Hardware Manual for the Model CG814WG Wireless Cable Modem Gateway
2-16 Preparing Your Network
• An IP address and subnet mask
• A gateway IP address, which is the address of the ISP’s router
• One or more domain name server (DNS) IP addresses
• Host name and domain suffix
For example, your account’s full server names may look like this:
mail.xxx.yyy.com
In this example, the domain suffix is
xxx.yyy.com.
If any of these items are dynamically supplied by the ISP, your gateway automatically acquires
them.
If an ISP technician configured your PC during the installation of the broadband modem, or if you
configured it using instructions provided by your ISP, you need to copy the configuration
information from your PC’s Network TCP/IP Properties window or Macintosh TCP/IP Control
Panel before reconfiguring your PC for use with the gateway. These procedures are described next.
Obtaining ISP Configuration Information from Your Computer
As mentioned above, you may need to collect configuration information from your PC so that you
can use this information when you configure the CG814WG Gateway. Following this procedure is
only necessary when your ISP does not dynamically supply the account information.
To get the information you need to configure the gateway for Internet access:
1. On the Windows taskbar, click the Start button, point to Settings, and then click Control Panel.
2. Double-click the Network icon.
The Network window opens, which displays a list of installed components.
3. Select TCP/IP, and then click Properties.
The TCP/IP Properties dialog box opens.
4. Select the IP Address tab.
If an IP address and subnet mask are shown, write down the information. If an address is
present, your account uses a fixed (static) IP address. If no address is present, your account
uses a dynamically-assigned IP address. Click “Obtain an IP address automatically”.
5. Select the Gateway tab.
