Connect Amp - how many models

This was apparently a 2007 vintage device.
Does it have a mark on the right side? It could be my old one.... Just kidding.

Whatever, it's good that you have it up and running. It doesn't have the processor/memory capabilities of the Connect:Amp, so it's not quite the same in terms of functionality. For example it can no longer do an incremental library index scan, but that may not be important to you. So far, the ZP100 -- and its approximate contemporary the ZP80 -- have managed to retain the important functionality in terms of actually playing music.

No mark on the side that I can tell, ha! But now what I'm experiencing is that it disconnect and disappears from my system after playing music for a period of time. I have to unplug it and replug it in, or I have to re-setup. Has anyone had to do this before?

How long does it take before it disappears? If you don't actually play any music does it remain visible in your Sonos controller?

Next time it disappears submit a diagnostic if you have any other Sonos devices to do that from.

Amy odd light blinking / colors from the status light? https://support.sonos.com/s/article/226?language=en_US

Have you tried connecting it to Ethernet to see if the problem is with the WiFi connection?

Hi! When it stops playing, it does appear to continue playing on my controllers even though you cannot hear it and my Alexa echo dots thinks that room is still playing too. No strange blinking lights. And yes, tried direct internet tie in.

The amount of time varies but usually just under one minute. Sometimes it stays visible in the controller but the controller and all other controllers such as Alexa thinks it’s still playing. Other times it disappears from the controller entirely.

Maybe a faulty power cord? It is pushed right in? As suggested a diagnostic is best bet from here.

When music is playing, a controller doesn't stay in continuous contact with a player. The player can quietly expire, yet the controller will continue to show it playing ... at least for a time.

I was curious to know whether it was the actual playing of the music which was upsetting the ZP, in which case I would suspect a hardware fault. Increased temperature could be causing an aged component to go out of spec.

If the ZP drops off the network even when left idle it might suggest a network issue, such as a simple IP conflict which a full network restart should resolve. An IP issue would usually cause a player to come and go though. If, after a while, it just vanishes I fear it could again be hardware related.

To be perfectly frank, given that this was advertised as a Connect:Amp at this point I'd be reaching for the 'Item not as described' button on eBay and looking for a refund.

There is a ZP100 failure mode that will result in similar symptoms and I've seen this cause other network issues.

As a quick diagnosic and possible workaround, wire the unit to your network. If there is wireless interference or a defective ZP100 radio, the wired connection will get you going.

Note that there is another ZP100 failure mode that disconnects the network ports from other parts of the player.

My ZP100's are still working and are from the original production run.

Wireless interference leaves clear tracks in the diagnostics.
