Reference Manual for the Model CG814M Wireless Cable Modem Gateway

LAN Configuration Requirements

For the initial connection to the Internet and configuration of your gateway, you will need to connect a computer to the gateway which is set to automatically get its TCP/IP configuration from the gateway via DHCP.

Note: Please refer to Appendix C, "Preparing Your Network" for assistance with DHCP configuration.

Internet Configuration Requirements

Depending on how your ISP set up your Internet account, you will need one or more of these configuration parameters to connect your gateway to the Internet:

•Host and Domain Names

•ISP Domain Name Server (DNS) Addresses

•Fixed or Static IP Address

If you already have cable Internet service and are replacing a cable modem, you may neeed these parameters.

•CG814M Gateway Cable and Device MAC Address, that can be found on the bottom of your gateway, or on the Basic Settings page.

•The MAC Address of the PC that you use to access the internet.

Where Do I Get the Internet Configuration Parameters?

There are several ways you can gather the required Internet connection information.

•Your ISP should have provided you with all the information needed to connect to the Internet. If you cannot locate this information, you can ask your ISP to provide it or you can try one of the options below.

•If you have a computer already connected using the active Internet access account, you can gather the configuration information from that computer.

•For Windows 95/98/ME, open the Network control panel, select the TCP/IP entry for the Ethernet adapter, and click Properties.

•For Windows 2000/XP, open the Local Area Network Connection, select the TCP/IP entry for the Ethernet adapter, and click Properties.

•For Macintosh computers, open the TCP/IP or Network control panel.
