SI5WUB321ASuper G USB 2.0 WLAN Adapter With Smart Antenna

Super G USB 2.0 WLAN Adapter with Smart Antenna User's Guide Version 0.8 2 FCC Warning 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 radiate 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 or more 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. 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. (2) This device must accept any interference received, including interference that may cause undesired operation. 1. This Transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. 2. This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20 centimeters between the radiator and your body. 3. Any changes or modifications (including the antennas) made to this device that are not expressly approved by the manufacturer may void the user’s authority to operate the equipment. U-MEDIA declares that WUB-321A, ( FCC ID: SI5WUB321A ) is limited in CH1~ CH11 for 2.4 GHz by specified firmware controlled in U.S.A. 3 CE Mark Warning This is a Class B product. In a domestic environment, this product may cause radio interference, in which case the user may be required to take adequate measures. This transmitter must not be co-located or operation in conjunction with any other antenna or transmitter. 4 Table of Contents Federal Communications Commission (FCC) Interference statement 2 CE Mark Warning 3 Chapter 1 – Wireless LAN Networking Transmission Rate 5 Type of Wireless Networks 5 Ad-Hoc (IBSS) Network 5 Infrastructure (BSS) Network 6 Wireless LAN Security 9 Data Encryption with WEP 10 Chapter 2 - Getting Started About Your Super G USB 2.0 WLAN Adapter 11 Package Content 11 System Requirement 11 LED Definition 11 Wireless Utility and Adapter Hardware Installation 12 Using the Utility to Configure Your Network 16 Link Information 16 Site Survey 17 Profile 19 Chapter 3 – Maintenance Uninstalling the Driver 24 Uninstall the Client Utility 24 Upgrading the Wireless Utility 24 Glossary 25 5 Chapter 1- Wireless LAN Networking This section provides background information on wireless LAN networking technology. T HE INFORMATION IN THIS SECTION IS FOR YOUR REFERENCE. CHANGING NETWORK SETTINGS AND PARTICULARLY SECURITY SETTTINGS SHOULD ONLY BE DONE BY AN AUTHORIZED ADMINISTRATOR. Transmission Rate (Transfer Rate) The adapter provides various transmission (data) rate options for you to select. Options include Fully Auto, 1 Mbps, 2 Mbps, 5.5 Mbps, 11 Mbps, 6 Mbps, 9 Mbps, 12 Mbps, 18 Mbps, 22 Mbps, 24 Mbps, 36 Mbps, 48 Mbps, 54 Mbps and 108 Mbps. In most networking scenarios, the factory default Fully Auto setting proves the most efficient. This setting allows your adapter to operate at the maximum transmission (data) rate. When the communication quality drops below a certain level, the adapter automatically switches to a lower transmission (data) rate. Transmission at lower data speeds is usually more reliable. However, when the communication quality improves again, the adapter gradually increases the transmission (data) rate again until it reaches the highest available transmission rate. Types of Wireless Networks Wireless LAN networking works in either of the two modes: ad-hoc and infrastructure. In infrastructure mode, wireless devices communicate to a wired LAN via access points. Each access point and its wireless devices are known as a Basic Service Set (BSS). An Extended Service Set (ESS) is two or more BSSs in the same subnet. In ad hoc mode (also known as peer-to-peer mode), wireless devices communicate with each other directly and do not use an access point. This is an Independent BSS (IBSS). To connect to a wired network within a coverage area using access points, set the adapter operation mode to Infrastructure (BSS). To set up an independent wireless workgroup without an access point, use Ad-hoc (IBSS) mode. A D-HOC (IBSS) NETWORK Ad-hoc mode does not require an access point or a wired network. Two or more wireless stations communicate directly to each other. An ad-hoc network may sometimes be referred to as an Independent Basic Service Set (IBSS). To set up an ad-hoc network, configure all the stations in ad-hoc mode. Use the same SSID and channel for each . When a number of wireless stations are connected using a single access point, you have a Basic Service Set (BSS). 6 7 In the ESS diagram below, communication is done through the access points, which relay data packets to other wireless stations or devices connected to the wired network. Wireless stations can then access resources, such as a printer, on the wired network. 8 In an ESS environment, users are able to move from one access point to another without losing the connection. In the diagram below, when the user moves from BSS (1) to BSS (2) the adapter automatically switches to the channel used in BSS (2).
