must be identical on all computers and access points in your network. For 64-bit WEP,
enter 10 hexadecimal digits (any combination of 0–9 or A–F). For 128-bit WEP, enter
26 hexadecimal digits.
•
Select which of the four keys will be the default. Data transmissions are always encrypted
using the default key. The other keys can only be used to decrypt received data. The four
entries are disabled if WPA-PSK or WPA authentication is selected.

Configuring WPA or WPA2 Wireless Security
To configure WPA in the gateway:
1.
Log in to the gateway using its default address of
or at whatever IP address
the unit is currently configured. Use the default user name of
admin
and default password of
password
, or the password you have set up.
2.
In the main menu, under Setup, select
Wireless Settings
.
3.
Select either one of the WPA settings:
•
WPA-PSK
. This setting provides the TKIP encryption type and a pre-shared key
passphrase.
•
WPA
. This setting provides the TKIP encryption type with authentication from a
RADIUS server.
•
WPA2-PSK
. This setting provides the AES encryption type and a pre-shared key
passphrase.
Note:
If you use a wireless computer to configure WEP settings, you will be
disconnected when you click
Apply
. Reconfigure your wireless adapter to match
the new settings or access the gateway from a wired computer to make any further
changes.
Note:
Not all wireless adapters support WPA. Furthermore, client software is required on
the client. Windows XP and Windows 2000 with Service Pack 3 or above do
include the client software that supports WPA. The wireless adapter hardware and
driver must also support WPA. Consult the product documentation for your
wireless adapter and WPA client software for instructions on configuring WPA
settings.

Using Push 'N' Connect (WPS) to Configure Your Wireless
Network and Security
If your wireless clients support Wi-Fi Protected Setup (WPS), you can use this feature to configure
the gateway’s SSID and security settings and, at the same time, connect the wireless client securely
and easily to the gateway. Look for the
symbol on your client device (computers that will
connect wirelessly to the gateway are clients). WPS uses the network name (SSID) that is
specified in the Wireless Settings screen and sets the wireless security settings to either WPA-PSK
or WPA2-PSK and then and broadcasts these settings to the wireless client.
Some considerations regarding WPS are:
•
WPS supports only WPA-PSK and WPA2-PSK wireless security. WEP security is not
supported by WPS.
•
Before you can add a WPS client, the Security Option in the Wireless Settings screen must be
set to
Disabled
,
WPA-PSK
, or
WPA2-PSK
. See
“Manually Configuring Your Wireless
Settings and Security” on page 2-3
.
Note:
NETGEAR’s Push 'N' Connect feature 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.

A WPS client can be added using the Push Button method or the PIN method.
•
Using the Push Button
. This is the preferred method. See the following section,
“Using a
WPS Button to Add a WPS Client
.
•
Entering a PIN
. For information about using the PIN method, see
“Using a PIN Entry to Add
a WPS Client” on page 2-12
.
Using a WPS Button to Add a WPS Client
Any wireless computer or wireless adapter that will connect to the gateway wirelessly is a client.
The client must support a WPS PIN, and must have a WPS configuration utility, such as the
NETGEAR Smart Wizard or Atheros Jumpstart.
Before you can add a WPS client, the Security Option in the Wireless Settings screen must be set
to
Disabled
,
WPA-PSK
, or
WPA2-PSK
. See
“Manually Configuring Your Wireless Settings and
Security” on page 2-3
.
To use the gateway WPS button to add a WPS client:
1.
Log in to the gateway using its default address of
or at whatever IP address
the unit is currently configured.
2.
In the main menu, under Setup, select
WPS Settings
. The Wi-Fi Protected Setup (WPS)
screen displays.
By default, the
Push Button
radio button is selected.
3.
Click
Add
.
•
The Wireless LED on the front of the gateway begins to blink.
•
The gateway tries to communicate with the client for 2 minutes.
4.
Go to the client wireless computer, and run a WPS configuration utility. Follow the utility’s
instructions to click a WPS button.
