Era 100 stereo pair losing sync

Since the new app was introduced, my pair of Era 100 will not stay in sync. The delay from one speaker to the other keeps increasing. After setup, withing a day when I turn them back on there is an “echo” due to delays. Within a couple of days they get even further apart in timing to where it is totally unlistenable.

If I reset my router, this most often seems to fix the problem, but I don’t want to have to do a twice daily reboot of my router, nor was this necessary at all before the Sonos update to the new system.

If I try to remove the stereo pair and then recreate the pair, then only one speaker will have sound in the pair.

So I end up power cycling the speakers, rebooting my router, have issues with the speakers being found, then finally put them back into a stereo pair, but this is crazy. I have wasted so much time on trying to get these speakers to stay working as a stereo pair. None of the updates have made it any better.

I have tried giving the speakers a fixed IP address assignment based on their MAC, but this didn’t help at all.

As individual speakers they work fine, but that isn’t why I bought a pair of speakers.

I installed a new Asus tri-band router to replace the Telus Actiontec, using “Tri-band Smart Connect” (all bands have the same SSID and password), and the Sonos speakers were reconfigured onto this network and have been working without issue so far.

I can access them from any device connected via 2.4G, 5G, 6E, or Ethernet cable.

So definitely the Telus Router has been the source of my issues.

Hope this helps someone else who is having trouble using Telus equipment.

Hi @MoPac 

Hi @MoPac 

Playing a Bluetooth feed to a stereo pair is possible (when on WiFi) with all Sonos speakers that support Bluetooth, apart from the original Move - it is not capable of communicating via Bluetooth and WiFi concurrently, and therefore cannot stereo-pair when playing Bluetooth.

 Bummer!  My Moves are the originals.  Of course if I had WiFi connected why would I want Bluetooth?

We did learn a few things from our first foray into portable speakers and Bluetooth (the original Move) - those lessons were applied in our later models. The restriction of the Move’s capability is hardware in nature (the radio chip cannot “do” Bluetooth and WiFi simultaneously), so cannot be reprogrammed differently. Our later Bluetooth speakers have different radios.

Bluetooth is actually a pretty handy way of bypassing any Music Library issues - if your entire music collection is backed-up to your phone’s storage, it’s just one more method by which it can be played (apart from Music Library via SMB, AirPlay, Plex, YouTube Music, Apple Music and iBroadcast.com and any others I have not though of).

    Definitely the second router has been set to access point mode since it was installed to avoid address conflicts from DHCP.

    I tried removing the second router (powered it off), but still the problem occurred with dropping out of one speaker.

    I noticed that my phone setting up the network seemed to take much longer to reconnect to the 5G network (hyperbole) compared to the 2.4G network after router rebooting.

    So, I have reconfigured the Sonus system to be on the 2.4Ghz band (hyperbole-24G) as something to try out. I guess the ERA100s prefer to use 5G, I had to disable the 5G band to get the speakers to use the 2.4G band when re-configuring.

    The system did at least stay in stereo through trying all inputs again. (Sonos radio, Spotify service, bluetooth, line-in). The test will be later tonight to see if the drop-out occurs when I use the system again in different modes.

      @Corry P:

       I fortunately have never lost connection to my library, but I can see why some might like to use Bluetooth in their WiFi environment.

       My wish for battery powered speakers is to have WiFi memory, for lack of a better description.  When I connect to a friend’s or relative’s WiFi with my phone that connection is automatic when I return to that WiFi location.  Would be cool if my Move speakers could do the same.  Then Bluetooth in a WiFi environment makes more sense.

      Great! I just wanted to be sure.

      Thanks for trying that - I knew the engineer I’ve been consulting would bring it up, so it’s good I can now say “we tried that and it wasn’t the answer”.

      Interesting. It doesn’t look like the issue is interference - there are a few 5GHz broadcasts around you, but they are all weak.

      I’ll feed this back to my colleague, but please let us know how you get on after a bit of longer-term testing.

      This is already the case. Portable Sonos speakers can keep up to 16 different WiFi credentials in their memory and will automatically connect to any of these that they detect.

      However - there is currently a known issue with being prompted to connect to a new network in the new Sonos app. It may help to sign out of the app and sign back in again, resulting in the Update Network prompt becoming available.

      I hope this helps.

      Just curious here… to get the Move’s onto another WiFi, does that mean they become part of a new system? What happens if there was already another Sonos system on that additional WiFi?

      Hi @Ian_S 

      It depends on what you want to achieve. If you want the Move to be a part of the system on the new WiFi, you would need to factory reset it - a speaker can only “belong” to one system. When you take Move home, you would need to reset it again.

      If you do not want the two systems to integrate, don’t reset anything and the Move and your app will operate independently of the other system. When you take Move home, it will join your home WiFi and still be a part of your overall system.

      I hope this helps.

        Hi @joeser 

        I think you might have found the answer - looking a bit deeper, there is significant interference detected on 5GHz. I don’t know the source (perhaps the speakers are close to a router, access point or another WiFi device), but switching to 2.4GHz may well bypass that issue.

        If the speakers are on or very close to a tile, glass or metal surface, the speakers may be picking up reflections of their own transmissions and detecting that as interference - if this is the case, please try relocating the speakers.

        I hope this helps.

        So far so good!

        This morning I tried all sources and they all still worked.

        I find it a bit strange that I have to be connected to the same WiFi network (2.4G) to use the Sonos app, it doesn’t see the system if I am on the 5G network. The IP addressing should be the same no matter how I am going into the network, so I have to guess the Sonos system isn’t just using regular TCPIP networking? Or somehow the router is blocking traffic between the 2 WiFi bands?

        Also I am not sure how to “find” the system on my PC app now after moving the WiFi band. I don’t want to mess with the setup I have, but the PC app isn’t finding the system even after I do a “reset” on the PC app and “Search for existing system”.

        Great! Glad to hear it!

        Yeah, I find this strange too - but I don’t think we have reinvented TCP/IP! We are aware and looking into it.

        Also I am not sure how to “find” the system on my PC app now after moving the WiFi band. I don’t want to mess with the setup I have, but the PC app isn’t finding the system even after I do a “reset” on the PC app and “Search for existing system”.

        Well, that is strange. If you find the IP address of a speaker from About your System (under Settings, Manage) and ping it from the PC (open Command Prompt and type “ping <IP address of speaker>”), is it able to do so?

        Usually, a PC being unable to connect to a Sonos system means the PC thinks the network connection is Pubic and other devices on it should not be trusted - the fix is to tell Windows that the network is Private, and so trusted:
