Install and Activate Your Cable Modem
The cable modem provides a connection between your cable Internet provider’s network
and your computer, router, or WiFi router.
Connect Your Cable Modem to a Computer
After you install the cable modem and activate your Internet service, you can disconnect
the computer and connect a router to the cable modem.
To connect your cable modem directly to a computer:
1.
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.
2. 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.
3. 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 it is powered on.
