My setup is as follows:
TV surround setup (Playbar, Sub, 2x Play:1 surround)
Main living area and kitchen (2x Play:5)
Connection: 1x Bridge on one end of condo and wired connection to the Playbar at the other end; balance is confirmed Sonosnet
2x Ubiquiti UAP-AC-Lite Access Dual Band
USG Security Gateway
24MBPS cable internet
MOCA bridge to APs / Playbar
I have tried:
Resetting the controller
Rebuilding the Sonos installation (Factory re-sets and clean install of controller)
Stipulating Sonosnet channel
One other odd behavior is that on my last visit my playbar had dropped from Sonos installation (no longer visible to controller) and, would not re-connect until I made the wired connection.
I suspect I have some sort of signal issue either from a failing radio/antenna in the playbar or, more likely an interference issue. To attempt to address the interference issue I replaced my Ubiquiti access points with newer dual radio units and made as much of my other wifi stuff as I could use the 5ghz band - no improvement.
Looking for any troubleshooting ideas this group may have!

Also if this is a location you don't visit regularly, are shutting off the power when you're not there? This might explain why the playbar dropped off, if the router gave it a duplicate IP address.
And condos are likely to have a lot of wifi networks around. it could be interference from a neighbor's network.
