How to set up a home network?

Hello,

  I'm trying to set up a home network between two computers in my house.  One computer is a Dell Dimesion 8200, Windows XP Home, with a CNet PRO200WL PCI Fast Ethernet Adapter.  The other is a Gateway E Series, Windows XP, with an Intel(R) Pro/100 VE Netwrok Connection.  We are using Shaw Cable, and a D-Link DI 604 Broadband Router.  Both of our computers have internet access through the router.

  I've tried using the Network Wizard, and also the tutorial on HomeNetHelp.com, and other help sections on the internet that I could find, but to no avail.  Can anyone give any suggestions or a link to a site that will show me how to set up the network?  Thanks.
