Connect the Power Adapter to the cable modem.
  1. Plug in the modem Power Adapter to the power port on the Cable Modem and plug the other end of the power adapter into an electrical outlet.

If not, please check the Cable connection. If you believe that the coax cable connections are tightly connected, then please call your Cable Internet Service Provider. It is possible that your Cable Internet service has not been activated.

STEP 4

Connecting the modem to your computer.
  1. Turn off the computer to which you intend to connect the cable modem.
  2. Use the Ethernet cable provided in the package to connect to the 2.5 Gig E port (orange in color) on the rear panel of the CODA56 cable modem and connect the other end to an Ethernet port on your computer.

NOTE: Even though an Internet connection is established, you will need to activate your modem on your Internet service with your Cable Internet provider. See Step 5 below.

STEP 5
