Upon scrolling through a family friend’s router client list one evening, I noticed something alarming. I was trying to track down connection issues with an unrelated device, and when I had to scroll multiple times to get through the laundry list of devices they had connected, I knew their network was becoming a bit absurd. Most of them weren’t actual devices they used, like a PC, phone, or NAS, but instead, they were IoT devices that were installed and forgotten about: a camera, a doorbell, a TV, some smart plugs, and a handful of sensors. These cheap gadgets typically have the worst track record in terms of firmware security, so I moved all of them to the guest network. It took about ten minutes and solved other networking issues the household was having.
