enabled (the selection is unchecked) the access point sends out WPA-PSK information for WiFi
handsets.
When you enable a wireless bridge, you can also see the other wireless bridges by SSID and
BSSID (MAC address).

Security
The
Wireless – Security
screen allows you to select the network authentication method and to
enable or disable WEP encryption.
Note
that depending on the network authentication that is selected, the screen will change
accordingly so additional fields can be configured for the specific authentication method.
Network authentication methods include the following—
•
Open
— anyone can access the network. The default is a disabled WEP encryption setting
•
Shared
— WEP encryption is enabled and encryption key strength of 64-bit or 128-bit
needs to be selected. Click on Set Encryption Keys to manually set the network encryption
keys. Up to 4 different keys can be set and you can come back to select which one to use
at anytime.

802.1X
— requires mutual authentication between a client station and the router by
including a RADIUS-based authentication server. Information about the RADIUS server
such as its IP address, port and key must be entered. WEP encryption is also enabled and
the encryption strength must also be selected.
•
WPA
(Wi-Fi Protected Access) — usually used for the larger Enterprise environment, it
uses a RADIUS server and TKIP (Temporal Key Integrity Protocol) encryption (instead of
WEP encryption which is disabled). TKIP uses128-bit dynamic session keys (per user, per
session, and per packet keys).
•
WPA-PSK
(Wi-Fi Protected Access – Pre-Shared Key) — WPA for home and SOHO
environments also using the same strong TKIP encryption, per-packet key construction,
and key management that WPA provides in the enterprise environment. The main

difference is that the password is entered manually. A group re-key interval time is also
required.
•
WPA2
(Wi-Fi Protected Access 2) — second generation WPA which uses AES (Advanced
Encryption Standard) instead of TKIP as its encryption method. Network re-authorization
interval is the time in which another key needs to be dynamically issued.

WPA2-PSK
(Wi-Fi Protected Access 2 – Pre-Shared Key) — suitable for home and SOHO
environments, it also uses AES encryption and requires you to enter a password and a re-
key interval time.
•
Mixed WPA2 / WPA
— useful during transitional times for upgrades in the enterprise
environment, this mixed authentication method allows “upgraded” and users not yet
“upgraded” to access the network via the router. RADIUS server information must be
entered for WPA and a as well as a group re-key interval time. Both TKIP and AES are
used.
