Your problems are better solved here: https://support1.bluesound.com/hc/en-us/community/topicsI don't know which part you are referring to but the way the review was ended offers the conclusion that the Node is not functional. I wanted to present my own experience that has the same or the very similar start but completely different ending. As I pointed out, my Node is perfectly fine and my router's setting could be incompatible with it. I mentioned the possibility that Amir may have the same or similar problem leading to the conclusion that the Node is broken when it is not.
I don't know if that answers your question. If not, please ask a specific question and I could try to clarify.
The new UI 4.0 has caused many changes and hiccups.
