connecting sub mini and surrounds to Beam (gen 2)

Do you have any VPN,  blocking or filtering enabled on your network? Try disabling it.

If that doesn’t work power down all Sonos, reboot router and controller, wait a minute and power up just the Beam, see if it is working as expected. If so check for updates and apply any pending.

Power up the 100s next, check and do updates if any.

Last do the Sub as above.

If that doesn’t work tell us more about your network and someone may have an idea.

Another option is to submit a diagnostic (power everything on and give it 5 minutes first) then CALL Sonos support. Other contact methods might work too but calling seems the best option.

The ‘most of the time’ comment suggests that ​@Stanley_4 ‘s second suggestion might be more helpful. 

Thanks Stanley - No VPN or blockers. I’m no tech wizard, but I can’t see anything there. All updates duly installed.

I’ve managed to connect the two Eras to the Beam, but no luck with MiniSub. 

It often takes a while to register - ie. switching on the app, it takes a few minutes to actually register that there is a Sonos system attached to the wifi. Sometimes then it decides one doesn’t exist and can’t connect. Which is frustrating.

Thanks for your help here - I’ve spent over two hours on the phone to sonos, and no results as yet, but your advice got me further!

Can you describe your network?

Is your ISPs device the only router or do you have a mesh network installed?

Are you able to wire the Beam to your router with an Ethernet cable?

Opening the app your system should connect within a few seconds. It sounds like there may be WIFI interference.

Thanks Pools.

What do you mean describe the network?

ISP is vodafone wifi hub (model THG 3000). Seems to be all on 2.4 ghz. I’ve switched off Private wifi address.

I use Tapo smart switches / lights / plugs etc. They use the wifi. WOuld that interfere?

We do have an extender, but was off all of yesterday and seems to have made no difference. I switched it on this morning, and started to work fine for about an hour (sonos was connected to hub, and my phone connected to extender).

Now Sonos isn’t working again - music playing on the beam and two Eras, but app can’t connect (shows “No Content”), but there clearly is music playing. It sometimes shows “No products found on Wifi network”. When music is clearly playing… Doesn’t matter if my phone app is connected to hub or extender. 

I don’t have an ethernet cable - I can buy one, will this help the set up process? I’d rather not have ethernet cables throughout the whole floor!

Here is what Sonos recommends and does not recommend to be used within your network. Extenders are one of the devices that are not recommended:

There are times when Wi-Fi interference causes connection issues, and some users find it helpful to hardwire at lease a single speaker to the network. In your case, I suggest trying hardwiring the Beam, leaving it WI-FI enabled in settings. Surrounds and Subs bond to a private WI-FI transmitted by soundbars and the Amp, so a solid connection to your network first will help.

If this configuration solves your issues, you may want to find a way to make it permanent.

If being totally wireless is more important, you will have to find the source of the interference.
