Orbi

[Canerme]

I purchased a used system at a moving sale . I have yet to be able to register and use this system as it fails every time.

"Fails every time" is not a lot to work with.

What model of Orbi is this?

Have you done a factory reset to clear out any configuration done by the previous owner?

You don't need to register the device to use it. 

It does help with armor/SPC but not for simple setup and usage. 

Where does it fail in the process? 

Have you tried hardwiring in and setting up using a pc/laptop and not the app?
