As soon as i start to play music on my sonos system is starts stuttering, literally cannot play more than 2 seconds without stuttering and then I get the buffing error. I have a very simple setup in a small house: Upstairs: Sonos s5, iMac(where music is kept) Downstairs: Router, Zone Bridge. The iMac are S5 are about 3 metre's away from the router(through a wooden floor). My wifi connection for other things on the network is fine and I have never have connectivity issues. I've tried re-installing sonos controller software, assigning IP's to each component in my router setup, I've re-added the sonos system time and time again, change the wireless channel but nothing works. Anyone help me out with this?
