The guy who lived in my house before me wired every room with ethernet. So I never set up a wireless network. I have a Netgear router hooked up in my study where the DSL comes into the house and where a lot of my other gear is. I have a standard ethernet jack right by my stereo system on the other end of the house. Can I get an Airport Express and not use the wireless feature or the routing feature? I'm looking for a way to play my iTunes on my stereo and I'd like to plug the Airport Express into the ethernet connection and stream my iTunes to it, but I don't get whether the ethernet port will work for that or if it's intended to plug into a hub.
