Configuring WEP

Wired Equivalent Privacy (WEP) security is the most basic and simplest form of wireless security.

It is the most often used, but least secure of the available options. WEP Shared Key authentication

and WEP data encryption block all but the most determined eavesdropper. This data encryption

mode has been superseded by WPA-PSK and WPA2-PSK.

To configure WEP data encryption:

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 LAN address and

password you have set up.

2.

Select

Wireless Settings

in the main menu.

3.

In the Security Options section of the screen, select

WEP (Wired Equivalent Privacy)

. The

WEP Security Encryption section displays.

4.

Select the authentication type:

•

Automatic

.This is the default setting.

•

Open System

.

•

Shared Key

5.

Select the encryption strength setting:

•

64-bit WEP

.

•

128-bit WEP

.

6.

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

encryption keys. These values must be identical on all computers and access points in your

network.

•

Automatic. Enter a word or group of printable characters in the

Passphrase

field and click

Generate

. The four key boxes are automatically populated with key values.

•

Manual. The number of hexadecimal digits that you must enter depends on the encryption

strength setting:

–

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 (any combination of 0–9, a–f, or A–F).

7.

Select the radio button for the key you want to make active.

Be sure that you clearly understand how the WEP key settings are configured in your wireless

adapter. Wireless adapter configuration utilities such as the one included in Windows XP

allow entry of only one key, which must match the default key you set in the modem router.

8.

Click

Save

to save your settings or click

Apply

to allow your changes to take effect

immediately.

Configuring WPA-802.1x

This version of WPA requires the use of a RADIUS server for authentication. Each user (wireless

client) must have a user login on the RADIUS server, and the modem router must have a client

login on the RADIUS server. Data transmissions are encrypted using a key that is automatically

generated.

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 LAN address and

password you have set up.

2.

Select

Wireless Settings

in the main menu.

Note:

When configuring the modem router from a wireless computer, if you specify WEP

settings, you will lose your wireless connection when you click

Apply

. You must

then either configure your wireless adapter to match the modem router WEP

settings or access the modem router from a wired computer to make any further

changes.

3.

In the Security Options section of the screen, select

WPA-802.1x

.

4.

In the

Radius Server Name/IP Address

field, enter the name or IP address of the RADIUS

server on your LAN. This is a required field.

5.

In the

Radius Port

field, enter the port number used for connections to the RADIUS server.

The default port is 1812.

6.

In the

Shared Key

field, enter the value that you want to use for the RADIUS shared key. This

key enables the modem router to log in to the RADIUS server and must match the client login

value used on the RADIUS server.

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 modem router’s SSID and security settings and, at the same time, connect the wireless client

securely and easily to the modem router. Look for the

symbol on your client device

1

(computers that will connect wirelessly to the modem router are clients). WPS automatically

configures the SSID and wireless security settings for the modem router (if the modem router is in

its default state) and broadcasts these settings to the wireless client.

Some considerations regarding WPS are:

•

WPS supports only WPA-PSK and WPA2-PSK wireless security. WEP security is not

supported by WPS.

•

NETGEAR’s Push 'N' Connect feature is based on the Wi-Fi Protected Setup (WPS) standard.

All other Wi-Fi-certified and WPS-capable products should be compatible with NETGEAR

products that implement Push 'N' Connect.

•

If your wireless network will include a combination of WPS capable devices and non-WPS

capable devices, NETGEAR suggests that you set up your wireless network and security

settings manually first, and use WPS only for adding additional WPS capable devices. See

“Connecting Additional Wireless Client Devices After WPS Setup” on page 2-20

.

•

If the modem router has already been configured manually, and either WPS-PSK or WPA2-

PSK security has been enabled, a wireless client can be connected quickly and simply by using

the WPS method of connecting to the wireless network. In this case, the existing wireless

settings are broadcast to the WPS-capable client.

These instructions assume that you are configuring WPS on the modem router for the first time

and connecting a WPS-capable device.

To set up basic wireless connectivity:

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 LAN address and

password you have set up.

2.

Select

Add WPS Client

(computers that will connect wirelessly to the router are clients) in

the main menu. The Add WPS Client wizard screen displays.

3.

Click

Next.

The screen changes to allow you to select the method for adding the WPS client.

4.

Select the method for adding the WPS client. A WPS client can be added using the Push

Button method or the PIN method.

•

Using the Push Button

. This is the preferred method. (See

Figure 2-6 on page 2-19

.)

–

Select the

Push Button

radio box and either press the WPS Push Button on the side of

the modem router or click the soft WPS Push Button on the screen (as shown below).

–

The modem router will attempt to communicate with the client; you have 2 minutes to

enable WPS from the client device using the client’s WPS networking utility.

You can also enter either of these addresses to connect to the modem router:

http://www.routerlogin.net

or

:

•

Entering a PIN

. If you want to use the PIN method, select the

PIN

radio box. A screen

similar to the one shown below displays.

–

Go to your wireless client and, from the client’s WPS utility, obtain the wireless

client’s security PIN, or follow the client’s WPS utility instructions to generate a

security PIN.

–

Then, enter this PIN in the

Enter Client’s PIN

field provided on the modem router

and click

Apply

. You have 4 minutes to enable WPS on the router using this method.

Using either method, the client wireless device will attempt to detect the WPS signal from the

modem router and establish a wireless connection in the time allotted.

•

While the modem router attempts to connect to a WPS-capable device, the Push 'N'

Connect LED on the front of the modem router blinks green. When the modem router has

established a WPS connection, the LED is solid green.
