in the wireless network. There are two types of key length: 64-bit and

128-bit. Assign a default encryption key (Key#1 to Key#4) by clicking

on the corresponding radio button. To fill in each text field:

• 64-bit: Input 10-digit hex values (in the A-F, a-f and 0-9 range) or

5-digit ASCII characters (a-z and 0-9) as the encryption keys.

For example: “0123456aef“ or “test1.”

• 128-bit: Input 26-digit hex values (in the A-F, a-f and 0-9 range) or

13-digit ASCII characters (“a-z” and “0-9”) as the encryption keys.

For example: “01234567890123456789abcdef“ or “administrator.”
The IEEE 802.1X specification describes a protocol that can be used for

authenticating both clients (802.1x Setting/Certification below) and servers

(802.1x Setting/CA Server below) on a network. The authentication

algorithms and methods are those provided by the Extensible Authentication

Protocol (EAP), a method of authentication that has been in use for a

number of years on networks that provide Point-to-Point Protocol (PPP)

support (as many Internet service providers and enterprises do). EAP

runs before network layer protocols transmit data over the link.
When an AP acting as an authenticator detects a wireless station on the

LAN, it sends an EAP request for the user’s identity to the device. In

turn, the device responds with its identity, and the AP relays this identity

to an authentication server (typically an external RADIUS server).
