I have several devices in my home using the Orbi router in both wired and wireless connections. For most of the wired devices – Tivo, AppleTV, Mac desktop – I've switched them to static IP addresses because they kept having IP address conflicts; they work great now. However, sometimes with my wireless devices — iPhones, laptops, iPads — I get an IP address conflict. Usually after a device has left the Wifi network or had wifi switched off; I'll see an error message that says "Another device is using this IP address." I'll then have to wait until the router refreshes the DHCP lease and assigns a new IP address.
Is there something in the settings, possibly under 'Advanced', to force the router to expand the IP address range or else automatically apply a new IP address in case of a conflict? I have 16 devices in the house and only 6-7 are wireless -- there should be plenty of room in the IP allocation to handle everything, so how can I preemptively avoid these conflicts? I'm upgrading from my previous router (Spectrum Arri unit) which is now just the modem, but I never had this many IP address conflicts on the old equipment.
TIA,

That might be your issue right there. The old device not running properly in modem only/bridge mode.
What device specifically is it?
How have you setup the modem only mode?

It's an ARRIS modem, DG1670. I still have the old Wifi network active so that I can go in there and change the settings, but it's definitely in Bridge mode otherwise I would be getting a bunch of rando IP addresses in the wrong range. Unless there's some advanced setting I'm unaware of, just turninig odd the router fucntion/putting it in bridge mode should be sufficient, no?

When modems are in "bridge mode" they definitely do not broadcast WiFi.
Agree with CrimpOn If you have wireless running, its not in bridge mode.
So you'd be in a double nat.

1. Configure the modem for transparent bridge or modem only 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/ExposedHost or IP Pass-Through for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.
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=desktop
