Confirm Box Contents Wireless LAN Adapter Driver CD Quick Start Guide CONNECTING YOUR WLAN USB ADAPTER TO PC Connect your WLAN USB dongle to your PC. Install driver. GETTING TO KNOW WIRELESS LAN USB ADAPTER LED LED turns on when POWER is applied to the WLAN Mini USB Adapter. LED is blinking when PC is sending data through WLAN Mini USB Adapter. 2 WIRELESS LAN BASICS Wireless LAN network defined by IEEE 802.11b/g standard committee could be configured as : Ad Hoc wireless LAN, or Infrastructure wireless LAN. Ad Hoc network is a group of PCs installed with wireless LAN cards, this group of PCs is called a BSS (Basic Service Set). PCs in this group can use their wireless LAN cards to communicate with each other, but can not connect to the Internet. STA 2 STA 1 STA 3 Ad Hoc Wireless Network Infrastructure Wireless Network The most obvious difference between Infrastructure wireless network and Ad Hoc wireless network is that the PCs in Infrastructure wireless network can access the resource in the Internet through Access Point. Depending on your requirement, you can easily set up your PC's network to be a "Ad Hoc" or "Infrastructure" wireless network. Generally speaking, if in your network, there is an Access Point in it, we recommend you to set your network as an "Infrastructure", so it can connect to the Internet. 3 IP ADDRESS To use the WLAN Mini USB Adapter with a computing device, the WLAN Mini USB Adapter must be equipped with an USB 1.1 or 2.0 Interface. All drivers and supporting software for the WLAN Mini USB Adapter must be installed and configured first. Ask your system administrator for the following information, which you may need to provide during driver installation : Your Wireless Client Name. Your Wireless SSID. Your computer's unique client name and workgroup name. For your network account, your user name and password. Your IP address, gateway address, and subnet mask if you're not using a DHCP server. Any computer on a network is identified by a unique network address. There are two methods to assign a network address to a computer on a TCP/IP network : Static IP addressing. Dynamic IP addressing (DHCP). In network with static IP addressing, the network administrator manually assigns an IP address to each computer. Once a static IP address is assigned, a computer uses the same IP address every time it reboots and logs on to the network. You may manually change the IP address in the Network Properties dialog box. Network using static IP address is easy to set up and do not require additional network management software. In network with dynamic IP addressing, a DHCP server in the network dynamically assigns IP addresses to all clients every time they log on to the network. Network using dynamic IP address requires setting up and running a DHCP Server. 4 INSTALL DRIVER / UTILITY The installation & driver CD will automatically activate the autorun installation program after you insert the disk into your CD drive. Step 1 : Insert the installation & driver DC into your CD-ROM. Step 2 : Click Next to continue. Step 3 : Click Next to install at the designated folder. Or, click "Browse" to select different folder. 5 Step 4 : Start copying files until it finishes the installation. Step 5 : Click Finish to complete installation. Step 6 : After finished install driver and utility on your system, plug the USB adapter into the USB port of your PC. Windows XP/2000 will automatically detect the USB Adapter. 6 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 port of your PC, 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 on that icon and the configuration window will pop up as shown below. It shows the SSID of available network. Once a network is chosen, the signal strength and link quality are displayed. The Link Quality and Signal Strength bar chart is only active when the node is in Infrastructure Mode. The bar graph displays the quality and strength of the link between the node and its Access Point. Link Quality is a measurement of receiving and transmitting performances over the radio. Tx/Rx Frame displays the instantaneous wireless Transmit and Receive throughput in bytes per second. These values are updated every two seconds. The Configuration Tool contains several fields where operating parameters of the driver can be viewed or changed. Changes to any of the parameters in this panel can be applied to the driver without a need to restart the computer. Current Network Information displays the current network configuration. If you want to change network configuration, click "More Setting". 7 5.1 GENERAL CONNECTION 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. Click "Change" to start input of settings. The settings include : SSID. Network Type. Transmit Rate. Encryption. Authentication Mode. When settings are input, click "Apply" to confirm changes of them. 8 5.2 WEP ENCRYPTION KEY 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. This will only happen if the receiver has the same WEP Key used by the transmitter. The default state in Encryption Setting is WEP disabled. Check "Enable WEP" to enable the encryption. For more WEP key setting, Click "WEP Encryption Key Setting". Three authentication modes are available: Open System, Shared Key and Auto. The Open System uses default key to authenticate the station and Access Point. Once both parties are authenticated, the station is allowed to send and receive data from the network. However, the data are not encrypted. 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 box" at the upper right hand corner to return to Configuration Tool. 9 5.3 WPA ENCRYPTION SETTING WPA (Wi-Fi Protected Access) is a security technology for wireless networks. WPA improves on the authentication and encryption features of WEP (Wired Equivalent Privacy). To improve data encryption, WPA utilizes its Temporal Key Integrity Protocol (TKIP). TKIP provides important data encryption enhancements including a per-packet key mixing function, a message integrity check (MIC, named Michael), an extended initialization vector (IV) with sequencing rules, and a rekeying mechanism. WPA Pre-Shared Key (WPA-PSK) is a simplified but still powerful form of WPA most suitable for home Wi-Fi networking. To us ...
