I am one of the many who is having total problems with 8.2. Please do not ask what has changed in my home - the problem started with the Sonos update. Please do not ask me to reset my home - I've sequentially rebooted my modem, my router, my wireless unit, my laptop, and all other wireless devices. Please do not ask me to send diagnostics - I am unable to. Please do not imply that this is something that is outside the control of Sonos. Please do not say that you will 'pass along my comments to the development team' ... based on the month-long stream of complaints in the Sonos community site without resolution, they already know about this. Please do commit to a fix or to ability to revert to previous versions.
