Thanks for trying this.

Was the IGMP setting that you disabled for IGMP snooping or some other IGMP setting?

After making this change, did you still see that MinimServer was accessible for about 30 minutes after restarting the router and the QNAP?

What is your network setup? For example, are the QNAP and the Yamaha player both directly attached to the router with Ethernet cables or connected in some other way?
