RAXE300 serving DHCP despite AP mode
tl;dr: I have the RAXE300 in AP mode, but it's suddenly serving DHCP.
I've had a Netgear Nighthawk RAXE300 (6E) since August 2024, and I always used it in access point mode. My LAN is 10.0.x.x with DHCP server on OpenWRT router (which has no Wi-Fi). A few days ago, I suddenly started getting Wi-Fi outages, which were temporarily resolved by rebooting the Nighthawk. However, the Netgear DHCP server is providing 192.168.1.x addresses
tcpdump -i br-lan -n -e 'udp port 67'

Not seeing 192.168.1.x in your TCPDump.
Finding anything else if you disconnect the RAXE from the system temporarily?
Is the RS router in AP mode actually? Check the WEB UI.
Try setting a static AP mode configuration as seen here on the RS Router:
Be sure that the static IP address is not inside the host routers default DHCP IP Address pool range.
