Nighthawk RAX50 not assigning IP addresses to wired devices if switch/NAS combination is present
I have a Nighthawk RAX50 with the latest firmware that has 2 switches attached to it. - Switch 1 has 8 devices behind it (various devices) - Switch 2 has 2 devices (Synology NAS and my laptop) ...
Sooooo... I'm just going to kick myself here. I've been using my MacBook to test everything and sniffing traffic to try to figure out what is going on.
When I put the NAS behind the switch and plugged in the switch, my MacBook was also plugged into that switch so it cut over automatically to using ethernet instead of wifi. My MacBook also had bootpd enabled on ethernet for testing some embedded devices; the script to automatically disable it after testing failed apparently. So when the NAS was plugged into the switch and the switch was plugged into the router, my MacBook was giving all wired devices addresses for a completely different subnet.
When I detached the switch with the NAS to remove it from testing, my Macbook switched to Wifi automatically and bootpd didn't serve anything because it was bound to ethernet only.
It was a combination of testing steps (switch attached or detached) and bootpd not having shut down properly though I swore I checked it. Apparently I didn't swear enough.
Sorry to waste everyone's time. Mods should feel free to remove this since it didn't involve the Netgear router in any way. Otherwise feel free to leave it as a cautionary tale: be careful with bootpd. :-D

what kind of switches are these? managed or unmanaged?
Good question.
Also, another key question, what is the modem/gateway in front of this router?

It is an AT&T Fiber BGW320 using IP passthrough to the Nighthawk

At a quick glance, this describes itself as a "gateway".

To me that says "router". So you have two routers on your network.
I am not familiar with these things. Perhaps IP passthrough takes that into account. If not you may be on "double NAT" country:

The IP Passthrough essentially removes the BGW320 from the network and exposes the Nighthawk to the internet. The Nighthawk is pulling a public IP address and traceroute shows no hops through the BGW320.
