Minimserver offline in Lumin app, but still accessible

That is generally correct, but has nothing to do with the messaging to which Simon is referring.

All streamers use network messaging protocols (and the amount of messaging they generate is very considerable). Your Lumin uses a protocol called OpenHome (a development of the UPnP to which Simon refers), which provides the means by which the server, the player and the controller work together. To do this, they advertise their presence on the network using an arrangement called 'multicast'. Routers often block or limit multicast traffic to prevent it from hogging the network; if this is done too aggressively, your streaming protocols will not work.

Unfortunately, not all routers have settings to control the way they handle multicast, and when they do have settings, they put them in different places and call them different things. I have looked at the manual for your router. Its 750 pages make it the longest, most complex and most impenetrable router manual I have seen. It describes all sorts of esoteric VPN configurations, but doesn't seem to cover basic things like DHCP (network addressing) configuration. So I am afraid that you are correct in saying that the router will not be easy to configure.
