4 Configuration Utility The Configuration Utility is a powerful application that helps you configure the Wireless LAN USB Adapter and monitor the link status and the statistics during the communication process. The Configuration Utility appears as an icon on the system tray and desktop of Windows. You can open it by double-click on the icon. In the Desktop In the System Tray Right click the icon in the system tray there are some items for you to operate the configuration utility.
3.1 Utility Overview There are several parts in the utility screen. Please refer to the following table for the description. A E B C D Parameter A B C Description Refresh – Refresh adapter list in the “B“ block. SetWizard – Open the setup wizard for quick start the wireless connection. Mode – There are two modes: Station and Access Point. If “Station“ is selected, the adapter works as a wireless adapter. If “Access Point“ is selected, the adapter will works as a wireless AP.
Parameter Description D It is the status bar that displays the current status of the utility. To close it, please disable the “Status Bar“ in the “View“ item. E There are several tabs in the block for you to setup the function of the adapter. Please refer to the description in the following sections.
3.2 Available Network When you open the Configuration Utility, the system will scan all the channels to find all the access points/stations within the accessible range of your adapter and automatically connect to the wireless network with the highest signal strength. From the “Available Network” tab, all the networks nearby will be listed. You can change the connection to another network.
3.3 General To check the connection status of the adapter, select “General“. This screen shows the information of Link Speed, Network Type, Encryption Method, SSID, Signal Strength, Link Quality and Network Address of the adapter. Parameter Description Status It will show the connection status of the adapter. Speed It shows the current speed Type Infrastructure – This operation mode requires the presence of an 802.11 Access Point. All communication is done via the Access Point or Router.
Parameter Description Signal Strength It indicates the wireless signal strength. Link Quality It indicates the wireless link quality. Network Address It shows the MAC, IP address and other information of the adapter. Renew IP Click this button to renew the network address settings of the adapter.
3.4 Profile The “Profiles List” is for you to manage the networks you connect to frequently. You are able to Add/Remove/Edit/Duplicate/Set Default to manage a profile. Parameter Description Available Profile(s) This list shows the preferred networks for the wireless connection. You can add, remove, edit, duplicate the preferred networks or set one of the networks as the default connection. Add/ Remove/ Edit Button Click these buttons to add/ delete/ edit the selected profiles.
3.4.1 Configure the Profile Parameter Description This is a computer-to-computer There are two kinds of network type described as follows. (ad hoc) network; wireless access Infrastructure – This operation mode requires the presence of points are not used. an 802.11 Access Point. All communication is done via the Access Point or Router. Ad Hoc – Connect to another wireless adapter in the Wireless LAN network without through an Access Point or Router.
Parameter Description Channel This setting is only available for Ad Hoc mode. Select the number of the radio channel used for the networking. The channel setting should be the same with the network you are connecting to. Network Authentication This setting has to be consistent with the wireless networks that the adapter intends to connect. Note that in Windows Vista, the adapter only supports Open System, Shared Key, WPA-PSK and WPA2-PSK security methods.
WPA2 802.1X – Like WPA, WPA2 supports IEEE 802.1x/EAP authentication or PSK technology. It also includes a new advanced encryption mechanism using the Advanced Encryption Standard (AES). AES is required to the corporate user or government users. The difference between WPA and WPA2 is that WPA2 provides data encryption via the AES. In contrast, WPA uses Temporal Key Integrity Protocol (TKIP). WEP 802.1X – It’s a special mode for using IEEE 802.
Parameter Description Network Key The 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 as the encryption keys. For example: “0123456aef“. 128-bit – Input 26-digit Hex values as the encryption keys. For example: “01234567890123456789abcdef“. Confirm Network Key Enter the same network key to confirm.
3.5 Advanced The “Advanced” option enables you to configure more advanced settings, for example: Power Save, Turbo Mode, Wireless Mode and etc. Parameter Description Power Save None – The adapter will always set in active mode. Min – Enable the adapter in the power saving mode when it is idle, but some components of the adapter are still alive. In this mode, the power consumption is larger than “Max“ mode. Max – Enable the adapter in the power saving mode when it is idle.
Parameter Description Wireless Mode 802.11 b – This adapter can be compatible with both 802.11g and 802.11b wireless stations. If there are only 802.11b wireless stations in the network, you can set the adapter to this mode. 802.11 g/b – If you have a mix of 802.11b and 802.11g wireless stations in your network, it is recommended to setting the adapter to this mode. Preamble Mode The preamble defines the length of the CRC block for communication among the wireless stations.
Parameter Description Set Defaults Let the setting values return to default. Apply Confirm the settings in the “Advanced“.

3.8 Wi-Fi Protected Setup Wi-Fi Protected Setup (WPS) is the latest wireless network technology which makes wireless network setup become very simple. If you have WPS-enabled wireless access point, and you want to establish a secure connection to it, you don’t have to configure the wireless access point and setup data encryption.
3.9 Software AP This adapter can run as a wireless AP. Please pull down the “Mode” menu and select “Access Point”. The relative configurations of the AP including channel, SSID, WEP encryption and so on are described as follows.
Parameter Description 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. The default SSID of the AP is Full Computer Name + “_AP“. Wireless adapters connect to the AP should set up the same SSID as the AP. BSSID Display the MAC address of the adapter. Associate Table All the wireless adapters connected to the software AP will be displayed in the list.
3.8.2 AP Advanced Parameter Description Beacon Interval Beacon Interval that specifies the duration between beacon packets (milliseconds). The range for the beacon period is between 20-1000 milliseconds with a typical value of 100. DTIM Period Determines the interval the Access Point will send its broadcast traffic. Default value is 3 beacons. Preamble Mode The preamble defines the length of the CRC block for communication among the wireless network. There are two mode including Long and Short.
3.8.3 AP Statistics You can get the real time information about the packet transmission and receiving status during wireless communication from the screen. If you want to recount the statistics value, please click “Reset“.

5 Troubleshooting This chapter provides solutions to problems usually encountered during the installation and operation of the adapter. 1. What is the IEEE 802.11g standard? 802.11g is the new IEEE standard for high-speed wireless LAN communications that provides for up to 54 Mbps data rate in the 2.4 GHz band. 802.11g is quickly becoming the next mainstream wireless LAN technology for the home, office and public networks. 802.11g defines the use of the same OFDM modulation technique specified in IEEE 802.
6. 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. 7. What is WEP？ WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 40 bit shared key algorithm, as described in the IEEE 802 .11 standard. 8. What is TKIP? TKIP is a quick-fix method to quickly overcome the inherent weaknesses in WEP security, especially the reuse of encryption keys. TKIP is involved in the IEEE 802.
13. What is Spread Spectrum？ Spread Spectrum technology is a wideband radio frequency technique developed by the military for use in reliable, secure, mission-critical communication systems. It is designed to trade off bandwidth efficiency for reliability, integrity, and security.
