First, either enable or disable encryprion from the appropriate “Encryption” field (see Figure 4-5 below). If you decide to use encryption, you can choose any of the available WEP keys (1 to 4). You also have the option to select the WEP mode (Mandatory/Optional). If you select “Mandatory”, then not only WEP will be used, but also any other station needs to use WEP encryption in order to establish a communication with your station. This requirement is in line with the IEEE 802.11b standard. If, on the other hand, you choose “Optional”, then your station can communicate with every other station regardless if they use WEP or not. Please keep in mind that the WEP keys must be in HEX format. Finally, you have the option to select whether Open System or Shared Key authentication will be used. In order to take effect the changes you wish to make, press the “Submit” button at the bottom of the screen. Figure 4-5. Encryption Advanced By Choosing the Advanced option in any of the two modes, you can change advanced configuration settings, such as the Preamble Type, Fragmentation Threshold, and RTS/CTS Threshold (Figure 4-6). Figure 4-5 shows the recommended configuration for the advanced settings. Before selecting Short Preamble, make sure that the other stations and APs are also supporting this feature. Note: The USB (A) card has an auto-detection feature therefore it automaticatilly selects the Preable Type depending on the Access Point Preamble type. In order to enable the Fragmentation and the RTS/CTS Threshold parameters move the slide bar with your mouse and then use the right and left arrow keys of your keyboard in order to select an exact number. Figure 4-6. Advanced Settings Version By choosing this option, you can view basic information about the Utility like the Driver, Firmware and Application Version.
