If you have issues with your Routers check:

  • QoS is turned OFF (some Routers do not implement this consistantly and this may block Linn DS discovery).
  • If you have a simple network with Unmanaged switches, turn "IGMP Snooping" - OFF
  • On BTHomeHubs turn "Extended UPnP security" - OFF
  • On DLINK, within "Advanced", Multicast Streams - ENABLE
