My CR200 is no longer connecting (after a Sonos engineer did some.recent work which fixed another problem). Question: If I do a “Factory Reset Controller” on my CR200, will I lose all my Sonos playlists (after 20 years of painstaking work — I don’t want to even remotely risk this)?? Thank you for any info.
A CR200 will not work in this configuration because it is not a WiFi capable device. The CR200 must use SonosNet which is disabled because neither of your ZP80’s is wired to the network. The original ZP80 design required SonosNet, but over the years the firmware was updated and ZP80’s can now use WiFi. When the ZP80 was updated to incorporate WiFi, CR200 was already approaching EOL and was not updated.
I don’t know why you contacted support. I suspect that a wired network connection of a ZP80 has failed and you are lucky enough that WIFi still works. As a test, power down one ZP80, wire the other ZP80 to the network and try using the CR200. Next, repeat with the other ZP80. Only one ZP80 should be powered and wired to the network. During the test, verify that the ZP80 network port status lights are active. Be sure to try both network ports on each ZP80.
Another possibility is that there has been a physical change in your home and SonosNet can no longer cover the area. WiFi has greatly improved over the years and may now provide adequate coverage for the ZP80’s, but CR200 is stranded (if it’s still working) because it cannot use WiFi.
