Netgear Orbi CBR40 cable modem won't connect to internet

Hey folks...

Trying to connect a Netgear Orbi CBR40 cable modem.  Went through the process of activating it through XFinity, and it said everything was good to go.  Problem is, it won't connect to the internet.  I know the product says it is not compatible with voice bundled cable signals, but I thought I was fine since we do not subscribe to voice.  But I noticed my Xfinity Gateway is called a voice and data modem.  So I'm wondering if I do have a voice/data bundled signal even though we don't subscribe to voice, and that is why the cable modem won't connect to the internet.  Does that even make sense?  XFinity site says the CBR40 is compatible, so any thoughts on why it won't connect?
