Summary

This article provides information on how to connect the Cisco DPC3825 and Netgear CG3000D home gateways with an Ethernet connection.

Solution

Items needed for an Ethernet installation

  • Operating System CD
  • Modem
  • Ethernet Cable
  • Coaxial Cable

    Note: If you are using a hub to connect multiple wired computers, a crossover cable may be required.
Before Proceeding: If you have an existing cable modem, you will need to disconnect it before connecting the home modem.
1

Connect one end of the coaxial cable to the cable wall outlet and connect the other end of the coaxial cable to the modem.

2

Plug the modem power adapter into a wall outlet and the other end into the modem.

Note: Most modems are "on" all the time and do not have a switch. If the modem has a power switch, turn it on and wait forit to synch with the cable network.

3

Connect one end of the Ethernet cable into the back of the modem and the other end into the back of the computer.

4

Check the modem lights for proper status.

Most modem lights operate similarly. Some blink at start-up, then become steady, except for the “activity” light, which may blink continuously. If the modem lights do not come on, turn off the computer, unplug the modem, wait 30 seconds, plug the modem back in, then restart the computer.
