At One Laptop Per Child we found an issue where the mesh networking wifi packets crashed (actually caused a packet storm) Linksys routers, so just bringing an OLPC laptop somewhere would DoS wifi there. This kind of bug where one device's packets cause another device that it was never tested against to fail is not that uncommon.

Of course, it's funny that a specific game is involved here. Perhaps there are other Switch games that do it too?

When the first-gen iPhone was released, they could break certain wireless networks built on Cisco hardware.
