Jumbo packet/frames networking
This is not an official standard and is not supported by the Linn DS/DSM.

Multicast or Unicast

If you are using more than six Linn DS/DSM products on the same network and want to share/Songcast the music to other rooms, then make sure the LAN can support multicasting.

If you have issues with your Routers, check:

  • QoS is turned OFF (some Routers do not implement this consistently and this may block Linn DS discovery).
  • "IGMP Snooping" is turned OFF
  • On BTHomeHubs turn "Extended UPnP security" - OFF
  • On DLINK, within "Advanced", Multicast Streams - ENABLE
  • "Privacy Separator" is turned OFF
  • "WMM" is turned OFF
  • "Spanning Tree" is turned OFF
  • "Flow Control" is turned OFF
  • Block multicast / broadcast MAC address is turned OFF

  • Speak to a networking specialist who understands the necessary equipment and setup to ensure proper handling of multicast traffic and enable multicast Songcasting
IGMP/IGMP Snooping

If your devices support this service, then make sure this is DISABLED. (This should only be enabled and setup by a “suitably qualified network expert”)
