after 30 minutes without any change I have rebooted all devices and ran the app again, it again wanted to update, this time it did finish in about 3 minutes, but after that it says some devices not registered to your account, I login, and click register products and it just says no updates requiered, sonos system up to date, when I click finish, again it says not all devices are registered….
After restarting the app all seemed to work, and now also I could retune trueplay, in the end all works again luckily, I hope not that it is like this with every update…
edit: finetuning now does start, but it still ends with an error saying ‘something went wrong, we couldn't finetune your ultra, try again’
After 3 tries it finally worked...
It shouldn’t be like that next time (especially now all seems okay). Sometimes system updates can be unresponsive - but the updates were in fact done…
Sometimes setting static/reserved IP addresses for all Sonos can help update stability issues.
Set on your router DHCP page then power down all Sonos, reboot router and power up the Sonos.
I already did, but like mentioned before I do no longer see the Sub and Era's anymore in the router, sometimes I see them for a few seconds and then they're gone, like mentioned before, I suppose they connect to the Arc and then disconnect from the wifi or something.
But I left the static IP's reserved for all 4.
@aneet
Glad your Sonos is working.
I and @Corry P suggested that you not separate your 2.4hz and 5Ghz Wi-Fi bands. You indicated that it was necessary because certain devices would not connect otherwise. Obviously, you managed to make things work after a lot of trial and error. So once again congratulations!
There is one more factor that could be causing devices connection issues and that is your Encryption Security Level (type). You may have heard or read about them as WPA2 and WPA3. The WPA stands for Wi-Fi Protected Access.
WPA3 is the recommended version to use whenever possible. However it can cause problems for some Wi-Fi capable products. Therefore, there is another level called WPA2/WPA3 which allows connection of devices that otherwise would have difficulties connecting to your network.
That said I suggest you determine if your router is set to WPA3 only and adjust it to WPA2/WPA3. Also, please note that that the options maybe WPA2/WPA3 Enterprise or Personal. You want to select Personal.
All of the above selections are under your routers admin page. If your network equipment is provided by your ISP you may have to get them involved.
Enjoy your Sonos!

You are correct...sort of 
When subs or surrounds are bonded to a Sonos soundbar they theoretically are disconnected from your network as visible units. However, when bonded to a Sonos soundbar they receive commands from the soundbar itself via a proprietary/hidden 5Ghz frequency .
Thanks, I hope it stays working now so I can enjoy the system, the sound is really good. 
I have wpa2/3 personal, cause like you say not all devices can work with wpa3
So...I decided to get a new router, this time I have a separate IoT network that is specifically left at 2G4, and a main network that is combined 2G4/5G, so how to connect everything to the new network?
I entered the configuration, then went to network settings, updated the Arc Ultra just fine, but then tried both the Sub and the Era300's just to get an error all the time, same issues like last time…
It detects the complete system, when I select eg the sub, I hold the phone to the sub, and then I get the error something went wrong and the light turns red, after a while it turns white again, for the Era's, I push both the buttons when asked, after that same error, red light etc.
If I look in the network settings again, it mentions the new network, and all is shown in the system, but the sub and era's do not produce any sound at all, so something is still wrong, do I need to reset everything again or is there something else I should have done??
@aneet
Apologies for not reading everything all over again to this point - but are you adding/did you add the Sub and Era 300s as home theatre speakers via “Add Surrounds” and “Add Sub” in the Arc Ultra’s settings on the Sonos app?

yes, well to be exact I did the last time, and it still shows like that in ‘my system’, I know they will then connect via Sonos own system, but after reconfiguring the netwok on the Arc, the Sub and era's do not have sound anymore, before they did

Can you try ‘Remove Sub’ and ‘Remove Surrounds’ and then add them again to provide a fresh connection to the Arc Ultra?
Yes probably gonna try that, i was hoping not to sober last time this took me almost all day
Edit it is trying to remove them for the last 10 minutes but nothing really happens, don't really understand why it has to take so much time to disconnect something... can't abort either

Hopefully as you have a new router, this will be a straightforward removal and re-addition. The sub and Era300s might be clinging onto old data that is preventing them receiving instruction from the Arc Ultra.
Well i force closed the app and restarted it and then the sub and eras were gone, but when i try to add them nothing is found

Oh maaan. I would suggest force quitting the app again and turning off the Arc Ultra, the Sub, and the Era 300s at the wall, then turn the Arc Ultra back on, let it boot up to white light, then turn the Sub on (to white light), then each Era 300. Then re-open the app and see how things stand...
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)
@aneet
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.
