"network connection speed insufficient to maintain playback buffer"

I wish to add that I am experiencing these issues. This problem started immediately after the most recent updates to the Controller Apps and SONOS components. I have not had this issue previously. Until this update ALL related and connected components have operated properly.

I strictly play from my own music collection stored on my PC, no music renting services nor mobile devices for source.
I use the BRIDGE aka BOOST method and not WiFi.
Playback through: 2 CONNECT:PLAY, 1 CONNECT AMP in my small home.
I have an up to date 802.11 a/b/g/n/ac router that is not showing any other signs of poor performance.

Following suggestions I have changed the channels used by the BRIDGE and have attempted to use the WiFi configuration and am still experiencing this error on all 3 components.

Do note that I have had this system in the BOOST configuration over 5 years and have never experienced this issue before. But, with a previous update I had the issue where the controller app could not connect to my system - no matter what troubleshooting tips I tried. To fix this specific issue I had to delete all controller apps, reset all components then reinstall as new.

During this last update I experienced some noteworthy issues.
On my phone (Nexus6P) the app installed twice consecutively. Immediately upon loading into a "what's new" screen a "check for updates" engaged and forced another update.
On my PC (homebrew Win10 with overly sufficient specs) an initial update took place and 2 days later there was another update required. This 2nd update would not start and did not cite any error codes or specific issue. This is rather common and often I have to delete the controller app on my PC and install new. This is very tiresome.

As SONOS has shifted away from its foundation and has focused more on mobile devices, music rental services and other cloud based content more and more negative situations are happening. I am near the point where I am feeling I wasted far too much on these products that you are making problematic with your updates which are intended to improve the customer experience, not weaken it.

Hi I am having same problems as others with Network connection, never had a problem for 3 years now it’s terrible and have gone back to to playing iPod through a music speaker! Tried all router restarts and reconfigures and no better. Does anyone actually have a solution?

Hi, PJJ. We can certainly get to the bottom of this for you. Following an occurrence of this issue, please submit a diagnostic and respond with the confirmation number. This way we can identify the cause for you. Many thanks in advance.

Hi,
I to am now experiencing the same message. I have submitted a diagnostic 640118914. I am running a boost through a Netgear Orbi router RBK50. I have a play 5, a connect, two play 1s as a stereo pair, and a play 3. The Orbi router was new two weeks ago and no issues with wifi reception. I get 65Mbps download and 18 Mbps upload consistently so no issues with internet speed. I get the network connection speed error whether using my own music library (on NAS) or streaming from Deezer Premium hifi. This particular diagnostic was after numerous errors when streaming deezer through connect. Distance from connect to bridge is 35 ft through two rooms on same floor. Help please?

Not sure if this is the right place to get support...no response to my original post but the problem has got worse to the point my entire Sonos system is unusable. Another diagnostic sent...1239309134.

At the bottom of a multipage topic under "Wireless Speakers" isn't the best spot to post a help request. I'd suggest starting your own topic under the Troubleshooting heading so your post and the responses to it don't get lost in the noise of other folks discussing other issues.

Make it easy for the Sonos staff to find your post and you'll get a faster response instead of a delayed "Sorry I missed your post" a week late.

The other option is a phone call to support which is often needed in any case so they can remote-access your system and poke around inside.

Hi Nary8

You basically have five (5) options...🆒

Option 1
Submit a diagnostic via the Sonos App and post the reference ID in this forum and wait for a response

Option 2
Make sure that your Mesh is broadcasting 2.4 Ghz and that your Sonos is connecting to it

Option 3
A Mesh network can be tricky. First are you using a traditional Mesh such as Google WiFi, Netgear Orbi, Linksys Velop or Ero to name a few; or are you using an AiMesh such as one provided when using two Asus routers such as the RT-AC1900 in conjunction with an RT-AC1900 for example?

In either case I suggest you check to see if “Airtime Fairness” is enabled and disable it. Airtime Fairness can have a negative impact in certain environments where there is a mix of clients. You can read more about Airtime Fairness (positive and negative) at the link: https://routerguide.net/airtime-fairness-on-or-off/

Option 4
_Unplug your Sonos
_Unplug all clients
_Take down your Mesh and reconfigure it (make sure 2.4 Ghz is broadcasting)
_Setup your Sonos one-by-one
_Set up other clients one-by-one

Option 5
Setup Sonos in Boost mode. Click the Link: https://support.sonos.com/s/article/3235

Please post back with your results. Cheers!

Just as a note for others following this thread, in almost all cases, this message is not a reflection of the speed of your modem to the internet, but instead the speed between your local Wi-Fi router and the speakers themselves.
