This actually reminded me of an actual instance of this I discovered for a family member.

Their 2.4Ghz devices would just randomly drop connections at seemingly random times, and changing the router didn't fix anything.

So I fired up bettercap to take a look, and lo and behold it was a GE "smart" oven that would spam advertise its SSID with beacon frames on an interval and would block traffic because all the other devices would see a busy channel.

The funniest thing is said family member specifically decided against using the oven wifi feature because he already knew it was not going to be useful or even reliable, but he had no idea the wifi feature was left on which was causing all the packet drops.

Upon further investigation, we realized he actually did turn it off, but because the tap button was basically at elbow height, it was super easy to accidentally bump and flick back on.

Conclusion is that some GE ovens double as a crappy WiFi jammer lmao.
