Bluetooth on Roam

I’m so sorry but if I don’t find an efective Sollution to these issues, I’ll be returning it soon. 
Great speaker, anyways 

The Roam, like other Sonos speakers, is stable and reliable.  If you are having problems when it is on your network, then the issue is a networking one - drops in sound are due to network issues 99.9% of the time.  This does not mean that there is anything faulty about your network. if may be that a setting needs changing somewhere, or that there is wireless interference. Or maybe just that you are too far from the router.

Tell us more about your router and network.  Is it a mesh? Any extenders or access points?  Dual band?

You have to resolve this.  There is nothing for Sonos to resolve.  My Roam, like Bruce’s, operates without a hitch.

Thanks for your reply  John, I appreciate it.  Reliable? Stable? Mmmh! 
Well I have a modem, the Router and a Wifi repeater, and two networks with different names, but in my main network it often has connectivity issues, so I need to change it to an other network. Even though, Alexa gets stuck, Airplay cutting out, Apple Music stopped and skipped the last week or so, etc. 
The walls in my home are made of concrete and clearly this can interfere with the signal, but here my concern is:  none of my other devices are having  an issue, neither my iPhone 11, neither my iPad Pro, neither my HP laptop, neither my Alexa 4th gen,   neither my brother’s  Xbox Series X and neither  the rest of all other Devices in my network, just the Roam. Why? I’m glad I’m not the only one, but looking at other posts here in the community, many people don’t seem to fine an effective solution to these issues. What is the main cause?    What should I do if one of  my  neighbor installed a new device that’s causing interference in my environment? Talk to him and explaining that I have issues with my network? Let’s fix it. 
Thanks a lot for your kind help 

Why is the Roam the only problem?. Possibly because it is only one that has to talk to another device or devices across your network.

You have two networks, one with an extender. Extenders are not supported by Sonos. You can get away with a poorly configured network with lots of devices, but not Sonos. And your network situation sounds a bit of a mess. 

But you have clearly made up your mind that it is the Sonos that's the problem, so I wish you well

Well John, I’m not  criticizing Sonos in any way, be aware that I’m just trying to find a solution to these issues, trying to stop my roam from behaving unstable, as technical support in Mexico is so unresponsive. 
I absolutely love my Roam as a sounding speaker, sounds great being too small, I tested outdoors near the beach and it was amazing. I just want to stop it from being so unstable, Which network requirements does it need to work flawlessly and errors free? Reading many posts here in the community, it seems to be a común issue without any fix, and this is the only and the first Sonos speaker I’ve ever had, so, if I don’t find any efective sollution to this issue, I’ll probably be returning it soon       

Have you yet gone onto try the suggestions provided to you earlier, in the various other threads - for example: Shift the Roam off your 5Ghz WiFi band onto the 2.4Ghz band and select a channel-width of 20Mhz?

I'd be happy to see if I can help make your Roam stable. Shall we try?

First question has to be why do you have two networks?

Do both routers have 2.4 and 5GHz bands? Do the bands have separate SSIDs.

Does the extender have the same SSID and password as one of the routers?

I’ll try firstly to set my wireless channel into my main  router hoping it would solve the matter, anyways, it’s been stable with Bluetooth playing content from YouTube, no audio  drop outs at all so far after a large reboot of my router an reinstalling the Sonos app   

Answering your questions, my main network seems to be 2.4 gigahertz because we had the 5 gigahertz but it  was removed, it no longer appears in the list,  but my Roam is connected to the second network because it seems more reliable for it to work because I noticed it was having many issues with the main one, I don’t know why, is the strongest.

We have two networks because my house is too big, in the back we have a new building for guests, where we have a dining room/ kichen downstairs, and upstairs a music livingroom, 2 bethrooms and a bathroom, and there isn’t enough signal for the main router so we had to put a repeater, and yes, they have different names and different passwords, and I don’t know anything about the SSIDs, neither  the channel of my main network, but the Tech support noticed in a diagnostic that my Roam was using the channel 48 and 2.4 gigahertz, but I don’t know if my provided network has the ability to change the channels into either 1 6 or 11 which are the ones that Sonos recommends for minor wireless interference. 
Thanks for your kind help guys      
 
 

SSID is the WiFi name. Channel 48 is in the 5GHz band. Channels 1, 6 and 11 are in the 2.4GHz band.

Please give model numbers for the router and the repeater.
