Orbi frequently shows NOT FOUND 104

[Lesvee]

My Orbi is connected to a Vodafone router (my service provider) and then wirelessly to an RBS50 satellite. I frequently see the message 104 NOT FOUND when looking at web sites using  Orbi network 

However this never occurs when I select the Vodafone network.

I have tried resetting the Orbi numerous times but the problem still persists.

Does anyone know how to resolve this ?

SInce you have a router built in to the ISP modem, 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. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly. Then use the Orbi router in router mode.
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
