Wireless Broadband (Switch) Router Standard/Pro/Advanced/Advanced+ User's Guide Version: 2.10 Last Updated: 01/17/2003 Federal Communication Commission Interference Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiated radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures: Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. FCC Caution: To assure continued compliance, (example ­ use only shielded interface cables when connecting to computer or peripheral devices). Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. FCC Radiation Exposure Statement This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20 cm between the radiator & your body. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. i R&TTE Compliance Statement This equipment complies with all the requirements of DIRECTIVE 1999/5/CE OF THE EUROPEAN PARLIAMENT AND THE COUNCIL OF 9 March 1999 on radio equipment and telecommunication terminal equipment and the mutual recognition of their conformity (R&TTE).

Introduction 1.1. Overview The wireless broadband (switch) router enables IEEE 802.11b and Ethernet client computers to share an Internet connection provided by an Internet service provider (ISP). The Internet connection can be DSL, cable, V.90, or ISDN-based. In addition, it also serves as a wireless access point, so that the wireless client computers and the Ethernet client computers can reach one another. There are 4 different model variations, Standard, Pro, Advanced, and Advanced+, which are classified in terms of features. The Standard edition provides the fewest features while the Advanced+ edition provides the most. With the sleek Web-based user interface and Windows-based user interface (Wireless Network Manager), a network administrator can easily and clearly manage the wireless broadband (switch) router. Since the wireless broadband (switch) router provides rich TCP/IP and WLAN (Wireless Local Area Network) functionality, a basic understanding of the inner workings of TCP/IP and IEEE 802.11b is necessary. Essential TCP/IP concepts include IP addressing, IP routing, IP name resolution, DHCP (Dynamic Host Configuration Protocol), and PPP (Point-to-Point Protocol). Essential IEEE 802.11b concepts include channel numbers and WEP (Wired Equivalent Privacy). In Chapter 2, we describe the steps to install and configure a newly acquired wireless broadband (switch) router. Following the steps, the wireless broadband (switch) router can be quickly set up to work. In Chapter 3, detailed explanations of each Web management page are given for the user to understand how to fine-tune the settings of a wireless broadband router to meet his or her specific needs. In the remainder of this guide, a wireless broadband (switch) router is often referred to as a WIASA (Wireless Internet Access Server Appliance) for short. 1.2. Features Configuration Reset. Resetting the configuration settings to factory-set values. IEEE 802.11b Access point. Bridging packets between the wireless IEEE 802.11b network interface and the wired Ethernet LAN interface. 64-bit and 128-bit WEP (Wired Equivalent Privacy). For authentication and data encryption. Enabling/disabling SSID broadcasts. The administrator can enable or disable the SSID broadcasts functionality for security reasons. When the SSID broadcasts functionality is disabled, a client computer cannot connect to the wireless router with an "any" network name (SSID, Service Set ID); the correct SSID has to be specified on client computers. MAC-address-based access control. Blocking unauthorized wireless client compute ...
