I need some technical help... I have a brand new AirPort Express hooked up to my work's audio system and connected to my work's public wifi network. I am able to stream music from my iPhone 4 to the speakers via AirPlay for literally one second before the audio cuts out but the music keeps playing on my iPhone (w/o audio since it's "connected" to the AirPort Express and the AirPlay icon is still blue). What's wrong with this picture? I even brought my AirPort Express from home and experience the same occurrence. Where is the interference coming from and how do I fix it without having access to settings on my work's wireless router?
