Configuring WEP Wireless Security
WEP Shared Key authentication and WEP data encryption can be defeated by a determined
eavesdropper using publicly available tools.
WEP offers the following options:
•
Automatic
. With the Automatic option, the router will try both Open System and Shared Key
authentication. Normally this setting is suitable. If it fails, select
Open System
or
Shared Key
.
You can also refer to your wireless adapter’s documentation to see what method to use.
•
Open System
. With Open System authentication and 64 or 128 bit WEP data encryption, the
WNR2000v2 router
does
perform data encryption but
does not
perform any authentication.
Anyone can join the network. This setting provides very little practical wireless security.
•
Shared Key
. With Shared Key authentication, a wireless device must know the WEP key to
join the network. Select 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
field.
Manually entered keys
are not
case-sensitive, but passphrase characters
are
case-sensitive.
To configure WEP data encryption:
1.
Select
Wireless Settings
under Setup in the main menu.
2.
In the Security Options section, select
WEP
. The WEP options display.
Note:
If you use a wireless computer to configure WEP settings, you will be disconnected
when you click
Apply
. You must then either configure your wireless adapter to
match the wireless router WEP settings or access the wireless router from a wired
computer to make any further changes. Not all wireless adapter configuration
utilities support passphrase key generation.

.
3.
Select the authentication type and encryption strength.
4.
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
. In the
Passphrase
field, enter a word or group of printable characters, and
click
Generate
. The passphrase is case-sensitive. For example, NETGEAR is not the
same as nETgear. The four key fields are automatically populated with key values.
•
Manual
. Enter 10 hexadecimal digits (any combination of 0–9, a–f, or A–F). These
entries are not case-sensitive. For example, AA is the same as aa.
Select which of the four keys to activate.

Configuring WPA-PSK and WPA2-PSK Wireless Security
Wi-Fi Protected Access with Pre-Shared Key (WPA-PSK and WPA2-PSK) data encryption
provides extremely strong data security, very effectively blocking eavesdropping. Because WPA
and WPA2 are relatively new standards, older wireless adapters and devices might not support
them. Check whether newer drivers are available from the manufacturer. Also, you might be able
to use the Push 'N' Connect feature to configure this type of security if it is supported by your
wireless clients. See
“Using Push 'N' Connect (Wi-Fi Protected Setup)” on page 2-13
.

WPA–Pre-Shared Key
does
perform authentication. WPA-PSK uses TKIP (Temporal Key
Integrity Protocol) data encryption, and WPA2-PSK uses AES (Advanced Encryption Standard)
data encryption. Both methods dynamically change the encryption keys making them nearly
impossible to circumvent.
Mixed mode allows clients using either WPA-PSK (TKIP) or WPA2-PSK (AES). This provides
the most reliable security, and is easiest to implement, but it might not be compatible with older
adapters.
To configure WPA-PSK, WPA2-PSK, or WPA-PSK+WPA2-PSK:
1.
Select
Wireless Settings
under Setup in the main menu. The Wireless Settings screen
displays.
2.
Select one of the WPA-PSK or WPA2-PSK options for the security type. The third option
(WPA-PSK [TKIP] + WP2-PSK [AES]) is the most flexible, since it allows clients using
either WPA-PSK or WPA2-PSK.
3.
In the
Passphrase
field, enter a word or group of 8–63 printable characters. The passphrase is
case-sensitive.
Note:
Not all wireless adapters support WPA. Furthermore, client software is also
required. Windows XP with Service Pack 2 does include WPA support.
Nevertheless, the wireless adapter hardware and driver must also support WPA.
For instructions on configuring wireless computers or PDAs (personal digital
assistants) for WPA-PSK security, consult the documentation for the product you
are using.

Viewing Advanced Wireless Settings
This section describes the wireless settings that you can view and specify in the Advanced
Wireless Settings screen, which you access under Advanced in the main menu.
To configure the advanced wireless security settings of your router:
1.
Log in to the router as described in
“Logging In To Your Wireless Router” on page 1-2
.
2.
Select
Wireless Settings
under Advanced in the main menu. The advanced Wireless Settings
screen displays
The available settings in this screen are:
•
Enable Wireless Router Radio
. If you disable the wireless router radio, wireless devices
cannot connect to the WNR2000v2 router. If you will not be using your wireless network
for a period of time, you can clear this check box and disable all wireless connectivity.
•
Enable SSID Broadcast
. Clear this check box to disable broadcast of the SSID, so that
only devices that know the correct SSID can connect. Disabling SSID broadcast nullifies
the wireless network discovery feature of some products such as Windows XP.

•
Enable WMM
. Clear this check box to disable WMM. WMM (Wireless Multimedia), a
subset of the 802.11e standard, allows wireless traffic to have a range of priorities,
depending on the kind of data. Time-dependent information, like video or audio, will have
a higher priority than normal traffic. For WMM to function correctly, Wireless clients
must also support WMM.
•
Fragmentation Threshold
,
CTS/RTS Threshold
, and
Preamble Mode
. The
Fragmentation Threshold, CTS/RTS Threshold, and Preamble Mode options are reserved
for wireless testing and advanced configuration only. Do not change these settings.
•
WPS Settings
. For information about these settings, see the section,
“Using Push 'N'
Connect (Wi-Fi Protected Setup)” on page 2-13
.
•
Wireless Card Access List
. For information about this list, see
“Restricting Wireless
Access by MAC Address” on page 2-19

Using Push 'N' Connect (Wi-Fi Protected Setup)
If your wireless clients support Wi-Fi Protected Setup (WPS), you can use this feature to configure
the router’s network name (SSID) and security settings and, at the same time, connect a wireless
client securely and easily to the router. Look for the
symbol on your client device. WPS
automatically configures the network name (SSID) and wireless security settings for the router (if
the router is in its default state) and broadcasts these settings to the wireless client.
When you add wireless clients, whether or not they are WPS enabled, the added devices must
share the same network name (SSID) and security passphrase. For more information, see
“Connecting Additional Wireless Client Devices after WPS Setup” on page 2-18
.
The WNR2000v2 router provides two methods for connecting to a wireless client that supports
WPS, described in the following sections:
Note:
NETGEAR’s Push 'N' Connect feature is based on the Wi-Fi Protected Setup
(WPS) standard (for more information, see
). All other Wi-Fi-
certified and WPS-capable products should be compatible with NETGEAR
products that implement Push 'N' Connect.
Note:
If you choose to use WPS, the only security methods supported are WPA-PSK and
WPA2-PSK. WEP security is not supported by WPS.
