C-4 Preparing Your Network

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 computer, 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.

In your IP network, each computer and the firewall must be assigned a unique IP addresses. Each

computer 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 computer 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 “Appendix B, “Network, Routing,

Firewall, and Basics.”

The WGX102 Wall-Plugged Range Extender is shipped preconfigured as a DHCP server. The

WGX102 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

• Subnet mask—255.255.255.0

• Gateway address (the firewall)—192.168.0.101

These addresses are part of the IETF-designated private address range for use in private networks.
