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.
