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. For more details on
wireless security methods, please see
“Wireless Communications” in Appendix B
.
Recommended Security Settings
Stronger security methods can entail a cost in terms of throughput, latency, battery consumption,
and equipment compatibility. In choosing an appropriate security level, you can also consider the
effort versus the reward for a hacker to break into your network. As a minimum, however,
NETGEAR recommends using WEP with Shared Key authentication. Do not run an unsecured
wireless network unless it is your intention to provide free Internet access for the public.
In addition, be sure to change the administration password of your router. Default passwords are
well-known, and an intruder can use your administrator access to read or disable your security
settings. To change the administrator password, see
“Changing the Administrator Password” on
page 3-14
.
Changing Wireless Security Settings
This section describes the security-related wireless settings. For details on the configuration of the
general wireless settings, see
“Configuring Wireless Settings” on page 2-10
.
To configure the wireless security settings of your router:
1.
Log in to the WNR834B router at its default LAN address of
www.routerlogin.net
(or
192.168.1.1
) with its default user name of
admin
and default password of
password
, or
using whatever LAN IP address and password you have set up.

2.
From the main menu of the browser interface, under Setup, click Wireless Settings. The
Wireless Settings menu appears.
The available settings in this menu are:
•
Name (SSID)
The SSID, also known as the wireless network name, is broadcast by the wireless router so
that nearby wireless devices can discover your network. You can disable this broadcast as
described in
“Configuring Security in the Advanced Wireless Settings Menu” on page 3-6
.
•
Region
This field identifies the region where the WNR834B can be used.
•
Channel
This field determines which operating frequency is used.
•
Mode
This field determines which 802.11 data communications protocol is used.

Security Options
These options are the wireless security features you can enable.
Table 3-1
identifies the basic
wireless security options. For a detailed explanation of these standards, see
“Wireless
Communications” in Appendix B
.
Balancing performance factors (throughput, latency, battery consumption, and equipment
compatibility) against the value of information on your network, select an appropriate security
level. As a minimum, NETGEAR recommends using WEP with Shared Key authentication.
Note:
The Security Options displayed in this menu may change depending on the current
selection of Wireless Mode.
Table 3-1.
Basic Wireless Security Options
Field
Description
None
No wireless security. Only recommended for troubleshooting wireless connectivity.
WEP
WEP offers the following options:
•
Open System
With Open Network authentication and 64- or 128-bit WEP Data Encryption, the WNR834B
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 in order to join
the network. Choose 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 box.
Manually entered keys
are not
case sensitive but passphrase characters
are
case sensitive.
Note
: Not all wireless adapter configuration utilities support passphrase key generation.
• Auto
The wireless router automatically detects whether Open System or Shared Key is used.
WPA-PSK
WPA2-PSK
WPA-Pre-shared Key
does
perform authentication. WPA-PSK uses TKIP (Temporal Key
Integrity Protocol) data encryption and WPA2-PSK uses AES (Advanced Encryption Standard)
data encryption. Both methods dynamically change the encryption keys making them nearly
impossible to circumvent.
Enter a word or group of printable characters in the Password Phrase box. These characters
are
case sensitive.
Note
: Not all wireless adapter configuration utilities support WPA-PSK and WPA2-PSK.
Furthermore, client software is required on the client. Windows XP Service Pack 2 and
Windows XP Service Pack 1 with WPA patch do include the client software that supports WPA.
However, the wireless adapter hardware and driver must also support WPA.

Configuring Security in the Advanced Wireless Settings Menu
To configure security in the Advanced Wireless Settings menu:
1.
From the main menu of the browser interface, under Advanced, click Wireless Settings. The
Advanced Wireless Settings menu appears.
The security-related wireless settings are described below. For details on the configuration of the
general wireless settings, see
“Configuring Wireless Settings” on page 2-10
.
•
Enable Wireless Router Radio
If you disable the wireless router radio, wireless devices cannot connect to the WNR834B. If
you will not be using your wireless network for a period of time, you can deselect this
checkbox and disable all wireless connectivity.
•
Enable SSID Broadcast
Deselect this checkbox to disable broadcast of the SSID, so that only devices that know the
correct SSID can connect. Disabling SSID broadcast nullifies the wireless network ‘discovery’
feature of some products such as Windows XP.
•
Wireless Card Access List
When a Wireless Card Access List is configured and enabled, the WNR834B checks the MAC
address of any wireless device attempting a connection, and only allows connections to
computers identified on the trusted computers list. For instructions on configuring the
Wireless Card Access List, see
“Restricting Wireless Access by MAC Address” on page 3-12
.

Information to Gather Before Changing Basic Wireless Settings
Before customizing your wireless settings, print this form 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 will be able to 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 below.
•
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:
Open System
,
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 below.
•
Passphrase Method
. ______________________________
These characters
are
case
sensitive. Enter a word or group of printable characters and click Generate Keys. 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 or a–f). For 128-bit WEP, enter 26
hexadecimal digits.
Key 1: ___________________________________
Key 2: ___________________________________
Key 3: ___________________________________
Key 4: ___________________________________
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.
