Description
Disable the wireless router radio.
If you disable the wireless router radio, wireless
devices cannot communicate with the router at all.
You might disable this when you are away or when
other users of your network all use wired
connections.
For more information, see
“Viewing Advanced
Wireless Settings” on page 2-11
.
Turn off the broadcast of the wireless network
name SSID.
If you disable the broadcast of the SSID, only
devices that know the correct SSID can connect.
This nullifies the wireless network discovery feature
of some products such as Windows XP, but your data
is still fully exposed to an intruder using available
wireless eavesdropping tools.
For more information, see
“Viewing Advanced
Wireless Settings” on page 2-11
.
Restrict access based on MAC address.
You can restrict access to only trusted computers so
that unknown computers cannot wirelessly connect
to the WNR1000v2 router. MAC address filtering
adds an obstacle against unwanted access to your
network by the general public, but the data broadcast
over the wireless link is fully exposed. This data
includes your trusted MAC addresses, which can be
read and impersonated by a hacker.
For more information, see
“Restricting Wireless
Access by MAC Address” on page 2-18
.
Modify your firewall’s rules.
By default, the firewall allows any outbound traffic
and prohibits any inbound traffic except for
responses to your outbound traffic. However, you
can modify the firewall’s rules.
For more information, see
“Understanding Your
Firewall” on page 2-22
.
Use the Push 'N' Connect feature (Wi-Fi
Protected Setup).
Wi-Fi Protected Setup provides easy setup by
means of a push button. Older wireless adapters and
devices might not support this. Check whether
devices are WPS enabled.
For more information, see
“Using Push 'N' Connect
(Wi-Fi Protected Setup)” on page 2-13

Recording Basic Wireless Settings Setup Information
Before and after customizing your wireless settings, print this section, and record the following
information. If you are working with an existing wireless network, the person who set up or is
responsible for the network can provide this information. Otherwise, you must choose the settings
for your wireless network. Either way, record the settings for your wireless network in the spaces
provided.
•
Wireless Network Name (SSID)
.
______________________________
The SSID identifies
the wireless network. You can use up to 32 alphanumeric characters. The SSID
is
case-
sensitive. The SSID in the wireless adapter card must match the SSID of the wireless router. In
some configuration utilities (such as in Windows XP), the term “wireless network name” is
used instead of SSID.
•
If
WEP Authentication
is used, circle one:
Shared Key
or
Auto
.
–
WEP Encryption Key Size
. Choose one:
64-bit
or
128-bit
. Again, the encryption key
size must be the same for the wireless adapters and the wireless router.
–
Data Encryption (WEP) Keys
. There are two methods for creating WEP data encryption
keys. Whichever method you use, record the key values in the spaces provided.
•
Passphrase Method
. ______________________________ These characters
are
case-sensitive. Enter a word or group of printable characters and click Generate. Not
all wireless devices support the passphrase method.
•
Manual Method
. These values
are not
case-sensitive. For 64-bit WEP, enter 10
hexadecimal digits (any combination of 0–9, a–f, or A–F). For 128-bit WEP, enter
26 hexadecimal digits.
Key 1: ___________________________________
Key 2: ___________________________________
Key 3: ___________________________________
Key 4: ___________________________________
•
If WPA-PSK or WPA2-PSK authentication is used:
Note:
If you select Shared Key, the other devices in the network will not connect
unless they are also set to Shared Key and are configured with the correct key.

Passphrase
. ______________________________ These characters
are
case-sensitive.
Enter a word or group of printable characters. When you use WPA-PSK, the other devices
in the network will not connect unless they are also set to WPA-PSK and are configured
with the correct passphrase. Similarly, when you use WPA2-PSK, the other devices in the
network will not connect unless they are also set to WPA2-PSK and are configured with
the correct passphrase.
Use the procedures described in the following sections to specify the WNR1000v2 router. Store
this information in a safe place.
Changing Wireless Security Settings
This section describes the wireless settings that you can view and configure in the Wireless
Settings screen, which you access under Setup in the main menu.
Viewing Basic Wireless Settings
To specify the wireless security settings of your router:
1.
Log in to the router as described in
“Logging In To Your Wireless Router” on page 1-2.
2.
Select
Wireless Settings
under Setup in the main menu. The Wireless Settings screen
displays
.
The available settings in this screen are:

Name (SSID)
. The SSID is also known as the wireless network name. Enter a value of up to
32 alphanumeric characters. When more than one wireless network is active, different wireless
network names provide a way to separate the traffic. For a wireless device to participate in a
particular wireless network, it must be configured with the SSID for that network. The
WNR1000v2 default SSID is
NETGEAR
. You can disable this broadcast as described in
“Viewing Advanced Wireless Settings” on page 2-11
.
•
Region
. This field identifies the region where the WNR1000v2 router can be used. It might
not be legal to operate the wireless features of the wireless router in a region other than one of
those identified in this field.
•
Channel
. 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 wireless router uses channel bonding technology to extend the
bandwidth for data transmission. For more information about the wireless channel
frequencies, see the online document that you can access from
“Wireless Networking Basics”
in Appendix B
.
•
Mode
. The default mode is
Up to 150Mbps
.
The Mode options are:
–
Up to 54 Mbps - Legacy Mode with maximum speed of up to 54 Mbps for b/g networks.
–
Up to 65 Mbps - Neighbor Friendly Mode - Will not interfere with neighboring wireless
networks.
Note:
The region selection feature might not be available in all countries.
Note:
The maximum wireless signal rate is derived from the IEEE Standard 802.11
specifications. Actual data throughput will vary. Network conditions and
environmental factors, including volume of network traffic, building materials
and construction, and network overhead, lower actual data throughput rate.

–
Up to 150 Mbps - Performance Mode - Maximum Nx speeds up to 150 Mbps. Using
channel expansion to achieve the 150 Mbps data rate, the WNR1000v2 will use the
channel you selected as the primary channel and expand to the secondary channel
(primary channel +4 or –4) to achieve a 40 MHz frame-by-frame bandwidth. The
WNR1000v2 will detect channel usage and will disable frame-by-frame expansion if the
expansion would result in interference with the data transmission of other access points or
clients.
•
Security Options
. 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 router placement.
WEP connections can take slightly longer to establish. Also, WEP, WPA-PSK, and WPA2-
PSK encryption can consume more battery power on a notebook computer, and can cause
significant performance degradation with a slow computer. Instructions for configuring the
security options can be found in
“Choosing Appropriate Wireless Security” on page 2-1
. A
full explanation of wireless security standards is available in the online document that you can
access from
“Wireless Networking Basics” in Appendix B
.

Configuring WEP Wireless Security
WEP Shared Key authentication and WEP data encryption can be defeated by a determined
eavesdropper using publicly available tools.
WEP offers the following options:
•
Automatic
. With the Automatic option, the router will try both Open System and Shared Key
authentication. Normally this setting is suitable. If it fails, select
Open System
or
Shared Key
.
You can also refer to your wireless adapter’s documentation to see what method to use.
•
Open System
. With Open System authentication and 64 or 128 bit WEP data encryption, the
WNR1000v2 router
does
perform data encryption but
does not
perform any authentication.
Anyone can join the network. This setting provides very little practical wireless security.
•
Shared Key
. With Shared Key authentication, a wireless device must know the WEP key to
join the network. Select the encryption strength (64 or 128 bit data encryption). Manually
enter the key values, or enter a word or group of printable characters in the
Passphrase
field.
Manually entered keys
are not
case-sensitive, but passphrase characters
are
case-sensitive.
