Lumin problem

[Donuk]

Firstly apologies to Calloway for hijacking the thread a bit. I thought it might turn out to be the same problem.
But it has been useful and caused me to learn a bit about IGMP snooping and to switch it off on small networks.
That greatly improved the problem but not totally cure it.
I discovered yesterday that Linn have just published a further firmware beta - Davaar 4.56.173.
This, inter alia, addresses an issue that the streamer cannot be found.
Installing this seems, so far, to have cured the problem totally.

Donuk, overcast downtown York.
