Ok, I took a look at the logs on my Essence and my A6. If there is a network problem I would think it would affect all at the same time. My Essence "popped" 3 times that I am aware of today (I could search the log to find all the occurrences, but here is the log entries: (last occurance)
Essence

BeoSound 2
This is not happening on the BeoSound 2. I typically don't hear this "popping" from it.
As you can see from the log times, it doesn't happen at the same time on the Essence and A6.
