Can't connect speakers to Wi-Fi

Been enjoying Sonos for years with only minor issues.  After moving speakers, I’ve been unable to reconnect to WiFi.  I’ve tried unplugging my Network Acces Hub (modem/ router) and all Sonos products, then reconnecting in proper order – no luck.  Factory resets on all products – no luck.

Connecting Play 5 (Gen. 2) with an Ethernet cable has succeeded, but when I disconnect the cable the speaker disappears.  Attempts to enter my correct wireless code, result in an “unable to connect” error.  I’ve succeeded in connecting Era 100 but when I play a song, the icon continually spins…no song being played.

My gut tells me it’s a WiFi/ Network problem, but nothing has changed and it’s worked fine in the past.

When you connected the Play 5 you actually created the SonosNet. The Era100’s will ignore the SonosNet. However if they are grouped to the Play 5 they will play along. 

The other question is “do you have your WiFi bands isolated by different SSID’s?” If so you should place all bands on the same SSID.

If that’s necessary you should

  1. Unplug all Sonos
  2. remove the Play 5 from Ethernet
  3. delete the Sonos app
  4. perform the maintenance on your router and reboot.
  5. Do not factory reset any Sonos
  6. connect your device to WiFi.
  7. Plug in your Sonos 1 x 1 and let them come back.
  8. Do not reconnect the Play 5 to Ethernet.
  9. Reinstall the Sonos app
  10. select Join an existing system
  11. accept all prompts
  12. sign-in with your credentials.

Different SSIDs for each band used to be a way to avoid issues some buggy gear had with more than one band available. Hopefully that is in the past as today we'd need three, 2.4, 5 and 6 gHz SSIDs to deal with it.

It’s relatively easy to move the PLAY:1 and wire it to the network. Try this because it will work around a defective PLAY:5 wireless card.

Another possibility is that the WiFi has been configured to keep the 2.4 and 5GHz bands “isolated” (separate). Each SONOS unit will decide which connection is “best”. If some units are on 2.4 and other are on 5GHz they won’t be able to communicate with each other or the controller if either is on the ‘other’ WiFi band. I don’t know why this would suddenly change, but anything is possible. Maybe there was a PureFiber update. This would have been a very bad idea, causing a flood of support calls. If you factory reset the router, the band sharing may have been altered.
