Option

Description

Select SSID

Sets the wireless network name.

SSID stands for Service Set

Identifier.

All stations must be configured with the correct SSID to

access the WLAN.

If the SSID does not match, that user will not be

granted access.

The naming conventions are: Minimum is one character and

maximum number of characters: 32 bytes.

Network

Authentication

It specifies the network authentication.

When this checkbox is

selected, it specifies that a network key be used for authentication to

the wireless network.

If the Network Authentication (Shared mode)

checkbox is not shared (that is, if open system authentication is

used), no authentication is provided.

Open system authentication

only performs identity verifications.

Different authentication type pops up different settings requests.

Choosing

802.1X

, enter RADIUS Server IP address, RADIUS Port,

and RADIUS key.

Also, enable WEP Encryption and the Encryption Strength.

Select the Current Network Key and enter 13 ASCII characters or 26

hexadecimal digits for 128-bit encryption keys and enter 5 ASCII

characters or 10 hexadecimal digits for 64-bit encryption keys.

Choosing

WPA

, you must enter WPA Group Rekey Interval.

Choosing

WPA-PSK

, you must enter WPA Pre-Shared Key and

Group Rekey Interval.

WEP

Encryption

It specifies that a network key is used to encrypt the data is sent over

the network.

When this checkbox is selected, it enables data

encryption and prompts the Encryption Strength drop-down menu.

Data Encryption (WEP Enabled) and Network Authentication use the

same key.

Encryption

strength

A session’s key strength is proportional to the number of binary bits

comprising the session key file.

This means that session keys with a

greater number of bits have a greater degree of security, and are

considerably more difficult to forcibly decode.

This drop-down

menu sets either a 64 8-bit (5-ASCII character or 10-hexadecimal

character) or 128 8-bit (13-ASCII character or 26-hexadecimal

character) key.

If you set a minimum 128-bit key strength, users attempting to

establish a secure communications channel with your server must

use a browser capable of communicating with a 128-bit session key.

The Encryption Strength settings do not display unless the network

Authentication (shared Mode) check box is selected.

7.3 MAC Filter

This MAC Filter page allows access to be restricted or allowed based on a MAC

address. All NICs have a unique 48-bit MAC address burned into the ROM chip on the

card.

When MAC address filtering is enabled, you are restricting the NICs that are

allowed to connect to your access point.

Therefore, an access point will grant

access to any computer that is using a NIC whose MAC address is on its “allows” list.

WiFi devices and access points that support MAC filtering let you specify a list of MAC

addresses that may connect to the access point, and thus dictate what devices are

authorized to access the wireless network.

When a device is using MAC filtering,

any address not explicitly defined will be denied access.

MAC Restrict mode:

Off

- disables MAC filtering;

Allow

–

permits

access

for the

specified MAC address;

deny

; reject access of the specified MAC address, then click

the

SET

button.

To delete an entry

,

select the entry at the bottom of the screen and then click the

Remove

button, located on the right hand side of the screen.

To add a MAC entry, click

Add

and enter MAC address

Allow: Permits PCs with listed MAC addresses to connect to access point.

Deny: Prevents PCs with listed MAC from connecting to the access point.

MAC

Address

Lists the MAC addresses subject to the Off, Allow, or Deny instruction.

The Add button prompts an entry field that requires you type in a MAC

address in a two-character, 6-byte convention: xx:xx:xx:xx:xx:xx where

xx are hexadecimal numbers.

The maximum number of MAC addresses

that can be added is 60.
