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 also set to WPA-PSK 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 also set to WPA2-PSK and are configured with
the correct passphrase.
Use the procedures described in the following sections to specify the WNR2000 router. Store this
information in a safe place.
Changing Wireless Security Settings
This section describes the wireless settings that you can view and configure in the Wireless
Settings screen, which you access under Setup in the main menu.
Viewing Basic Wireless Settings
To specify the 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 Setup in the main menu. The Wireless Settings screen
displays
.
The available settings in this screen are:
•
Name (SSID)
. The SSID is also known as the wireless network name. Enter a value of up to
32 alphanumeric characters. When more than one wireless network is active, different wireless
network names provide a way to separate the traffic. For a wireless device to participate in a
particular wireless network, it must be configured with the SSID for that network. The
WNR2000 default SSID is
NETGEAR
. You can disable this broadcast as described in
“Viewing Advanced Wireless Settings” on page 2-12
.
•
Region
. This field identifies the region where the WNR2000 router can be used. It might not
be legal to operate the wireless features of the wireless router in a region other than one of
those identified in this field.
Figure 2-2
Note:
The region selection feature might not be available in all countries.

•
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
wireless network. The wireless router uses channel bonding technology to extend the
bandwidth for data transmission. For more information about the wireless channel
frequencies, see the online document that you can access from
“Wireless Networking Basics”
in Appendix B
.
•
Mode
. This field determines which data communications protocol is used. You can choose
from:
–
Up To 54 Mbps
. Legacy mode, for compatibility with the slower 802.11b and 802.11g
wireless devices.
–
Up To 145 Mbps
. Neighbor Friendly mode, for reduced interference with neighboring
wireless networks. Provides two transmission streams with different data on the same
channel at the same time, but also allows 802.11b and 802.11g wireless devices. This is
the default mode.
–
Up To 300 Mbps
. Performance mode, using channel expansion to achieve the 300 Mbps
data rate. The WNR2000 router will use the channel you selected as the primary channel
and expand to the secondary channel (primary channel +4 or –4) to achieve a 40 MHz
frame-by-frame bandwidth. The WNR2000 router will detect channel usage and will
disable frame-by-frame expansion if the expansion would result in interference with the
data transmission of other access points or clients.
•
Security Options
. The selection of wireless security options can significantly affect your
network performance. The time it takes to establish a wireless connection can vary depending
on both your security settings and router placement.
WEP connections can take slightly longer to establish. Also, WEP, WPA-PSK, and WPA2-
PSK encryption can consume more battery power on a notebook computer, and can cause
significant performance degradation with a slow computer. Instructions for configuring the
security options can be found in
“Choosing Appropriate Wireless Security” on page 2-1
. A full
explanation of wireless security standards is available in the online document that you can
access from
“Wireless Networking Basics” in Appendix B
.

Note:
The maximum wireless signal rate is derived from the IEEE Standard 802.11
specifications. Actual data throughput will vary. Network conditions and
environmental factors, including volume of network traffic, building materials
and construction, and network overhead, lower actual data throughput rate.

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
WNR2000 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
.
