Honestly you don’t need to post multiple times. The frequent users of the community will view Recently Active Topics so they see all posts made. Plus, my last post subscribed me back to the thread, so I did get your email notifications too.

Ha, I bet you were hoping each time you opened the app that it would show a connection error!

Happy to hear that works for you. You will know how often you had connection issues, but hopefully over a prolonged period your system is more stable in this setup.

Next issue to troubleshoot is if you need to enable 2.4GHz for other devices, and/or the 5GHz isn’t giving good coverage in your household.

hello Mr T

thank you for your help.

i was not hoping for a non connection issue no, I promise you . I just want it to come on so i can play my music when I want to from where i want to in the house. I’ve had enough non connection issues - thank you. 
 

I was so excited when I purchase this years ago and I’ll be honest it’s a great sound. (And that’s coming from someone that spends £3.5k for Rockford fosgate for his car) 

it has been frustrating at times and perhaps I’ve vented a bit in here too (oops) my bad

point is, it’s doing what it says on the tin now thanks to you. 
 

the only thing I see connected to 2.4 is my watch so will need to see what that’s all about 

thanks pal, I’ll be sure to leave a glowing review kn here with thanks to you and your team. 
 

Not sure who you are or who you work for but ta

The regular posters on the forum like myself are just other Sonos users, wIth a couple of Sonos mods overseeing the community.

I don’t even work in IT. Reviewing posts in this community helped me around 5yrs ago when I had an issue playing Sonos Radio HD.

After learning how Sonos actually worked, I stuck around to help other users.

I’m sure you are relieved now you have a Sonos system that works with your router!

Enjoy listening to your music!

Thank you nice one. We need more people like you in the world.

The official Sonos posters almost always have a 'Sonos Staff' tag following their user name. 

Well that lasted long…

Try force closing and reopening the app.

Did you enable 2.4GHz band again?

Edit: In addition to the actual BT Smart Hub 2 router, do you have any extenders/boosters?

No to 2.4 and extenders 

In a post above you said 

What is your watch connected too?

Your system should always at least connect to the Era speaker [when using 5GHz only] if you never disconnect it from power, whereas Move and Roam will depend on whether they are powered on. After a period of time, portables will enter sleep mode, then power off, although you can amend the Battery settings in the app.

Actually from a Search, this thread suggests there is an inherent problem with some BT Smart Hub 2 routers. 

I’d therefore ask BT to send you a replacement and if that still has issues, buy your own router to use instead.

I can’t remember, or bother to plough through 5 pages, so apologies if it’s already been asked/suggested:

   1 have you tried running with set ip addresses?

   2 as there was an acknowledged BT issue before, have you spoken to BT to see if they have any suggestions? 

Ha, no and no...

I’d be installing my own router, changing or disabling the BT WiFi, and moving any wired network clients to the new router. The new router will be the only wired client of the BT. Keep all of your network clients powered down (or in Airplane mode), except the phone/pad/computer you are using during setup, until you have the new router configured and operating.

I just stumbled over this thread:

Interesting … first time I saw that

Hi ​@schnawl 

Welcome back to the Sonos Community!

I’m sorry to hear of the issues you have had with connecting to your Sonos system on your BT Smart Hub 2.

The ”wireless mode” setting at the bottom of your router settings screenshot needs to be changed to Mode 2:

I also recommend that you turn off “Smart” channel selection for both 2.4 and 5GHz bands, if possible.

But, for the record, your router is old. Really old. You should either call BT and ask for an updated model or simply buy your own replacement (I recommend the latter, as you get what you pay for, and any BT router will be free). If you buy your own, I recommend not spending less than about £50-£60, but a mesh system will likely cost above £150 for much better coverage of your space (and with better reliability than with extenders).

Incidentally, most devices that connect to WiFi are only interested in talking to the internet - it is not fair to compare the connection of one of these with a Sonos system of multiple devices and controllers that are all trying to talk to each other as much as with the internet. The network requirements are different.

I have just deleted half of the posts on this thread without affecting the readability of the thread one iota. For the sanity of the other users involved in this thread, I will soon close it to further discourse. If you have anything further to say, I recommend that you put it all in one post, rather than in 7 or more disjointed ones.

I hope this helps.

This was advised 3 months ago, in multiple posts by multiple members at beginning of this thread.

​The most applicable content in this thread is probably ​@Corry P ‘s signature.

Hi ​@craigski 

I am not saying that it wasn’t already advised, just saying that it needs to be done.

Hi Corry

ill try this thank you. This router is BTs latest one.

i can’t get a newer one. 

The recommendation was to buy one. For the money you’ve invested in Sonos devices, spend a couple of hundred pounds/dollars/Euros and get something decent to match that investment. 

Hi ​@schnawl 

There is simply no way that the Smart Hub 2 is BT’s latest - it was old when I was on the phones for support 6 years ago.

When I was with Virgin and had an old modem that they refused to update with a newer model, I unplugged it, then called them up and told them it simply would not turn on anymore - they soon gave me a newer one.

As stated (and repeated by ​@nik9669a), however, my advice was to buy a replacement. BT hand out thousands of free routers every year - to think they do not do so as cheaply as possible is counter-productive to your mission here.

For what it is worth, I recall having to sometimes disable the UPnP option on BT routers (despite our using UPnP at the time). If I recall correctly that setting is in the Network section of the BT router’s settings. Be aware that we have since moved to mDNS for product discovery, so this may not have the effect it once had.

I hope this helps.

Ok, so it was released in 2018. So Sonos. An American brand has launched products here in the UK which clearly has issues talking to the UKs largest internet provider ..

sorry but I’m struggling to come to terms with this.

who’s at fault here ?

Every other product I’ve ever bought in the 20 + years I’ve been with BT has never had issues. Yet somos somehow, or as someone says on this thread some of somos older products have issues talking to BT.

you guys should be a little clearer here or perhaps launch products with a router thst works alongside them !!!
