Long time user here with a new problem I cant seem to get fixed.

I have one room in my system, called Office. I have a stereo pair of Era 100 and a Sub Mini. I have other Era100s around the house and a home theater of an Arc, Sub and 2 Era300s. 

Since the last update, the Office system keeps disconnecting. Everything else works fine. Tried all the regular stuff rebooting routers, unplugging speakers… even tried factory resetting the speakers in the Office room and re-adding. Still cannot get the Office back up. 

Every other device in the house on the network is running fine, even tried moving the Office room speakers to a different room. Nothing works. I can get the speakers connected, but then it will randomly disconnect and be unavailable again. 

Any ideas while I still have some hair left that I have not pulled out?

Is your network just a router and modem or is it a Mesh setup?

Are there any switches and/or 3rd party Access Points (AP) involved?

Also you said you re-added them. When re-adding speakers they must be added as separate rooms with names not used previously in your system. They can be as simple as  “Test One” and “Test Two”. When combined as a stereo pair one of the room names will be used. Add the sub via “add a product” first and you should be prompted to add it to a room. Select the room with the new stereo pair. Next chance the room name to “Office” or whatever you like.

Please answer the questions above as well.

I’m a network engineer by trade, the network is fine. Single router, no noise or interference on channels. Speakers are 6’ away from router. Tried changing to different channels on bot 2.4 and 5Ghz. Tried the new rooms, even tried physically moving speakers to another room.

I get it all reconnected, and it will drop within 24 hours each time.

Again, Ive been using Sonos for years, not a single problem with anything else connected to the system… yet.

Frustrating as hell.

Try powering off all your Sonos, then reboot your router. Wait two minutes for the router to settle, then plug back in your Sonos. Give them a couple of minutes to reboot and reconnect, then check in your controller for any updates, and apply them.

I suspect this will ‘fix’ your issue, but if it doesn’t, I would recommend that you submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it. Don’t post the resulting diagnostic number here, their lawyers get sensitive about GDPR.

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 Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

You may have to wait to get through to Sonos Tech Support. So before initiating the call…As a what if… what if both speakers are left as separate rooms do both or just one drops off? So outside of a defective speaker (or speakers which would be strange) there’s something going on with the network. Make sure Airtime Fairness is disabled.
