I want to achieve the same thing with Windows XP that I do with Mac OS X. On my Mac I use "Internet Sharing" from "Wi-Fi" to "Ethernet".
What I'm trying to do is connect my freesat top-set box to my wireless connection. The Freesat box only has a wired ethernet connection.
What I want to do is connect my laptop ethernet connection to the freesat-box ethernet connection and share my laptop's wifi to the laptops ethernet connection
Edit: Also I need the laptop or the wifi DCHP server to address the freesat-box.
