Preparing Your Network; Preparing Your Computers For Tcp/Ip Networking - NETGEAR CG814W Reference Manual

This appendix describes how to prepare your network to connect to the Internet through the
CG814W Wireless Cable Modem Gateway and how to verify the readiness of broadband Internet
service from an Internet service provider (ISP).
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
to "Obtaining ISP Configuration Information for Windows
"Obtaining ISP Configuration Information for Macintosh
further information.

Preparing Your Computers for TCP/IP Networking

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:
• Windows 95 or later includes the software components for establishing a TCP/IP network.
®
• Windows 3.1 does not include a TCP/IP component. You need to purchase a third-party TCP/
IP application package such as NetManage Chameleon.
• Macintosh Operating System 7 or later includes the software components for establishing a
TCP/IP network.
• All versions of UNIX or Linux include TCP/IP components. Follow the instructions provided
with your operating system or networking software to install TCP/IP on your computer.
