Understanding Wireless Security Options

The table below identifies the various basic wireless security options. A full explanation of these

standards is available in

Appendix B, “Wireless Networking Basics”

.

Table 3-1.

Basic Wireless Security Options

Field

Description

Off

No wireless security.

WEP

WEP offers the following options:

•

Open System

With Open Network Authentication and 64- or 128-bit WEP Data Encryption, the

WG602 v2

does

perform 64- or 128-bit data encryption but

does not

perform any

authentication.

•

Shared Key

Shared Key authentication encrypts the SSID and data.

Choose the Encryption Strength (64- or 128-bit data encryption). Manually enter

the key values or enter a word or group of printable characters in the Passphrase

box. Manually entered keys

are

case sensitive but passphrase characters

are not

case sensitive.

Note

: Not all wireless adapter configuration utilities support passphrase key

generation.

• Auto

WPA-PSK

WPA-Pre-shared Key

does

perform authentication, uses 128-bit data encryption

and dynamically changes the encryption keys making it nearly impossible to

circumvent.

Enter a word or group of printable characters in the Password Phrase box. These

characters

are

case sensitive.

Note

: Not all wireless adapter configuration utilities support WPA. Furthermore,

client software is required on the client. Windows XP and Windows 2000 with

Service Pack 3 do include the client software that supports WPA. Nevertheless, the

wireless adapter hardware and driver must also support WPA.

Information to Gather Before Changing Basic Wireless Settings

Before customizing your wireless settings, print this form and record the following information. If

you are working with an existing wireless network, the person who set up or is responsible for the

network will be able to provide this information. Otherwise, you will choose the settings for your

wireless network. Either way, record the settings for your wireless network in the spaces below.

•

Wireless Network Name (SSID)

:

______________________________

The SSID, identifies

the wireless network. You can use up to 32 alphanumeric characters. The SSID is case

sensitive. The SSID in the wireless adapter card must match the SSID of the wireless access

point. In some configuration utilities (such as in Windows XP), the term “wireless network

name” is used instead of SSID.

•

If WEP Authentication is Used.

Circle one:

Open System

,

Shared Key, or Auto

.

Note:

If you select Shared Key, the other devices in the network will not connect unless they

are set to Shared Key as well and are configured with the correct key.

–

WEP Encryption key size

. Choose one:

64-bit

or

128-bit

. Again, the encryption key size

must be the same for the wireless adapters and the wireless access point.

–

Data Encryption (WEP) Keys

. There are two methods for creating WEP data encryption

keys. Whichever method you use, record the key values in the spaces below.

•

Passphrase method

. ______________________________

These characters

are

case

sensitive. Enter a word or group of printable characters and click the Generate Keys

button. Not all wireless devices support the passphrase method.

•

Manual method

. These values

are not

case sensitive. For 64-bit WEP, enter 10 hex

digits (any combination of 0-9 or a-f). For 128-bit WEP, enter 26 hex digits.

Key 1: ___________________________________

Key 2: ___________________________________

Key 3: ___________________________________

Key 4: ___________________________________

•

If WPA-PSK Authentication is Used.

–

Passphrase

: ______________________________

These characters

are

case sensitive.

Enter a word or group of printable characters. When you use WPA-PSK, the other devices

in the network will not connect unless they are set to WPA-PSK as well and are configured

with the correct Passphrase.

Use the procedures described in the following sections to configure the WG602 v2. Store this

information in a safe place.

How to Configure WEP Wireless Security

To configure WEP data encryption, follow these steps:

1.

Click the Security Settings link in the Setup section of the main menu and select WEP for the

Security Type.

Figure 3-10: WEP Settings page

2.

The Authentication Type is set to Any by default. Change the Authentication Type to Shared

Key to use WEP data encryption.

3.

For the Encryption Strength, select 64- or 128-bit encryption.

4.

You can manually or automatically program the four data encryption keys. These values must

be identical on all PCs and access points in your network.

Note:

If you use a wireless PC to configure WEP settings, you will be disconnected

when you click Apply. Reconfigure your wireless adapter to match the new settings or

access the wireless access point from a wired PC to make any further changes.

•

Automatic — enter a word or group of printable characters in the Passphrase box and click

the Generate button. The four key boxes will be automatically populated with key values.

•

Manual — enter ten hexadecimal digits (any combination of 0-9, a-f, or A-F)

Select which of the four keys will be active.

See

“WEP Wireless Security” on page B-4

for a full explanation of each of these options, as

defined by the IEEE 802.11 wireless communication standard.

How to Configure WPA-PSK Wireless Security

Note

: Not all wireless adapters support WPA. Furthermore, client software is also required.

Windows XP and Windows 2000 with service pack 3 do include WPA support. Nevertheless, the

wireless adapter hardware and driver must also support WPA. For instructions on configuring

wireless PCs or PDAs for WPA-PSK security, consult the documentation for the product you are

using.

To configure WPA-PSK, follow these steps:

1.

Click the Security Settings link in the Setup section of the main menu and select WPA-PSK for

the Security Type.

Figure 3-11: WPA Settings menu

2.

Enter a word or group of 8-63 printable characters in the Password Phrase box.

3.

Click Apply to save your settings.

How to Restrict Wireless Access by MAC Address

The Access Control page lets you block or allow the network access privilege of the specified

stations through the 54 Mbps Wireless Access Point WG602 v2. This provides an additional layer

of security.

Figure 3-12: Access Control options

To restrict access based on MAC Addresses, follow these steps:

1.

From the Setup section of the main menu, click Access Control to display the Wireless Access

page shown below.

2.

Select the type of Access Control:

Note:

If you use a wireless PC to configure WPA settings, you will be disconnected

when you click Apply. Reconfigure your wireless adapter to match the new settings or

access the wireless access point from a wired PC to make any further changes.

Note:

When configuring the WG602 v2 from a wireless PC whose MAC address is not

in the access control list, if you select Turn Access Control On, you will lose your

wireless connection when you click Apply. You must then access the wireless access

point from a wired PC or from a wireless PC which is on the access control list to make

any further changes.
