Instant Broadband Series Connecting the Cable/DSL Router to Your Network Overview Unlike a hub or a switch, the Cable/DSL Router’s setup consists of more than simply plugging hardware together. Since the Router acts as a DHCP server, you will have to set some values for the Router and also configure your networked PCs to accept the IP addresses that the Router assigns them.
Instant Broadband Series Dynamic IP Addresses Connecting Your Hardware Together and Booting Up A dynamic IP address is automatically assigned to a device on the network, such as PCs and print servers. These IP addresses are called “dynamic” because they are only temporarily assigned to the PC or device. After a certain time period, they expire and may change. 1. Before you begin, make sure that all of your hardware is powered off, including your Router, PCs, hubs, switches, and the cable or DSL modem.

Instant Broadband Series Bridge - A device that interconnects different networks together. Broadband - A data-transmission scheme in which multiple signals share the bandwidth of a medium. This allows the transmission of voice, data and video signals over a single medium. Cable television uses broadband techniques to deliver dozens of channels over one cable. 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.
Instant Broadband Series DHCP supports static addresses for computers containing Web servers that need a permanent IP address. DMZ - (Demilitarized Zone) allows one IP address (or 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 address if you want to use DMZ Hosting.
Instant Broadband Series Full Duplex - The ability of a device or line to transmit data simultaneously in both directions. Gateway – A device that interconnects networks with different, incompatible communications protocols. Half Duplex - Data transmission that can occur in two directions over a single line, but only one direction at a time. Hardware - Hardware is the physical aspect of computers, telecommunications, and other information technology devices.
Instant Broadband Series NetBEUI (NetBIOS Extended User Interface) - The transport layer for NetBIOS. NetBIOS and NetBEUI were originally part of a single protocol suite that was later separated. NetBIOS sessions can be transported over NetBEUI, TCP/IP and SPX/IPX protocols. NetBIOS - The native networking protocol in DOS and Windows networks.
Instant Broadband Series enables the administrator to keep close track of switch performance and alter it if necessary. Port mirroring can be managed locally or remotely. PPPoE (Point to Point Protocol over Ethernet) - A method used mostly by DSL providers for connecting personal computers to a broadband modem for Internet access. It is similar to how a dial-up connection works but at higher speeds and quicker access.
Instant Broadband Series TCP/IP - Transmission Control Protocol/Internet Protocol (TCP/IP) is the basic communication language or protocol of the Internet. It can also be used as a communications protocol in a private network (either an intranet or an extranet). When you are set up with direct access to the Internet, your computer is provided with a copy of the TCP/IP program just as every other computer that you may send messages to or get information from also has a copy of TCP/IP.
Instant Broadband Series Appendix How to Ping Your ISP’s E-mail & Web Addresses Almost all Internet addresses are configured with words and characters, i.e., www.linksys.com, www.yahoo.com, etc. However, these Internet addresses are actually assigned to IP addresses, numerical values which are the true addresses on the Internet. For example, www.linksys.com is actually 206.135.116.3. Type it into your web browser and you will bring up the Linksys home page every time.
Instant Broadband Series EtherFast Cable/DSL Routers Step Two: Pinging for a Web Address Installing the TCP/IP Protocol 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. Because of this, you’re likely to have less problems by configuring your system with web addresses rather than IP addresses.
Instant Broadband Series 6. Find and double-click TCP/IP in the list to the right (below). 7. After a few seconds, the main Network window will appear. The TCP/IP Protocol should now be listed. 8.
