I have a B&W Zeppelin air speaker using air play that works fine when first turned on but then stops working after a while. iPhones can't see the air play service from this speaker anymore so I have to turn off and on again. AP is 3602 with 2504 WLC and air play is from wired network. All other bonjour services (apple tv, print services) are working except for this speaker. Any thoughts?
