play 1 system

@Ian_S yes on Sonos.com in System it shows my speakers. It also shows my speakers on the controller app in System Settings, but not when it searches for them under Manage Network. 
I will try the app reset.

Also I’m using the Sonos controller 80.07.03. Not the S1 controller. If this makes any difference.

Was your system previously working or have you also changed something like WiFi or added new Sonos speakers or reset any speakers? 

Yes previously working on WiFi. SSID and password were changed. That’s when I wasn’t able to connect back to wireless WiFi. Nothing else has changed. I reset the Sonos controller app on my iPad, and no change. Still shows other speakers, but not mine.

If you’ve changed WiFi SSID and/or password then you have to reset the Play:1’s and the playbar… they have no Bluetooth LE to allow the app to connect and change it. See here…

All your products are unfortunately in the unsupported category…

That’s what I figure, but they say you can reconnect them to WiFi with an Ethernet cable. Help desk couldn’t understand why they wouldn’t so they just throw up their hands. I’m going to wait until we change our router before resetting, and if we decide to change WiFi providers I’m sure I’ll have to go through it again. 

Are the Play:1’s surrounds for the play bar?

Two of them are

The surrounds can’t be connected via ethernet to change anything as they use a special bonded wireless connection to the playbar. The only way is a reset and re-add. If plugging in the playbar via ethernet doesn’t allow you to change the WiFi settings then unfortunately it’s a reset too.

The thing to look out for if you have to reset the whole system is whether you have any Sonos playlists. These will be lost I believe, although there are some tools that can extract them. Others here may be able to help more on that. 

If you change router for a new provider, by far the easiest way to do that is to change the new router to have the same SSID/password combination as the old one. Then just reboot everything. Saves a LOT of hassle.
