Configuring Your Wireless Network and Security Settings

v1.0, March 2010

You also can increase your security by implementing one or more of the following features:

•

Restrict Access Based on MAC Address

. You can allow only trusted PCs to connect so that

unknown PCs cannot wirelessly connect to the modem router. Restricting access by MAC

address adds an obstacle against unwanted access to your network, but the data broadcast over

the wireless link is fully exposed (see

“Restricting Access by MAC Address” on page 2-17

).

•

Turn Off the Broadcast of the Wireless Network Name SSID

. If you disable broadcast of

the SSID, only devices that have the correct SSID can connect. This nullifies wireless network

‘discovery’ feature of some products, such as Windows XP, but the data is still exposed (see

“Controlling Wireless Station Access” on page 2-16

).

For more information about wireless technology, see the link to the online document in

“Wireless

Communications” in Appendix C

.

Manually Configuring Your Wireless Network

You can view or manually configure the wireless settings and wireless security for the modem

router in the Wireless Settings screen. If you want to make changes, make sure to note the current

settings first.

To manually configure the wireless settings:

1.

Log in to the modem router at its default LAN address of

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 modem router.

2.

Select Wireless Settings from the main menu to display the Wireless Settings screen:

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 problem, use a computer with a wired connection to access the modem

router.

The settings for this screen are explained in

Table 2-1 on page 2-6

.

3.

Select the region in which the modem router will operate.

4.

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. After testing your wireless

connectivity, select a security method (see

“Configuring Your Wireless Security” on page 2-7

).

Set up your wireless computers with the same SSID and wireless security settings as your

modem router. Check that they have a wireless link and are able to obtain an IP address by

DHCP from the modem router. If there is interference, adjust the channel.

Description

Wireless Network

Name (SSID)

The SSID is also known as the wireless network

name. Enter a 32-character (maximum) name. This

field is case-sensitive.

Wireless network names provide a means for

separating traffic for different networks. Any device

you want to join a wireless network must use the

SSID.

Region

The location where the modem router is used.

Channel

The wireless channel used by the gateway. The

default is auto.

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 try different channels to see which is the

best.

Mode

The default is b & g, which allows both 802.11g and

802.11b wireless stations access. Note that in b only

mode, 802.11g wireless stations can connect if they

can operate in 802.11b mode.

Wireless Access Point

Enable Wireless

Access Point

Selected by default, this setting enables the wireless

radio, which allows the modem router to work as a

wireless access point.

Turning off the wireless radio can be helpful for

configuration, network tuning, or troubleshooting.

Allow Broadcast

Name (SSID)

Selected by default, the modem router broadcasts its

SSID, allowing wireless stations that have a null

(blank) SSID to adopt the correct SSID. If you

disable broadcast of the SSID, only devices with the

correct SSID can connect. This nullifies the wireless

network discovery feature of products such as

Windows XP, but the data is still exposed to

equipment like wireless sniffers. For this reason

NETGEAR recommends that you also enable

wireless security.

Wireless Isolation

This feature is disabled by default. If it is enabled,

wireless stations cannot communicate with each

other or with stations on the wired network.

Wireless Station Access

List

Turn Access Control

On

Access control is disabled by default so that any

computer configured with the correct SSID can

connect. See

“Restricting Access by MAC Address”

.

Configuring Your Wireless Security

To set up wireless security, you can either manually configure it in the Wireless Settings screen, or

you can use Wi-Fi Protected Setup (WPS) to automatically set the SSID and implement WPA/

WPA2 security (see

“Using Push 'N' Connect (WPS) to Configure Your Wireless Network” on

page 2-10

.

Security Options (see

“Configuring Your

Wireless Security”

).

•

Disabled

. You can use this setting to establish wireless connectivity

before implementing wireless security. NETGEAR strongly recommends

that you implement wireless security.

•

WEP (Wired Equivalent Privacy)

. Use encryption keys and data

encryption for data security. You can select 64-bit or 128-bit encryption.

See

“Configuring WEP”

.

•

WPA-PSK (WiFi Protected Access Pre-Shared Key).

Allow only

computers configured with WPA to connect to the modem router. See

“Configuring WPA, WPA2, or WPA/WPA2”

.

•

WPA2-PSK (Wi-Fi Protected Access with 2 Pre-Shared Keys)

. Allow

only computers configured with WPA2 to connect to the modem router.

See

“Configuring WPA, WPA2, or WPA/WPA2”

.

•

WPA-PSK + WPA2-PSK

. Allow computers configured with either WPA-

PSK or WPA2-PSK security to connect to the modem router. See

“Configuring WPA, WPA2, or WPA/WPA2”

.

• The

WPA-802.1x

,

WPA2-802.1

, and

WPA-802.1x +WPA2-802.1

options

utilize user authentication implemented using IEE 802.1x and Radius

servers. See

“Configuring WPA, WPA2, or WPA/WPA2”

.

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 modem router from a wired computer to make

further changes.

Figure 2-3

Note:

The authentication scheme is separate from the data encryption. You can select

an authentication scheme that requires a shared key but still leaves the data

transmissions unencrypted. If you require strong security, use both the Shared

Key and WEP encryption settings.
