The recent new app has caused my Sonos system not to link (connect) the the Wifi network created just for it. It keeps connecting to the house network Wifi A that is for other uses.  

I have turned off Wifi A, and auto-connect, in hopes that Sonos would connect to WifI B.

It appears I need to add the Wifi B to the Sonos network in the new app. How do I do that?

Also, I’ve found that my Sonos Move1 will not connect.

Forgive me, I’m not as tech-savvy as I once was, please give detailed 1, 2, 3, type instructions.

Thank you for your assistance.
