Me too, i have Play 3, X2 Play 1, Beam, Move and Roam and its completely screwed up my connectivity via both iOS app and mac controller. Only solution to switch off the 5ghz on the SH2 and wait for bloody BT to get their act together

Sounds like the Boost is pretty much redundant until this issue is sorted out then.

Hopefully BT will pull their fingers out and provide a fix soon!

Forgot to add, i have a Boost too, bought it 2 weeks ago when this started, all worked fine at first and the the roam and move started playing up again and showing up in the 5ghz channel ?? Will keep the boost tho anyway (even the the move and roam dont use Sonosnet) may be useful in future! 

Also experiencing this issue. Can see the firmware on my Hub updated on 8 April. Can I suggest you don’t just report to BT, but raise as a complaint here: https://www.bt.com/help/complaints it only takes a couple of minutes to complete the web form. Hopefully if there is enough complaints they will do something about it quicker. 

on to it now cheers

Like many others having the same issue a couple of questions (from a dumb user)

     -  Has anyone tried giving different SSID’s names for the 5Ghz and 2.4Ghz leaving 5Ghz for TV and moving everything else to 2.4Ghz?

    - I was thinking of buying a Boost but surprised to see this doesn’t work? Wouldn’t it be the same as connecting a speaker by ethernet?

Thanks for all the useful insights 

Can't you have differently ssid's for 2.4gh and 5ghz?, sign all the Sonos kit on to 2.4 (including controller) and all your Smart TV kit on the 5ghz ssid?.

Hi Boost works same way as hard wiring one of the speakers, it creates its own mesh (Sonosnet) independent of the other 2.4ghz band. You can't change the SSID’s on the SH2. Move and Roam dont use Sonosnet and instead stick to the router supplied 2.4ghz band. The issue is that if you are trying to control sonos using an iPhone or device on the 5ghz band, it won't talk to sonos and vice-versa leaving products missing from menus, dropping in and out and just a total **** up really. Best thing is to disable 5ghz from the advanced menu (if sonos is important to you everyday) and wait for BT to sort it - dont forget to file a complaint as mentioned above

Matt,

Thanks that is really helpful - we don’t have a Move or Roam so the Boost would work for us.

As suggested I have a Complaint raised with BT

Thanks a lot

My understanding is Roam atleast, unsure about Move, have 5ghz capability. So Boost should connect to the all the 2.4ghz speakers and normal WiFi pick up Move/Roam. That’s certainly been my experience with Roam, iOS controller can still see it when it can’t see any of the other speakers. 

Sonos have offered a 30% discount on the Boost, but it’s still £70 I don’t really want to spend. I’d never have considered it, as live in a two bed flat and have never experience any Sonos connection issues prior to this BT issue. 

If you have a Roam or Move in the house I wouldn’t recommend purchasing a Boost to work around this issue. In fact, I wouldn’t be recommending an additional purchase just for getting around this issue anyway. Your best option here would be to disable 5GHz on your BT Smart Hub 2 as I’ve described in my original post.

I’ve tried disabling 5ghz and I know it resolves this specific issue, but it’s like solving one problem by creating another one - causing issues for my experience using the internet on other devices. It moves my speed from 150MB down to less than 30MB. This is rubbish when working from home or trying to watch content on the TV. 
 

Has there been anything occur like this with BT historically and if so, how quick are they to respond? I’m considering temporarily moving a speaker into the utility cupboard, I won’t be able to use it, but at least it will help with the connection issues. 

Have filed a complaint with BT. Easily the worst internet provider I’ve ever encountered. 

I’m having the same issues, it’s very confusing as my ipad is connected on 5hz but as it never leaves the house it still has full connection with all devices. both iphones lose all devices. Can’t get through to BT about connection issues as ‘all opeators are busy’

Anyone had any joy on when/if they will get sorted? I was going to get a boost to work around the issue as working from home i cannot disable 5hz

Update

Just ad BT engineer on the phone following me filing a complaint saying they had made some tweaks to my settings and “everything should be fine now”. in addition, they had turned my 5ghz back on. Difficult as i was in the middle of a meeting at the time so didn't have the opportunity to fully investigate. Bottom line is, the problem still remains and ive had to resort to using 2.4ghz only again as the Roam was not connecting to the iPhone iOS 14.5)

Whilst fiddling with the SH2 settings in advanced, i noticed the the iPhone  “Dual Band” setting had “No” selected with no facility to change this to yes, could this be a cause of the issue??

