1. Introduction Thank you for purchasing your Wireless Local Area Net (WLAN) USB Dnogle. You are about to install a networking system that is not only fast and powerful, but also easy to set up and simple to maintain. In a short time you and those in your network will be able to share a local printer and files, access the Internet, and roam about the office wire-free. Using radio frequency (RF) technology, WLANs transmit and receive data over the air, minimizing the need for wired connections.
2. Wireless LAN basics Wireless LAN network defined by IEEE 802.11b standard committee could be configured as: • Ad Hoc wireless LAN or • Infrastructure wireless LAN Ad Hoc network is a group of notebooks with WLAN PC cards or USB dongles called a BSS (Basic Service Set). These notebooks use their WLAN PC cards or USB dongles to communicate with each other, and notebooks can not connect to the Internet.
3. Windows Installation The following section will assist you to install Wireless LAN USB successfully. You will first install software (driver) and then connect the Wireless LAN USB, and finally set the network properties to accommodate resource sharing and select the type of wireless network that you wish to install. The Wireless LAN can easily be installed and used, without bothering to connect cables for keeping your computer to use network resources, as in case of wired LAN.
3.1 Installation and Configuration Procedures Under Windows 98 SE Please follow the following steps one by one in order to install the WLAN USB Dongle successfully. Step 1. Power on your computer and allow Windows 98 SE to load fully. Be sure that there is no USB dongle is connected to computer yet. Insert the given documentation CD and then double click the MY Computer icon on your desktop. In my computer window, double click the CD Drive icon.
Click Next to continue. Step 2. Software License Agreement, click Yes to accept.
Step 3. Select Adapter Type. Please select Application & USB Drivers then click Next. Step 4. Click Next to search for already installed components.
Step 5. Search for already installed components Step 6. Choose Destination Location.
Step 7. Setup will add program icons to the Program Folder listed below. You may type a new folder name, or select one from the existing folders list. Click Next to continue. Step 8. Select operating mode. Ad hoc mode provides communication between wireless clients. Infrastructure mode provides communication between wired and wireless clients (Requires an access point). Select Infrastructure then click Next.
Step 9. ESSID is the name of a logical network group that your computer is about to join. (It can be changed again at run time by the configuration utility). . Step 10. Click Next to start copying files.
Step 11. Step Status Step 12. Click Finish to exit the wizard.
3.2 Configuration Utility WLAN USB dongle uses its own management software. All functions controlled by user are provided by this application. When you plug WLAN USB dongle into the USB port, a new iconshould appear in your icon tray automatically wait a while. If the icon is in red, it means that WLAN USB Dongle configuration is invalid or incomplete. Double click on that icon the screen is shown below. User can navigate through “cards”, by clicking or tapping them with a stylus.
“Change” / “Submit” button This button becomes active only when one of the fields has been modified. Pressing “Change” button applies the changed values to the driver. Than pressing “Submit” button saves them to the registry. Network Mode This field allows you to select from a list of supported Network “Modes”. The modes displayed will have two values: “Ad Hoc” and “Infrastructure”. Ad Hoc - This is the 802.11b peer-to-peer mode of operation.
Statistics To check the packets status, uses can press the “Statistics” tab and get related statistical figures of data and management packets.
Site Survey Click on the site survey tab, all access point within detectable range will be found and their related information will be displayed.
Encryption An encryption function can avoid unintended users who are not at the same wireless LAN user group to access or get information. The “Encryption” options allow you to enable 64-bit or 128-bit WEP (wired equivalent privacy) encryption. If an encryption function is not needed, you can just simply tick on the “Disable” box to disable it. By choosing this option you must defi ne the encryption key values of your choice.
Advanced In advanced tab, you can change configuration setting such as Preamble Type, Fragmentation Threshold, and RTS/CTS Threshold. Before selecting Short Preamble, make sure that the other stations and AP’s are also supporting this feature. Preamble Type (Short/Long) Preamble is the first subfield of PPDU, which is the appropriate frame format for transmission to PHY (Physical layer). There are two options, Short Preamble and Long Preamble. The Short Preamble option improves throughput performance.
Version Version tab shows the product version including the detail of driver, firmware and application version. Users must use this version number when reporting their problems for technical support.
4. Technical Specifications of WLAN USB Dongle Driver Supported Microsoft Windows 98 / Windows 98 SE / Windows ME / Windows 2000 Standards Supported IEEE 802.11b standard for Wireless LAN Radio Specifications Frequency Range: 2.4-2.
Glossary IEEE 802.11 Standard The IEEE 802.11 Wireless LAN standards subcommittee, which is formulating a standard for the industry. The objective is to enable wireless LAN hardware from different manufacturers to enteropera. Access Point An internetworking device that seamlessly connects wired and wireless networks together. Ad Hoc An Ad Hoc wireless LAN is a group of computers, each with a WLAN adapter, connected as an independent wireless LAN.
Gateway A gateway is a hardware and software device that connects two dissimilar systems, such as a LAN and a mainframe. In Internet terminology, a gateway is another name for a router. Generally a gateway is used as a funnel for all traffic to the Internet. IEEE Institute of Electrical and Electronics Engineers Infrastructure An integrated wireless and wired LAN is called an Infrastructure configuration.
Roaming In an infrastructure network, this is when a wireless PC moves out of range of the previously connected access point and connects to a newly connected access point. Throughout the network environment where access point are deployed, PCs can always be connected regardless of where they are located or roam. SSID A Network ID unique to a network. Only clients and Access Points that share the same SSID are able to communicate with each other. This string is case-sensitive.
Wireless LAN (WLAN) A wireless LAN does not use cable to transmit signals, but rather uses radio or infrared to transmit packets through the air. Radio Frequency (RF) and infrared are the commonly used types of wireless transmission. Most wireless LANs use spread spectrum technology.
