There was only one ‘generation’ of PLAY:3s. Similarly, one generation of PLAY:1s. But that shouldn’t matter. What may be more important is which OS they’re running, if one set is S1, and the other S2, they won’t talk to each other, or be added to a system. 

Factory resets are generally frowned upon, unless instructed by Sonos Support, as it erases all data from the speakers so that Sonos Support has less hard data to look at when suggesting solutions. 

I’d probably also check the WiFi, to ensure it’s set up in the same manner. People like me often assume that it’s just SSID and password, while completely forgetting the channel it is on, or the security settings. And for that matter, the potential for wifi interference , either internal to the network, or external. 

If that doesn’t alter things, were I you, I’d likely connect them again to your router with an Ethernet cable (just to remove one variable), and call Sonos Support directly to discuss it.

When you speak directly to the phone folks, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

Thanks Bruce.  It’s so frustrating. When I first got here I connected all four speakers and they were working just fine. I then switched internet to Starlink Satellite in i had to RENAME my wifi network.  When I tried reconnecting my Sonos system, only the Play 1s connected successfully.  I have tried EVERYTHING but the app can’t connect. It detects the two Play 3s but is unsuccessful in connecting them. 
 

Everything else in my house (computers, video cameras, TVs, refrigerator, alarm, smart lights, etc connected easily. But the freaking Sonos speakers are driving me nuts

Can you, at least temporarily, wire the PLAY:3’s to the network?

There’s a panoply of complaints about StarLink littering these forums. I had no difficulty connecting Sonos to a gen 1 StarLink, but that required factory resetting the Sonos, as the gen 1 StarLink router had no Ethernet ports. My friend got rid of StarLink before receiving any of the later routers/systems, so I don’t have any experience there to rely on. 
 

I can understand your frustration, certainly, and sympathize. I wish I had concrete solutions, but am not a fan of StarLink myself. Too much baggage there, although it is one of three potential solutions in my current environment…just one I’m unwilling to try. Despite owning and loving a Tesla But I’d prefer not to drag politics into this. 

Buzz, what does that mean, with an ethernet cable?  If so, i tried but couldn’t connect.

Thanks again Bruce.  I love the service with Starlink, politics aside haha

What I can’t grasp is why the Play 1s work but the Play 3s don’t. Bizarre

The problem I had (and my friend had) with StarLink, at least in the Pacific Northwest, was a periodic drop in service. About 30 seconds every hour or so. Which isn’t a huge thing for music streaming, in the grand scheme of everything, but is death if you’re trying to manage via Zoom or other video streaming solutions. That drop always seemed to occur at the most inopportune moment. And waiting for reestablishment was just challenging. 

I’m currently using a 5G T-Mobile solution. CenturyLink failed to meet three appointments (while saying they knocked on my door, which they didn’t). And honestly, I’m not even sure I have enough open sky in my location for StarLink…certainly my friend’s house has more than I do.

Hi ​@JMRTEXCOL 

Welcome to the Sonos Community!

Sorry to hear of this issue you are having with getting your Play:3 speaker connected to your new network.

As mentioned, StarLink routers do seem to cause some issues (and are unsupported), but there are steps we can take try to minimise their effects.

Please reboot both your router and the device running the Sonos app. Please reboot your router by switching it off for at least 30 seconds. Next, please ensure the speakers are still flashing green and are ready for set up.

Once all devices have been rebooted, please try again, with an ethernet cable connected between the speaker you are adding and the router, if possible.

If it fails again, please repeat, but with the app on an alternate device, if possible.

If at any point you find yourself with a speaker added but reporting problems, please complete setup/registration/updating from a Sonos app running on a PC or Mac, if that is an option for you.

I hope this helps.

Thanks Corry. Right now I can’t even get the flashing green light on the Play 3 speakers. Tried to do a factory reset without any luck. Any suggestions?  Both speakers were working beautifully before the switch to Starlink but I can’t imagine what Starlink has to do with me unable to get the flashing green light

Hi ​@JMRTEXCOL 

Please try connecting the Play:3 speakers to the router with an ethernet cable, then follow the factory reset instructions precisely. If this helps, you should never need to use an ethernet cable to reset that particular speaker again.

You can let go of the button once you see an orange/white flashing light, but it may take some additional time to change to green - please let it sit for a while if you get as far as seeing the orange light.

I hope this helps.

Will try that now Corry. Will let you know if it works
