Wireless NetworkName (SSID)The SSID is also known as the wireless network name. 
Enter a 32-character (maximum) name in this field. The 
characters are case sensitive. 
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 wireless network must use the SSID.
Control ChannelThe wireless channel used by the gateway. The default is 
channel 11.
You should not need to change the wireless channel 
unless you experience interference (shown by lost 
connections and/or slow data transfers). Should this 
happen, you might need to try different channels to see 
which is the best. 
802.11 ModeSelect the desired wireless mode. The options are: 
•Auto
•b & g only. Only 802.11g and 802.11b wireless stations 
can be used. 
•g only. Only 802.11g wireless stations can be used. 
•b only. Only 802.11b wireless stations can be used. 
Wireless Access 
PointEnable Wireless Access 
PointOn by default, you can also turn off the wireless radio to 
disable access through this device. This can be helpful 
for configuration, network tuning, or troubleshooting 
activities.
Allow Broadcast Name 
(SSID)On by default, the gateway broadcasts its SSID, allowing 
wireless stations which have a “null” (blank) SSID to 
adopt the correct SSID. The default SSID is NETGEAR.
If you disable broadcast of the SSID, only devices that 
have the correct SSID can connect. This nullifies the 
wireless network “discovery” feature of some products 
such as Windows XP, but the data is still fully exposed to 
a determined snoop using specialized test equipment 
like wireless sniffers. For this reason NETGEAR 
recommends that you also enable wireless security.

Wi-Fi Protected 
Setup (WPS)WPS ConfigTo use WPS, you must enable WPS Config and click 
Apply.
Device NameThe default is NetgearAP. This identifies your gateway 
for client WPS devices that want to join the network.
STA PINThe PIN is displayed so that you can use it to configure 
the gateway through WPS (Wi-Fi Protected Setup). It is 
also displayed on the gateway’s label.
WPS MethodPIN or Push Button can be used.
Start WPSIf WPS Config is enabled, clicking Start WPS causes the 
gateway to try to associate with a client. If security is set 
to Disable, it is automatically set to WPA-PSK. For more 
information about WPS, see 
“Using Push N Connect 
(WPS) to Configure Your Wireless Network and Security” 
on page 2-9.
Security OptionsDisableWireless security is disabled by default. After the 
gateway is connected to the Internet, NETGEAR strongly 
recommends that you implement wireless security.
Security Options 
(continued)• WEP (Wired Equivalent 
Privacy) 64-bit encryption
• WEP (Wired Equivalent 
Privacy) 128-bit encryption
WEP security uses encryption keys to provides data 
security. You can select 64-bit or 128-bit encryption. See 
“Configuring WEP (Wired Equivalent Privacy) Wireless 
Security” on page 2-7.
• WPA-PSK (Wi-Fi 
Protected Access Pre-
Shared Key)
•WPA
• WPA2-PSK (Wi-Fi 
Protected Access 2 Pre-
Shared Key)
•WPA2
Wi-Fi Protected Access (WPA) data encryption provides 
data security. The very strong authentication along with 
dynamic per frame rekeying of WPA make it virtually 
impossible to compromise. 
• WPA uses the TKIP encryption type and a
pre-shared key passphrase
• WPA-PSK uses the TKIP encryption type with 
authentication from a RADIUS server.
• WPA2-PSK uses the AES encryption type with 
authentication from a RADIUS server.
• For more information about WPA, see “Configuring 
WPA-PSK or WPA2-PSK Wireless Security” on 
page 2-8.

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 ga teway. 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.
Note: NETGEAR’s Push N Connect feature based on the Wi-Fi Protected Setup 
(WPS) standard (for more information, see  http://www.wi-fi.org). All other Wi-
Fi-certified and WPS-capable products  should be compatible with NETGEAR 
products that implement Push N Connect.
Some considerations regarding WPS are:
• WPS supports only WPA-PSK and WPA2-PSK  wireles
 s 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 .
A WPS client can be added using the Pu sh 
 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 us ing 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 wi ll 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 W
 ireless 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 gate
 way as described in “Logging In to Your Gateway” on page  1-4 .
