1 of my Era 300 speakers will no longer connect to wi-fi. I press the button on the back. Light continues blinking white. Never turns blue. I have unplugged . Updated all Sonos products. 1 speaker will not connect.

The Bluetooth button on the back will not help the Era 300 connect to Wi-Fi. A blue LED means that it is connected over Bluetooth or in pairing mode when it is flashing blue, but Bluetooth is disabled when being used as a surround.

If you are not having any trouble with your other Sonos devices, I’d factory reset the missing Era 300 and add it back to your system.

You would need to select remove surrounds, then add the surrounds again when both are visible in the app.

If after you get everything sorted and it happens again just unplug all components for that room. Wait 5 minutes an plug in the Arc first and let it appear in the app. Next plug in the surrounds and let them re-connect to the Arc. Last plug in the sub-mini and let reconnect to the Arc.

    When both Era 300’s were connected- that’s what my app looked like. Now it only shows 1 Era 300.

    When used as a surround system, the Sub Mini and Era 300s connect to the Arc over a private 5GHz network.

    Is there anything near the missing Era 300 that would interfere with the wireless connection between it and the Arc?
