Safeguarding Your Network
For a wireless connection, the
SSID, also called the wireless network name, and the wireless
security setting must be the same for
the wireless router and wireless computers or wireless
adapters. NETGEAR strongly recommends that you use wireless security.
This chapter includes:
•
“Planning Your Wireless Network”
•
“Manually Configuring Your Wireless Settings” on page 2-4
•
“Using Push ‘N’ Connect to Configure Your Wireless Network” on page 2-9
•
“Adding Both WPS-Capable Clients and Non-WPS-Capable Clients” on page 2-14
•
“Restricting Access to Your Router” on page 2-15
Planning Your Wireless Network
For compliance and compatibility between similar products in your area, the operating channel
and region must be set correctly.
To configure the wireless network, you can either specify the wireless settings, or you can use Wi-
Fi Protected Setup (WPS) to automatically set the SSID and implement WPA/WPA2 security.
•
To manually configure the wireless settings, you must know the following:
–
SSID. The default SSID for the wireless router is NETGEAR.
–
The wireless mode (802.11n, 802.11g, or 802.11b) that each wireless adapter supports.
–
Wireless security option. To successfully implement wireless security, check each
wireless adapter to determine which wireless security option it supports.
See
“Manually Configuring Your Wireless Settings” on page 2-4
.
Warning:
Computers can connect wirelessly at a range of several hundred feet. This can
allow others outside of your immediate area to access your network.

•
Push 'N' Connect (WPS) automatically implements wireless security on the wireless router
while, at the same time, allowing you to automatically implement wireless security on any
WPS-enabled devices (such as wireless computers and wireless adapter cards). You activate
WPS by pressing a WPS button on the wireless router, clicking an onscreen WPS button, or
entering a PIN number. This generates a new SSID and implements WPA/WPA2 security.
To set up your wireless network using the WPS feature:
–
Use the WPS button on the side of the wireless router (there is also an onscreen WPS
button), or enter the PIN of the wireless device.
–
Make sure that all wireless computers and wireless adapters on the network are
Wi-Fi
certified and WPA or WPA 2 capable, and that they support WPS configuration.
See
“Using Push ‘N’ Connect to Configure Your Wireless Network” on page 2-9
.
Wireless Placement and Range Guidelines
The range of your wireless connection can vary significantly based on the physical placement of
the wireless router. The latency, data throughput performance, and notebook power consumption
of wireless adapters also vary depending on your configuration choices.
For best results, place your wireless router according to the following guidelines:
•
Near the center of the area in which your PCs will operate.
•
In an elevated location such as a high shelf where the wirelessly connected PCs have line-of-
sight access (even if through walls).
•
Away from sources of interference, such as PCs, microwave ovens, and 2.4 GHz cordless
phones.
•
Away from large metal surfaces.
•
If using multiple access points, it is better if adjacent access points use different radio
frequency channels to reduce interference. The recommended channel spacing between
adjacent access points is 5 channels (for example, use Channels 1 and 6, or 6 and 11).
The time it takes to establish a wireless connection can vary depending on both your security
settings and placement.
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.

Wireless Security Options
Computers can connect over a 802.11g or 802.11n network at a range of up to 300 feet. Such
distances can allow for others outside your immediate area to access your network.
Unlike wired network data, your wireless data transmissions can extend beyond your walls and
can be received by anyone with a compatible adapter. For this reason, use the security features of
your wireless equipment. The WNR3500v2 router provides highly effective security features
which are covered in detail in this chapter. Deploy the security features appropriate to your needs.
There are several ways you can enhance the security of your wireless network:
•
WEP.
Wired Equivalent Privacy (WEP) data encryption provides data security. WEP Shared
Key authentication and WEP data encryption block all but the most determined eavesdropper.
This data encryption mode has been superseded by WPA-PSK and WPA2-PSK.
•
WPA-PSK (TKIP), WPA2-PSK (AES)
. Wi-Fi Protected Access (WPA) using a pre-shared
key to perform authentication and generate the initial data encryption keys. The very strong
authentication along with dynamic per frame re-keying of WPA makes it virtually impossible
to compromise.
For more information about wireless technology, see the link to the online document in
“Wireless
Networking Basics” in Appendix B
.

Manually Configuring Your Wireless Settings
You can view or manually configure the wireless settings for the wireless router in the Wireless
Settings screen. If you want to make changes, make sure to note the current settings first.
To view or manually configure the wireless settings:
1.
Log in to the wireless router at its default LAN address of
with
its default user name of
admin
, and default password of
password
, or using whatever user
name, password, and LAN address you have chosen for the wireless router.
2.
Select Wireless Settings from the main menu to display the Wireless Settings screen:
The settings for this screen are explained in
Table 2-1
.
3.
Select the region in which the wireless router will operate.
4.
For initial configuration and test, leave the other settings unchanged.
5.
To save your changes, click
Apply
.
Note:
If you use a wireless computer to change the wireless network name (SSID) or
wireless security settings, you will be disconnected when you click
Apply
. To
avoid this problem, use a computer with a wired connection to access the wireless
router.

6.
Configure and test your computers for wireless connectivity.
Program the wireless adapter of your computers to have the same SSID and wireless security
settings as your wireless router. Check that they have a wireless link and are able to obtain an
IP address by DHCP from the wireless router. If there is interference, adjust the channel.

Description
Wireless
Network
Name (SSID):
The SSID is also known as the wireless network name. Enter a 32-
character (maximum) name in this field. This field is 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.
Region:
The location where the router is used.
Channel:
The wireless channel used by the gateway. The default is Auto.
Do not change the wireless channel unless you experience interference (shown by
lost connections or slow data transfers). If this happens, you might need to
experiment with different channels to see which is the best.
Mode:
The default is up to 145 Mbps, which allows 802.11n, 802.11g, and 802.11b
wireless stations access.
Security Options
•
