Table 2-4 WEP Authentication
FIELD DESCRIPTION
Transmit Key Enter the key number (1 to 4) in this field. Only one key can be enabled at any one
time. This key must be the same on the ZyAIR and the wireless stations to
communicate.
Key Type Select ASCII to enter the WEP keys as ASCII characters. Select this option if you
want to manually enter the WEP keys.
Select HEX to have the WEP keys as hexadecimal characters. Select this option if
you want the ZyAIR to automatically generate four different WEP keys based on the
passphrase specified in the Passphrase field.
Key 1 … 4 Enter the WEP keys in the fields provided.
If you select 64 Bits in the Encryption (WEP) field.
Enter either 10 hexadecimal digits in the range of “A-F”, “a-f” and “0-9” (e.g.
11AA22BB33) for hexadecimal key type
or
Enter 5 ASCII characters (case sensitive) ranging from “a-z”, “A-Z” and “0-
9” (e.g. MyKey) for
ASCII key type.
If you select
128 Bits in the Encryption (WEP) field,
Enter either 26 hexadecimal digits in the range of “A-F”, “a-f” and “0-9” (for
example, 00112233445566778899AABBCC) for hexadecimal key type
or
Enter 13 ASCII characters (case sensitive) ranging from “a-z”, “A-Z” and “0-
9” (for example, MyKey12345678) for
ASCII key type.
You must configure all four WEP keys the
first time you use the ZyAIR.
ASCII WEP keys are case sensitive.

2.10.2 Data Encryption with WPA
Select WPA from the Authentication drop-down list box to view the security configuration
options.
Introduction to WPA
Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i security specification draft. Key
differences between WPA and WEP are user authentication and improved data encryption.
User Authentication
WPA applies IEEE 802.1x and Extensible Authentication Protocol (EAP) to authenticate wireless
clients using an external RADIUS database. See later in this
User’s Guide for more information
on IEEE 802.1x and EAP.
WPA-PSK (WPA -Pre-Shared Key), only requires a single (identical) password entered into each
access point, wireless gateway and wireless client. As long as the passwords match, a client will
be granted access to a WLAN.
