Parameter A B C D E Description Refresh – Refresh adapter list in the “B“ block. RT-Set – Open the RT-Set wizard. 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. View – Enable “Status Bar“ and the “D“ block in the utility will display the current status of the utility. About – To check the version of the utility, select this item.
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 Link Quality It indicates the wireless link quality. Network Address It shows the MAC, IP address and other information 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.
3.4.1 Configure the Profile Parameter Description Profile Name Define 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. You may specify a SSID for the adapter and then only the device with the same SSID can interconnect to the adapter.
Parameter Description Network Authentication This setting has to be consistent with the wireless networks that the adapter intends to connect. Open System – No authentication is needed among the wireless network. Shared Key – Only wireless stations using a shared key (WEP Key identified) are allowed to connecting each other. WPA 802.1X – WPA provides a scheme of mutual authentication using either IEEE 802.1x/Extensible Authentication Protocol (EAP) authentication or pre-shared key (PSK) technology.
Parameter Description Data Encryption Disabled – Disable the WEP Data Encryption. WEP – Enable the WEP Data Encryption. When the item is selected, you have to continue setting the WEP Encryption keys. 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.
Parameter Description EAP Type GTC – GTC is an authentication protocol which allows the exchange of clear text authentication credentials across the network. TLS – TLS is the most secure of the EAP protocols but not easy to use. It requires that digital certificates be exchanged in the authentication phase. The server presents a certificate to the client. After validating the server’s certificate, the client presents a client certificate to the server for validation.
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 Preamble Mode The preamble defines the length of the CRC block for communication among the wireless stations. There are three mode including Long, Short and Auto. High network traffic areas should use the shorter preamble type. If “Auto“ mode is selected, the adapter will auto switch the preamble mode depending on the wireless stations that the adapter is connecting to. Note that the parameter is only active in the Ad Hoc operation mode.
3.6 Status This screen shows the information of manufacturer, driver version, settings of the wireless network the adapter is connecting to, linking time and link status. If you don’t ensure the status of the adapter and the network you are connecting, please go to the screen for more details. 3.7 Statistics You can get the real time information about the packet transmission and receiving status during wireless communication from the screen.
3.8 Software AP This adapter can run as a wireless AP. 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.
3.8.1 AP Properties Setting Please refer to Section 3.4.1 for the setting of the parameters for AP. Note that Ad Hoc mode is not enabled for AP. 3.8.
