Managed Switches
Make sure they are programmed to work in Layer-2 mode

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 in 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 consistantly and this may block Linn DS discovery).
  • If you have a simple network with Unmanaged switches, turn "IGMP Snooping" - OFF otherwise check IGMPv2 and IGMPv3 is supported.
  • On BTHomeHubs turn "Extended UPnP security" - OFF
  • On DLINK, within "Advanced", Multicast Streams - ENABLE
