NETGEAR NIGHTHAWK CM2000 Quick Start

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.

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
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.
