401 Authorization Error message

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=desktop

This can be a double router issue.
Please open a Command Prompt on any computer attached to Orbi and type:
> tracert 8.8.8.8 (or traceroute 8.8.8.8 if you're using a Mac computer)
- If you see two private IP addresses listed in the first two hops then you have double NAT. Please check the model of your ISP modem and if you have a manual for it.
- If you see only one private address and the second hop shows a public address, then you’re all good and we need then to troubleshoot further to find the root cause of the issue,
Below is what I get and it appears ok please let me know.
