NETGEAR-DualBand-N. The default 11G SSID is NETGEAR-2.4-G.
-
The wireless mode (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.

•
Push 'N' Connect (WPS) automatically implements wireless security on the N300 wireless
modem 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 N300 wireless modem router,
clicking an onscreen WPS button, or entering a PIN number. This generates a new SSID
and implements WPA/WPA2 security.
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.
To set up your wireless network using the WPS feature:
-
Use the N300 wireless modem router dome, which works as a WPS button (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 WPA2 capable, and that they support WPS configuration.

Wireless Placement and Range Guidelines
The range of your wireless connection can vary significantly based on the physical placement
of the N300 wireless modem 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 N300 wireless modem 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 (see
Interference Reduction Table
on page
169).
•
Away from large metal surfaces.

•
Put the antenna in a vertical position to provide the best side-to-side coverage. Put the
antenna in a horizontal position to provide the best up-and-down coverage.
•
If you are 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. WEP connections can take slightly longer to establish. Also, WEP
encryption can consume more battery power on a notebook computer.
Wireless Security Options
Indoors, computers can connect over 802.11g wireless networks at a maximum 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 N300 wireless modem 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:
Figure 8.
•
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 rekeying of WPA makes it virtually
impossible to compromise.
Wireless data
1) Open system: easy but no security.
2) WEP: security, but some performance impact.
3) WPA-PSK: strong security.
4) WPA2-PSK: very strong security.

Note:
NETGEAR recommends WPA2 security because it is the strongest,
and WPA security as the next strongest. WEP security is the
weakest of these alternatives, but you might need to use WEP
security to be able to link with your older wireless devices.

Manually Configuring Your Wireless Settings
You can view or manually configure the wireless settings for the N300 wireless modem router
in the Wireless Settings screen. If you want to make changes, make sure to note the current
settings first.
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, use a computer with a wired
connection to access the N300 wireless modem router.
To view or manually configure the wireless settings:
1.
Log in to the N300 wireless modem router at its default LAN address of
or
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 N300 wireless modem router.

The settings for this screen are explained in the following table.
Settings
Description
Name (11N SSID)
Name (11G SSID)
This is 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 that you
want to participate in a wireless network must use the SSID.
Region
The location where the N300 Wireless Modem Router is used.
Mode
Specify which 802.11 data communications protocol is used. You can select one
of the following modes:
•
Up to 300 Mbps at 2.4 GHz
. Performance mode, using channel expansion to
achieve the 270 Mbps data rate. The N300 wireless modem router uses the
channel you selected as the primary channel and expands to the secondary
channel (primary channel +4 or –4) to achieve a 40 MHz frame-by-frame
bandwidth. The N300 wireless modem router detects channel usage and
disables frame-by-frame expansion if the expansion would result in
interference with the data transmission of other access points or clients.
•
Up to 300 Mbps at 5 GHz and 54 Mbps at 2.4 GHz
. This is the default mode,
which is recommended.
•
Up to 145 Mbps at 2.4 GHz
. 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.
•
Up to 145 Mbps at 5 GHz and 54 Mbps at 2.4 GHz
. Legacy mode, for
compatibility with the slower 802.11b and 802.11g wireless devices.

For initial configuration and test, leave the other settings unchanged.
5.
To save your changes, click
Apply
.
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 N300 wireless modem router. Check that they have a wireless
link and are able to obtain an IP address by DHCP from the N300 wireless modem router.
If there is interference, adjust the channel.
Configuring WEP Wireless Security
Note:
If you use a wireless computer to configure wireless security
settings, you will be disconnected when you click
Apply
.
Reconfigure your wireless computer to match the new settings, or
access the N300 wireless modem router from a wired computer to
make further changes.
11N Channel
11G Channel
The wireless channel fields determine the operating frequency used for the 11N
or 11G wireless networks. 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.
