I use S1, have about 10 zones, have a ‘connect’ hard-wired to the router, and an apple time capsule connected to that ‘connect’. The time capsule produces its own network which I use throughout the house, using apple repeaters connected via the ethernet port. This all works very well (for many years). We have just changed our Internet Provider, so have a new pre-configured router. The router works, we have Internet and, like the previous one, another wi-fi network that reaches only part of the house. The Sonos system can access Internet services and all the zones are as they should be, but I can no longer access music vis Sonos on the external hard drive. I can still access it and play the music from my laptop! When I try to make a second music library (at the same existing location) within S1, the error message is: the computer  refused to let the Sonos product connect to it. I have tried rebooting all the zones - no effect. I cannot see anything meaningful to change in any menu. Why is the hard disk no longer allowing access from Sonos just because I changed the router (but not the wi-fi)?
