Instant Broadband™ Series face of the Router. For example, if your WAN IP address is 1.2.3.4, you would enter ping 1.2.3.4 and press the Enter key. • If you get a reply, the computer is connected to the Router. • If you do NOT get a reply, try the ping command from a different computer to verify that your original computer is not the cause of the problem. 5. In the command prompt, type ping www.yahoo.com and press the Enter key. • If you get a reply, the computer is connected to the Internet.
Instant Broadband™ Series 6. I need to set up a server behind my Router. To use a server like a web, ftp, or mail server, you need to know the respective port numbers they are using. For example, port 80 (HTTP) is used for web; port 21 (FTP) is used for FTP, and port 25 (SMTP outgoing) and port 110 (POP3 incoming) are used for the mail server. You can get more information by viewing the documentation provided by the server you installed.
Instant Broadband™ Series 8. I can’t get the Internet game, server, or application to work. If you are having difficulties getting any Internet game, server, or application to function properly, consider exposing one PC to the Internet using DeMilitarized Zone (DMZ) hosting. This option is available when an application requires too many ports or when you are not sure which port services to use.
Instant Broadband™ Series 13. The firmware upgrade failed, and/or the Diag LED is flashing. The upgrade could have failed for a number of reasons. Follow these steps to upgrade the firmware and/or make the Diag LED stop flashing: 1. If the firmware upgrade failed, use the TFTP program (it was downloaded along with the firmware). Open the pdf that was downloaded along with the firmware and TFTP program, and follow the pdf ’s instructions. 2.
Instant Broadband™ Series 17. The Diag LED stays lit continuously. • 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 this time, the device is not working properly. Try to re-flash the firmware by assigning a static IP address to the computer, and then upgrade the firmware again.
Instant Broadband™ Series I set up an Unreal Tournament Server, but others on the LAN cannot join. What do I need to do? If you have a dedicated Unreal Tournament server running, you need to create a static IP for each of the LAN computers and forward ports 7777, 7778, 7779, 7780, 7781, and 27900 to the IP address of the server. You can also use a port forwarding range of 7777 ~ 27900. If you want to use the UT Server Admin, forward another port (8080 usually works well but is used for remote admin.
Instant Broadband™ Series EtherFast® Cable/DSL Routers Does the Router replace a modem? Is there a cable or DSL modem in the Router? No, this version of the Router must work in conjunction with a cable or DSL modem. Appendix B: Glossary Which modems are compatible with the Router? The Router is compatible with virtually any cable or DSL modem that supports Ethernet. 100BaseTX - IEEE physical layer specification for 100 Mbps over two pairs of Category 5 UTP or STP wire.
Instant Broadband™ Series 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 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. 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 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.

It enables the administrator to keep close track of switch performance and alter it if necessary. Port mirroring can be managed locally or remotely. control programs such as the operating system and database management system (DBMS). Application software is any program that processes data for the user.
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 C: How to Ping Your ISP’s E-mail & Web Addresses Virtually all Internet addresses are configured with words or characters (e.g., www.linksys.com, www.yahoo.com, etc.) In actuality, however, these Internet addresses are assigned to IP addresses, which are the true addresses on the Internet. For example, www.linksys.com is actually 216.23.162.142. Type it into your web browser and you will wind up at the Linksys home page every time.
Instant Broadband™ Series Step Two: Pinging for a Web 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. Because of this, you’re likely to have fewer problems by configuring your system with web addresses rather than IP addresses. Follow the instructions below to find the web address assigned to the IP address you just pinged. 1. At the DOS command prompt, type ping -a 24.53.
Instant Broadband™ Series 6. Find and double-click TCP/IP in the list to the right (see Figure D-2). EtherFast® Cable/DSL Routers Appendix E: Twisted-Pair Cabling There are different grades, or “categories,” of twisted-pair cabling. Category 5 is the most reliable and most highly recommended.
