Connecting the Gateway to the Internet

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.

Host and Domain Names:

Some ISPs use a specific host or domain name like

CCA7324-A

or

attbi

. If you haven’t been given host or domain names, you can use the following examples as a

guide:

•

If your main e-mail account with your ISP is

, then use

aaa

as your host name.

Your ISP might call this your account, user, host, computer, or system name.

•

MAC Addresses of CG814M Gateway and PC:

If you have existing cable internet service and are

replacing your cable modem you may need to notify your cable service provider of the MAC

Address (often called Hardware Address) and/or Device Address of your CG814M Gateway. The

Device Address is the equivalent of a PC behind the cable modem, and can be “cloned”. Cloning

allows you to specify the MAC address of the packets the gateway sends to the internet. If you

clone the MAC Address of your PC you will not have to register the Device Address of your

gateway.
