•
WPA-PSK
and
WPA2-PSK.
Wi-Fi Protected Access, Pre-Shared Key (WPA-PSK and
WPA2-PSK) data encryption provide strong data security. WPA-PSK and WPA2-PSK block
eavesdropping. Because these are new standards, wireless device driver and software
availability may be limited.
•
Turn Off the Wireless LAN.
If you disable the wireless LAN, wireless devices cannot
communicate with the router at all. You might choose to turn off the wireless LAN when you
are away and other users of your network all use wired connections.
Understanding Wireless Settings
To configure the Wireless settings of your firewall, click the
Wireless
link in the main menu of the
browser interface. The Wireless Settings menu appears, as shown below.

•
Name (SSID).
The SSID is also known as the wireless network name. Enter a value of up to
32 alphanumeric characters. In a setting where there is more than one wireless network,
different wireless network names provide a means for separating the traffic. Any device you
want to participate in a particular wireless network will need to use this SSID for that network.
The WPNT834 default SSID is:
NETGEAR
.
•
Region.
This field identifies the region where the WPNT834 can be used. It may not be legal
to operate the wireless features of the wireless router in a region other than one of those
identified in this field.
•
Channel.
This field determines which operating frequency is used. It should not be necessary
to change the wireless channel unless you notice interference problems with another nearby
access point. For more information on the wireless channel frequencies, see
“Wireless
Communications” in Appendix B
.
•
Mode.
This field determines which data communications protocol is used. You can select “g
only”, “b only”, “g and b”, “Up To 126 Mbps”, and “Up To 240 MBps”. The “g only” option
dedicates the WPNT834 to communicating with the higher bandwidth 802.11g wireless
devices exclusively. “b only” dedicates the WPNT834 to communicating with the higher
bandwidth 802.11b wireless devices exclusively. The “g and b” mode provides backward
compatibility with the slower 802.11b wireless devices while still enabling 802.11g
communications.
•
Security Options.
These options are the wireless security features you can enable. The table
below identifies the various basic wireless security options. A full explanation of these
standards is available in
“Wireless Communications” in Appendix B
.
Note:
The region selection feature may not be available in all countries.

WEP
WEP offers the following options:
•
Open System
With Open Network Authentication and 64- or 128-bit WEP Data Encryption, the WPNT834
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
The wireless router automatically detects whether Open System or Shared Key is used.
WPA-PSK
WPA2-PSK
WPA-Pre-shared Key
does
perform authentication. WPA2-PSK uses TKIP (Temporal Key
Integrity Protocol) data encryption and WPA2-PSK uses AES (Advanced Encryption Standard)
data encryption. Both dynamically change the encryption keys making them 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 Service Pack 2 and Windows XP Service Pack 1 with
WPA patch do include the client software that supports WPA. Nevertheless, the wireless
adapter hardware and driver must also support WPA.

Wireless Configuration
v1.0, November 2005
To configure the advanced wireless settings of your firewall, click the
Wireless Setup
link in the
Advanced section of the main menu of the browser interface. The Advanced Wireless Settings
menu appears, as shown below.
•
Enable Wireless Router Radio.
If you disable the wireless router radio, wireless devices
cannot connect to the WPNT834.
•
Enable SSID Broadcast.
If you disable broadcast of the SSID, only devices that have the
correct SSID can connect. Disabling SSID broadcast nullifies the wireless network ‘discovery’
feature of some products such as Windows XP.
•
Wireless Card Access List.
When the Trusted PCs Only radio button is selected, the
WPNT834 checks the MAC address of the wireless station and only allows connections to
computers identified on the trusted computers list.
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 must choose the settings for your
wireless network. Either way, record the settings for your wireless network in the spaces below.
Figure 4-3
Note:
The
Fragmentation Threshold
,
CTS/RTS Threshold
, and
Preamble Mode
options are reserved for wireless testing and advanced configuration only. Do not
change these settings.

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 router. 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
.
–
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 router.
–
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 or WPA2-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. Similarly, when you use WPA2-PSK, the other devices in the
network will not connect unless they are aslo set to WPA2-PSK and are configured with
the correct Passphrase.
Use the procedures described in the following sections to configure the WPNT834. Store this
information in a safe place.
Note:
If you select
Shared Key
, the other devices in the network will not connect
unless they are also set to Shared Key and are configured with the correct key.
