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.

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.
