Hi @ChuckCo, I used a Boost for quite a few years and it certainly improved my SonosNet connectivity. When I updated my Wi-Fi router, I tried a “regular W-Fi configuration” and connectivity to all my Sonos devices was golden … so I retired my Boost.
The ‘goodness’ of the average Wi-Fi router—including those provided by ISPs—has steadily improved over time, all but eliminating the advantage of SonosNet in most cases. As fewer people use SonosNet, fewer still are interested in a Boost.
If your Boost is working for you, offhand I’d stick with it. If you’re in the mood to experiment with a “regular W-Fi configuration,” first verify the strength of your Wi-Fi signal around your home. If you’ve got good strong Wi-Fi everywhere, you can quite likely make the switch and retire your Boost.
There seems to be plenty of evidence that Sonos has been moving away from using Sonosnet - a number of recent and current products don’t use it.
There seem to be some circumstances in which a Boost doesn’t help at all, and it can make wireless network performance worse. I had a stable network (using a Boost) until I added a Move, and that just seemed to screw the whole thing up for anything hi-res (though it was still OK for low-bitrate MP3s). So I removed the Boost and put in a 3-node mesh, which got things stable again.
But I understand your point - why change if the wifi side of your system is performing OK? If you have no problems other than the new app, I’d be inclined to leave it as it is!
