CM400 modem will not connect

I have been running this modem for almost two years and today it stopped connecting to the internet. I have called Spectrum and they say that I am getting service. I called Netgear Support to find out after an hour on the phone, that it will cost me $80 to see if they can fix it.

I have power .. I have reset using the little button .. I have disconnected the cable and then reset .. I have restarted my cable box .. the internet light is still off and the stream in and out lights are blinking together continuously.
