> For instance: most people, when their video call stutters, blame their Internet service provider. That’s understandable, since most ISPs are overpriced oligopolists with barely-usable software and horrible customer service. However, every time I can remember helping someone track down the source of their connection problems, the culprit has turned out to be their wifi. Can confirm. I work on videoconferencing infrastructure, and easily 90+% of the end-user quality problems we investigate are caused by the end-user's WiFi. It's very difficult from a customer support perspective too, because it's common for WiFi to have latency and loss problems that are severe for real-time video or audio but not so noticeable for bulk TCP transfers (like most speed tests) or web browsing. So communicating the issue to users is hard.
