CM 1200 not connecting to internet

Yes, the wifi router was connected to the CM1200 modem and it was working fine for a few days.
The CM1200 modem stopped working and the "world symbol" light was blinking green. I called the internet provider, they told me they could not communicate with the modem. I called Netgear, they told me it had to do something to do with the "channels", that the CM1200 modem needed to be reset and reconfigured.
Netgear told me that it was something (the resetting and reconfiguration) that I could do from my end, or that if I paid a fee they could do it from their end. I am trying to find the instructions or the way I can do it from my end.
I connected my old modem so I could have internet until the issue with the newer CM1200 modem is resolved.
Please post a copy and paste of the modems connection status page.
Be sure your using a good quality LAN cable between the modem and wifi router. CAT6 is recommended.
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Be sure to power OFF the modem for 1 minute them back ON.
Try a factory reset on the Cm modem. Press the reset button for 10 seconds then release.
