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 specified (seconds) that the wireless client needs to re-
authenticate with the NB9W.
For the remainder of the fields required, see above.
