CM1200 Wifi wont work

Just got my CM1200 and plugged it in, but only the power light shines green. the wifi and others either are off or flash green or yellow.

my isp cannot detect my modem and set it up. please help
  • Yeah, I know its not a router, im talking about the "online light" that wont light up

    I figured out the problem anyway, the coaxial running through my house isnt working

    1. the cm1200 doesn't have wifi. Its a modem only device.

    2. go to netgear.com/support/  type in your model number. it'll take you to the support site with your manual. list exactly what each light is and is doing.

    3. did you hook up the coax to the cm1200?

    4. are you activating over the phone, usine auto-activate, what exactly are you doing?

    5. if you log into the cm1200 (192.168.100.1) what does the connections page show? (take a screen snip)

    6. The cm1200 has 4 ports. the average home consumer can only use 1. port 1 and 2 can be aggregated together but only if your router supports that (most don't). the other ports are useful if your ISP allows multiple public ip addresses (most don't).

        There is NO WIRELESS light. It does not have wireless if you have the CM1200. 

        Look up the manual. It describes the lights. what they are, what each means.
