Still on v0.26.03.01286-BT

I’ve had issues since 10th April (when my router firmware was updated), and I was on 14.4.x at the time… now on 14.5 and still the same. It probably burst back in to life because your phone won’t exclusively live on 5ghz - it will dynamically switch to 2.4ghz if it thinks that’s a more reliable connection. When your phone/controller is on 2.4, you will see your Sonos system.

Sorry to spam the thread.. something you can try that is hours of fun and entertainment: Open your Sonos S2 app; note that your system doesn’t show… turn your wifi toggle on your phone on/off/on/off… after a couple of tries (maybe many), at some point your Sonos system will pop up when your phone drops on to the 2.4Ghz band.

Well the iPad is currently still on 14.4.1 whilst I checked and is currently sat on 5ghz as is my iPhone 11 which is now on iOS 14.5. 
Both are currently able to ‘see’ the whole system and control it. 
My partner (iPhone 11 iOS 14.5) can only see the Sonos Ones which are connected to the WiFi disc but not the Symfonisks connected to the Smart Hub 2. 
My daughter (iPhone 11 iOS 14.5) can’t see anything of the system other than under Airplay but fails to connect. 
 

I fully expect them to drop from my devices soon as well. 
 

It’s all rather annoying. Beyond this I’ve no complaints with BT and the service. My Symfonisks whilst great value considering (bought on a whim whilst in IKEA) have for the last few months been very hit and miss compared to the Ones hence my initial scepticism on it being just BT at fault and were hit and miss whilst on the Home Hub (FTTC) not the Smart Hub 2 (FTTP). 

At this point I’m now beyond caring who’s at fault and just want the system working reliably again. 

Devices will be discoverable, or not, depending on the local traffic path. Different mobiles on different access points, connecting to different speakers on different access points, may see different results. If something blocks all the traffic, or merely multicast traffic, then speakers could go missing.

James, 

Thanks for your advice on the Smart Hub 2 problems.  I had a similar helpful discussion with one of the Sonos agents a few days ago and have since taken your advice and raised a complaint with BT.

I’ve just had a rather useful chat with regard to that complaint that may help other people.  First of all, the problem has definitely been added to their issue log so, hopefully, we will see a fix for the underlying problem at some point.

Perhaps more usefully, I was made aware of another workaround.  It wasn’t convenient for me to plug a device into the router itself long-term as I need my Sonos devices in other rooms; however, if any customers with this router have one of the BT complete wifi discs, it’s possible to plug a Sonos device into that with an ethernet cable. The system then seems to form a Sonos net connection and the connection problems disappear.  This is far more convenient for me as I’m able to site my wired device in the room I want it.  I’ve only tried it for a short time but it’s been stable so far.

I hope this helps.

This will work, as with any other WiFi mesh, but don’t be tempted to wire to more than the one node. The Sonos system will or course depend on the mesh backhaul for internet connection, but mostly this shouldn’t cause problems.

Why am I always loosing my system connection? After turning all my products off then on again and everything connecting I turn my app off and it loses connection so I get this message every time. Please help me, 

What router are you using?

Thank you very much

Hello, I have got four Sonos One, two setup as a stereo pair with a Beam.

All speakers are fully up to date, as is the Sonos S2 (v13.0.5).

I have a BT Smart Hub 2, a Samsung S10 phone, and an iPad to control the system, and most days the app cannot connect to the Sonos system.

My mobile devices, and Sonos products are on the same network, if I connect via wire it connects, but as soon as I disconnect, and drop back to wireless the app is unable to connect again. After maybe an hour and a half the app suddenly finds the products and works perfectly...this happens most days and is inconvenient, what can I do to stop this happening?

No other apps or devices get lost on the wireless network, just the Sonos products.

Kind regards

Daniel

Thanks Ken,

I've made the workaround changes, and also reported it to BT too, let's see how it goes.

Thank you

Hi, recently bought a Sonos Move. It will not stay connected to the app for more than a couple of minutes over WiFi.  I have no other Sonos products.

Every other device on my network works fine

I can get the radio to play by using Alexa, but I would like to control it with the app. 
I’ve followed the guidelines several times including restarting the hub (BT Smart Hub 2) but makes no difference.

I have the same issue with AirPlay 

Any help gratefully appreciated as I’m tearing my hair out here - it shouldn’t be this difficult!

 Thanks 

Hi. iPhones randomly say they can’t see Sonos network, and won’t reconnect. Have tried reboot on router and speaker, uninstalling app, controller reset. Additionally have reset 5 and it says it’s connected but neither phone can see it, then Sonos app says it can’t connect to the app and all the trouble shooting stuff comes up-again! Have even done factory reset, it then works for a short time and back to beginning of phones can’t see network. While all this going on, my Mac can still see and control everything. When I factory reset the phone app said it couldn’t complete registration! But I managed to on the Mac. I have no idea where to start! HELP! please.

It sounds like a router issue.What router are you using?

BT smart hub 2. I did wonder that, but it’s has worked no problem for the past 18 months and the phones connect no problem just can’t see Sonos.

Wow! Thanks! That must be it! Timing is about right and would explain why phones intermittently see Sonos as phones connect on 5ghz. Cheers Alex

Yes I’m having this problem with my Epson XP-8600 as well as my Sonos speakers …. I’ve submitted a complaint to BT

Yes sky go , iPad/phone all stopped working with sky q box about the same time as my speakers .

I too seem to be having this issue. I’ve plugged my Beam into the router but it’s still only showing as my TV now, can’t seem to get Alexa to work on it either. Just wondering as I know people have mentioned 2.4ghz affecting streaming services, does anyone have Sky Sports/BT sports through BT and will it affect that? 

This thread has been so helpful. 
Ever since my smart hub 2 was installed I’ve had Sonos issues and have tried everything. The only thing that has worked is to turn off the 5ghz, which is so ridiculous it’s untrue. I’ve actually got a better router Nighthawk x6 r8000 which would this and other issues I’m having with the Smart hub 2 but BT are blocking it from working. What are BT doing? Crazy. I will not be defeated. 

In the last couple of weeks my two Play1 speakers have been disconnecting from my wifi network between each use of the system.

I have to reset the router to get connection back.

any ideas?

I don’t understand. Turn off the BT WiFi. Make sure the R8000’s WAN/Intenet port is the only thing connected to the BT hub (apart from YouView/IPTV if you have it). Connect everything else to the R8000.
