Starting to lose my patience with this now. I’ve had numerous phone calls and chats, read up on the site forums. Is it just me or does sonos and BT not work?
I’ve tried disabling all security on all devices 
Any help before I stick this lot on ebay and buy something that actually works?
Is it me or the product? 
Is BT British Telecom, or is it Bluetooth? Which Sonos devices do you have? What did Sonos Support say on the phone calls you’ve had?
Which BT kit do you have? There are some known issues:

It’s British Telecom 100MB full fibre broadband. I have an ERA, a MOVE and 4 roams. Sonos support said to remove the roams from the network as they are not designed to be on 24/7. This is surely not correct? My desktop on windows never has any issues connecting via chrome on the /play.sonos.com
It’s a smart hub 2.
The other thing support said was to create a seperate channel becuase my apple watch was on the 2.4 ghz and not the 5. I turned that off and still no luck!
I managed to make it work. I put the 5Ghz off and selected mode 2.

1000MB no 100!!
Right, turned it off… lets see what happens
So am I losing bandwidth now on my router by using a slower channel?
This is firing on all four now isn't it?
This is almost a joke. The app is open before the bloody page even opens now. Assuming this has solved the issue I can’t understand how this took so long to resolve?!
Lesson learnt from my perspective I suppose… Use the forums moving forward!
I notice now that my speed is drastically down when doing a peed test...

Nor can I, FWIW this is what I typed into google to get the links above:
“sonos bt smart hub 2”
Looking at the threads referenced above, it looks as though “Mode 2” is the critical factor. You may be able to turn your 5Ghz band back on after setting up your Sonos devices,
So… It appears its the roams that dont like the GHz… They not responding now. Will keep trying but I think they might be on an older software?
Since switching to the other 5ghz the roams are not responding. Wonder if I replaced these with the new model same issue?
They don’t tell you this s*** when you buy it do they

I’ll tell you what, after a quick reset the roams have “joined” the party… 
they stay.
Thanks for all your help people, appreciated. I will update in a few days once everything is working.
So, it would appear the apple app for sonos does not like 5ghz…? I have now changed it to 2.4 ghz and will see how it goes. The connection issues persisted.
Already after 2 seconds logging into the app now it seems to work straight away.
So, is this is SONOS issue? Now if I want to be able to use sonos from my phone I have to lose bandwidth on my WiFi for everything else in the house? Is it only apple? Is it only BT? Is it only me? lol
This is with 5ghz
This is without…
What are sonos doing about this?
BT devices can be troublesome when used with Sonos. Your first problem turned out to be caused by BT, so why would your problem with speed be exclusively a Sonos problem? Especially since there does not seem to be a massive cry out form BT users on this community, this could also be specific to your situation. If you really want to know what causes this you should make a diagnosis and call Sonos about it.

Doesn’t like your 5ghz perhaps. It works on iPhone with both 5ghz or 2.4ghz here.

The Sonos app on iOS has no issues with using 5GHz.
All my Sonos devices are connected to the router’s 5GHz, except the Arc which can only connect on 2.4GHz.
It’s more likely the BT SmartHub 2 has discovery and communication issues when a controller is connecting over 5GHz whilst Sonos is connecting over 2.4GHz. Similarly, the router could be using band steering and attempting to connect to Sonos over 5GHz, whilst your phone is connected to 2.4GHz. This would again result in devices disappearing from the app as your router can’t effectively pass data when devices are connecting over different bands.
Investing in a better router rather than the free router provided by the ISP would give you a better experience. Even your 5GHz Speedtest is only providing half of the available bandwidth available on your current plan.
