I may have found it... should have waited to post. Despite turning off automatic updates on the new user interface, I had to go to the old interface, Services > Scheduled Upgrades and disable it there too.

What is UI doing? lol

@JaredBusch I don't know. I do not remember turning it on. However, I've been all through these settings repeatedly over the last week+ and it's possible I or one of the other techs configured it. We've lost a lot of time to this DHCP issue.

The fact that I have lost 2 months over this issue, and it's still happening, is absolutely absurd.

The absurd thing is that you have not simply rolled back the firmware to the prior working version.

You obviously aren't following along. I've rolled back to the supposedly working firmware and it still does it.

Having this issue at multiple sites that were all set up within the last year. It wasn't as obvious at the other sites because the people don't leave with their laptops for days.

@CCWTech did it end up being unrelated?

I think so. Everything seems to be stable on the RC version. We have switched clients to the RC and they are not having issues any longer.

Our DHCP lease time is 3 days at the office that is affected.

A staff member was in the office all day Monday with their laptop. On Tuesday and Wednesday, they worked in different offices (with EnGenius WAPs using a different SSID/password.) This morning, she came back to the affected office and she couldn't get an IP address. Same DHCP problem. Unifi Controller shows the DHCP Timeout/Failure.

All of the WAPs are on 4.3.26.11358. The controller is atag_6.0.43_14348. We are using Ubiquiti EdgeMax switches (not Unifi Switches) because I need more control over our entire network. We are using a SonicWall TZ-500 router.

I have literally hundreds of locations with Unifi switches and SonicWall TZ routers. I have never, and will never, use their router in a business. The fact that I have lost 2 months over this issue, and it's still happening, is absolutely absurd.

This is supposed to fix the issue: https://community.ui.com/releases/UAP-Firmware-4-3-26-11358/e05cd041-ea54-460c-85f4-7f3fd97261e8?page=8

I just installed this today. Thanks.

I had previously rolled back the firmware, but that didn't permanently fix the issue. It was still happening.

Hoping that this new firmware fixes it.

After downgrading to 4.3.20 and disabling automatic updates, I woke up and 4.3.24.11355 was reinstalled. What am I missing here? Is there another setting that I have to clear the old firmware from or it will automatically load it overnight?