Going to get back on to BT, watch this space

Have we had anymore from Sonos on this?

I am still of the opinion this is more than just BT at fault although I don’t doubt the Smart Hub 2 router may be causing headaches. 
 

The original post states this is an issue to do with devices on 2.4ghz being unable to communicate with devices on 5ghz such as your phone when using the Sonos App. 
However, like I said in my earlier post I was beginning to experience the same issues prior to getting the Smart Hub 2. 
So from my perspective it’s either a bad Sonos update. An issue with the last IOS update. A problem with BT or a combination of them all. 
 

I feel this way as upon further investigation on my setup/network I have a mixture of devices from different companies and ultimately the only devices I can not reliably interact with and control are the Sonos devices (2x Ones and 2x Symfonisks). 

I initially stated that the Amazon Echo Dot 4’s where fine and completely unaffected, and that remains the case, however at the time I didn’t realise that the Dot’s worked on both 2.4ghz or 5ghz so I’ve ruled them out for fairness. (Although why are £50 speakers dual band yet £200 ones are 2.4ghz only? Not a dig as such. Genuinely curious as the the reasoning behind the choice). 

However, at the time of my first post I completely forgot about the Ring camera that’s on the 2.4ghz band and has been completely unaffected by the change to the Smart Hub 2. 
The app works absolutely fine and I have full control of all functions and settings and the camera doesn’t ‘disappear’ like the Sonos speakers do in the Sonos App. 
So if the issue is that the BT Smart Hub 2 won’t let devices on different bands talk, then why can the Ring camera on 2.4ghz communicate perfectly fine with my iPhone on 5ghz yet the Sonos set up completely fails to do so. 
 

Like I said in my original post, it’s seems to me at least somewhat too easy to just blame BT outright. 
 

Happy for someone to pick that apart as I’m no tech person and just stating what’s happening for me. 
 

I would definitely like to hear more from Sonos too. 

Another slight update…

The Sonos One’s are voice control with Alexa set up. 
If I ask Alexa to play something it will also result in the One’s (in a stereo pair) to show back up in the Sonos App/work with Airplay. 
They will disappear again but for some reason using Alexa brings them ‘back’ for a bit. 
 

The IKEA Symfonisks once ‘lost’ from the Sonos App remain ‘lost’ unless I ask the Echo Dot’s to control them. 
 

If I ask Alexa on the One’s to play music on the Symfonisks I just get a ‘sorry, something went wrong’ response. 

Thought I’d add this as hopefully every little bit of information helps someone, be that Sonos or BT get to the bottom of the issue. 

I just tried this. I did manage to play music by asking Alexa. I could then control music through the Spotify App. Unfortunately (for me) the Sonos app still didn’t work. 
 

Good that I can still play music, but it’s infuriating that we’re all having this issue.  

Also, just tried to cast BT sport from my iPhone (5 GHz) to my TV via Chromecast which is 2.4Ghz. Doesn’t work. Confirms it’s a BT Smart Hub issue to me. 

Thanks Mal

Great Detective work, you should be in AC-12

It must be a combination of BT, IOS ans Sonos as my ipad is on 5ghz and works fine. iphone on 5ghz doesnt work. Ring devices on 2.4Ghz work perfectly well with both devices. Very frustrating.

Ny speakers briefly re appear if i leave the house and come back

Interesting. 
 

Whereas the Ring camera at mine works perfectly well being on 2.4ghz and the phone interacting on 5ghz. 
 

I haven’t tried casting anything to TV yet. IIRC correctly they are all on the 2.4ghz band though. 
Something to look into at some point. 
 

I still largely agree this is probably more a BT issue than Sonos but I still think there’s ultimately more to it and it’s more likely a few things not playing nicely. 
 

Something from Sonos would be nice though seeing as we are all basically going around in circles. 

I agree, I have multiple devices and the only ones affected are SONOS.
