Question About Sequence of Steps When Replacing a Modem

Is this the proper sequence to install a new modem? I tried installing a Netgear CM600, but the modem never gets to step 5. Should I call Spectrum to provide them with the modem's MAC address before I power up the new modem?

  1. Connect coaxial cable to modem
  2. Connect ethernet cable to modem and a powered down PC
  3. Power up computer.
  4. Power up Modem
  5. Wait for the cable modem to come online
  6. Call Spectrum to have modem provisioned

    Thanks, I got the CM600 modem on-line. Those directions in my first post are from the Netgear manual, and I found that step 5 does not apply with Spectrum. On the Netgear CM600 modem, there is an "internet" indicator light that will be solid green when the modem is online. That light is never going to turn solid green until the modem is activated. For me the correct order was

    Perform steps 1 through 3 as in the first post, then:

    4) Power up the modem

    5) Call Spectrum to have modem provisioned

    6) Wait for the cable modem to come online ( it went online almost instantaneously)

    Thanks for the quick reply on this.

    I still need assistance.

    I do have a Netgear modem active. I want to replace it with a different Netgear modem.

    Are the steps I outlined in my first post correct?

    Thank you for reaching out to us. The steps that you have outlined above are the correct steps. One other thing you can try instead of calling to activate the modem is to try to see if the self activation will work for you. Please go to and go through the steps outlined there.
