Rax54 changes Ip address of devices?
I see my rax54 router to be changing device local IPs multiple times a day. Sometimes i can note the ethernet disconnected notification on my tv as well. Why is it changing IPs so much if i am not ...
ISP Modem/Router is Hitron CODA-4582-U on which I disabled DHCP, it only feeds internet via ethernet into RAX54 which is DHCP server. It has 2.4/5G Wifi networks and 2 ethernet connections (PC+TV). RAX54 Firmware Version V1.0.16.132_2.0.92
Your ISP Modem already has a built in router and wifi. This would be a double NAT (two router) condition which isn't recommended. This would be a double NAT condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAT

Couple of options,
1. Configure the modem for transparent bridge or modem only mode. Then use the NG router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the NG router gets from the modem. https://kb.netgear.com/25891/DMZ-on-NETGEAR-routers

3. Or disable all wifi radios on the modem and connect the NG router to the modem, LAN to LAN configure AP mode on the NG router.
