Latency. WiFi latency can spike which ruins video calls. Simple speed (given lots of time) on the other hand is rarely a problem.

There’s also the problem of sometimes, video calls just stutter and seize up and it’s the internet’s fault, not the local network. But with a wired connection, I am immediately confident the problem is not in my network. With WiFi, who knows, maybe it’s my fault. I used to continuously ping the router so I could verify this, and indeed ping spikes would happen. Now with a wired connection I don’t worry about this.

But yeah if you run no latency-sensitive applications, WiFi might be fine.
