Chapter 6 Wireless LAN

P-974H/HW Series User’s Guide

6.3.2 Introduction to WPA(2)

Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. Key

differences between WPA(2) and WEP are user authentication and improved data

encryption.

6.3.2.1 User Authentication

WPA(2) applies IEEE 802.1x and Extensible Authentication Protocol (EAP) to

authenticate wireless clients using an external RADIUS database.

WEP

Encryption

WEP (Wired Equivalent Privacy) encrypts data frames before transmitting

over the wireless network.

Select Disable to allow all wireless stations to communicate with the

access points without any data encryption.

Select WEP (64-bit) or WEP (128-bit) to use data encryption.

Shared Key

Authentication

Select Required to use the selected WEP key for basic wireless

authentication.

Select Disabled to set the ZyXEL Device not to perform basic wireless

authentication with a WEP key.

Note: You can only configure 802.1x Authentication settings if

Shared Key Authentication is set to Disabled.

802.1x

Authentication

You must have a RADIUS server when you select this setting. You must

also configure the RADIUS Key field in this screen. The RADIUS server

must be set up with the same RADIUS Key as the ZyXEL Device.

Wireless clients authenticate with the RADIUS server before they can

access your wireless network.

Network Key

1.. 4

The WEP keys are used to encrypt data. Both the ZyXEL Device and the

wireless stations must use the same WEP key for data transmission.

If you want to manually set the WEP keys, enter the key in the field

provided.

If you chose 64-bit WEP, then enter any 5 ASCII characters or 10

hexadecimal characters ("0-9", "A-F").

If you chose 128-bit WEP, then enter 13 ASCII characters or 26

hexadecimal characters ("0-9", "A-F").

The values for the WEP keys must be set up exactly the same on all

wireless devices in the same wireless LAN.

You can configure all four keys, but only one key can be used at any one

time. The default key is Network Key 1.
