Nighthawk CAX30S LAN Configuration
I have a Netgear Nighthawk CAX30S that I am beginning to configure. In the Attached Devices section, I see a wired device that automatically was assigned an IP address of 192.168.1.2 before I even b...
For what it’s worth, I worked out the source of my trouble: an addled brain…. A large part of my confusion is that my tablet and iPod are in fact using two MAC addresses thanks to a privacy feature called Private Wi-Fi Address, which either is turned on by default and went unnoticed by me, or I turned it on when I first got those two devices and then promptly forgot all about that feature. This means the Attached Devices list is correct, and my “need” for adding the “correct devices” as reserved addresses in the DHCP pool to “force” my router to recognize those devices never existed so I deleted them. My LAN configuration is clean now with everything working as it should--with the possible exception of my brain….
You might "forget this" on each apple device, then disable the wifi radios on the apple devices, then power OFF the CAX30 for 30 seconds then back ON. After the CAX30 is bac online, enable the wifi radios, ONE at a time, then reconect one at a time and monitor the IP address seen on the CAX30.
Also be sure to disable any MAC Address randomizers on Apple devices before connecting:
Been months since I had it online so I don't remember off hand. Been testing a CAX80. I run same DHCP pool configuration on the 80.

"STATIC IP ADDRESSES...reside OUTSITE of a host routers default DHCP IP address pool." This is the way my router currently is configured although I did not have it set up this way originally. I adjusted the DHCP pool after the fact, unplugged everything, and restarted the CAX30. I thought that would have reset everything. However as of this writing, the problem persists: two IP addresses for two devices (iPod Touch and iPad) are replicated in the Address Reservation list and in the Attached Devices list.
I asked myself if it is possible those two devices have two WiFi MAC addresses without my previously being aware of this possibility, but I checked both devices more than once and also checked my settings from my previous router's configuration, and I cannot see what I am missing--if anything. Out of curiosity, you stated you have a CAX30. What firmware are you on? Mine is using Firmware Version V1.4.12.2.

Ya, Apple in there infinate wisdom decided to implement that mac randomizer on there devices. Android did the same thing. Causes host names and MAC addresses to be masked by DEV info, meaning some random device. Which when your out side of the home and traveling and connecting to open or unknown wifi sources, keeps the device secure as possible in this environments. However when your at home, I personaly don't think is needed nor do I have these enabled while at home. Any router won't be able to know what the device is, just that it give an IP address to the device as I presume the main intent behind the randomizer. Not needed while at home IMO. So why we meantion disabling it when people post issues with some of these device.
Glad you got it working. Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.

Enjoy. 📡Now that I was made acutely aware of this feature in Apple devices, I don't foresee additional problems and personally appreciate the feature (now that I am aware of it). Eh, live and learn....
Always good to learn.
Enjoy now.
