EtherFast Cable/DSL Router with 8-Port Switch Chapter 1: Introduction Welcome Thank you for choosing the EtherFast Cable/DSL Router with 8-Port Switch. This Router will allow your computers to share a high-speed Internet connection as well as resources, including files and printers. How does the Router do all of this? By connecting your computers and peripherals to the Router and connecting the Router to your cable or DSL modem, then the Router can direct and control communications for your network.
EtherFast Cable/DSL Router with 8-Port Switch What’s in this Guide? This user guide covers the basic steps for setting up a network with a router. After going through “Chapter 3: Getting to Know the Router,” most users will only need to use the following chapters: • Chapter 4: Connecting the Router This chapter instructs you on how to connect the cable or DSL modem to the Router and connect the PC(s) to the Router.
EtherFast Cable/DSL Router with 8-Port Switch • Appendix D: Windows Help This appendix describes how you can use Windows Help for instructions about networking, such as installing the TCP/IP protocol. • Appendix E: Glossary This appendix gives a brief glossary of terms frequently used in networking. • Appendix F: Specifications This appendix provides the technical specifications for the Router. • Appendix G: Warranty Information This appendix supplies the warranty information for the Router.
EtherFast Cable/DSL Router with 8-Port Switch Chapter 2: Networking Basics An Introduction to LANs Simply put, a router is a network device that connects two networks together. The Router connects your local area network (LAN), or the group of PCs in your home or office, to the Internet. The Router processes and regulates the data that travels between these two networks. The Router’s Network Address Translation (NAT) technology protects your network of PCs so users on the Internet cannot “see” your PCs.
EtherFast Cable/DSL Router with 8-Port Switch A DHCP server can either be a designated PC on the network or another network device, such as the Router. By default, the Router’s Internet Connection Type is Obtain an IP automatically (DHCP). The PC or network device obtaining an IP address is called the DHCP client. DHCP frees you from having to assign IP addresses manually every time a new user is added to your network.
EtherFast Cable/DSL Router with 8-Port Switch Chapter 3: Getting to Know the Router The Back Panel The Router’s ports and the Reset button are located on the back panel of the Router. Figure 3-1: Back Panel Internet This Internet port connects to your cable or DSL modem. 1-8 These eight Ethernet ports connect to network devices, such as PCs, print servers, or additional switches.

EtherFast Cable/DSL Router with 8-Port Switch Chapter 4: Connecting the Router Overview To set up your network, do the following: • Connect the Router to one of your PCs. • If necessary, configure your PCs to obtain an IP address automatically from the Router. (By default, Windows 98, 2000, Millennium, and XP computers are set to obtain an IP address automatically, so unless you have changed the default setting, then you will not need to configure your PCs.
EtherFast Cable/DSL Router with 8-Port Switch Connection Instructions 1. Before you begin, make sure that all of your hardware is powered off, including the Router, PCs, hubs, switches, and cable or DSL modem. 2. Connect one end of an Ethernet network cable to one of the numbered ports on the back of the Router (see Figure 4-2). Connect the other end to an Ethernet port on a network device, e.g., a PC, print server, hub, or switch.
EtherFast Cable/DSL Router with 8-Port Switch Chapter 5: Configuring the PCs Overview The instructions in this chapter will help you configure each of your computers so they will be able to communicate with the Router. Each PC must be set to obtain an IP address (or TCP/IP) address automatically (called DHCP). Computers use IP addresses to communicate with each other across a network or the Internet. Note: These instructions apply only to Windows 98, Millennium, 2000, or XP computers.
