Oh wait, I just finally got what you mean by wireless hub, and I'm not so sure NATing relates at all. Most everything besides the orinoco ethernet converter (and i'm not even sure about that) is only good with one device on the ethernet side, and that functionality is questionable and usually requires the same brand for everything.

What i'm getting is that you already have an access point, and you want to buy a "wireless hub" that has a wireless uplink and x number of ethernet ports that you can plug things in? You're really in the marget for a "wireless bridge" which is probably going to require 2 seperate netgear ME102's or the equivalent linksys, and you won't end up with any access point for a laptop... I'm over my head here, anyone want to cofirm/deny/modify?
