RBR50 Orbi DHCP assigned some IPs that cannot access to internet
My Config RBR50 restricted DHCP IP range from 21 to 99, but some of the devices auto assigned .1XX and cannot access to internet. This situation appear not only in wifi but also in LAN environment, I...
Your ISP modem/ONT has a built in router already. 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 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=desktopI would try option #2 first, then try #3 if this doesn't change anything.
I would also change the IP address pool size on the RBR to 192.168.1.100 to .200 while the RBR is in router mode.

Please describe what the Orbi shows on the Orbi web interface, Advanced Tab->Setup->LAN Setup. For example, my Orbi shows:
IP Address 192.168.1.1
Subnet Mask 255.255.255.0
This means that any device with an IP address from 192.168.1.2 through 192.168 1.254 should be able to access the internet.
I may have told the Orbi to only assign IP addresses in a part of this space, but ALL of these addresses should work (Many people set aside part of this space for devices that they "assign" IP addresses to.)
So, on one of the devices that cannot reach the internet, what does that device show for its IP configuration? i.e. does it show for the IP address, default gateway, and subnet mask?
