Are you still using the Sonos S1 app?

Dan,

The first thing I’d try is a simple network refresh, by unplugging the PLAY:5 from power, then rebooting your router. Once the router comes back up, plug the PLAY:5 back in, wire it to the router, and see if it shows up. 

Since you have another Sonos speaker, there is no danger if you want to try a factory reset , but I’m giving those two options about a 30% chance of working. The major concern, which this forum can’t help with, is a potential failure in the wifi system in the speaker. In order to deal with that, your best bet would be to call Sonos Support directly to discuss it.

When you speak directly to the phone folks, there are more options available for them to assist you.

Thanks so much for those followups -- I am using the S2 app, and I have tried rebooting the router and plugging in PLAY:5, without success. Also, I can’t get the factory reset to work on the PLAY:5. I hold down the play/pause button while powering up, but never get anything but white flashing.

My understanding is that it should turn to green eventually. From some other postings, I get the impression that factory reset might not always work with PLAY:5.

The Play:5 (Gen 1) can only be used with the Sonos S1 app.

Sorry for my ignorance! It is actually Gen 2. I didn’t know how to tell, but after researching it, found out that the “smart touch interface” means it’s Gen 2. So it ought to work.
