Security Essentials - Free Antivirus for Windows. Ultra High Security Password Generator If some device was not following the WiFi Alliance WPA specification by not hashing the entire printable ASCII character set correctly, it would end up with a different 256-bit hash result than devices that correctly obeyed the specification.
It would then be unable to connect to any network that uses the full range of printable ASCII characters. Since we have heard unconfirmed anecdotal reports of such non-compliant WPA devices (and since you might have one), this page also offers "junior" WPA password strings using only the "easy" ASCII characters which even any non-fully-specification-compliant device would have to be able to properly handle. If you find that using the full random ASCII character set within your WPA-PSK protected WiFi network causes one of your devices to be unable to connect to your WPA protected access point, you can downgrade your WPA network to "easy ASCII" by using one of these easy keys.
And don't worry for a moment about using an easy ASCII key. Steganos LockNote.
