Turn off and disconnect existing modems and routers.
If you are replacing a modem that is currently connected in your home, unplug the modem and plug the new cable modem into the same outlet.
Connect a coaxial cable.
Use a coaxial cable to connect the cable port on the cable modem to a cable wall outlet. Make sure that the cable is tightly connected. We recommend that you connect your cable modem directly to a cable wall outlet.
If you must share the connection, use a 3.5dB (1 to 2) splitter.
Connect the power adapter.
Connect the power adapter to the cable modem and plug the power adapter into an electrical outlet.
The cable modem might reset multiple times when you power it on.
Wait for the Online LED to light solid green.
This process might take up to 10 minutes. When the cable modem comes online, the Online LED stops blinking and lights solid green for at least a minute.
After 10 minutes, if the Online LED doesn’t light solid, make sure that the cable outlet is working, or call your Internet service provider (ISP) to make sure you have service.
Note: When the Online LED lights are solid, your cable modem is not connected to the Internet yet. You must connect a router or computer to your cable modem, and then activate your cable modem with your cable Internet provider.
Use an Ethernet cable to connect the LAN port on your cable modem to either a router or a computer. (The computer must have an Ethernet port.)
• Router. Connect the Ethernet cable to the WAN or Internet port on the router, power on the router, and then connect your computer to the router using WiFi or Ethernet.
• Computer. Connect the cable to the Ethernet port on the computer.
Collect the following information:
• Your cable Internet provider (ISP) account information
• Cable modem model number, which is CM700
• Cable modem serial number
• Cable modem MAC address
Activate your Internet service:
The following table lists the activation contact information for cable Internet providers that support your cable modem.

Note to CATV system installer: This reminder is provided to call the CATV systems installer’s attention to Section 820-93 of the National Electrical Code, which provides guidelines for proper grounding and, in particular, specifies that coaxial cable shield shall be connected to the grounding system of the building as close to the point of cable entry as practical.
