Re: Comcast blast not getting full speed

I recently purchased a new modem Motorola Surfboard SB6121.  What is the procedure to get it up and running?


Re: Comcast blast not getting full speed

Connect it to the coax cable. Power it up and wait until the "Online" light is steadily lit. Connect a computer to it with an ethernet cable. Open the computer's browser and you may see their "Walled Garden" modem self registration page. If so, follow the screen prompts. Have your CC account number handy.


If not, call 1800-comcast and tell a rep that you would like to have a new modem provisioned for service. Have the MAC address and the serial number of the modem handy. These are typically located on a label on the bottom or the back.
