Setting up your wireless car

WEP Encryption Keys—After selecting either the 64-bit or 128-bit WEP encryption mode,

it is critical that you generate an encryption key. If the encryption key is not consistent

throughout the entire wireless network, your wireless networking devices will be unable to

communicate with one another. You can enter your key by typing in the hex key manually, or

you can type a passphrase into the “Passphrase” field and click “Generate” to create a key. A

hex (hexadecimal) key is a combination of numbers and letters from A–F and 0–9. For 64-bit

WEP, you need to enter 10 hex characters. For 128-bit WEP, you need to enter 26 hex

characters.

For instance:

AF 0F 4B C3 D4 = 64-bit WEP key

C3 03 0F AF 0F 4B B2 C3 D4 4B C3 D4 E7 = 128-bit WEP key

The WEP passphrase is NOT the same as a WEP key. Your card uses this passphrase to

generate your WEP keys, but different hardware manufacturers might have different

methods on generating the keys. If you have multiple vendors’ equipment in your network,

the easiest thing to do is to use the hex WEP key from your wireless router and enter it

manually into the hex WEP key table in your card’s configuration screen.

WPA

WPA is a new Wi-Fi standard that improves upon the security features of WEP. To use WPA

security, the drivers and software of your wireless equipment must be upgraded to support

it. These updates will be found on your wireless vendor’s Website. There are three types of

WPA security: WPA-PSK (no server), WPA (with radius server), and WPA2.

WPA-PSK (no server) uses what is known as a pre-shared key as the network key. A network

key is a password that is between eight and 63 characters long. It can be a combination of

letters, numbers, or characters. Each client uses the same network key to access the network.

Typically, this is the mode that will be used in a home environment.

WPA (with radius server) is a system where a radius server distributes the network key to the

clients automatically. This is typically found in a business environment.

WPA2 requires Advanced Encryption Standard (AES) for encryption of data, which offers

much greater security than WPA. WPA uses both Temporal Key Integrity Protocol (TKIP) and

AES for encryption.

Most Wi-Fi products ship with security turned off. So once you have your network working,

you need to activate WEP or WPA and make sure all your wireless devices are sharing the

same network key.

IMPORTANT: You must now set all wireless network cards/adapters to match these settings.

Setting up your wireless car

Configuring your wireless G Plus notebook card to use

security

You should already have your wireless router set to use WPA or WEP. You will need to set your

wireless G Plus notebook card to use the same security settings.

Changing the Wireless Security Settings

The Wireless G USB network adapter supports the latest WPA security feature as well as the

legacy WEP security standard. By default, wireless security is disabled.

Your Dynex wireless adapter is equipped with the latest security standard called Wi-Fi

Protected Access 2 (WPA2™) and the legacy security standard called Wired Equivalent Privacy

(WEP). It also supports the Wi-Fi Protected Setup (WPS) specification, which simplifies the

setup of a wireless network. WPS uses familiar methodologies, such as typing in a Personal

Identification Number (PIN) or pushing a button, to enable you to automatically configure

network names and strong WPA/WPA2 data encryption and authentication.

Using Wi-Fi protected setup:

• Encryption key if not using WPS

• Personal Identification Number (PIN) method: Your wireless adapter generates a PIN

to be entered into your router.

• Push Button Configuration (PBC) method: Your wireless adapter can also connect by

using the software pushbutton.

• Manual configuration method: This section lists the default security settings to be set

if you are not using WPS.

WPS uses WPA2 for encryption. It does not provide additional security, but standardized the

method for securing your wireless network. On your client utility, WPS-enabled networks are

indicated by a key icon. You can use either the PBC method or the PIN method to let a device

access your wireless network.

To use the PBC method:

1 Push and hold the WPS button (located on the back of your router) for three seconds.

Initiate the WPS procedure on the client utility within two minutes.

2 Open the WNU and select the network name, then click Connect. Your client

automatically exchanges security information and is added to your wireless network.

You can also initiate the PBS method from the client side.

To use the PIN method:

1 Open the WNU and select the WPS-enabled network, then click Connect.

2 Choose the PIN method option, then complete the WPS procedure on your router. Your

client is automatically enrolled in your wireless network within two minutes.

To enable security, you will first need to determine which standard is used by the router. (See

your wireless router’s guide for directions on how to access the security settings.)

Setting up your wireless car

To access the security settings on your card:

1 Open the WNU.

2 Click the My Connections tab, then click the connection you want to change.

3 Click Edit, then click Advanced to change settings.

1 Select OPEN from the Network Authentication menu on the Wireless Network

Properties tab on the Edit information for a network page.

2 Select WEP from the Data Encryption menu.

3 After selecting your WEP encryption mode, you can enter your key by typing in the hex

key manually, or you can type in a passphrase in the Passphrase field, then click

Generate to create a key.

A hex (hexadecimal) key is a combination of numbers and letters from A–F and 0–9.

For 64-bit WEP, you need to enter 10 hex characters.

For instance:

AF 0F 4B C3 D4 = 64-bit WEP key

Setting up your wireless car

4 Click Save to finish. Encryption in the wireless router is now set. Each of your

computers on your wireless network will now need to be configured with the same

security settings.

