I noticed my wifi router had an "update firmware" option. Hmm, I said, that sounds cool. Go to the trouble of looking up the manufacturer's support page for my model, download the file, poke it into the update box, click go. Now all my IOT devices on the 2.4ghz now fall off the network after ten minutes and have to be manually restarted. I'm sure if I spend the time to look into it I'll find some fascinating difference of opinion regarding a detail of the 802.11b spec between the manufacturer of my very cheap wifi router and the manufacturer of the very very cheap wifi radios in my internet-connected thermometer. Instead of doing that, I factory reset the router, and spent fifteen minutes restoring various configuration details from memory.
