secret can be between 8 and 63 characters and can include special characters and spaces. For maximum
security, the "WPA Pre-Shared Key" should be a random sequence of either keyboard characters (upper and
lowercase letters, numbers, and punctuation) at least 20 characters long, or hexadecimal digits (numbers 0-9
and letters A-F) at least 24 hexadecimal digits long.
Note: The less obvious, longer and more 'random' your 'WPA Pre-Shared Key', the more secure your network.
Note the following 'WPA Encryption' options:
TKIP:
AES:
TKIP+AES:
WPA2
'WPA Pre-authentication' support in WPA2 allows a client to pre-authenticate with the NB9W toward which
it is moving, while maintaining a connection to the access point it's moving away from. This new capability
allows the roaming to occur in less than 1/10th of a second while a traditional roam without PMK caching
and pre-authentication would take more than one second. Time-sensitive applications like Citrix, video, or
VoIP will all break without fast roaming.
'Network Re-Auth Interval' is the interval specifi ed (seconds) that the wireless client needs to re-authenticate
with the NB9W.
For the remainder of the fi elds required, see above.
WPA2-PSK:
Mixed WPA2/WPA:
Mixed WPA2/WPA-PSK:

The Temporal Key Integrity Protocol (TKIP) takes over after the initial shared secret
is entered in your wireless devices and handles the encryption and automatic
rekeying.
WPA defi nes the use of Advanced Encryption Standard (AES) as an additional
replacement for WEP encryption. Because you may not be able to add AES support
through a fi rmware update to your existing wireless clients / equipment, support for
AES is optional and is dependent on vendor driver support.
This will allow either TKIP or AES wireless clients to connect to your NB9W.
Same as WPA-PSK, but you can only use AES with WPA2
and not WPA.
Enables WPA2 or WPA wireless clients to connect to the
NB9W. Requires a RADIUS server to authenticate the
wireless clients.
Enables WPA2 and WPA clients to authenticate using a PSK
(Pre-Shared Key) instead of a RADIUS server.
