For information on installing the Cisco Aironet Client Utility (ACU) to enable Light Extensible Authentication Protocol (LEAP) or Extensible Authentication Protocol (EAP) for Microsoft Windows 95, 98, NT, 2000, and Me, refer to Installing the Client Adapter.

  • Step 1 Make sure the client adapter is not inserted in your computer. You will be instructed when to insert it.

Special attention should be paid to the use of strong passwords. Cisco LEAP is a password-based algorithm. To minimize the possibility of a successful dictionary attack, use strong passwords, which are difficult to guess. Some characteristics of strong passwords include:

  • A minimum of ten characters
  • A mixture of uppercase and lowercase letters    
  • At least one numeric character or one non-alphanumeric character (example: !#@$%)   
  • No form of the user's name or user ID   
  • A word that is not found in the dictionary (domestic or foreign)
