How to you bridge a LAN and a Wireless device on Windows XP by hand?

How to you bridge a LAN and a Wireless device on Windows XP by hand? Does anyone know how to do it? I have a situation where XP "Network Connection Sharing" isn't working for me. I want to try "bridging" like Vista/Windows7 will do (in the networks control panel). I can do it manually , by hand. Does anyone know the concept of it, or how to do it?
