• IEEE 802.11i/WPA2 AES support
Enhanced Client Network Management Features
• Profile manager: Allows users to create specific profile settings for various environments, making it simple for telecommuters and business travelers to move from one environment to another.
• Customized profile settings: Lets users individually select the channel, service set identifier (SSID), Wired Equivalent Privacy (WEP) key, and authentication method for different locations.
• Cisco LEAP authentication status screen: Provides status updates regarding the Cisco LEAP authentication process.
• Auto-selection of profiles: Provides automatic selection of established profiles, including those configured for EAP authentication, without requiring storage of the EAP username and password in the profile.
• System tray icon: Provides easy access to wireless LAN connection information and one-click access to common actions, such the manual selection a profile or turning the radio on or off.
• Cisco Aironet Client Monitor: Provides a subset of Cisco Aironet Desktop Utility features, such as status information about the client adapter and access to basic tasks (selecting a profile, for example). This application runs from the system tray icon.
• Troubleshooting utility: Provides step-by-step details on the process of connecting to an access point, as well as highlights on why a connection failed.
• Support for the most popular enterprise operating systems: Windows XP and Windows 2000.
• Cisco Aironet Client Adapter installation wizard for Windows: The wizard is provided for easy installation of the client firmware, drivers, and utilities and offers several installation options: install client utilities and driver; install driver only; or make driver installation diskette(s). For ease of use, the installation wizard image file is a self-extracting (.exe) file.
