I am trying to add Sonos One Gen2 to my Sonos app. However, every time I try to add it, it fails at the firmware update. It tried a second time, and fails again. It allows me to continue, but the Sonos isn’t added to the Sonos app to manage. 
 

-I’ve rebooted my modem 

-I’ve rebooted the Sonos 

-I’ve rebooted my phone 

-I’ve reset the app

-I’ve factory reset the Sonos one gen 2 

-I’m as close as I can get to the modem, I’ve also tried disabling the 5Ghz antenna

-I’ve signed out and in of the Sonos app

I can’t get the Sonos added to my app no matter what I do. Please help. 

Try connecting the device to your router with a network cable. Also try doing the firmware update with the desktop app if you have a windows or Mac computer. 


Which app? The Sonos Mac OS app only allows me to join an existing system. It doesn’t let me create a new one


I ended up having to set it up via the app. Once the firmware update fails, airplay will still work (even though it won’t be added to the Sonos app). Download the Mac or windows app, and then select connect to existing system. It’ll recognize it, then update the firmware. Then it’ll automatically be added to your Sonos app. This was the only work around I could find.
