Okay, new AirPort Express. After much messing around managed to get it set-up just to run a set of speakers & back-up printer. Problem is this... it keeps randomly dropping off the network. It will stream music fine for hours then... gone, drops out. The light on front will still show green but it's lost as an AirPlay or PortHole streaming option. Only way to get it back up is to power it off/on. The speakers also make a really alarmingly loud electrical type of 'CRACK' noise when the AirPlay stream first kicks in... Any ideas peeps? Is there anyway to look at a connection log from the AirPort Express?
