Sonos in a condo w/ interference

If you’re using a BOOST, you’re essentially not using the Orbi mesh. Given you’re in a condo situation, you’re just adding an extra WiFi network (SonosNet) to the mix. I’d ditch the BOOST completely, and hang the Sonos directly off the WiFi signal from the Orbi mesh, assuming it’s set up to not hop channels, and using the most clear channel…and all devices are on the same subnet. And don’t plug an Ethernet cable into a Sonos device, that just resets up SonosNet, again, a parallel network signal. 
 

One thing I’d  do is set up all Sonos devices with a reserved IP address in the Orbi network, assuming it can be done.

Moving off Sonosnet your existing Wi-Fi may be good enough.

The Wi-Fi mode also makes it easier to diagnose connection issues.

I tried to reply. Wait for my next attempt before proceeding.

Before terminating SonosNet I suggest that you Update Networks. Give the system a couple minutes to work through this, then remove all the wired network connections to SONOS devices and power down BOOST. If the system is operational, you are done. You can still revert to SonosNet if necessary.

Do not Factory Reset CONNECT.

If the above fails, it gets messy. You’ll need to struggle through the reset WiFi procedure. Don’t attempt to add any of the PLAY:1’s to your system until all have been Factory Reset. BOOST should be powered down and removed from the system because it is obsolete. It’s probably safer to keep the PLAY:1’s powered down until all have been Factory Reset. Now you can add the PLAY:1’s to your existing system, which is still defined by the CONNECT. (This is why you didn’t Factory Reset CONNECT.)

Ok great, thanks a lot for the replies guys, I appreciate it. I had wondered if, since I was using the SonosNet, replacing my WiFi hardware would even make a difference--makes sense that it wouldn’t.

I’ll give this a try. Annoyingly my Connect no longer has wifi capability, so I’ll have to replace it if the rest of my Sonos products work better off the SonosNet (I bought the Connect refurbished, and something was always wrong w/ its wifi, and even w/ it connected via ethernet cable there were still problems for some reason, so years ago i just opened it up and removed the defective wifi board, which solved that problem at the time).
