Swapping the rental for my own modem

Hi. I bought a Netgear CM500V Cable modem and when I connect it to my computer, it doesn't seem to connect me to the internet. I followed the instructions, but no luck. I reconnect the Comcast/Xfinity modem and the internet is fine. My internet service has already been activated, I'm simply swapping modems. Any clues as to what I may or may not need to do? Trying to get support from Comcast isn't exactly easy.

 

Thanks.

It individually needs to be activated for service. It's MAC address number has to be registered with Comcast.

 

Connect it to the coax line and power it up. Let it fully sync up with the system ("DS, "US", and the "Online" lights are steadily lit). Connect a computer to it and open up a browser. You *may* see their "Walled Garden" modem self registration page. If so, follow the screen prompts. Have your mobile telephone number, your Xfinity username and password or the account number and telephone number associated with your Comcast account handy.

If not, try calling 1-855-652-3446. That is their device activation line.

If that doesn't work for you, you can call 1-800-comcast and tell a rep that you would like to have a new modem provisioned for service. Have the RF / CM / HFC MAC address and the serial number of it handy when you call.
