Well, all I can say is now I have full surround and before I did it I did not, and judging from the response time I’ve seen here from Sonos, I’d venture to guess this was the simplest, fastest, and arguably best way, especially on new just out of the box product.

Had as much grief as most on here describe.  S2 app found the ERA 300 no problem, registered the chime but wouldnt connect, 3 re-sets later and a dead end, the app would recognise the button press so had to bale out of the app.

I tried changing the network security specification, shut down the router’s guest network - no success.

Game changer for me on my TP Link deco mesh network was to reset device, then go through the app setup stages until it showed it trying to connect to the network, then use a separate device to turn on the WPS from the mesh device closest to the ERA 300 - BOOM!!  connected straight away.

I had the same problem, reset the Era 300, rebooted, reset the app, etc. All to no avail.

Over on Reddit someone suggested that it was the WiFi security protocol and adding WPA3 to your network caused his to work. On my Eero under eero labs there was a button to add WPA3. The app then immediately recognised the Era 300.

I had the same problem. Here the solution of disabling the guest network is what solved the problem. Thanks to the other user for the suggestion!

This was on a TP-Link Omada system.

I’m having the same problem connecting my EROS 300, frustrated… Tried to call support, waited 2 hours to get someone on the phone that didn’t speak great English and I had to keep repeating myself, hung up… I tried the Bluetooth trick, it didn’t work… My issue is, I get error message saying I need to update my my speakers but when I try to update it says everything is up to date…Help…

I had setup two era100, but the ios app just did not provide possibility to configure them as surrounds. Then i used the windows app…and somehow it registered the era speakers and after that the ios app could pair them as surrounds. 

earlier my arc could not be installed with ios app. Error 1101. Also then the solution was windows app…and ios app after that.

ordinary people dont have skills and passion to find these solutions. Cannot recommend sonos to other than diy people.
