Airport Utility always gives the dreaded message "Airport Utility was unable to find any Apple Wireless devices..." even though the computer is attached to the Airport Express through ethernet. Using the File--Configure Other I can configure the Airport Express by typing in its IP address. Is that strange or what?? I wouldn't care as much, except that the Airport Express was my very first ever Apple purchase. Also, iTunes doesn't stream to the Airport Express (which I assume is related to the error message). Also, my Dell 1700n network printer does not work with the Airport Express, whether by USB or ethernet.
