•
Enable Auto Channel Scan
. The unit automatically finds the channel with least interference
and uses that channel. This is enabled by default. If you disable this feature, you can use the
Wireless Channel option to manually pick a channel.
•
Wireless Channel
. When Auto Channel Scan is disabled, use this option to manually pick a
channel.
•
Channel Width
. 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 WNHDE111 uses channel bonding technology to extend the
bandwidth for data transmission.
•
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.
•
Wireless Security Mode: WEP or WPA
. 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 unit placement.

Configuring WEP Wireless Security
WEP Shared Key authentication and WEP data encryption can be defeated by a determined
eavesdropper using publicly available tools.
1.
Select
Wireless Settings
under Setup in the main menu.
2.
In the Wireless Security Mode section, select
WEP
. The WEP options display.
3.
Select the encryption strength (64 or 128 bit data encryption).
4.
Enter the data encryption keys. These values must be identical on all computers and access
points in your network.

Configuring WPA Wireless Security
Wi-Fi Protected Access with Pre-Shared Key (WPA-PSK and WPA2-PSK) provides extremely
strong security, very effectively blocking eavesdropping. Both methods dynamically change the
encryption keys making them nearly impossible to circumvent. WPA2 adds support for hardware
based AES, which adds improved performance and the strongest data encryption.
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.
2.
Select one of the WPA-PSK or WPA2-PSK options for the security type. The WPA + WPA2
options the most flexible, since it allows clients using either one.
3.
In the
Passphrase
field, enter a word or group of 8–63 printable characters. The passphrase
is
case-sensitive.
4.
Click
Apply
to save your settings.
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.
1.
Log in to the unit.
2.
Select
Advanced Wireless
under Advanced in the main menu.
The available settings in this screen are:
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. Check whether newer drivers are available from the manufacturer.

Enable Wireless Router Radio
. If you disable the wireless router radio, wireless devices
cannot connect to the Wireless-N AccessPoint/Bridge. 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.
•
WPS Settings

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 4-10
.
The Wireless-N AccessPoint/Bridge provides two methods for connecting to a wireless client that
supports WPS, described in the following sections:
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.
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.

Push Button Configuration
There are two methods to enable a wireless client to join a network using a push button on the
router: using the physical push button or using the software button in the Add WPS Client screen.
Using the Physical Push Button
1.
Press the button on the Wireless-N AccessPoint/Bridge for over 5 seconds. For information
about the WPS button light, see the
.
The green
button light begins to blink in a regular pattern. While the light is blinking, you
have 2 minutes to enable WPS on the client that you are trying to connect to the router.
2.
On the wireless client, follow its specific networking instructions to enable WPS, to allow it to
connect to the router.
The Wireless-N AccessPoint/Bridge’s green
button light ceases blinking and remains on
when one of these conditions occurs:
•
The router and the client establish a wireless connection.
•
The 2-minute window period expires for establishing a WPS connection. If the connection
is not established, no WPS security settings will be specified in the Wireless-N
AccessPoint/Bridge.
Using the Software Button in the Add WPS Client Screen
1.
Log in to the router as described in
“Viewing or Changing Settings” on page 3-1
.
2.
Select
Add WPS Client
in the main menu, and click
Next.
3.
Select the
Push Button
setup method.

Click the
button in the Add WPS Client screen. The following screen displays:
The green
button light on the Wireless-N AccessPoint/Bridge begins to blink in a regular
pattern. While the button light is blinking, you have 2 minutes to enable WPS on the device
you are trying to connect to the router.
5.
In the wireless client, follow its specific networking instructions to enable WPS, to allow it to
connect to the router.
The Wireless-N AccessPoint/Bridge’s green
button light ceases blinking and remains on
when one of these conditions occurs:
•
The router and the client establish a wireless connection.
•
The 2-minute window period expires for establishing a WPS connection. If the connection
is not established, no WPS security settings will be specified in the Wireless-N
AccessPoint/Bridge.
Security PIN Entry
There are two ways to enable a wireless client to join a network using a PIN: using the unit’s
security PIN or using the wireless client’s security PIN.
Using the Unit’s Security PIN
1.
Obtain your unit’s security PIN from the rear panel of the router or from the Advanced
Wireless Settings screen.
2.
On the wireless client, follow its specific networking instructions to enter the router’s security
PIN and to establish a wireless connection with the router.
Using the Wireless Client’s Security PIN
1.
Log in to the WNHDE111.
