Disable auto change IP address
I've seen similar posts about a way to disable the auto change IP address before. They've been brushed off. The 'answers' and 'solutions' are wrong. There is an issue with the product. Every month wh...
I have experienced the same problem (among many others) with the Obri. I have AT&T fiber with Arris modem. I'm about ready to ditch Orbi.

Do you have access to your Arris router? Is presume that you already have it in Passthrough mode? There is a setting in the router called "Passthrough DHCP Lease" which specifies how long the host's IP address will be kept private until a WAN address is obtained. Please shorten this time to as short as possible.
Please see page 76 in the manual for Arriss NVG589 as an example here: https://community.arubanetworks.com/aruba/attachments/aruba/unified-wired-wireless-access/26009/1/Motorola%20NVG589%20VDSL2%20Gateway.pdf
- I’ve attached my routers exact info.
It’s in DMZ mode so the orbi’s MAC address is registered in it as a DMZ preset which give the Orbi the public IP. I’m not sure if the setting you mentioned is available for this model as well.- If the ISP router is in DMZ mode then Orbi will always get a private IP address from the ISP router and will never be charged to a public IP address as this post is about.
What issues are you seeing in your Orbi that you think is related to this issue?
Modem Combo Units:
This would be a double NAT condition which isn't recommended. Couple of options,
1. Configure the modem for transparent bridge mode. Then use the Orbi 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 for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode. The Orbi will always get a private IP address on this configuration, since the ISP modem can't be bridge and the DHCP disabled, the Orbi will get a private IP address only.
3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, configure AP mode on the Orbi router. https://kb.netgear.com/31218/How-do-I-configure-my-Orbi-router-to-act-as-an-access-point and https://www.youtube.com/watch?v=H7LOcJ8GdDo&app=desktopI recommend trying option #3...
