppy,
which I didn't think was correct. Can someone please help
me step by step? What do I need to do on my PC and then
what do I need to do on my laptop.

Thanks
