Information on connecting to your new ISP modem/router
Good morning, in the area where I live they've installed pure FTTH fiber optics, so my ISP will be changing my router. I have an Orbi RBK 753 system in router mode connected to the LAN port of my cur...

Depends on what the ISP router uses for it's IP address, maybe 192.168.1.1 which is default for most NG router systems, however NG router systems and auto adjust for this.
Your ISP Modem already has a built in router and wifi. This would be a double NAT (two router) 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 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.

Hi, thanks for the reply, I don't care about the double Nat for the use I make of it, that's how it is now too. Sorry, but the image with the Netgear Orbi WAN settings hasn't loaded. It won't let me. Anyway, I'll list all the settings below:
ISP ROUTER IP CLASS: 192.168.1.1. The new router also uses this IP class.
NETGEAR ORBI IP CLASS: 10.0.0.1
ORBI WAN SETTINGS:
WAN SPEED: 1GB/S
WAN AGGREGATION: OFF
CONNECTION REQUIRES LOGIN DETAILS: NO
OBTAIN AN IP ADDRESS DYNAMICALLY FROM ISP: YES
USE THESE DNS SERVERS: I SET GOOGLE'S 8.8.8.8 - 8.8.4.4
USE DEFAULT MAC ADDRESS: YES
These are the WAN settings I currently have on the Netgear Orbi. So when I connect the Netgear orbi with these settings to the new ISP router that has DHCP, the Netgear orbi will get the new WAN IP address from the new ISP router, right? Thanks for the reply.
