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.

Track the symptoms.

Do you lose Wi-Fi completely? Only? Can weird devices connect?

Can you communicate with anything on your network?

Can you ping your gateway? Your external IP address?

Can you determine when your IP leases expired?

What if you reset just your ISP hardware? Just your hardware?

Connection from router to isp is lost. I only reset my router, not the modem.

How do I see when ip leases expire ? Either from linux or the unifi gui..

I'm not familiar with the unifi interface, but hopefully it should provide that information.

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.

it might just be shitty hardware, my router is a $20 cheapass from china and did this pretty often. replacing the adapter that came with it seems to have solved it for now.

My household has the router scheduled to reboot at a time when everybody's asleep once a week.

I had a cable isp issued modem that did the same thing, except it was closer to every other week. I replaced the modem with a nice arris surfboard. Fixed the problem for me on Spectrum for the last two years. Only needed to reboot once every 6mo or so.

Lately though, they've been upgrading the network in my area (gigabit bidirectional cable, yay) but the service has sucked on and off for the past two months. I'll have bad days where my internet is struggling to hit 20mbps down. Rebooting my hardware rarely helps.

I jave an artist surfboard also,

Yeah. Must just need reboots sometimes. I think it had been 2 months. I cant complain!

Most of the time I've seen this, it's usually just shitty cinsumer grade firmware full of memory leaks.
