Activating WiFi with a Netgear Nighthawk C7000 v.2

I have a Netgear Nighthawk C7000 v.2 already hard wire connected to my Internet service provider, RCN.

Now I also wish to turn on the Nighthawk's WiFi capability--but I'm leery of adversely affecting the hard-wired settings!

Where can I get detailed instructions on setting up the Nighthawk WiFi, so that I can use both WiFi and hard-wired

capabilities?

And any caveats to be aware of when setting up WiFi too?

Thanks in advance for any leads!
