3.

Select the Turn Access Control On check box to enable restricting wireless computers by their

MAC addresses.

4.

If the wireless station is currently connected to the network, you can select it from the

Available Wireless Stations list. Click Add to add the station to the Trusted Wireless Stations

list.

5.

If the wireless station is not currently connected, you can enter its address manually. Enter the

MAC address of the authorized computer. The MAC address is usually printed on the wireless

card, or it may appear in the router’s DHCP table. The MAC address will be 12 hexadecimal

digits.

Click Add to add your entry. You can add several stations to the list, but the entries will be

discarded if you do not click Apply.

Note:

You can copy and paste the MAC addresses from the router’s Attached Devices menu

into the MAC Address box of this menu. To do this, configure each wireless computer to

obtain a wireless link to the router. The computer should then appear in the Attached Devices

menu.

Make sure the Turn Access Control On check box is selected, then click Apply.

Now, only devices on this list will be allowed to wirelessly connect to the DG834G. This prevents

unauthorized access to your network.

Choosing WEP Authentication and Security Encryption Methods

Figure 4-5.

Security Encryption section

Restricting wireless access prevents intruders from connecting to your network. However, the

wireless data transmissions are still vulnerable to snooping. Using the WEP data encryption

settings described below will prevent a determined intruder from eavesdropping on your wireless

data communications. Also, if you are using the Internet for such activities as purchases or

banking, those Internet sites use another level of highly secure encryption called SSL. You can tell

if a web site is using SSL because the web address begins with HTTPS rather than HTTP.

Authentication Type Selection

The DG834G lets you select the following wireless authentication schemes.

Note:

If you are configuring the router from a wireless computer whose MAC address is

not in the Trusted Wireless Stations list, and you select Trusted Wireless Stations only,

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

router from a wired computer to make any further changes.

Open System

•

Shared key

Set your wireless adapter according to the authentication scheme you choose for the DG834G

wireless router. Please refer to

“Authentication and WEP Data Encryption” on page D-2

for a full

explanation of each of these options, as defined by the IEEE 802.11g wireless communication

standard.

Encryption Choices

Please refer to

“Overview of WEP Parameters” on page D-5

for a full explanation of each of the

following choices, as defined by the IEEE 802.11g wireless communication standard. Choose the

encryption strength from the drop-down list:

Disable

No encryption will be applied. This setting is useful for troubleshooting your wireless connection,

but leaves your wireless data fully exposed.

64 or 128 bit WEP

When 64 Bit WEP or 128 Bit WEP is selected, WEP encryption will be applied.

If WEP is enabled, you can manually or automatically program the four data encryption keys.

These values must be identical on all computers and access points in your network.

There are two methods for creating WEP encryption keys:

•

Passphrase. Enter a word or group of printable characters in the Passphrase box and click the

Generate button.

•

Manual. 64-bit WEP: Enter 10 hexadecimal digits (any combination of 0-9, a-f, or A-F).

128-bit WEP: Enter 26 hexadecimal digits (any combination of 0-9, a-f, or A-F).

Select the radio button for the key you want to make active.

Note:

The authentication scheme is separate from the data encryption. You can choose

an authentication scheme which requires a shared key but still leave the data

transmissions unencrypted. If you require strong security, use both the Shared Key and

WEP encryption settings.

How to Configure WEP

To configure WEP data encryption, follow these steps:

1.

Log in to the DG834G firewall at its default LAN address of

http://192.168.0.1

with its default

user name of

admin

and default password of

password

, or using whatever LAN address and

password you have set up.

2.

Click the Wireless Settings link in the main menu of the DG834G router.

3.

Go to the Security Encryption portion of the page:

Figure 4-6.

4.

Select the Authentication Type.

5.

Select the Encryption setting.

6.

Enter the encryption keys. You can manually or automatically program the four data

encryption keys. These values must be identical on all computers and Access Points in your

network.

•

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 hexadecimal digits (any combination of 0-9, a-f, or A-F).

Select which of the four keys will be active.

7.

Select the radio button for the key you want to make active.

Be sure you clearly understand how the WEP key settings are configured in your wireless

adapter. Wireless adapter configuration utilities such as the one included in Windows XP only

allow entry of one key which must match the default key you set in the DG834G.

How to Configure WPA-PSK

Note

: Not all wireless adapters 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.

Consult the product document for your wireless adapter and WPA client software for instructions

on configuring WPA settings.

To configure WPA-PSK, follow these steps:

1.

Log in at the default LAN address of

http://192.168.0.1

, with the default user name of

admin

and default password of

password

, or using whatever LAN address and password you have

set up.

2.

Click

Wireless Settings

in the Setup section of the main menu of the DG834G.

3.

Choose the

WPA-PSK

radio button. The WPA-PSK menu will open.

4.

Enter the pre-shared key in the Passphrase field.

5.

Click

Apply

to save your settings.

Note:

When configuring the router from a wireless computer, if you configure WEP

settings, you will lose your wireless connection when you click Apply. You must then

either configure your wireless adapter to match the router WEP settings or access the

router from a wired computer to make any further changes.
