Inconsistent failure to connect to Wifi

It’s utterly mysterious and frustrating. Our sonos will one day work, one day not. Will one day connect, and one day show no signs of wifi. Nothing changes in our house. We’ve tried all sorts of rebooting and resetting and restarting and nothing works. It’s absurd. The amount of work we put into trying to get Sonos to work defeats the entire purpose of Sonos. We’ve had it for years, but this is too much. If anyone knows of any obvious fixes, we welcome that. We use the latest iphones and our Sonos 3 speakers and app are up to date. We aren’t tech noobs.

I’m truly sorry you’re having such difficulty. It is unfortunate that Sonos relies on a good network to work well, but without that, you’re going to continue to have difficulty, especially as Sonos uses your LAN in a substantially different way than all the other devices you’ve listed. They’re all mostly ‘device to internet’, whereas Sonos is substantially ‘device to device’ within your LAN to maintain the ability to play in sync, as well as then needing to access the outside internet. 

I would suggest that if you’ve already done what I suggest after a Sonos software update, which is when this router error most frequently is exposed, then you should submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it.

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.

When you speak directly to the phone folks, they have tools at their disposal that will allow them to give you advice specific to your Sonos system and network.

@Salish,

In addition to reserving the speakers IP address in the routers DHCP reservation table, as suggested by @Stanley_4 , I would also certainly opt to fix the routers WiFi channels, as many routers often change channel on update/reboot/startup. I would certainly fix the 2.4Ghz WiFi band to use a non-overlapping channel, either ch1, 6 or 11.

I got home and Sonos wouldn’t work, as usual, despite me getting it to work last night. I did what you suggested and designated the 2.4Ghz band to channel 6, and suddenly it’s working and available to Spotify and the Sonos app. Thank you! Absurd that an over the counter mainstream product would require this level of technical digging to get it to work, but there you go!
