Thanks Tim. I more or less did all this when the Boost was installed and it never helped the situation at all. It always showed up in the Sonos app as connected and functioning properly. Having said that, there is a real probability that I did something wrong somewhere along the line.
I do think my router is not that great. It is a modem/router combo from the local ISP. So it may have been the source of some of the earlier issues. If the need arises I can get a modem from them and use my own dedicated router but no need at this point.
But, I have taken the Boost completely out of the system. Now I have the Amp, and two other speakers hard wired to the router and so far the system has performed flawlessly. I had to spend a lot of time in the basement pulling ethernet cable and drilling holes but feel it is worth it now.
I don’t know enough about IT or the Sonos architecture to say what the problem was but now the system is working great with the Boost gone.
I have also had some connectivity problems outside of Sonos and they have all disappeared as well now that the Boost is gone.
I really appreciate your thoughts on the matter but given how well things are working I don’t think I’m going to put the Boost back in the system.
