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.
