"network connection speed insufficient to maintain playback buffer"

I have the same problem and have tried resetting everything in order as advised by others online. This is a painful issue.

Hello Dave and Mark,

That error message usually indicates a connection problem between the device that you're trying to play music off of, and your Sonos system. Do you have problems playing from only one source, such as a music service, or a NAS drive? If you're getting this message when playing off of a mobile device, you're likely experiencing stability issues with that connection. 

We'd recommend starting with checking the wireless channel on your Sonos system and that of your router to make sure the two aren't overlapping. It's best to have 5 channels between the router and the Sonos channel. 

If you're seeing this from a network source, it may be an issue with latency on the network. Can you please submit a diagnostic from your system and reply back with the confirmation number? 

Cheers.

same problem here. Spotify works perfectly on SOnos, but playback from my time capsule constantly cuts off. Problem appeared after updating sonos.

Diagnostic number: 3913171

Thanks for that diagnostic. It looks like your CONNECT is getting a lot of wireless interference. Even though it's wired in, enough wireless can cause the unit to fall behind while trying to pares the wireless for information.

Can you please check the wireless channel on your Sonos system? If you can check your router's Wireless Settings, please make sure the channel there is a good 5 or more lengths between them (try using one of 1, 6, or 11 for each).

Thanks Ryan, for your reply. Sonos is on channel 6, BT Home Hub 4 (the broadband router) is on 1, and time capsule and airport express are both on 11. I have a total of 4 wireless sources, plus I also detect other wireless routers from neighbours, BT Open Zone, etc. BTW, I moved a few albums from the time capsule (also wired) to a WD mybookworld NAS, and they play back on SONOS flawlessly. However, this does not really help me because my music is (and always has been) on the time capsule. moving the entire library to WD NAS is not an option for me. What I do not understand is that everything was fine until I upgraded to BT Home Hub 4. Is there any way I can see the diagnostics results which might give me ideas about how to reconfigure the wireless sources?

You can view a local version of the diagnostic by going to http://:1400/support/review, clicking Network Matrix will show you the to view the signal levels between units. Since just have the one CONNECT, the colors will help the most there, worst is red, then orange, yellow, green.

Is the Time Capsule wirelessly connected back to your BT Home Hub or is it wired in? How is it wired? This could be a latency issue with how the Time Capsule is wired. If possible, wire the Time Capsule into the CONNECT.

Thanks

Thanks for the details and that diagnostic. What format are the tracks from your music library in? It looks like they might be mostly Lossless tracks, is that correct?

I'm seeing a lot of network latency there which could cause issues trying to play high quality streams across multiple rooms.

Can you ungroup your rooms and see if any of those rooms have trouble playing individually?

When you group your players I'd recommend selecting the Group button from the Family Room or Perry's Bedroom if those two are going to be included in the group. The room that was chosen to start the group becomes the coordinator and will be sending the audio to the others. It's best to use a wired player for this in a system with the latency yours has.

Just a few network related questions for your setup there to get a better understanding of where this latency can be coming from:

Where are your Sonos players wired to the network?
What does the network layout look like there?
Is your computer wired to the router directly or another point on the network?

Thanks

Oh yes, Spotify and Internet radio streamed flawlessly - but they are heavily compressed, right? I want CD quality. If we can get this to work, want to install in 2 more homes! Your interface makes my wife very happy. Happy wife= Happy life!

Wiring additional players in your setup there sounds like the best bet for streaming the high quality tracks. Since they're mostly in that central location and can be wired, it's a good practice. We'd usually recommend all to the same switch, but daisy chaining a few can work too. 

Spotify streams at 320kbps which is a pretty high quality stream, radio can be up to 320, but it depends on the station and stream. Your AIFF tracks are likely copied at 1411 kbps which is standard CD quality.

The higher quality takes more bandwidth to transfer and has less opportunity to recover before an error surfaces.

Hope this keeps everyone happy, but let us know if we can help further.
