I had a similar experience to this years ago while working at my mother's kitchen table for while. The network would keep going dead and I had no idea what was causing it.
Eventually, I discovered that it happened every time she used the microwave to heat up a drink or something.
I came to suggest the microwave too. The 24h IP reset sounds more likely, but don't discount the microwave, they typically use the 2.4 GHz frequency (as do bluetooth and some wifi networks of course). So, if the 24h IP reset isn't it, try switching to a 5 GHz wifi network to see if the same dropout occurs. If that solves it, it could be a nearby microwave oven.

Changing to a different WiFi channel fixed it. :)
