IP assignment issue? Devices not connecting

 Hi All,

Last night I lost power to my orbi, upon restart, only 50% of my devices reconnected. I have ~65 devices between TP Link switches, phones, Alexa devices, and laptops. I thought it was potentially a TP Link issue, but my new Samsung Galaxy S20 was also alerting me that "couldn't get ip address." I assume this is the issue w/ the smart devices as well. I went ahead and updated firmware to 2.6.1.40 and still no luck - in fact, less devices have connected (17). I'm at a loss -- I've done a factory reset, turned off/on the "Use Router as a DHCP server" setting, flipped my security TKIP+AES and then back to AES. Nothing. Help!

Modem: Netgear CM700

Router: RBR50

Satellite: RBS50
