* I’m experiencing audio playback problems, and getting an error that “Network connection speed insufficient to maintain playback buffer” in the Sonos client on my phone. How do I fix it?

That error message usually indicates some network connection trouble on the system, or trouble with wireless interference. 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 or more between the router and the Sonos channel

Please click the following link to see how to check and change the wireless channel:
