Arc ultra not connecting

pfff, tried about everything without success, finally factory resetted the whole system again, added sub and era's all to living room, but like last time it adds a speaker in living room 2 and 3 for some reason, finally added the sub and surround to the Arc, then nothing showed up anymore, only 2 empty extra living rooms, rebooted everything again, refreshed the app a couple of times and finally I could see the whole system again, started the trueplay about 5 or 6 times before it finished correctly (sometimes it finished but then gave an error after, sometimes at half the tuning, sometimes didn't even start) and now it seems to work again. Really I have never had such a great sounding system so full of terrible connecting issues….

I don't know if I'm the only one complaining here, but man I think it could/should be so much easier, even the connecting between the speakers and Arc takes forever, no idea why…

Hope I never have to do this again, and if so probably factory resetting the whole stuff would be the best option in the first place I guess, in any case thanks for taking the time to help Rhonny :-)

​@aneet - When adding devices to the system, speakers such as Era 300 will always be put in a separate room initially from the soundbar, as you cannot add just one surround. The surround process requires 2 compatible surrounds hence the naming convention of Living room 2/3.

It is generally recommended to disable Airtime Fairness and QoS on ASUS routers as those are well known to cause connection issues, so I would check your router settings to see the status of those options.

Still some issues unfortunately, even though all is connected, I hear nothing from the sub or surround speakers, I only stream music from my projector or pc (youtube music) via bluetooth, before this worked fine, I got music from everywhere, at the moment only from the Arc, is this a setting somewhere?

I also don't see the trueplay anywhere anymore in case I would want to retune (not so important at the moment)

In the order below…..

Check for updates in the app and run if available 

If problems persist delete the app and reinstall it. 

Select join existing system 

Accept all prompts 

Click the cog wheel in upper right of app on home page

Sign in with your  credentials 

if the problem continues….

Unplug all Sonos 

Reboot your router and let it come back

Plug in all Sonos

Wait 5 minutes after last Sonos is plugged in

Test your Sonos

If problem continues run a diagnostic and make note of the reference ID number

 Call Sonos tech support to discuss the data 

tried everything, even factory resetted everything again, (getting good at it, which is not a positive thing...) but unfortunately no change, no more option to tune trueplay, no sound from sub or era's, only from Arc.

Sucks that there is no email support, haven't got time during the week to call, hope the chat support works...

What is the status of the 2 router options I mentioned above?

I do not know where to find airtime fairness, but I do not use Qos, but just out of curiosity, wouldn't that more likely to affect the streaming quality to the sonos system? As far as I understood the Sonos makes its own 5Ghz network, so it should be able to send to the sub and surround no matter what (unless there is too much interference, but I guess then it would maybe sometimes work and sometimes not)

Airtime Fairness is found under Advanced Settings Wireless > Professional > then around 5 entries from the bottom of the list.

You can disable Airtime Fairness on each wireless band.

ok that was already disabled

The Sonos private 5 gHz link still has to get data from your network and if that is strangling throughput there is nothing the private net can do to fix that.
