I use my AirPort Express purely for streaming music to. It's connected via ethernet so ***should*** be a pretty darn robust connection yet... It drives me insane as it constantly drops-out. Music will stream just fine for random times, sometimes a whole day or maybe an hour or maybe 5-minutes before the speakers drop-out for no explicable reason. The alert will be "An error occurred while connecting to the AirPlay device “#####”. The network connection was refused." When it drops out both AirPort Utility & iNet Network Scanner will show that it is connected without errors. I'm just baffled. How can it be connected & streaming no problem & then suddenly decide that it will refuse connections from iTunes?
