WPA

or

WPA1/WPA2

: Defines a transitional mode of operation for networks

moving from WPA security to WPA2. WPA1/WPA2 Enterprise Mode allows both

WPA1 and WPA2 clients to associate to a common SSID interface. In WPA1/

WPA2 mixed mode, the unicast encryption cipher (TKIP or AES-CCMP) is

negotiated for each client. The access point advertises its supported encryption

ciphers in beacon frames and probe responses. WPA1 and WPA2 clients select

the cipher they support and return the choice in the association request to the

access point. For mixed-mode operation, the cipher used for broadcast frames

is always TKIP. WEP encryption is not allowed.

-

802.1x

: IEEE 802.1X is a standard framework for network access control that

uses a central RADIUS server for user authentication. This control feature

prevents unauthorized access to the network by requiring an 802.1X client

application to submit user credentials for authentication. The 802.1X standard

uses the Extensible Authentication Protocol (EAP) to pass user credentials

(either digital certificates, user names and passwords, or other) from the client

to the RADIUS server. Client authentication is then verified on the RADIUS

server before the access point grants client access to the network.

Encryption Type

– Selects the data encryption type to use. (Default: determined

by the Security Mode selected)

-

None

: Disables data encryption.

-

WEP

: Selects WEP keys for data encryption.

-

TKIP

: Uses Temporal Key Integrity Protocol (TKIP) keys for encryption. WPA

specifies TKIP as the data encryption method to replace WEP. TKIP avoids the

problems of WEP static keys by dynamically changing data encryption keys.

-

AES

: Uses Advanced Encryption Standard (AES) keys for encryption. WPA2

uses AES Counter-Mode encryption with Cipher Block Chaining Message

Authentication Code (CBC-MAC) for message integrity. The AES

Counter-Mode/CBCMAC Protocol (AES-CCMP) provides extremely robust data

confidentiality using a 128-bit key. Use of AES-CCMP encryption is specified as

a standard requirement for WPA2. Before implementing WPA2 in the network,

be sure client devices are upgraded to WPA2-compliant hardware.

-

TKIP/AES

: Uses either TKIP or AES keys for encryption. WPA/WPA2 mixed

modes allow both WPA and WPA2 clients to associate to a common SSID

interface. In mixed mode, the unicast encryption cipher (TKIP or AES-CCMP) is

negotiated for each client.

•

Default Key ID

– Sets the WEP key used

for authentication.

(Default: 1; Range: 1~4)

Key 1 ~ Key 4

– Sets WEP key values.

The user must first choose between ASCII

or Hexadecimal keys. At least one key

must be specified. Each WEP key has an

index number. The selected key is used

for authentication and encryption on the

VAP interface. Enter key values that

match the key type and length settings.

Standard keys are either 5 or 13

alphanumeric characters; or 10 or 26

hexadecimal digits. (Default: ASCII, no prese

t value)

RADIUS

Remote Authentication Dial-in User Service (RADIUS) is an authentication protocol

that uses software running on a central server to control access to RADIUS-aware

devices on the network. An authentication server contains a database of user

credentials for each user that requires access to the network.

A RADIUS server must be specified for the access point to implement IEEE 802.1X

network access control and Wi-Fi Protected Access (WPA) wireless security.

Click “WLAN1/WLAN2 Security” and be sure that an ‘Enterprise” mode is selected.

Note:

This guide assumes that you have already configured RADIUS server(s) to

support the access point. Configuration of RADIUS server software is beyond the

scope of this guide, refer to the documentation provided with the RADIUS server

software.

RADIUS Setting

— Configures RADIUS server settings.

Note:

RADIUS settings only apply to WPA, WPA2, or WPA/WPA2 Enterprise

modes.

•

RADIUS Server IP Address

– Specifies the IP address of the RADIUS server.

•

RADIUS Server Port

– The User Datagram Protocol (UDP) port number used by

the RADIUS server for authentication messages. (Range: 1024-65535;

Default: 1812)

RADIUS Server Shared Secret

– A shared text string used to encrypt messages

between the access point and the RADIUS server. Be sure that the same text string

is specified on the RADIUS server. Do not use blank spaces in the string.

(Maximum length: 20 characters)

•

RADIUS Server Session Timeout

– Number of seconds the access point waits

for a reply from the RADIUS server before resending a request. (Range: 1-60

seconds; Default: 0)

Wi-Fi Protected Setup (WPS)

Wi-Fi Protected Setup (WPS) is designed to ease installation and activation of

security features in wireless networks. WPS has two basic modes of operation,

Push-button Configuration (PBC) and Personal Identification Number (PIN). The

WPS PIN setup is optional to the PBC setup and provides more security. The WPS

button on the wireless AP/Router can be pressed at any time to allow a single device

to easily join the network.

Note:

WPS settings only apply to WLAN1.

The WPS Settings page includes configuration options for setting WPS device PIN

codes and activating the virtual WPS button.

Click on “Wireless Settings,” followed by ‘WPS”.

WPS Function

— Enables WPS, locks security settings, and refreshes WPS

configuration information.

•

WPS

– Enables WPS. (Default: Disable)

WPS Summary

– Provides detailed WPS statistical information.

•

WPS Current Status

– Displays if there is currently any WPS traffic connecting to

the wireless AP/Router. (Options: Start WSC Process; Idle; Default: Idle)

•

WPS Configured

– States if WPS for wireless clients has been configured for this

device. (Default: no)

•

WPS SSID

– The service set identifier for WLAN1. (Default: SMC)

•

WPS Auth Mode

– The method of authentication used. (Default: Open)

•

WPS Encryp Type

– The encryption type used for WLAN1. (Default: None)

•

WPS Default Key Index

– Displays the WEP default key (1~4).

•

WPS Key (ASCII)

– Displays the WPS security key (ASCII) which can be used to

ensure the security of the wireless network.

•

AP PIN

– Displays the PIN Code for the wireless AP/Router. The default is

exclusive for each unit. (Default: 61461345)

WPS Configuration

— Configures WPS settings for the wireless AP/Router.

•

WPS Mode

– Selects between methods of broadcasting the WPS beacon to

network clients wanting to join the network:

-

: The wireless AP/Router, along with other WPS devices, such as notebook

PCs, cameras, or phones, all come with their own eight-digit PIN code. When

one device, the WPS enrollee, sends a PIN code to the wireless AP/Router, it

becomes the WPS registrar. After configuring PIN-Code information you must

press “Apply” to send the beacon, after which you have up to two minutes to

activate WPS on devices that need to join the network.

-

PBC

: This has the same effect as pressing the physical WPS button that is

located on the front of the wireless AP/Router. After checking this option and

clicking “Apply” you have up to two minutes to activate WPS on devices that

need to join the network.
