New Era Nightmare

Yes, I’ve done all of these things, truly. After all these efforts were exhausted, I employed Claude, ChatGPT and Perplexity computer to troubleshoot, and they all came back with the same response: either Sonos’s recent software update is problematic or the specific Era 300 device I received has flawed hardware.  Either way, I’m spent on troubleshooting this.  At the price point of Sonos products, they really should be mostly plug-and-play.  This shouldn’t take up so much of my time troubleshooting bad tech.  
 

Sonos, you’ve got 28 days to find a solution here and save a long time customer.  Otherwise, I will be returning this speaker, offloading the rest of my system onto second-hand markets, and leaving Sonos behind.  It would be a shame, since I’ve invested thousands of dollars and nearly a decade to your brand. This is not sustainable though. 

​@Dawntreader1, you need to submit a system diagnostic and call Sonos Support. Don’t post the diagnostic number here. They will be able to see what is happening on your network and/or the problem with your Era 300.

The users here trying to help you are not sonos support. If the first level support isn’t able to help, then escalate to the next level. That’s the only way you’re going to find out what’s wrong.

Edit to add: Just based on your description of the problem, is sounds to me like a packet storm on your network when the Era 300 is plugged in. Which would indicate a misconfigured network. But I don’t have the expertise to help you there.

OK…

SonosNet

None of the newer Sonos products (including some previous releases) are going to recognize the SonosNet:

• Era 100
• Era 300
• Era 100 SL
• Move
• Move 2
• Roam
• Roam SL
• Roam 2
• Arc Ultra
• Sub 4

Zones 

Feature was designed only a year or two ago. The ideal connection is Wired Ethernet to reach each product (see link provided by ​@buzz).

TruePlay

Not an option for the Zones feature. Designers assumed speakers may be in different Zones (Rooms).Trueplay is designed to only work with:

• Individual speakers
• Stereo Pair
• Home Theater (Sonos soundbar, surrounds and sub)

GFiber Google Mesh

• Consists of several configurations (2 to 4 components) and generations
• Which generation/configuration do you have?
• If configured properly each WiFi band 2.4Ghz, 5Ghz and 6Ghz (if available) should have the same SSID.
• If WiFi bands have different SSID’s the Era 300(s) may be connecting to 5Ghz and disappear from your device which is on 2.4Ghz or vice versa.
• There is no need for a personal router if using Google supplied equipment

Bottomline if you are using a Google Mesh system there should be no need for SonosNet as the Sonos products in your profile all should be WiFi only cable. Therefore, there must be:

• A network mis-configuration
• Extreme WiFi interference 
• Out-dated Google Mesh components
• A combination of any of the aforementioned

If you don’t want to deal with the back ‘n forth in this thread (or can't isolate the issue) I suggest the following:

• Do not Factory Reset your speakers (as doing so destroys any valuable data)
• Run a diagnostic within 10 minutes of the next occurence
• Make noe of the reference ID (Do not publish in this thread/community)
• Call Sonos Tech Support to discuss the data

Edit:

Threatening Sonos with 28 days to resolve an issue is not going to buy mileage in this community. You need to contact Sonos Sales/Customer Support. 

Silly to make threats here where Sonos is unlikely to see them but I'll leave you to it and move on.

There is another division of the SONOS company that targets offices, restaurants, banks, and multi-venue installations such as a chain of stores and restaurants. These professional, multi-venue installations can be managed from a central point. The Zones option was developed to help manage large spaces, such as gyms, ballrooms, and multiple small rooms such as customer waiting areas that don’t need special features, such as stereo and surround. I think that Zones was carried over to the consumer side as a convenience for small users who cannot justify the licensing fees of the professional service. (The licensing fees include copyright payments).

With respect to networking, SONOS players must be able to extensively chat and share with each other in order to stay in sync with each other and the controllers. This is a significantly higher load than simply controlling a bunch of thermostats and light switches or even one way online video. A network that is “perfect” for other routine services can be too slow or congested for flawless SONOS operation.

In terms of “congestion”, I live in an urban area. Until a recent move, a WiFi scan could show well over 100 nearby access points. I suspect some of these were drive-by. A scan a few seconds ago only showed 74 access points at my current location. At this level of congestion packets of data will collide and need to be discarded and resent. While this may only require a few milliseconds (for each discarded packet) this can totally destroy music integrity. SONOS does an excellent job of working through this mess, but there are limits to what is technically possible. In spite of the urban mess, I have not been having issues.

Thanks for the tips. 

You cannot separate or manually control the individual Wi-Fi bands (2.4GHz, 5GHz, and 6GHz) to have different network names (SSIDs) within the Google Home app.

Here is how Google mesh system manages these frequencies:

• Unified Network: Google routers are designed to use a single network name across all radio bands, which are kept active simultaneously.

• Band Steering: Instead of allowing manual selection, Google utilizes a feature called "band steering". The system automatically analyzes connections and attempts to route your devices to the best available band based on compatibility, signal strength, and distance.

Basically, Google's design forces all bands to share the exact same SSID

And to clarify, I’m not trying to threaten anyone.  I’m just hoping Sonos or someone can provide a solution before the 30 day return window closes on the new speaker I bought.  I’ve submitted the diagnostic data to Sonos support, so if it leads to a resolution I’ll update this thread in case someone else runs into this craziness. 

Remember, submitting a diagnostic doesn’t automatically generate a response, you must to call in. You may want to read the  Diagnostics - How do they work? thread.

OK…

As far as the 28 days is concerned the mention of that in the community is a moot point. No one that could take that statement to heart monitors this community. It’s better to call Sonos Customer Support to vent that grievance.

Regarding the Google mesh Sonos doesn’t play well with Band Steering or Airtime Fairness active. Reference Band Steering Sonos is smart enough to select the band it needs.

WiFi signal strength isn’t constant as it fluctuates. Having band steering active Sonos isn’t free to jump to a stronger band when there are fluctuations in signal strength. Although band steering may eventually make the adjustment it’s too late for Sonos.

Band steering is effective to balance the load on your network for most devices as they aren’t constantly talking back’ n forth as does Sonos. In short Sonos needs to be free to roam across any band it needs at any given time (ie 2.4Ghz and 5Ghz).

Regarding SSID’s. As a check…If you can physically select either the 2.4Ghz or 5Ghz band on your device then the bands are separated and not unified under one SSID. 

In Continuation of my previous post here’s a Google search on band steering and Sonos

Ok… 

Well this band steering topic is a moot point because Google Home does not allow you to turn that off or physically select bands, and I’m not interested in shelling out more cash and energy to replace my home network because of a new $500 speaker that can’t figure it out when my other 12 Sonos devices (some more than a decade old) and the rest of my home operates just fine on it.

Also, this forum is hosted by Sonos, so there’s no doubt they monitor these threads.  In fact, I’ve found numerous posts about similar issues with the Era speakers where Sonos staff eventually responded.  

I just spent an hour on a chat with a Sonos support rep, after submitting another diagnostic, and by the end I was left with the speaker now stuck in a “not registered” state.  Turns out he had to escalate it to a “specialized team”, and I now wait to hear something via email.
