The Auralic rep just emailed me about router issues they seem to have, a bit concerning.
“We have a lot of customer reporting that routers provided by ISP generally don't work well with high performance streaming, because they may not be able to handle multicasting (SSDP) messages without dropouts, or if your router is blocking certain (IGMP/ICMP) data packets AURALiC Lightning devices rely on to provide the best experience. Some routers (usually lower-performing models supplied by your Internet Service Provider) don’t handle this type of traffic due to their firmware, or, since this kind of UDP discovery data is more vulnerable, a weak network connection will affect this even as your other data connections seem fine.
Please check this article first and let me know if you would like us to further process your order.

I must say you may need to get a Netgear or Asus router for the best network connection quality. Thank you”
