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.

Is the Era 300 a stand alone Speaker, part of stereo pair or used as a surround?

I guess stereo pair means hooked to music?

my era 300’s are part of my surround system

One of the speakers works as needed. This one particular speaker only blinks a white light. I unplug it for a few minutes- nothing changes.

i press the rear button quickly, and for long presses. Still blinks white.

Ha Ha…

It can’t be a stereo pair and used as a surround at the same time😊. Is it part of a stereo pair that you group to a Sonos sound bar?

If in the room with the soundbar it doesn’t show as below then they are not truly surrounds
