NB9/NB9W ADSL2+ VoIP Router 35

YML790 Rev8

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.

WPA2-PSK: Same as WPA-PSK, but you can only use AES with WPA2

and not WPA.

Mixed WPA2/WPA: Enables WPA2 or WPA wireless clients to connect to the

NB9W. Requires a RADIUS server to authenticate the

wireless clients.

Mixed WPA2/WPA-PSK: Enables WPA2 and WPA clients to authenticate using a PSK

(Pre-Shared Key) instead of a RADIUS server.
