    Instructions:

    A wireless LAN client adapter card must be installed or inserted into your Windows machine before beginning installation of the Aironet Client Adapter Installation Wizard file. Windows NDIS drivers and radio firmware can only be installed when a wireless LAN client adapter is available on the windows machine.

    After downloading the Aironet Client Adapter Installation Wizard file, double-click on the downloaded file. The file will self-extract and automatically determine your operating system and client adapter type - when a wireless LAN client adapter is properly installed.

    Individual loading of firmware, NDIS driver, or utilities (ACU, ACM or ADU) is not necessary when the Aironet Client Adapter Installation Wizard file is used. Please read the release notes for additional information.
