Is your music cutting out? Or are your players disappearing from the app?

Does it still show up as a ? (how do I make this a question...add another question mark?)

That's an indication that it hasn't gotten a valid IP address from your router. For me, all I had to do was power cycle the SUB, and it picked up the correct assigned IP address.

You may need to try unplugging it, then reboot your router, and once the router comes back up, plugging it back in. This would be the safest bet, but I'll admit I didn't do so on mine.

Oh, it's also possible that there' some wifi interference going on. Read the link, and check around your PLAYBAR and SUB for anything that might be generating interference.

Hi Bruce,

I have tried but still to no avail. Have already switched off all my wireless devices and the Sub still doesnt want to connect. No IP conflicts as well.

Just curious, how can you identify that there are no IP conflicts? None of the routers I've ever used have provided any way to present that kind of information. All they do is present the data of what is connected at the moment in time the report is generated, and never have any information about what other devices might have been connected to the same IP address over the previous X amount of time

Hopefully someone from Sonos will be along to look at that diagnostic, but if you want to hit the support folks, they're on Twitter and Facebook, the moderators here are much more community folks.

My Sonos setup (2x Play 1s, 1x Playbar & 1x Sub on Velop mesh network) has been working great for past 2 months when they were initially setup until 2 days ago, my Sub begin to entirely disconnect itself and dropped out of the group. Under "Room Settings", it will show up as "Living Room (+?+LS+RS)".

I have tried:
1. Re-adding the Sub back via the "Add a Speaker or Sub" from the app.
2. Factory reset my Sub
3. Using ethernet connection instead of wireless.
4. Changing my wireless channels etc.
5. Removing all speakers and redo the whole setup of adding my Play 1s, playbar and sub.

All of the above have failed to resolve the problem. I'm not sure if a recent update has caused this issue. I have checked my Sub and it doesn't seem to have any hardware defects going on since it can be powered on/off and able to be discovered by my iPhone Sonos controller app.

My Sonos Diagnostics number is 136702528

Any help is greatly appreciated. Thanks!

Thanks for sending in the report. I can see the wireless connection between your Playbar and Sub, but your Sub does not have a valid network address. This can be due to IP conflicts, as was suggested above, or other communication issues, such as wireless interference or network congestion. It may be a good idea to set up IP reservations on your network to prevent conflicts.

I do see that there are some wireless communication errors showing up. It may be due to the secondary, unnamed network your router is creating. Both networks are running on the same wireless channel and may be making it hard for your speakers and Sub to stay in communication. Try changing your main wireless network over to channel 1 and see if that helps.

hi Jeff

Thanks for the advice. I will do the above and report my findings soon as im overseas now.

Hi Bruce/Jeff,

Turned out that my router has been switching wifi channels and after I have manually fix them, my sonos setup is working again. Thanks for the brilliant advice and help!

It's good to hear things are working again.

I have two Sonos One's (about two months old) in one room - they are 10 feet from a brand new xfinity wireless router. Up until this week they have been great, but as of this week they are unusable - they intermittently drop connection entirely, stop playing music and won't reconnect for several minutes, they skip songs, airplay works even worse and will only connect and work about 33% of the time. I have changed nothing about them or my room, they haven't moved an inch. I have tried changing my wireless channel on my router to several different channels to no avail, Ive tried resetting them both to factory settings and setting up the room from scratch. Nothing has managed to help. I have no problem chrome casting in the living room, I have no problem streaming music through any outlet. Please help me, this investment has become a pair of paper weights.

This being a weekend, you're unlikely to get a Community Moderator to look at that diagnostic until Monday. If you prefer a more immediate response, I'd recommend that you contact Sonos Support to discuss it. I tend to suggest the phone folks, they have more tools available, but are only available during business hours. Both the Twitter and Facebook support folks are available 24/7.
