Starting points
Turn off and disconnect existing modems and routers.
If you are replacing a modem that is currently connected to 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.
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 it is powered on.
Wait for the Online LED to light solid white
This process might take up to 10 minutes. When the cable modem comes online,
the Online LED stops blinking and lights solid white.
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 that you have service.
Note: When the Online LED lights 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.
Connect a router to your cable modem
- a. Connect the Ethernet 1 port on the cable modem to the WAN or Internet port on the router.
