Can't connect to Sonos error

As your system is currently on S1, this may work. As a rule, however, we recommend not using the Bridge these days - they’re a bit outdated now. It would be a better idea to permanently ethernet-wire one of your speakers. If you do decide to try with the Bridge, you’ll need to start with factory resetting your Bridge.

On BT routers, I typically make sure to disable Extended UPnP Security. This can be found by browsing to your router’s configuration page (http://192.168.1.254) then selecting the following: Advanced Settings » Firewall » Configuration. You’ll need to log in at some point with the detail found on a sticker on your router. Please make sure that normal UPnP is turned on.

Thanks for the tips Corry.

The router UPnP change worked temporarily, like all the others I have made but the iPhone soon lost connection again. I took your second tip and hard wired one of the Play 5 speakers and after that removed all wireless settings from the App. It has been working like a dream since.

However, this is not a solution to the WiFi problem, that is obviously still there for me and others but I was lucky enough to be able to hard wire one speaker and create a Sonos Net mesh channel.

Thanks again for your help Corry.

I’m glad to hear you got things working well - you’re very welcome! Please be sure to keep your Play:5 and router a metre (3 feet) apart to minimise cross-interference.

You may have been affected by band steering on your router - where the router mistakenly identifies Sonos speakers as devices willing to connect to 5GHz when in fact they (some) are not. This can be prevented by having separate 2.4 and 5 GHz SSIDs (broadcasted network names) and not letting Sonos know the 5GHz credentials. This issue would typically result in no controllers being able to connect, however, so perhaps something else was going on.

For those unable to permanently ethernet-wire a speaker there is the Sonos Boost which will create SonosNet near the router without the need to buy a speaker. We would only recommend this if you’ve been in touch with our technical support team and have tried every configurable option. @sonostrip if you’d rather use your BT WiFi and not ethernet, please get in touch with them as they have tools available to diagnose exactly what was happening. For now, however, take the time to enjoy some tunes!

Edit: I just remembered that you can’t actually split the bands on a BT Smart Hub 2.

Hi. I’m not certain - and I haven’t read all of the other questions/replies on this issue - but I may have found an answer. As before, I have an iPhone 11 running iOS 14.4.2. Constant loss of the Sonos app connection to a Play 5 meaning a re-boot of the home Wi-fi to reconnect. If I go to my iPhone settings, WIFi and turn OFF the privacy setting, then the Sonos app connects and works fine. Not ideal as I’m guessing privacy settings are a good thing to have on but at least (so far and I’ve only just discovered this) it means I don’t have to reboot the Sonos connection and my Wi-fi!

Have BT ever produced a router that didn’t have some issue with Sonos gear? Asking for a friend...

I am having the same problem, my windows laptop works fine…. every morning, afternoon, evening and night if I want to use my iPhone to control my system (Sonos S1, running 2 x gen1 play 5s, 1 x Sonos one and 1 x play one) I have to trouble shoot and end up turning my router on and off. I’ve updated my OS, S1 app, changed privacy setting and every other fix possible. THIS IS DRIVING ME MAD!

@Bernard_Donohue 

Thanks for sharing that!

What Privacy setting is that, exactly?

Please don’t get driven mad - I recommend you get in touch with our technical support team who have tools at their disposal that will allow them to give you advice specific to your Sonos system, if the steps outlined above in my second reply (and the thread quoted within) don’t help. If you have a BT router, please also disable Extended UPnP Security, as also mentioned above.

I would contact support but as I work 9-5 mon - Friday that is a bit difficult. Nothing has changed in my set up and until a few weeks ago there was no problem at all. 

Yeah, that can make it quite difficult.

Do you have anything that extends the reach of your router? What router do you have? 

What has changed in the last few weeks? Any new devices in your home?

Do you have a guest WiFi?

Thanks for the reply, I have nothing that extends the wifi, I have BT home hub2, as I stated above, twice.  Nothing has changed in the past few weeks. Below are the things I have done.

Updated Sonos S1 app on all devices, changed Local Network permissions on iOS, turned OFF the privacy setting, disabled Extended UPnP Security.

Nothing works for more than around 12 hours, today I worked from home so didn’t leave the house, same thing this evening. Could not find system but then found system when I turned the router on and off again. 
 

I find it very hard to accept that this is anything to do with my wifi, my old iPhone se running OS14.4.2 works perfectly every time.

My windows laptop also works perfectly.

It is only my new model IPhoneSE running the same OS, 14.4.2 and my partners android phone that have the problem. 

Any more suggestions ?
