I have a fourteen zone SONOS S2 system connected to a Xfinity XB7 Modem that has the Xfinity Generation 2 Pods connected. The Xfinity XB7 modem has the Wi-Fi selection set to automatic and it appears to be using channel 6, which is the same channel that the SONOS system is on. I have eleven SONOS components connected to TP-LINK managed switches that have been configured for RSTP / STP.
The system can play music from my SYNOLOGY DS1821+ NAS which is running the DSM 7.x operating system. I have a SONOS specific account, and all music has been ripped in the FLAC format. The SONOS S2 system is using SMB3.
On various iPhones (8 and 8 Plus) and an iPad Air whenever we open the SONOS app the SONOS playlist may not be visible. If I force close the app a couple of times the Playlist will reappear. This will last for a short period of time and then it will disappear again. The Playlist will appear all of the time on the various Microsoft Windows 10 Pro computers that I have running the latest SONOS app.
I have also downloaded the Phonos Univeral app for the iPhone and Windows computer and it can locate the SONOS playlist every time. It does take a little time for the icons to display on all of the SONOS playlist.
My wife has created 65 playlists through the years. Is there a limit to the number of SONOS playlist that are allowed?
Currently all SONOS components are getting the IP Address from the Xfinity XB7 modem DHCP pool. Would there be any benefit is assigning the SONOS IP addresses from the DHCP Reserved list?
The SONOS technical support team is scheduled to call me on Friday and work with me again to attempt to resolve this issue which started when I transitioned from S1 to S2.
All suggestions on a possible solution are welcome.
