I got up today and found I had no smart device operation. I have about 30 devices. No WiFi, no Internet. I went to login to my router, and it asked me to "Create a password." My router had basically been factory reset. I had to create all my networks and passwords again. All my port forwarding was deleted.

I have been deleting all my smart devices and adding them back, linking them again with Google Home, security cameras, air conditioners, heaters, bulbs, outlets, audio/video equipment, sensors, etc. It has been 3 hours now and I'm not even halfway done. This has been a pain in the ass. I've turned off automatic updates in the router. I hope this will prevent the router from deleting everything.
