It seems to happen maybe once a month or every 2 months. Sometimes random. Is it my ISP renewing my IP? How can I check that?

Im on all unifi hardware. Not a total noob but I struggle with the concepts.

I have a UniFi EdgeRouter (old, and I'm looking into replacing it with a FreeBSD box) and I have a similar issue where the router -- but maybe the ISP? -- misses a DHCP renewal, resulting in the wholesale loss of connectivity. It's even more annoying because the ISP simultaneously rejects follow-up DHCP requests, on the theory that if the renewal was missed, the device cannot possibly exist anymore, at least for a few minutes.

Since this router takes 12 minutes to manually reboot, that's usually enough time for the ISP to clear their cache and everything comes back up properly. But it's terribly annoying, hence why I'm looking to finally replace this router.
