I noticed that anytime I turned on my guest network, my sub and surround speakers that work with my Beam speaker would drop off and it was impossible to reconnect them for more than a couple of seconds. I realized that once I turned off the guest network, they would return online.
Solution. Connecting the Beam to Ethernet causes ALL SONOS speakers to use the SonosNet wifi channel. Previously they were using my default Wifi on the router (with the exception of the three that would drop off, as they were using Beam's SonosNet) Now, after I turn on the guest network on the RT-AX88U Pro, it does not affect the SONOS system and all speakers work as expected. Now, however, All my SONOS speakers show WM: 0 as they are all connected via the SONOS wifi, even speakers in other rooms.
