Description

Wireless Network

Name (SSID)

The SSID is also known as the wireless network name.

Enter a 32-character (maximum) name in this field. The

characters are case sensitive.

In a setting where there is more than one wireless

network, different wireless network names provide a

means for separating the traffic. Any device you want to

participate in a wireless network must use the SSID.

Control Channel

The wireless channel used by the gateway. The default is

channel 11.

You should not need to change the wireless channel

unless you experience interference (shown by lost

connections and/or slow data transfers). Should this

happen, you might need to try different channels to see

which is the best.

802.11 Mode

Select the desired wireless mode. The options are:

• Auto

•

b & g only

. Only 802.11g and 802.11b wireless stations

can be used.

•

g only

. Only 802.11g wireless stations can be used.

•

b only

. Only 802.11b wireless stations can be used.

Wireless Access

Point

Enable Wireless Access

Point

On by default, you can also turn off the wireless radio to

disable access through this device. This can be helpful

for configuration, network tuning, or troubleshooting

activities.

Allow Broadcast Name

(SSID)

On by default, the gateway broadcasts its SSID, allowing

wireless stations which have a “null” (blank) SSID to

adopt the correct SSID. The default SSID is NETGEAR.

If you disable broadcast of the SSID, only devices that

have the correct SSID can connect. This nullifies the

wireless network “discovery” feature of some products

such as Windows XP, but the data is still fully exposed to

a determined snoop using specialized test equipment

like wireless sniffers. For this reason NETGEAR

recommends that you also enable wireless security.

Wi-Fi Protected

Setup (WPS)

WPS Config

To use WPS, you must enable WPS Config and click

Apply

.

Device Name

The default is NetgearAP. This identifies your gateway

for client WPS devices that want to join the network.

STA PIN

The PIN is displayed so that you can use it to configure

the gateway through WPS (Wi-Fi Protected Setup). It is

also displayed on the gateway’s label.

WPS Method

PIN or Push Button can be used.

Start WPS

If WPS Config is enabled, clicking

Start WPS

causes the

gateway to try to associate with a client. If security is set

to Disable, it is automatically set to WPA-PSK. For more

information about WPS, see

“Using Push 'N' Connect

(WPS) to Configure Your Wireless Network and Security”

on page 2-9

.

Security Options

Disable

Wireless security is disabled by default. After the

gateway is connected to the Internet, NETGEAR strongly

recommends that you implement wireless security.

Security Options

(continued)

•

WEP (Wired Equivalent

Privacy) 64-bit encryption

•

WEP (Wired Equivalent

Privacy) 128-bit encryption

WEP security uses encryption keys to provides data

security. You can select 64-bit or 128-bit encryption. See

“Configuring WEP (Wired Equivalent Privacy) Wireless

Security” on page 2-7

.

•

WPA-PSK (Wi-Fi

Protected Access Pre-

Shared Key)

• WPA

•

WPA2-PSK (Wi-Fi

Protected Access 2 Pre-

Shared Key)

• WPA2

Wi-Fi Protected Access (WPA) data encryption provides

data security. The very strong authentication along with

dynamic per frame rekeying of WPA make it virtually

impossible to compromise.

•

WPA uses the TKIP encryption type and a

pre-shared key passphrase

•

WPA-PSK uses the TKIP encryption type with

authentication from a RADIUS server.

•

WPA2-PSK uses the AES encryption type with

authentication from a RADIUS server.

•

WPA-PSK or WPA2-PSK Wireless Security” on

Configuring WEP (Wired Equivalent Privacy) Wireless Security

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 gateway from a wired computer to make further

changes.

To configure WEP data encryption:

1.

Log in to the gateway as described in

“Logging In to Your Gateway” on page 1-4

.

2.

In the main menu, under Setup, select Wireless Settings.

3.

In the Wireless Settings screen, depending on the encryption strength that you want, select one

of these options:

•

WEP (Wired Equivalent Privacy) 64-bit encryption

•

WEP (Wired Equivalent Privacy) 128-bit encryption

Settings for WEP encryption are shown in the following figure (which is the bottom part of the

Wireless Settings screen).

Figure 2-2

Select the WEP security encryption from the

Authentication

drop-down list. Select

Automatic

,

Open System

or

Shared Key

. The default is

Automatic

5.

Enter the WEP encryption key information:

•

WEP PassPhrase

:

To use a passphrase to automatically generate the keys, enter a

passphrase and click

Generate

. Wireless stations must use the passphrase or keys to

access the gateway.

•

Key 1

through

Key 4

: You can manually enter the four data encryption keys. These values

must be identical on all computers and access points in your network. For 64-bit WEP,

enter 10 hexadecimal digits (any combination of 0–9 or A–F). For 128-bit WEP, enter

26 hexadecimal digits.

•

Select which of the four keys will be the default. Data transmissions are always encrypted

using the default key. The other keys can only be used to decrypt received data. The four

entries are disabled if WPA-PSK or WPA authentication is selected.

6.

Click

Apply

to save your settings.

Note:

If you use a wireless computer to configure WEP settings, you will be

disconnected when you click

Apply

. Reconfigure your wireless adapter to match

the new settings or access the gateway from a wired computer to make any further

changes.

Configuring WPA-PSK or WPA2-PSK Wireless Security

Note:

Not all wireless adapters support WPA. Furthermore, client software is required on

the client. Windows XP and Windows 2000 with Service Pack 3 or above do

include the client software that supports WPA. The wireless adapter hardware and

driver must also support WPA. Consult the product documentation for your

wireless adapter and WPA client software for instructions on configuring WPA

settings.

To configure WPA in the gateway:

1.

Log in to the gateway as described in

“Logging In to Your Gateway” on page 1-4

.

2.

In the main menu, under Setup, select Wireless Settings.

Using Push 'N' Connect (WPS) to Configure Your Wireless

Network and Security

If your wireless clients support Wi-Fi Protected Setup (WPS), you can use this feature to configure

the gateway’s SSID and security settings and, at the same time, connect the wireless client securely

and easily to the gateway. Look for the

symbol on your client device (computers that will

connect wirelessly to the gateway are clients). WPS uses the network name (SSID) that is
