2.4.3 Security

This Access Point provides complete wireless LAN security functions, include WEP,

IEEE 802.11x, IEEE 802.11x with WEP, WPA with pre-shared key and WPA with

RADIUS. With these security functions, you can prevent your wireless LAN from illegal

access. Please make sure your wireless stations use the same security function.

2.4.3.1 WEP only

When you select 64-bit or128-bit WEP key, you have to enter WEP keys to encrypt data.

You can generate the key by yourself and enter it. You can enter four WEP keys and

select one of them as default key. Then the router can receive any packets encrypted by

one of the four keys

Parameters

Default

Description

Key Length

64-bit

You can select the WEP key length for

encryption, 64-bit or 128-bit. Larger WEP key

length will provide higher level of security, but

the throughput will be lower.

47

Key Format

You may select to select ASCII Characters

(alphanumeric format) or Hexadecimal Digits (in

the "A-F", "a-f" and "0-9" range) to be the WEP

Key.

For example:

ASCII Characters: guest

Hexadecimal Digits: 12345abcde

Default Key

Select one of the four keys to encrypt your data.

Only the key you select it in the "Default key" will

take effect.

Key 1 - Key 4

The WEP keys are used to encrypt data

transmitted in the wireless network. Fill the text

box by following the rules below.

64-bit WEP: input 10-digit Hex values (in the "A-

F", "a-f" and "0-9" range) or 5-digit ASCII

character as the encryption keys.

128-bit WEP: input 26-digit Hex values (in the

"A-F", "a-f" and "0-9" range) or 13-digit ASCII

characters as the encryption keys.

configure other advance sections or start using the router (with the advance settings in place)

2.4.3.2 802.1x only

IEEE 802.1x is an authentication protocol. Every user must use a valid account to login

to this Access Point before accessing the wireless LAN. The authentication is processed

by a RADIUS server. This mode only authenticates user by IEEE 802.1x, but it does not

encryption the data during communication.

48

Parameters

Default

Description

RADIUS Server IP address

The IP address of external RADIUS server.

RADIUS Server Port

The service port of the external RADIUS server.

RADIUS Server Password

The password used by external RADIUS server.

2.4.3.3 802.1x WEP Static key

IEEE 802.1x is an authentication protocol. Every user must use a valid account to login

to this Access Point before accessing the wireless LAN. The authentication is processed

by a RADIUS server. This mode also uses WEP to encrypt the data during

communication.

49

For the WEP settings, please refer to section 2.4.3.1

2.4.3.4 WPA Pre-shared key

Wi-Fi Protected Access (WPA) is an advanced security standard. You can use a pre-

shared key to authenticate wireless stations and encrypt data during communication. It

uses TKIP or CCMP(AES) to change the encryption key frequently. So the encryption

key is not easy to be broken by hackers. This can improve security very much.

50

Parameters

Default

Description

WPA(TKIP)

TKIP can change the encryption key frequently

to enhance the wireless LAN security.

WPA2(AES)

This use CCMP protocol to change encryption

key frequently. AES can provide high level

encryption to enhance the wireless LAN security.

WPA2 Mixed

This will use TKIP or AES based on the other

communication peer automatically.

Pre-shared Key Format

You may select to select Passphrase

(alphanumeric format) or Hexadecimal Digits (in

the

“

A-F

”

,

“

a-f

”

and

“

0-9

”

range) to be the Pre-

shared Key. For example:

Passphrase: iamguest

Hexadecimal Digits: 12345abcde

Pre-shared Key

The Pre-shared key is used to authenticate and

encrypt data transmitted in the wireless network.

Fill the text box by following the rules below.

Hex WEP: input 64-digit Hex values (in the

“

A-F

”

,

“

a-f

”

and

“

0-9

”

range) or at least 8 character pass

phrase as the pre-shared keys.
