Preparing Your Network

2-1

This appendix describes how to prepare your network to connect to the Internet through the 
CG814WG Wireless Cable Modem Gateway and how to verify the readiness of broadband 
Internet service from an Internet service provider (ISP).

Computers access the Internet using a protocol called TCP/IP (Transmission Control Protocol/
Internet Protocol). Each computer on your network must have TCP/IP installed and selected as its 
networking protocol. If a Network Interface Card (NIC) is already installed in your PC, then TCP/
IP is probably already installed as well.

Most operating systems include the software components you need for networking with TCP/IP:

•

All Windows

 98 SE or later includes the software components for establishing a TCP/IP 

network. 

In your IP network, each PC and the gateway must be assigned a unique IP addresses. Each PC 
must also have certain other IP configuration information such as a subnet mask (netmask), a 
domain name server (DNS) address, and a default gateway address. In most cases, you should 
install TCP/IP so that the PC obtains its specific network configuration information automatically 
from a DHCP server during bootup. For a detailed explanation of the meaning and purpose of 
these configuration items, refer to 

The CG814WG Gateway is shipped preconfigured as a DHCP server. The gateway assigns the 
following TCP/IP configuration information automatically when the PCs are rebooted:

•

PC or workstation IP addresses—192.168.0.2 through 192.168.0.254

Note: If an ISP technician configured your computer during the installation of a 
broadband modem, or if you configured it using instructions provided by your ISP, you 
may need to copy the current configuration information for use in the configuration of 
your gateway. Write down this information before reconfiguring your computers. Refer
