S2 controller app dropping rooms

It’s definitely a Sonos S2 problem. I don’t want to be bothered to turn everything off and on again every time this happens and it’s happened several times. I think Sonos needs to take a hard look at S2 and provide us an update. This never happened with S1.

Hi - we solved all ourer issues by cabling some of the units - after this everything been rocksolid.

So you ran wires for a wireless system?

Same issues with ‘upgrading’ to S2 controller. For 2+ years on S1 my pairs of 3’s, 1’s and Connect worked liked a charm. Then upgraded to S2 and have had nothing but problems. For over a week I’ve tried to resolve with online, chat and phone support. Everyone keeps telling me to reboot my router, direct connect one of my 3s, direct connect my Connect to the router. Reboot my devices. Reboot my router. I have tried it all with no success. Sometimes my controller (and I have it installed on two laptops as well as my mobile) sees my network, sometimes it doesn’t. Sometimes it sees my network but not all rooms, something its does. Sometimes it sees all rooms but can not connect with all music services (Sirius and TuneIn primarily). Sometimes it plays fine for 5-10 minutes, then drops connectivity. This sounds to me like a software issue but support keeps claiming, no, its a wifi network issue. I have had Xfinity run a full diagnostic on my modem so I know that’s not the issue. Is my only option to keep rebooting the network until it sticks?

I had similar issues. Solved it by disabling the “AIRTIME FAIRNESS” on my Netgear router.  Check your routers and see if they have AIRTIME FAIRNESS enabled or anything that prevent network lag when slower devices connect and disable it.  Worked for me.

I had no problems with my S2 upgrade for at least 2-3 months.  My problems started the exact same day i took on the free trial for Sonos Radio HD.  My understanding is the HD upgrade requires a feature of the S2.   I’m stuck with literally $1000s of Sonos I can’t use.  Only my Sonos move seems to reliability connect.  I’ve also noticed that my iPad had one set of rooms working while my iPhone had a different partially functional list.  This sucks!

I am having the same problem. I upgraded to Sonos 2 and it is now randomly dropping speakers.  Very disappointing. Doesn’t seem like there is a good solution 

I’ll add to this thread - randomly dropping speakers from the controllers but they are still receiving input and playing. Most common is that the living room will only show the ARC and not the surronds or subs (even though the surrounds are defintely playing). It will let you try and add the Subs (and pings to say successful) but doesn’t show - can’t add surrounds. Force closing the app and restarting and they usually reappear but I have no idea what sound is being sent out. Dignostic 780540847. I have done a full reset, was told by support there was a faulty network cable which I have replaced but still happening. 

I’m curious: If you have  the desktop controller installed on a computer can you operate the system using that controller?

I can operate the system - speakers are grouped so I can still do that via the IOS app as well. I can’t access the controls for the Sub / Surround i.e. to alter balance. Its not that I want to do that its more to understand what is going on (for example the app doesn’t show it is broadcasting in ATMOS when this occurs).
