I have a newer Orbi router with 2 satellites

I'm in a similar position... I have a newer Orbi router with 2 satellites made in the past 2 years and a pair of Sonos One's with a sub. The sub is hardwired but the two One's are in a pair so "Sonos Basement" is all 3 devices. On rare occasion my wireless satellite  in the room with the sub + one's will go out/freeze and usually recover within 5 min or less, but not always. Unplugging the Orbi satellite always resolve as my devices reconnect to the main router or the other satellite. I checked today and saw my Orbi was on auto for 2.4Ghz and my Sonos setup was on Ch 11. I did a wifi scan and saw a neighbor using 2.4Gh Ch 1 so I moved the Orbi 2.4Ghz to Ch 6. Will wait on results but am wondering what your results were after you made your changes?
