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 router must be assigned 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.

The router is shipped preconfigured as a DHCP server. The router assigns the following TCP/IP configuration information automatically when the computers are rebooted.

TCP/IP Configuration	Current NETGEAR Standard	Previous NETGEAR Standard

Computer or workstation	192.168.1.2 through	192.168.0.2 through
IP Address	192.168.1.254	192.168.0.254

Subnet mask	255.255.255.0	255.255.255.0

Gateway address for router	192.168.1.1 default address	192.168.0.1 default address

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