Here's a little page that might help. There are several out there but this is one of the first ones that I came across:

<a href="http://www.homepcnetwork.com/index.htm?wireintro.htm" target="_blank">http://www.homepcnetwork.com/index.htm?wireintro.htm</a>

You can go to that page and then select at the drop down box at the top which page you want to go to (I just went and looked at the Connect my 2 or more pcs with standard network equipment). Hope that helps a little.

Good luck!
