Orbi RBK53S Using 4X Data
I recently purchased the Orbi RBD53S-100NAS (Orbi router with two satellites) from Costco. This is connected to the Xfinity router capaple of gig speeds (Model CGM4140COM). I went through the steup...
Your modem has a built in router and wifi. Let us know what mode you have it running in? Bridge or router mode?
Modem Combo Units:
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 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
Has a factory reset and setup from scratch been performed since last FW update? Power OFF The ISP modem for 30 seconds then back on then walk thru the setup wizard after doing a factory reset?
Thanks for the reply. I have the xfinity router in router mode as i sometimes utilize the xfinity network when this one becomes problematic. Prior to using this new orbi setup, they have operated in harmony. Is the double NAT issue only apparent on this model perhaps? Do you think that by putting the xfinity router in bridge mode this will eliminate the excessive data usage? Finally, is there any downside or feathers I'll lose by running the Orbi in AP mode instead of router mode?
To answer your last question, yes, when I did the factory reset I rebooted and also powered down the xfinity router each time as well.
Ok, well you are in a double NAT condition, so anything could be possible here.
I would narrow down where the problem maybe coming from.
If you remove the Orbi from service, does the usage still happen?
Next, I would leave the ISP modem in router mode then configure the Orbi for AP mode. You'll loose featuers on the Orbi accept for Wifi and Guest Network is all.
Run this configuration for a while and check usage to see if this continues.
You might run just the RBR alone with the ISP modem in router mode.
Other alternative would be to bridge the ISP modem and configure the RBR for router mode and test again.
I would also check to see if there are any devices using up data unexpectedly. Turn OFF all devices if possible and run just a one or two.

I would narrow down where the problem maybe coming from. Certainly sounds like the doube NAT could casue excessive data usage, although I'm still not sure I understand why.
If you remove the Orbi from service, does the usage still happen? When the Orbi is removed from service, the excessive usage stops. In fact, i reconnected all of my devices to my xfinity router and things seem to be back in line, so it's definitely something the Orbi is causing.
Next, I would leave the ISP modem in router mode then configure the Orbi for AP mode. You'll loose featuers on the Orbi accept for Wifi and Guest Network is all. If I switch to AP mode, do I lose line of sight as to what is connected to the Orbi?
