1 Introduction Thank you for purchasing Wireless LAN USB Adapter. 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-freely. Using radio frequency (RF) technology, WLAN devices 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 Configure as: Ad Hoc wireless LAN or Infrastructure wireless LAN. Ad Hoc network is a group of notebooks with wireless LAN adapter, called a BSS (Basic Service Set). These notebooks use their wireless LAN adapter to communicate with each other directly.
3 Drivers and Utility Installation This section describes the procedures for installing the Wireless LAN USB Adapter. Before You Start Before installation, please check your system in advance and ensure it meets the minimum requirements as described below.
1.Insert the installation & driver CD to your CD-ROM, It will auto run installation program. 2. Click “ Next” to continue.
3. Click “ Next” to install at the designated folder. Or, click “ Browse” to select different folder. 4. Start copying files until it finish the installation.
5. Plug the USB adapter into the USB of your PC. When Windows is ready to configure the new hardware, it opens the “ Found New Hardware Wizard” dialog box as shown below. Select “ Install the software automatically (Recommended)” and click “ Next” to continue. 6. The Wizard is searching the driver.
7. Start copying the driver 8.Click “ Finish” to complete the Setup.
4 Wireless Network Configuration WLAN USB Adapter uses its own management software. All functions controlled by users are provided by this application. When you insert the WLAN USB Adapter into the USB Adapter slot, a new icon, , should appear in the Windows System Tray automatically. If the icon is in red, it means that WLAN USB Adapter configuration is invalid or incomplete. Double click that icon and the configuration window will pop up as shown below. It shows the SSID of available network.
Current Network Information displays the current network configuration. If you want to change network configuration, click “ More Setting” . In this panel, you can modify the general network connection setting, enable/disable the WEP, load/modify profile and other setting. Through this control panel, you will be able to access the corporate wireless LAN or hot spots such as hotel, airport, and conference hall.
4.1 General Connection Setting Click ” Apply” to modify SSID, network type or select Transmit rate. 4.2 Encryption Setting You may want an additional measure of security on your wireless network, which can be achieved by using WEP (Wired Equivalent Privacy) encryption. WEP encrypts each frame transmitted from the radio using one of the Keys entered in this panel. When an encrypted frame is received it will only be accepted if it decrypts correctly.
In Shared Key system, the station and Access Point are authenticated each other. The data frame is also encrypted by the WEP key. In Auto Mode, the Access Point takes control of network security setting and station will follow the setting required from AP. Click the close icon of “ WEP Key Setting” windows and return to the main page of Configuration Tool. 4.3 Profile Each profile represents specific settings of the USB adapter. You can set the settings for each profile.
4.4 Advanced Setting Click “ Advanced Setting” to enable power saving mode that has 5 different levels. It also allows you to set the threshold of fragmentation and CTS/RTS. 4.5 System Information Click “ Information” and the pop-up window will show the Driver Version, Firmware Version, MAC address of this USB adapter and so on.
5 Technical Specifications of WLAN USB Adapter Product Name 11b WLAN USB Adapter Standard IEEE802.11b Frequency Band 2.400GHz ~ 2.4835GHz unlicensed ISM band Spread Spectrum DSSS (Direct Sequence Spread Spectrum) Modulation method DQPSK/DBPSK/CCK Data Rate 1Mbps, 2Mbps, 5.
6 Glossary IEEE 802.11 Standard The IEEE 802.11 Wireless LAN standards subcommittee, which is formulating a standard for the industry. 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. Ad Hoc wireless LAN is applicable at a departmental scale for a branch or SOHO operation.
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.
SNMP, agents-which can be hardware as well as software-monitor the activity in the various devices on the network and report to the network console workstation. Control information about each device is maintained in a structure known as a management information block. Static IP Addressing A method of assigning IP addresses to clients on the network. In networks with Static IP address, the network administrator manually assigns an IP address to each computer.
