Hi There, I have 3 Deco E4R's in a mesh. One main unit, and one wired and one wireless connected as well. I have an Airplay receiver, and are having endless issues with the receiver only appearing intermittently as a selectable destination on my iphone, for example when wanting to play Spotify to airplay receiver. When I connect receiver and iphone to a stand-alone fortinet AP, the airplay works fine. I have tried turning on and off IGMP snooping with no success. Please advise?
