2 Installation Procedure Before you proceed with the installation, please notice following descriptions. Note: The following installation was operated under Windows XP. (Procedures are similar for Windows 98SE/Me/2000.) Note: The driver of Windows 2000 can only support Windows 2000 Service Pack 3 above. I. Install the Driver A. Insert the Installation CD into your CD-ROM driver. B. Insert the USB adapter to the USB port of your laptop or desktop PC. C.
F. The wizard will install the driver automatically. Click “Finish” to complete the installation. II. Install the Utility A. Execute the "Utility\setup.exe" program from the installation CD. B. The installShield Wizard box will appear, click “Next” to continue. D. C. Choose the selection “I accept the terms in the license agreement” and click “Next”. 4 Enter your “User Name” and “Organization” which is only for reference, then click “Next”.
E. If you want to change the destination folder, click “Change”, or click “Next” to continue. F. The wizard has installed the driver automatically. Click “Finish” to complete the installation.
III. Using the Utility Go to Start\All Programs\Envara Configuration Utility and select “Envara Configuration Utility”. You are able to use the utility.
3 Configuration Utility The Configuration Utility is a powerful application that helps you configure the adapter and monitor the link status and the statistics during the communication process. However, there are some restrictions on the utility. Before using the utility, you have to know about them. 1. If you want to connect to 11g (up to 54Mbps) network, please ensure to install the adapter to PC or laptop with USB 2.0 interface. This adapter can only support 11b while you connect it to the USB 1.1/1.
Parameter Description Connected to (SSID) Display the wireless network which the adapter is connecting to. Network Mode There are two sorts of network types: Infrastructure and Ad Hoc. This field shows the current network type. Channel / Frequency Display the number of the radio channel and the frequency used for the networking. Max. Network Rate This field shows the maximum link rate of the network, that is 54Mbps for 802.11g and 11Mbps for 11b.
Parameter Description View Site Button To view the available network nearby, click the “View Site” button. 3.1.1 Preference Setting This preference screen enables you to change the unit of link quality or the update interval for transmitted and received data. The default settings is “10” for “Statistics Update Interval” and “Percent” for “Parameter Display Units”. If you want to set up as default values, click “Defaults”. This preference setting also enables you to change the “Country Code”.
Parameter Description Available Networks/AP’s List In the list, you can know the information of wireless networks including Link Quality, Network Name, Mode, Security, etc. This information will help you to decide which network you want to connect. Connect Button Select one of the networks from the list and click “Connect”, the adapter will connect to the network automatically. You can also right click the network and select “Connect”. Save Profile Button Save the selected network to be a profile.
Parameter Description Auto-Selection Profiles If a profile is set as an Auto-Selection profile it is used to attempt to automatically connect the adapter to the respective profile in the order of the appearance at startup. The networks ever been connected by the adapter will display in the profile list. If you want to connect to one of the profiles in the list, double-click the item on the list or right click the network and select “Connect”.
3.2.1 Configure the Profile When you click “New” or “Edit”, the “Profile Configuration” screen will be popped up. In the screen, there are two pages including General and Security. General Parameter Description Name To name a recognizable profile name for you to identify the different networks. Network Name (SSID) The SSID (up to 32 printable ASCII characters) is the unique name identified in a WLAN. The ID prevents the unintentional merging of two co-located WLANs.
Parameter Description Channel / Frequency This setting is only available for Ad Hoc mode. The channel setting should be the same with the network you are connecting to. Auto-Select Profile Member If you select the check box, this profile will be put in the “Auto-Selection Profiles” list. Defaults The default values are Ad Hoc mode and channel one. If you want to set up to default, click this button. Encryption Parameter Description Security None – Disable the WEP Data Encryption.
Parameter Description Encryption Key (Key1 ~ Key4) Select the default encryption key from Key 1 to Key 4 by selected the radio button. The WEP keys are used to encrypt data transmitted in the wireless network. Fill the text box by following the rules below. 64-bit – Input 10-digit Hex values (in the “A-F”, “a-f” and “0-9” range) as the encryption keys. For example: “0123456aef“. 128-bit – Input 26-digit Hex values (in the “A-F”, “a-f” and “0-9” range) as the encryption keys.
3. Click “Configure” to configure the WPA function for the current network. Parameter Description Network Authentication Open –No authentication is needed among the wireless network. Shared – Only wireless stations using a shared key (WEP Key identified) are allowed to connecting each other. WPA – This mode is for enterprise with an authentication server (Radius Server), WPA-enabled access point, and a WPA-enabled client.
Parameter Description Data Encryption WEP – In WPA or WPA-PSK mode, WEP is also able to be the encryption method for the transmission data. TKIP – TKIP (Temporal Key Integrity Protocol) changes the temporal key every 10,000 packets (a packet is a kind of message transmitted over a network.) This insures much greater security than the standard WEP security. Note: All devices in the network should use the same encryption method to ensure the communication. 3.

4 Troubleshooting This chapter provides solutions to problems usually encountered during the installation and operation of the adapter. 1. Why can’t the USB adapter work or only work in 11b mode while connect to USB 2.0 port? If this situation occurs, please upgrade the driver of your USB port. This problem may be the compatibility issue with the old driver of the USB port. 2. What is the IEEE 802.11g standard? 802.
6. What is Infrastructure? An integrated wireless and wireless and wired LAN is called an Infrastructure configuration. Infrastructure is applicable to enterprise scale for wireless access to central database, or wireless application for mobile workers. 7. What is BSS ID? A specific Ad hoc LAN is called a Basic Service Set (BSS). Computers in a BSS must be configured with the same BSS ID. 8.
13. What is DSSS?What is FHSS?And what are their differences? Frequency-hopping spread-spectrum (FHSS) uses a narrowband carrier that changes frequency in a pattern that is known to both transmitter and receiver. Properly synchronized, the net effect is to maintain a single logical channel. To an unintended receiver, FHSS appears to be short-duration impulse noise. Direct-sequence spread-spectrum (DSSS) generates a redundant bit pattern for each bit to be transmitted.
