  • Page 14: Configuration Utility

    3 Configuration Utility The Ralink Configuration Utility is a powerful application that helps you configure the USB adaptor and monitor the link status and the statistics during the communication process. When the adaptor is installed, the configuration utility will be displayed automatically. This adaptor will auto connect to wireless device which has better signal strength and no wireless security setting.
  • Page 15 In Windows XP, there is a “Windows Zero Configuration Tool” for you to setup wireless clients. If you want to switch to use Ralink configuration utility, please follow one of the ways as below. First Way Right click the icon in the system tray and select “Use RaConfig as Configuration utility”. Second Way A.
  • Page 16 C. Uncheck “Use Windows to configure my wireless network settings” to enable the utility for the adaptor. Note: If “Wireless Zero Configuration” is enabled, you can only configure the advance setting or check the link status and statistics from the configuration utility of the adaptor.

  • Page 17: Site Survey

    3.1 Site Survey When you open the Ralink Configuration Utility, the system will scan all the channels to find all the access points/stations within the accessible range of your adaptor and automatically connect to the wireless device with the highest signal strength. From the “Site Survey”, all the networks nearby will be listed. You can change the connection to another networks or add one of the networks to your own Parameter Available Description This list shows all available wireless networks within range...

  • Page 18: Profile

    3.2 Profile The “Profiles List” is for you to manage the networks you connect to frequently. You are able to Add/Delete/Edit/Activate a profile. Parameter Profiles List Description The profiles list display all the profiles and the relative settings of the profiles including Profile Name, SSID, Channel, etc. This sign indicates the activated profile is been connecting.

  • Page 21: Authentication And Security

    Parameter Description RTS Threshold Minimum packet size required for an RTS (Request To Send). For packets smaller than this threshold, an RTS is not sent and the packet is transmitted directly to the wireless network. Select a setting within a range of 0 to 2347 bytes.
  • Page 22 Parameter Description Authentication Type LEAP – LEAP is a pre-EAP, Cisco-proprietary protocol, with many of the features of EAP protocols. Cisco controls the ability of other vendors to implement this protocol, so it should be selected for use only when limited vendor choice for client, access-point, and server products is not a concern.
  • Page 23 Parameter Description Encryption Mode None – Disable the encryption mode. 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 ensures much greater security than the standard WEP security.
  • Page 24 The IEEE 802.1X specification describes a protocol that can be used for authenticating both clients and servers on a network. The authentication algorithms and methods are those provided by the Extensible Authentication Protocol (EAP), a method of authentication that has been in use for a number of years on networks that provide Point-to-Point Protocol (PPP) support as many internet service providers and enterprises do.

    3.2.1.3 802.1x Setting-Certification Parameter Description Authentication Type The EAP authentication protocols this adaptor has supported are included as follows. This setting has to be consistent with the wireless APs or Routers that the adaptor intends to connect. PEAP &TTLS – PEAP and TTLS are similar and easier than TLS in that they specify a stand-alone authentication protocol be used within an encrypted tunnel.
  • Page 26 Identity This is the protected user EAP Identity used for authentication. The identity specified may contain up to 63 ASCII characters, is case sensitive and takes the form of a Network Access Identifier, consisting of <name of the user>@<user’s home realm>. The user’s home realm is optional and indicates the routing domain.

    If you want to know the signal strength in the unit of dBm, select this check box. Signal Strength This bar shows the signal strength level. The higher percentage shown in the bar, the more radio signal been received by the adaptor. This indicator helps to find the proper position of the wireless device for quality network operation.
  • Page 29 Parameter Description Wireless Mode 802.11 B/G mix – If you have a mix of 802.11b and 802.11g wireless stations in your network, it is recommended to set the adaptor to this mode. This mode is also the default setting. 802.11 B only – This adaptor can be compatible with both 802.11g and 802.11b wireless stations.
  • Page 30 automatically. The higher data rate you designated in the network, the shorter distance is allowed between the adaptor and the wireless stations. When the wireless mode is “802.11 B only”, the maximum data rate is 11Mbps (11b) so that there are only “Auto/1/2/5.5/11Mbps” options you can select.
