Is it possible to stream music via AirPlay from an iPhone directly to an AirPort Express without having an active wi-fi connection? In other words, can I simply plug in the AirPort Express to a set of speakers and stream music without having any wi-fi or ethernet connection in the building? I'm having trouble getting AirPlay to work at my place of work. It's set up correctly but when I press play, the connected speakers play my streaming music but only for one second before the sounds cuts out. I am thinking it has something to do with the building's internet connection.
