Configuring Your Wireless Settings

First configure your wireless network connection, then configure your Wireless Access Point

settings. Lastly, configure your Wireless Security Type that matches your network configuration.

To configure your wireless network and enable your wireless access point:

1.

Select Network Configuration from the main menu and Wireless Settings from the submenu.

The Wireless Settings screen will display (as shown in

Figure 3-3

).

2.

Enter your Wireless Network Name (SSID). The default SSID is NETGEAR, but NETGEAR

strongly recommends that you change your Network Name to a different value. It can be up to

32 alphanumeric characters and is case sensitive.

3.

Select the correct Country/Region setting to comply with local regulatory requirements

(

“Understanding Wireless Settings” on page 3-3

for an explanation of these settings).

4.

Select the appropriate Operating Mode for your area and antenna configuration—802.11b/g, b

only, or g only.

5.

The

Enable Allow Broadcast Name (SSID)

radio box is checked (enabled) by default. When

enabled, the SSID will broadcast its name to all Wireless Stations. Stations which have no

SSID (or a “null” value) can then adopt the correct SSID for connections to this Access Point.

6.

Check the

Enable Wireless Access Point

radio button to turn on the wireless radio.

Wireless Configuration

v1.0, April 2007

1.

Select the Wireless Security Type option you wish to use for your Wireless Network. The

options are described in

“Wireless LANs” on page 3-4

.

•

None

: No data encryption is used.

•

WEP

. This enables WEP and requires at least one shared key (see

“Configuring WEP” on

page 3-10

).

•

WPA-PSK.

Uses standard WPA-PSK encryption (see

“Configuring WPA-PSK” on

page 3-12

).

•

WPA2-PSK

. WPA2 is a later version that uses only AES encryption (see

“Configuring

WPA2-PSK” on page 3-13

.)

•

WPA-PSK and WPA2-PSK

. Allows clients to use either WPA (with TKIP encryption) or

WPA2 (with AES encryption) (see

“Configuring WPA-PSK and WPA2-PSK” on

page 3-14

.)

•

WPA with RADIUS

.

This version of WPA requires the use of a RADIUS server for

authentication.(see

“Configuring WPA-PSK” on page 3-12

.).

•

WPA2 with RADIUS.

This is later version of WPA and requires the use of a RADIUS

server (see

“Configuring WPA2 with RADIUS” on page 3-16

.)

•

WPA and WPA2 with RADIUS

. This version of WPA and WPA2 allows the use of either

AES or TKIP encryption with the RADIUS server (see

“Configuring WPA and WPA2

with RADIUS” on page 3-17

.).

Configuring WEP

To configure WEP data encryption:

1.

Select Network Authentication from the main menu and Wireless Settings from the submenu.

2.

In the Wireless Security Type section, select the WEP radio box.

3.

From the WEP section, define the WEP security characteristics:

•

Select Authentication type from the drop-down menu:

–

•

Select which encryption strength you want to use from the Encryption drop-down menu

(64 bits, 128 bits, or 152 bits).

•

Enter a WEP Passphrase (a word or group of printable characters) in the Passphrase box

and click Generate Keys to automatically configure the WEP Key(s).

You can manually or automatically program the four data encryption keys. These values

must be identical on all PCs and devices in your network. Choose either:

–

Automatic – Click

Generate

. The four key boxes will be automatically populated

with key values.

–

Manual – Enter the number of hexadecimal digits appropriate to the encryption

strength: 10 digits for 64-bit and 26 digits for 128-bit (any combination of 0-9, a-f, or

A-F).

•

Select the key to be used as the default key by checking the radio box. (Data transmissions

are always encrypted using the default key.)

See the document “Wireless Communications” for a full explanation of each of these

options, as defined by the IEEE 802.11 wireless communication standard. A link to this

document on the NETGEAR website is in

Appendix B, “Related Documents

.”

to save your settings.

Note:

64-bit and 128-bit are the standard encryption strength options. 152-bit key

length is a proprietary mode that will only work with other wireless devices

that support this mode.

Configuring WPA-PSK

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 include the client software that

supports WPA. Nevertheless, the wireless adapter hardware and driver must also support WPA.

Consult the product document for your wireless adapter and WPA client software for instructions

on configuring WPA settings.

To configure WPA-PSK:

1.

From the

Wireless Security Type

section, select

WPA

.

WPA with PSK

will be selected by

default.

2.

Select the Data Encryption mode: AES or TKIP (TKIP is the default).

3.

Enter the Passphrase (Network Key). The 256-bit key used for encryption is generated from

the Passphrase.

4.

Enter the Key Lifetime (in minutes). This determines how often the encryption key is changed.

(Shorter periods give better security, but adversely affect performance.)

5.

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 wireless firewall from a wired computer

to make any further changes.

Configuring WPA2-PSK

Not all wireless adapters support WPA2. Furthermore, client software is required on the client.

Make sure your client card supports WPA2. Consult the product document for your wireless

adapter and WPA2 client software for instructions on configuring WPA2 settings.

To configure WPA2-PSK:

1.

From the

Wireless Security Type

section, select the

WPA2

radio button. By default

WPN

with PSK

will be selected and

Encryption

will be set to

AES

.

2.

Enter the preshared Passphrase (Network Key).The 256-bit key used for encryption is

generated from the Passphrase.

3.

Enter the Key Lifetime (in minutes). This determines how often the encryption key is changed.

(Shorter periods give better security, but adversely affect performance.)
