Since the release of new software I have been unable to connect to a library of music on a Seagate NAS drive. Sonos support has been on my system at least 5 times. Problem was escalated two months ago with no solution yet. I have a home network with desktop & laptop computers plus 2 smart phones.
I decided to use another laptop to install the Sonos app plus a few selected music library folders and bypass the NAS drive for the time being. I installed the Sonos app on this second laptop. I did so and a surprise! That laptop connected to the Seagate NAS wirelessly and the Sonos system with 5 speakers works!
Then a second surprise the first laptop and the desktop now connects to the NAS while previously (for months and multiple tech calls) it would not.
Perhaps this might help others or Sonos tech support in resolving their problems.
