<< You won't be using the wireless router on the win98 machine directly. You will need to setup internet connection sharing which will basically mean the winxp goes through the router to get to the cable/dsl service. The win98 machine goes through internet connection sharing on windows xp, which you will have to setup, which will then go through the router to get to the internet. It's kind of like going through two routers. You shouldn't have to change anything at all in fact. Just setup ICS on winxp and you'll be fine. >>
you do have to do a little more setup than that because remember the win98 machine will have no access to a DHCP server. This means you get to assign IP#'s, Gateways, Subnet Masks, DNS servers, ect. He is right though as to how it is setup:
Win98 <-cat5-> WinXP <-wireless-> router
