It's been more than two years since I initially reported to #Ring that their cameras poison ARP caches on networks by advertising *themselves* as the default gateway. They have yet to respond in any meaningful way, let alone to fix the issue.
This is horrendous behavior. You don't advertise yourself as the destination for an IP that isn't yours, ESPECIALLY not the network's gateway. It effectively kicks EVERYONE on the LAN off the Internet briefly.
