DHCP Address Reservations not Working

It's actually set to 192.168.1.1...

But it didn't work anyway.

I did what you said: reset the router, reinstalled the firmware on both the router and the satelite. I even factory reset the unicorn for funzies.

I had my MAC addresses written down ahead of time, created the reservations and then started plugging devices in. One-by-one they received the wrong IPs. I turned DHCP off on the Orbi, created a scope on my Win 2016 Datacenter Server, set my reservations and activated it and long behold, every device received their reservation almost instantly...

I plugged in the back haul on the satelite, cause you seemed surprised that I reported that it didn't work. I got about 5 feet away when I got an alert that my internet was down, and (surprise) the Orbi was offline. No lights, couldn't PING it, couldn't get to the config page. Just, down... I went back, turned off the satelite and router came back up about 30 seconds later. I plugged the satelite back in, and it went back down...

I factory reset everything, isolated just the router, satelite and my laptop (no unicorn or other devices). Did not set any options, left everything default, then plugged a CAT6 cable into the router and the satelite... And it went down, almost instantly (had a PING -T going). There's obviously still an issue with the Ethernet Back Haul that Netgear is not reporting, or I have a defective unit (and support is usless, I've been on hold for 2 hours now waiting for someone).

At this point, I'm over it. I'm going to find a new system and send this one back to the depths from which it came (most likely with a 20 lbs sledge).

Unless someone has another suggestion other than blaming it on another piece of equipment I have (which everything else is working just fine).
