Hope it helps you to resolve the matter.👍

Thank you, I reinstalled the app as instructed at one point now it will not open.  Do I redo all that?

You don’t need to reinstall the Sonos App - it can be simply ‘reset’ if the Household has been completely wiped-out by factory resetting all products in one fell swoop - that’s certainly not recommended. So don’t do that.

I’d just wire one non factory-reset Sonos product to your router and then reboot the other players and when all are showing in the App, go onto remove/replace the old WiFi credentials with the new ones, as instructed.

Note, it’s best to use a more modern Sonos product with .BLE built-in to add the new WiFi credentials to it these days, as the process is really simple using that connection method. 

If you get stuck, rather than factory resetting any of your devices, it might be easier and perhaps save you time, if you let Sonos Support walk you through the steps. The link to call them is here:

By the way another simple option is to change the new router SSID/Password to match your old router - then everything should just connect.

I think calling is the best option, I used old router pw and then new one and it won’t take either. 

I have done it all and reinstalled the app on my phone we were doing good then when I enter the router password it rejects it.  I used the old ATT password from the old router, nothing workes.  The router company gave me the password and it does’t work.  

I just need to put them out on market place and get another brand.

Perhaps a silly question, but did you change the SSID in the Sonos network settings? The old SSID will not work with your new router, no matter what password you use. Did you not get in touch with Sonos Support, like you mentioned earlier?

I was going to call tomorrow but tried again tonight.  How did I change the SSID I didn’t see where I could do this?

Fixed it, don’t know what I did but it works.  wow…..   YEA
