Hi,

On refection I think that a little knowledge is a dangerous thing!

When I got the demo unit I turned on Ethernet (DHCP) and turned off WiFi. I then setup Bubbleupnp. All worked.
I THEN noted the 'net' LED was white.

With the new unit I turned on Ethernet (DHCP) and turned off WiFi. I THEN looked at the 'net' LED which stayed on stanby. I suspect if I had just set up Bubbleupnp all would have burst into life.

I could test it ....but I am too busy enjoying the music.
