Setting up Orbi satellite system?

[Citykitty21]

Not a tech novice, but...Just purchased the Orbi satellite system R10.  On setup, I am instructed to plug in the Ethernet, then the internet cord into my cable modem, but I don't have a cable modem.  The app kept saying that the cords were not correct.

What am I doing wrong?

What brand and model modem or ONT do you have? Or is there just a Wall jack where you plug in a router? 

R10 isn't a model. Do you have a RBK10 series? 

[Citykitty21]

Orbi RBK10. I have an Ethernet cord coming by from the wall (wire) installed by my provider. No other modem or anything else.

That Ethernet cable coming from the wall goes into the "Internet" jack on the back of the RBR10 router:

Thank you for that clarification.  I will try that!
