Did you by any chance ‘disable WiFi’ on the wired speaker? If so re-enable it.
Thanks ratty, you are a sonos magician. Out of curiosity, the IP of the speakers are still in the same subnet of my router. Is that normal?
No magician. Just someone who has repeatedly observed that the “disable WiFi” labelling in the controller could hardly be more misleading, as it actually disables the radio(s) entirely and hence any ability of the wired device to support SonosNet.
On the second point, yes the IPs are in the same subnet. The wired Sonos device acts as a bridge, not a router.
Ratty I love you man.
You just solved my problem too.
