IP Assignment Issues -- tied to SSID in some odd way? At a loss.. (RBR750)

What Firmware version is currently loaded? V4.6.5.14_2.0.54

FW same version on RBS as whats loaded on the RBR? Yes

What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too? Netgear CM700

Has a power off for 1 minute then back ON with the ISP modem and Orbi system been performed since last update? I changed the name of the SSID and went through my home and reconnected all of the devices. TBH, I'm terrified to power cycle the system as I've spent 10+ hours diagnosing and reconnecting everything over the last day of so. The sequence mentioned in your post is the sequence I utilized to attempt to have devices reconnect/get an IP address and it failed. I repeated this process at least 5 times before moving on to other actions.

What is the size of your home? Sq Ft? 4500 sqft
What is the distance between the router and 📡 satellite(s)? RBR to RBS1 is roughly 30 ft (RBS1 is outdoors on covered patio). RBR to RBS2 is likely closer to 60-70ft. RBS2 is on a floor above RBR, and on the opposite side of the house. 

What channels are you using? 2.4ghz is set to Auto and 5ghz is set to 48. I have never changed these.

Any Wifi Neighbors near by? If so, how many? Sitting at the front of the house, I can see at least 3 other networks. I would say there are at least 5 detectable networks depending on where I'm at in the house. 

Try disabling Armor: I will try, but this issue existed on my RBR50 previously and that did not have the Armor service. I'm not sure this will do anything.
