Hi @jmcarpe, welcome to the Sonos Community!
I’m sorry to hear that you’re having issues getting your speakers connected.
Since you have a new Wi-Fi network, and products that don’t support Bluetooth Low Energy (BLE), your options to get them connected are either; Connect them via Ethernet or Factory Reset them. Our community users also suggest changing your Wi-Fi networks SSID and password to match the old one saved in your Sonos products, that way they should just automatically connect.
However, since you’ve Factory Reset your speakers, you’ll have to go with that option and set it up as a new system. If you follow the steps listed in the article, you should get both of your products showing in the app again while also updating your network settings, specifically the steps:
- Factory reset each Sonos product in your system. This will erase all existing system data, including settings, Sonos Playlists, and Sonos Favorites.
- Close and re-open the Sonos app. If all of your products have been reset, the Sonos app will display “No products found.”
- Go to the Settings menu. Your reset products will be detected nearby and show a setup banner at the top of the screen.
- Select one of your reset products and follow the steps in the app to set it up again. You’ll select a WiFi network and provide a WiFi password during this step.
- Repeat step 4 for any remaining products that were reset.
- Add any content services or voice services that were previously on your system.
I hope this helps!
