I don't know what that means. Did you get a new modem+router, or did
you do something with your old modem+router, or what?
> [...] I cannot find the name of the router on my cell phone, [...]
Do you mean the wireless-network SSID?

C3700[v1] or C3700v2? Look for "Model" on the product label.
Visit http://netgear.com/support , put in your (actual) model number,
and look for Documentation. Get the User Manual (at least). Read.
Look for the LED descriptions and "Troubleshoot". Pay particular
attention to the "WiFi On/Off button with LED". Did you press it?
Further reading might not hurt, either.
