Instant Broadband® Series Chapter 1: Introduction ® The EtherFast Cable/DSL Router with QoS and 8-Port ® The Linksys EtherFast Cable/DSL Router Switch The EtherFast® Cable/DSL Router with QoS and 8-Port Switch is the perfect solution for connecting multiple PCs (up to 253) to a high-speed Broadband Internet connection on an Ethernet network. Configurable as a DHCP server for your network, it acts as the only externally recognized Internet gateway on your local area network (LAN).
Instant Broadband® Series If you use the Router to share your cable or DSL Internet connection, contact your ISP to find out if they have assigned a static IP address to your account. If so, you will need that static IP address when configuring the Router. You can get that information from your ISP. Note: Since the Router is a device that connects two networks, it needs two IP addresses—one for the LAN, and one for the WAN.
Instant Broadband® Series Chapter 2: Getting to Know the EtherFast® Cable/DSL Router with QoS and 8-Port Switch The Router’s Back Panel The Router’s ports (shown in Figure 2-1), where network cables are connected, are located on the Router’s back panel. EtherFast® Cable/DSL Router with QoS and 8-Port Switch The Reset Button The Reset button can be used in one of two ways: 1.
Instant Broadband® Series Full/Col Green. The Full/Col LED also serves two purposes. If this LED is lit up solidly, the connection made through the corresponding port is running in Full Duplex mode. If the LED flickers, the connection is experiencing collisions (when two PCs send data at the same time). Infrequent collisions are normal. If this LED flickers continuously, there may be a problem with your connection. See “Appendix A: Troubleshooting” if you encounter this problem.

Instant Broadband® Series EtherFast® Cable/DSL Router with QoS and 8-Port Switch 17. The Diag LED stays lit continuously. Frequently Asked Questions The Diag LED lights up when the device is first powered up. Meantime, the system will boot up itself and check for proper operation. After finishing the checking procedure, the LED turns off to show that the system is working fine. If the LED remains lit after one minute, the device is not working properly.
Instant Broadband® Series What is Network Address Translation and what is it used for? Network Address Translation (NAT) translates multiple IP addresses on the private LAN to one public address that is sent out to the Internet. This adds a level of security since the address of a PC connected to the private LAN is never transmitted on the Internet. Furthermore, NAT allows the Router to be used with low cost Internet accounts, such as DSL or cable modems, when only one TCP/IP address is provided by the ISP.
Instant Broadband® Series What is DMZ Hosting? Demilitarized Zone (DMZ) allows one IP address (computer) to be exposed to the Internet. Some applications require multiple TCP/IP ports to be open. It is recommended that you set your computer with a static IP if you want to use DMZ Hosting. To get the LAN IP address, see “Appendix F: Finding the MAC Address and IP Address for Your Ethernet Adapter.” If DMZ Hosting is used, does the exposed user share the public IP with the Router? No.
Instant Broadband® Series Browser - A browser is an application program that provides a way to look at and interact with all the information on the World Wide Web or PC. The word “browser” seems to have originated prior to the Web as a generic term for user interfaces that let you browse text files online. Cable Modem - A device that connects a computer to the cable television network, which in turn connects to the Internet. Once connected, cable modem users have a continuous connection to the Internet.
Instant Broadband® Series Dynamic Routing - The ability for a router to forward data via a different route based on the current conditions of the communications circuits. For example, it can adjust for overloaded traffic or failing lines and is much more flexible than static routing, which uses a fixed forwarding path. Ethernet - IEEE standard network protocol that specifies how data is placed on and retrieved from a common transmission medium. Has a transfer rate of 10 Mbps.
Instant Broadband® Series HTML page or send e-mail, the Internet Protocol part of TCP/IP includes your IP address in the message (actually, in each of the packets if more than one is required) and sends it to the IP address that is obtained by looking up the domain name in the Uniform Resource Locator you requested or in the e-mail address you're sending a note to.
Instant Broadband® Series ly used in temporary spaces such as on airplanes, in libraries, at temporary offices, and at meetings. A notebook computer, sometimes called a laptop computer, typically weighs less than five pounds and is three inches or less in thickness. Packet Filtering - Discarding unwanted network traffic based on its originating address or range of addresses or its type (e-mail, file transfer, etc.). Partitioning - To divide a resource or application into smaller pieces.
Instant Broadband® Series Router - Protocol-dependent device that connects subnetworks together. Routers are useful in breaking down a very large network into smaller subnetworks; they introduce longer delays and typically have much lower throughput rates than bridges. Server - Any computer whose function in a network is to provide user access to files, printing, communications, and other services. SMTP (Simple Mail Transfer Protocol) - The standard e-mail protocol on the Internet.
Instant Broadband® Series UDP (User Datagram Protocol) - A method (protocol) used along with the IP (Internet Protocol) to send data in the form of message units (datagram) between network devices over a LAN or WAN. While IP takes care of handling the actual delivery of the data (routing), UDP takes care of keeping track of the individual units of data (called packets) that a message is divided into for efficient delivery over the network.
Instant Broadband® Series EtherFast® Cable/DSL Router with QoS and 8-Port Switch Step One: Pinging an IP Address Step Two: Pinging for a Web Address The first step to determining your ISP’s web and e-mail server address is to ping its IP address. While the IP address returned above would work as your e-mail server address, it may not be permanent. IP addresses change all the time. Web addresses, however, usually don’t.

Crimping Your Own Network Cables Appendix E: Twisted-Pair Cabling • Straight-Through Cabling There are different grades, or “categories,” of twisted-pair cabling. Category 5 is the most reliable and most highly recommended. Straight-through cables are used for connecting computers to a hub.
Instant Broadband® Series Appendix F: Finding the MAC Address and IP Address for Your Ethernet Adapter This appendix describes how to find the MAC address for your Ethernet adapter to do either MAC Filtering or MAC Address Cloning. You can also find the IP address of your computer’s Ethernet adapter. The IP address is used for filtering, forwarding, and DMZ hosting. Find your Windows operating system and follow the steps in this appendix to find the MAC address or IP address for your adapter.
