3 Configuration Utility The Configuration Utility is a powerful application that helps you configure the 802.11g Wireless LAN Mini USB Adapter and monitor the link status during the communication process. The Configuration Utility appears as an icon on the system tray of W indows while the card is running. You can open it by double-click on the icon. Right click the icon, there are some items for you to operate the configuration utility.
Parameter Description Mode Station – Set the USB adapter a wireless client. Access Point – Turns the USB adapter to function as a wireless AP. Please refer to Section 3.5 for the AP settings. Network Adapter Display the product information of the USB Adapter. Available Network Display all the SSID and Signal Strength of wireless devices nearby. To re-survey the available wireless devices please click “Refresh”.
Parameter Description Signal Strength This bar shows the signal strength level. The higher percentage shown in the bar, the more radio signal been received by the adapter. This indicator helps to find the proper position of the adapter for quality network operation. Link Quality This bar indicates the quality of the link. The higher the percentage, the better the quality. TX Frame It shows the number of data frames which are transmitted by the adapter successfully.
Parameter Description General Connection Setting Channel Select the number of the radio channel used for the networking. The channel setting of the wireless devices within a network should be the same. Tx Rate There are several options including Auto/1/2/5.5/11/6/9/12/18/24/36/48/54Mbps for you to select. When the “Auto” is selected, the device will choose the most suitable transmission rate automatically.
Parameter Encryption Description AES – AES has been developed to ensure the highest degree of security and authenticity for digital information and it is the most advanced solution defined by IEEE 802.11i for the security in the wireless network. Note: All devices in the network should use the same encryption method to ensure the communication. Authentication Mode This setting has to be consistent with the wireless networks that the adapter intends to connect.
Parameter Description Encryption Setting In the block, users setup W EP and WPA functions. Please refer to Section 3.3 for more description. W EP Encryption Key Click this button to setup the W EP key. Please refer to Section Setting 3.3 for the details. W PA Encryption Setting Click this button to setup the W PA function. Please refer to Section 3.3 for the details. Profile Profile Name You can save the network setting as a profile.
3.3.1 WEP Setting Parameter Description Key Length You may select the 64-bit, 128-bit or 256-bit to encrypt transmitted data. Larger key length will provide higher level of security, but the throughput will be lower. Default Key ID Select one of the keys (1~4) as the encryption key. Key Format Hexdecimal – Only “A-F“, “a-f“ and “0-9“ are allowed to be set as WEP key. ASCII –Numerical values, characters or signs are allowed to be the WEP key. It is more recognizable for user.
3.3.2 WPA Setting The adapter can automatically detect the WPA setting of the AP which the adapter chooses to connect from the “Available Network“ list. To connect to the AP, you should setup the same settings with the AP. There are two kinds of WPA mode: W PA and WPA-PSK. W PA is designed for enterprise which requires a RADIUS Server and Certificate Server for the authentication. WPA-PSK is a special mode designed for home and small business users who do not have access to network authentication servers.
Parameter Description Connect Information It is the setting for W PA or WPA-PSK mode. Protocol This adapter supports two kind of protocol for authentication including TLS and PEAP. TLS and PEAP requires a certificate which is provided by the Certificate Server. PEAP requires a set of user name and password in addition. To get the certificate and the personal user name and password, please contact with your administrator. TLS – Select a certificate from the “Certificate“ list.
3.4 Advanced Setting The “Advanced Setting” allows user to enable/disable country roaming, setup power consumption, fragmentation threshold and RTS/CTS threshold of the adapter. Parameter Description User Interface Select the display language of the utility. Two languages are enabled including English and Traditional Chinese. Country Roaming IEEE 802.
Parameter Description Fragementation Threshold The value defines the maximum size of packets, any packet size larger than the value will be fragmented. If you have decreased this value and experience high packet error rates, you can increase it again, but it will likely decrease overall network performance. Select a setting within a range of 256 to 2346 bytes. Minor change is recommended. RTS / CTS Threshold Minimum packet size required for an RTS/CTS (Request To Send/Clear to Send).
Parameter Description Network Adapter Display the product information of the USB Adapter. Connect Station List Display all the MAC Addresses of the wireless stations connecting to the AP. Current Network Setting Display the connection setting of the current network. It includes Channel, SSID, W EP and TX Power Level. More Setting For setting more functions including disable/enable W EP, MAC Address Filter and Bridge Adapter, etc. Please refer to Section 3.5.2.
Parameter Description General Connection Setting Channel Select the number of the radio channel used by the AP. The wireless stations which connect to the AP should set up the same channel. Basic Rate Select the basic data transmission speed supports by the AP. When the AP works in 11b mode, the maximum data rate is 11Mbps so that there are two options including “1, 2 Mbps (Mixed Mode)“ and “1, 2, 5.5, 11Mbps (Mixed Mode)” you can select.
Parameter Description Fragement The value defines the maximum size of packets, any packet size larger than the value will be fragmented. If you have decreased this value and experience high packet error rates, you can increase it again, but it will likely decrease overall network performance. Select a setting within a range of 256 to 2346 bytes. Minor change is recommended. RTS / CTS Minimum packet size required for an RTS/CTS (Request To Send/Clear to Send).
Parameter Description Filter Type Disable – Disable the MAC Address filter function. Accept – Only the wireless stations with the MAC Addresses setup in the table can connect to the AP. Reject – The wireless stations with the MAC Addresses setup in the table will be rejected to connect to the AP. Filter MAC Address MAC Address is a unique identification for hardware devices in the network. It is a 12-digit hexadecimal values. There are fifteen sets of MAC Addresses can be setup in the table.
4 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.
5. 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. 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.
12. 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 spreadspectrum (DSSS) generates a redundant bit pattern for each bit to be transmitted.
