Encryption Strength Choices

Choose the encryption strength from the drop-down list. Please refer to

“Overview of WEP

Parameters” on page D-5

for a full explanation of each of these options, as defined by the IEEE

802.11 wireless communication standard.

•

Disable.

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

connection, but leaves your wireless data fully exposed.

•

64-bit or 128-bit WEP.

When 64-bit or 128-bit 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 PCs 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. These characters

are

case sensitive.

•

Manual

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

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

values

are not

case sensitive.

Before You Change the SSID and WEP Settings

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

your 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.

•

Network Name (SSID)

:

The Service Set Identification (SSID), called the wireless

network name in Windows XP, identifies the wireless network. You may use up to 32

alphanumeric characters. Record your customized SSID on the line below.

Name (SSID):

______________________________

Note:

The SSID in the wireless router is the SSID you configure in the wireless adapter

card. For the access point and wireless nodes to communicate with each other, all must be

configured with the same SSID.

•

Authentication.

The authentication setting, “Open System” or “Shared Key,” is unrelated

to encryption of transmissions. The two bands can use different authentication settings.

Choose “Shared Key” for more security, circle one: Open System or Shared Key

Note:

If you select shared key, the other devices in the network will not connect unless

they are set to Shared Key as well.

•

WEP Encryption Strength

. Choose the key size. Circle one:

64

or

128

bits.

•

WEP Encryption Keys

. The WGT624 v2 provides two methods for creating WEP

encryption keys:

–

Passphrase

. ______________________________

Enter a word or group of printable

characters. These characters

are

case sensitive. When you enter the Passphrase and

click the Generate button on the WGT624 v2, the keys will be generated.

–

Manual

. For 64-bit WEP, enter 10 hexadecimal digits (any combination of 0-9 or a-f).

These values

are not

case sensitive. For 128-bit WEP, enter 26 hexadecimal digits.

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

Key 1: ___________________________________

How to Set Up and Test Basic Wireless Connectivity

Follow the instructions below to set up and test basic wireless connectivity. Once you have

established basic wireless connectivity, you can enable security settings appropriate to your needs.

1.

Log in to the WGT624 v2 firewall at its default LAN address of

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 WGT624 v2 firewall.

Figure 4-4:

Wireless Settings menu

3.

Choose a suitable descriptive name for the wireless network name (SSID). In the SSID box,

enter a value of up to 32 alphanumeric characters. The default SSID is NETGEAR.

Note:

The SSID of any wireless access adapters must match the SSID you configure in the

108 Mbps Wireless Firewall Router WGT624 v2. If they do not match, you will not get a

wireless connection to the WGT624 v2.

4.

Set the Region. Select the region in which the wireless interface will operate.

5.

Set the Channel. The default channel is 11.

This field determines which operating frequency will be used. It should not be necessary to

change the wireless channel unless you notice interference problems with another nearby

wireless router or access point. Select a channel that is not being used by any other wireless

networks within several hundred feet of your firewall. For more information on the wireless

channel frequencies please refer to

“Wireless Channels” on page D-7

.

6.

For initial configuration and test, leave the Wireless Card Access List set to “Everyone” and

the Encryption Strength set to “Disabled.”

7.

Click Apply to save your changes.

8.

Configure and test your PCs for wireless connectivity.

Program the wireless adapter of your PCs to have the same SSID and channel that you

configured in the router. Check that they have a wireless link and are able to obtain an IP

address by DHCP from the firewall.

Once your PCs have basic wireless connectivity to the firewall, then you can configure the

advanced wireless security functions of the firewall.

How to Restrict Wireless Access by MAC Address

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

1.

Log in to the WGT624 v2 firewall at its default LAN address of

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 WGT624 v2 firewall.

Note:

If you are configuring the firewall from a wireless PC and you change the

firewall’s SSID, channel, or security settings, you will lose your wireless connection

when you click on Apply. You must then change the wireless settings of your PC to

match the firewall’s new settings.

Note:

When configuring the firewall from a wireless PC whose MAC address is not in

the Trusted PC list, if you select Turn Access Control On, you will lose your wireless

connection when you click on Apply. You must then access the wireless router from a

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

changes.
