I work from home, in a home office with no sane way to route an Ethernet cable to, and I've been feeling the crunch during video calls. We have a wifi-enabled baby video monitor in a corner bedroom, and from my experience it's been proving "Rule 10: Your Wi-Fi network is only as fast as its slowest connected device" (see source [1]). My best-practice workflow has been to unplug the camera before an important video call.
