when I connect the power, it boots up and after a few moments, appears in the iPhone App. I can then select it, choose music and play. diag 542897432
After a while, the CONNECT appears to reboot, lights flash etc. Sometimes it reappears in the App but most often, the LED lights solid and bright, then disappears from the App or the LED goes out and pressing buttons gives a flashing orange light. diag 85637299
Thanks for sending in the diagnostic report. It doesn't look like there is a hardware issue with the CONNECT. It is normal for a Sonos unit to flash orange when the button is pressed and the queue is clear. The issue may be with your Ubiquiti wifi system. Mesh setups like this are hard for Sonos units to remain connected to. We generally recommend using the Sonos BOOST setup by wiring in at least one Sonos unit (speaker or BOOST), to your main router. This causes the Sonos system to use its own mesh network instead of trying to stay connected on the Ubiquiti mesh. Another option is to check your Ubiquiti settings to make sure the system is not set to automatically switch its wireless channel. If you set the system to a static channel it can help the Sonos system stay connected.
As a test, can you temporarily wire in one of your Sonos units to your main router using an ethernet cable? See if your system's stability increases in this setup.
