Changing wifi signal on sonos roam

Hi @Erniebilko 

Welcome to the Sonos Community!

First, please ensure that your phone/tablet is connected to the extender’s WiFi.

Then, 

1. Open the Sonos S2 app for iOS or Android.
2. From the Settings tab, press System > Network > Manage Networks.
3. Press Update Networks and follow the prompts to connect Sonos to your extender’s Wi-Fi network.

Please note, however, that WiFi extenders are not supported and you may not see the Roam in the Sonos app when your phone/tablet is not connected to the extender too. You also may not be able to see the rest of your Sonos system in the app when your phone/tablet is connected to the extender. It may also work without issue, though - fingers crossed! This may or may not match with your requirement of an “independent speaker network”, but I’m not entirely sure I understand what you mean by that. The Roam can and will play independently of other speakers whether is setup as a different system or not. For it to play together with other speakers, they have to be part of the same system. I recommend you keep them as one system, even if you intend to use them separately, as having two Sonos systems of the same version (S1/S2) on one network introduces more complications.

I hope this helps.
