Key Strength Meter—The WAP device checks the key against complexity criteria such
as how many different types of characters (uppercase and lowercase alphabetic letters,
numbers, and special characters) are used and how long the string is. If the WPA-PSK
complexity check feature is enabled, the key is not accepted unless it meets the
minimum criteria. See
