Open: No authentication is used. Shared The Pre-Shared

Key (PSK) authentication method is used.

In enterprises, WPA will be used in conjunction with both

wireless router and authentication server. In Small Office/ Home

Office (SOHO) environment, where there are no authentication

servers, user can use pre-shared key (PSK) mode in place of the

authentication server.

WPA: Wi-Fi® Protected Access (WPA) authentication

(802.1X) is used with an EAP type.

WPA consists of three main elements: an Authentication Server

(typically a RADIUS server), WPA-enabled router or AP (called

"Authenticator"), and a WPA-enabled client (called "Supplicant").

WPA-PSK: WPA authentication (802.1X) is used with a

Pre-Shared Key, which enables you to enter a static

Network key.

Data Encryption

Select the type of security encryption algorithm used. The

available types of encryption are based on the type of the

authentication selected.

Disabled: No encryption.
WEP: Deselect Network Key is provided for me

automatically and enter the Key provided by the network.

Available only with Open and Shared Authentication.

TKIP: Available with WPA and WPA-PSK Authentication.

TKIP (Temporal Key Integrity Protocol) includes four algorithms:

MIC (message integrity check), to protect packets from

tampering; PPK (Per-Packet Key) hashing, to prevent weak key

attacks; extended IV (initialization vector), to reduce IV reuse

and the possibility that a hacker will collect sufficient packets to

crack the encryption; and a re-keying mechanism, to change the

temporal key dynamically. TKIP is the most commonly used

encryption method; however, if your wireless clients do not

support TKIP, the WX-5803 also supports AES (Advanced

Encryption Security) encryption. AES will replace 802.11's

RC4-based encryption under 802.11i specification.

Network key

Enter the security key for data encryption, when WEP or

WPA-PSK is selected. This can be entered in ASCII or
