First time purchasing my own router in a long time, vs renting from the cable company.
The C6300 is more than just a "router". It is a modem/router. You would not be the first person to have been sold the wrong device, a modem/router rather than a router. Hence the question about your ISP.
If you do have cable Internet, then you might like to visit the section where people talk about these things.
You might get more help, and find earlier questions and answers specific to your device, in the appropriate section for your hardware. That's probably here:
Cable Modems & Routers
In the meantime you could visit the support pages:
Support | NETGEAR
Feed in your model number and check the documentation for your hardware. Look at the label on the device for the model number.
You may have done this already. I can't tell from your message.
I mention it because Netgear stopped supplying printed manuals and CD versions some years ago and people sometimes miss the downloads.
Don't be intimidated by the manual. The Quick Start guide should be enough.
