You have posted your message in the section of this community given over to Nighthawk WiFi Routers. (This is easily done, given Netgear's impenetrable community structure.)
You might get more help, and find earlier questions and answers about your hardware, in the appropriate section for your device. That's probably here:
Cable Modems & Routers
I will ask the Netgear moderator to move your message.
also, screen snips are easier to read.
I'd also get a snip of the cable connections page.
