I have a Sonos system that includes:
Sonos Arc Ultra (TV Room)
Sonos Era 300 (connected under a separate room "Era 300")
Both:
Connected to the same Wi-Fi network, with a valid IP (Arc: 192.168.1.102, Era 300: 192.168.1.105)
With the same software version: S2 Version 85.0-64200
Show up on the same system in the app
The Era 300 is disconnected from any group or Stereo Pair, not in the same room as Arc, and ready to be paired
The problem:
When trying to set up surrounds on Arc Ultra, the Era 300 does not appear at all as an option to pair, even though everything is configured according to the instructions.
Steps I tried:
Factory Reset to Era 300 and re-add
Rename room
Disconnect from groups
Update version
Restart all speakers
One network, same frequency (2.4GHz)
