RAX120 & EAX80 Subnets
On my RAX120 my IP addresses are coming out as 10.0.0.x and my EAX80 extender is giving 192.x.x.x IP addresses, is that ok or should the extender have the same subnet?
They should be on the same subnet.
what modem/gateway is the RAX connected to? Makes me curious if you have a combo device and the extender is connected to that.
Hey I appreciate the quick reply.. I have AT&T 5000 Fiber on a BGW320-500 (wifi off) connected to my Nighthawk AX12 RAX120 in router mode with the RAX120 running DHCP. Then the EAX80 is connected via wifi to the RAX120. I am running this within a 1,173 sq foot apartment with our own garage about 300 feet from the EAX80 (running a hue bulb, FlightAware server, Waze camera and Meross garage door opener within the garage). I wanted to make sure those items had the best signal so I got the EAX80 but not sure if being in a 3 story apartment complex if all of the wifi signals are killing mine. Issue outside of the subnet issue.
Turning off wifi doesn't disable the att gateway's routing function and still leaves you in a double nat.
A double nat happens when you cascade more than 1 router.

Fixes? There’s 3 options but only use 1.
1. Put the modem/gateway in modem only/pass through mode. This disables its routing functions. Not all gateways function well/properly in this mode.
2. Leave the modem/gateway in router mode but put the Netgears IP address into its DMZ. This forwards the data to the netgear. You can either leave the modem/gateway’s wireless enabled or disabled. Just make sure its using a different wifi channel to prevent interference
3. Put the Netgear into access point mode. This disables its routing functions. Wifi/ethernet still works but it does disable some features.
https://kb.netgear.com/26765/Which-features-are-disabled-on-my-NETGEAR-router-when-it-is-set-to-AP-Mode- I forgot to mention that the AT&T box is running IP passthrough DHCPS-fixed! Would that still be the best? Is the extender getting the subnet from the AT&T box?
- I just did a trace route and found that the first hop was 10.0.0.1 (netgear) and the second was 192.168.1.254 (att box) which would show I have double NAT I believe! I am running IP Passthrough so I am guessing it is not how it should be? Only issues I have been having is my extended is not getting the correct subnet and my Xbox series x cannot update the OS over Ethernet, only works on WiFi! It chokes up when it verifies the software which I guess is a checksum? Also when updating games it will download for a bit then stop then start again then stop!
I'd be betting their passthrough mode not functioning properly.
You could try one of the other options.
Or live with the different subnets if its not causing issues
