Win xp to Win 98

Hello I am trying to connect my laptop with Win XP so that it can share the internet with my home machine that has win 98 (not 98SE). I am trying to use a hub but everytime I try to connect both at once I get an IP conflict for some reason.

Does anyone know how to connect Win XP to a win 98 machine connected the internet using a hug?

thanks
