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...

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.

Is the RAXE IP address 10.0.4.42?

The normal MAC ...86:AC is 10.0.4.42. It used to be reserved DHCP release, and now it's static IP.
The new MAC ...86:AD was auto-assigned 10.0.6.21.
(Both 86:AC and :AD are the same RAXE300 device.)

Ok.

The new MAC ...86:AD was auto-assigned 10.0.6.21.By "auto assigned" to you mean assigned by the router using DHCP? Auto-assign normally means automatically assigned w/o a DHCP server, and those addresses would be 169.154.x.x
If DHCP, then I am wondering why it is asking for an address with DHCP when the address is static. Something is odd there.
