Wired ethernet resolves most of my own teams/zoom/webex etc anxiety that any glitches in anyones meeting video or audio are probably NOT caused by my own connection....
At home, my WiFi vs Ethernet ping is just a few ms different. For data, my WiFi 6 devices (most of them now) are faster over WiFi.
But, at work, there's hundreds of ms difference between ethernet and WiFi. I assume it because most offices use mesh networks now, and none here are WiFi 6.
So, network setup and router quality definitely play a part. My AP was ~$200, used for streaming VR.
The LATENCY is noticeably better. If you are on a zoom call with both parties on headsets and on wired connections (so no echo cancellation needed) or other audio connections I find it noticeably better (less stepping on each other etc).
I have AT&T's fiber product (2 Gbps) and the office has their biz product (300 Mbps) and latency between is good and to google et al is great (< 10 ms in almost all situations).
