such as WinPOET to access the Internet, your Internet connection requires a login. After you 
select Ye s, the Basic Settings screen displays.
–Internet Service Provider. This drop-down list contains a few ISPs that need special 
protocols for connection. The list includes:
•PPTP (Point to Point Tunneling Protocol), used primarily in Austrian DSL services
Figure 1-5
Note: After you finish setting up your router, you will no longer need to launch the 
ISP’s login program on your computer to access the Internet. When you start 
an Internet application, your router will automatically log you in.

Safeguarding Your Network
The Wireless-G Router Model WGR614v9 provides highly effective security features, which are 
covered in detail in this chapter. 
This chapter includes the following sections:
•“Choosing Appropriate Wireless Security”
•“Recording Basic Wireless Settings Setup Information” on page 2-4
•“Changing Wireless Security Settings” on page 2-5
•“Viewing Advanced Wireless Settings” on page 2-10
•“Restricting Wireless Access by MAC Address” on page 2-11
•“Restricting Wireless Access by MAC Address” on page 2-11
•“Changing the Administrator Password” on page 2-14
•“Backing Up Your Configuration” on page 2-15
•“Understanding Your Firewall” on page 2-15
Choosing Appropriate Wireless Security 
Unlike wired networks, wireless networks allow anyone with a compatible adapter to receive your 
wireless data transmissions well beyond your walls. Operating an unsecured wireless network 
creates an opportunity for outsiders to eavesdrop on your network traffic or to enter your network 
to access your computers and files. Indoors, computers can connect over 802.11g/n wireless 
networks at ranges of up to 300 feet. Such distances can allow for others outside your immediate 
area to access your network. Use the security features of your wireless equipment that are 
appropriate to your needs.
The time it takes to establish a wireless connection can vary depending on both your security 
settings and router placement. 
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 compared to 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.

v1.1, May 2008
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.
The Wireless-G Router provides two screens for configuring the wireless settings: the basic 
Wireless Settings screen, which you access under Setup in the main menu (see “Changing Wireless 
Security Settings” on page 2-5), and the Advanced Wireless Settings screen, which you access 
under Advanced (see “Changing Wireless Security Settings” on page 2-5).
Basic security options are listed in order of increasing effectiveness in Ta b l e 2 - 1 below. Other 
features that affect security are listed in Table 2-2 on page 2-3. For more details on wireless 
security methods, see the online document “Wireless Networking Basics” in Appendix B.
Note: NETGEAR recommends that you 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. For information 
about how to change the administrator password, see “Changing the Administrator 
Password” on page 2-14.

Safeguarding Your Network 2-3
v1.1, May 2008 Table 2-1.  Wireless Security Options
Security Type Description
None. No wireless security. Recommended only for 
troubleshooting wireless connectivity. Do not run an 
unsecured wireless network unless it is your 
intention to provide free Internet access for the 
public.
WEP. Wired Equivalent Privacy.  Wired Equivalent Privacy (WEP) data encryption 
provides moderate data security. WEP Shared Key 
authentication and WEP data encryption can be 
defeated by a determined eavesdropper using 
publicly available tools.
For more information, see “Configuring WEP 
Wireless Security” on page 2-7.
WPA-PSK (TKIP). WPA-PSK standard encryption 
with TKIP encryption type.
WPA2-PSK (AES). Wi-Fi Protected Access version 2 
with Pre-Shared Key; WPA2-PSK standard 
encryption with the AES encryption type.
WPA-PSK (TKIP) + WPA2-PSK (AES). Mixed mode.Wi-Fi Protected Access with Pre-Shared Key (WPA-
PSK and WPA2-PSK) data encryption provides 
extremely strong data security, very effectively 
blocking eavesdropping. Because WPA and WPA2 
are relatively new standards, older wireless adapters 
and devices might not support them.
For more information, see “Configuring WPA-PSK 
and WPA2-PSK Wireless Security” on page 2-9.
Table 2-2.  Other Features That Enhance Security
Security TypeDescription
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 2-10.
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 2-10.

Recording Basic Wireless Settings Setup Information
Before 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: 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.
Restrict access based on MAC address.You can restrict access to only trusted computers so 
that unknown computers cannot wirelessly connect 
to the Wireless-G 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 2-11.
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 2-15.
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.

–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:
–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 Wireless-G 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 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 
WGR614v9 default SSID is NETGEAR. You can disable this broadcast as described in 
“Viewing Advanced Wireless Settings” on page 2-10. 
•Region. This field identifies the region where the Wireless-G 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.
Figure 2-2
Note: The region selection feature might not be available in all countries.
