I'm convinced that a wired connection is better for video calls. Just like headphones. I'm my opinion, those two things are table stakes for a good remote work experience for your coworkers.
I was convinced of that until I was forced to stop using a wired connection (moved to a room that didn't have ethernet). I'm on wifi now and notice literally no difference compared to when I was on ethernet. As long as you've got a decent router/AP, modern wifi is really not bad. I get a consistent 400-500 Mb/s up and down with no hiccups. On my wifi 6 devices I get closer to a Gb/s.
It’s not only throughput. Wifi is more susceptible to jitter as well. But yeah in some cases wifi works well, whereas wired always works well. And if wired doesn’t work then your internet connection is bad and wifi won’t help either.
