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: ___________________________________
Key 2: ___________________________________
Key 3: ___________________________________
Key 4: ___________________________________
Use the procedures described in the following sections to configure the WGT624 v2. Store this

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.
