.
11.
Make sure that the
Turn Access Control On
check box is
not
selected.
12.
Configure and test your wireless computer for wireless connectivity.
Program the wireless adapter of your computer to have the same SSID and channel that you
specified in the router, and disable encryption. Check that your computer has a wireless link
and can obtain an IP address by DHCP from the router.
Note:
If you are configuring the router from a wireless computer and you change the
router’s SSID, channel, or security settings, you will lose your wireless
connection when you click
Apply
. You must then change the wireless settings
of your computer to match the router’s new settings.

Once your computer has basic wireless connectivity to the router, you can configure the advanced
wireless security functions of the computer and router (for more information about security and
these settings, see

Safeguarding Your Network
The Wireless-N 300 Router Model WNR2000v2 provides highly effective security features, which
are covered in detail in this chapter.
This chapter includes the following sections:

“Recording Basic Wireless Settings Setup Information” on page 2-5
•
“Changing Wireless Security Settings” on page 2-6
•
“Viewing Advanced Wireless Settings” on page 2-12

•
“Backing Up Your Configuration” on page 2-22
•
“Understanding Your Firewall” on page 2-23
•
“Adding Guest Networks” on page 2-23
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.
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.
To configure the wireless network, you can:
•
Manually specify your SSID and your wireless security settings
. The WNR2000v2 router
provides two screens for configuring the wireless settings:
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 2-21
.

1) Open system: easy but no security
2) MAC access list: no data security
3) WEP: security but some performance
impact
4) WPA-PSK: strong security
5) WPA2-PSK: very strong security

. You access these under Setup in the main menu (see
“Viewing Basic
Wireless Settings” on page 2-6
).
–
Advanced Wireless Settings
. You access these under Advanced in the main menu (see
“Viewing Advanced Wireless Settings” on page 2-12
).
•
Use Wi-Fi Protected Setup (WPS) to automatically set the SSID and implement WPA/
WPA2 security on both the router and the client device
. If the clients in your network are
WPS capable, you can use Wi-Fi Protected Setup (WPS) to automatically set the SSID and
implement WPA/WPA2 security on both the router and the client device (see
“Using Push 'N'
Connect (Wi-Fi Protected Setup)” on page 2-13
).
Basic security options are listed in order of increasing effectiveness in
Table 2-1
. Other features
that affect security are listed in
Table 2-2 on page 2-4
. For more details on wireless security
methods, click the link to the online document
“Wireless Networking Basics” in Appendix B
.
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 2-9
.
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 2-10
