I generally always had good results with my regular wifi, but I had more-predictable results with a Bridge (which just produces a dedicated 801.11 "SonosNet" network), when that device still worked for me.
When I occasionally installed Sonos professionally (a long time ago), we always installed a Bridge into a system or made sure that one Sonos endpoint/speaker was plugged into Ethernet by design. In doing so, this allowed the Sonos-widgets to form their own meshed wifi network that generally behaved just fine.
(And no, none of that is quite ideal.
These days I'm mostly divorced from Sonos. But I sometimes have issues with my various Google Home and Alexa devices that connect with wifi. To combat this, I also plug my old-school tiny-ass Chromecast Audio into an Ethernet adapter, as well as the CCwGTV on my main BFT. I do this just to be sure, because having consistent audio is very important to me, and it does work.
But these devices don't make their own mesh like Sonos can do. [Well, maybe Alexa devices can if combined with an Eero router to steer the whole ship, but I don't want that at all.])