Caution: If you are using a wireless client (such as your notebook equipped with a wireless

notebook card) to turn on the security settings in your wireless router, you will temporarily

lose your wireless connection until you activate security on your wireless client. Record the

key prior to applying changes in the wireless router. If you don’t remember the hex key,

your client will be locked out of the wireless router.

Setting up 128-bit WEP encryption:

1 Select OPEN from the Network Authentication menu on the Wireless Network

Properties tab on the Edit information for a network page.

2 Select WEP from the Data Encryption menu.

3 After selecting your WEP encryption mode, you can enter your key by typing in the hex

key manually, or you can type in a passphrase in the Passphrase field, then click

Generate to create a key.

A hex (hexadecimal) key is a combination of numbers and letters from A–F and 0–9.

For 128-bit WEP, you need to enter 26 hex characters.

For instance:

C3 03 0F AF 0F 4B B2 C3 D4 4B C3 D4 E7 = 128-bit WEP key

4 Click Save to finish. Encryption in the wireless router is now set. Each of your

computers on your wireless network will now need to be configured with the same

on the Wireless Network Properties tab on the Edit information for a network page.

2 Select TKIP or AES from the list.

3 Enter your network key. This can be from eight to 63 characters and can be letters,

numbers, or symbols. This same key must be used on all of the clients (network cards)

that you want to include in your network.

4 Click Save to finish. You must now set all clients (network cards) to match these

settings.

Wireless networking utility options

The Options tab on the Wireless Networking Utility (WNU) lets you customize WNU settings.

Troubleshooting

WNU Help

The WNU Help tab lets you access to online and telephone support, as well as advanced

diagnostic tools.

Advanced diagnostic tools

The Advanced Diagnostic Tools section is the central control panel for all the settings of

the hardware and software components of the wireless network. It provides an array of tests

and connectivity services to ensure optimal network performance.

Troubleshooting

Placement of your wireless networking hardware for

optimal performance

Your wireless connection will be stronger the closer your computer is to your wireless router.

Typical indoor operating range for your wireless devices is between 100 and 200 feet. In the

same way, your wireless connection and performance will degrade somewhat as the

distance between your wireless router and connected devices increases. This may or may not

be noticeable to you. As you move farther from your wireless router, connection speed may

decrease.

Factors that can weaken signals simply by getting in the way of your network’s radio waves

are metal appliances, obstructions, and walls.

Troubleshooting

If you have concerns about your network’s performance that might be related to range or

obstruction factors, try moving the computer to a position between five and 10 feet from the

wireless router in order to see if distance is the problem. If difficulties persist refer to the user

guide that accompanied your wireless router.

Note: While some of the items listed below can affect network performance, they will not

prohibit your wireless network from functioning. If you are concerned that your network

is not operating at its maximum effectiveness, this checklist may help.

You cannot connect to the Internet wirelessly

If you are unable to connect to the Internet from a wireless computer, check the following

items:

• Look at the lights on your wireless router. If you’re using a Dynex Wireless Router, the

lights should be as follows:

• The Power light should be on.

• The Connected light should be on, and not blinking.

• The WAN light should be either on or blinking.

If you are not using a Dynex Wireless Router, consult that router manufacturer’s user

guide.

• Open your Wireless Networking Utility (WNU) software by clicking on the icon in the

system tray at the bottom right corner of the screen. The tray icon should look like this

(the icon may be red or green):

• The window that opens should have a list of Available Networks. Available networks

are wireless networks to which you can connect.

If you are using a Dynex 802.11g (54g) router, Dynex54g is the default name.

If you are NOT using a Dynex router, consult your router manufacturer’s user guide for

the default name.

The name of your wireless network appears in the Available Networks list.

If the correct network name is listed in the Available Networks list, follow these steps to

connect wirelessly:

1 Click on the correct network name in the Available Networks list.

2 If the network has security (encryption) enabled, you need to enter the network key.

For more information regarding security, see “Securing your Wi-Fi® Network” on

page 12.

3 Within a few seconds, the tray icon in the lower right corner of your screen should turn

green, indicating a successful connection to the network.

Troubleshooting

The name of your wireless network DOES NOT appear in the list of

Available Networks.

If the correct network name is not listed under “Available Networks” in the WNU, try the

following troubleshooting steps:

1 Temporarily move the computer, if possible, to 5 to 10 feet away from the wireless

router. Close the WNU and reopen it. If the correct network name now appears under

Available Networks, you may have a range or interference problem. See the

suggestions listed in “Placement of your wireless networking hardware for optimal

performance” on page 19.

2 Using a computer that is connected to the wireless router through a network cable (as

opposed to wirelessly), make sure that Broadcast SSID is enabled. This setting is

found on the router’s wireless Channel and SSID configuration page. For detailed

instructions on accessing this page and changing settings, see your wireless router’s

User Manual.

The installation CD does not start WNU

If the installation CD does not start the WNU automatically, it could be that the computer is

running other applications that are interfering with the CD drive.

To start the installation manually:

1 If the WNU screen does not appear within 15-20 seconds, open up your CD drive by

double-clicking on the My Computer icon.

2 Double-click on the CD drive that the installation CD has been placed in to start the

installation.

3 Double-click the Files folder, then double-click the Setup.exe icon.

The Power LED does not come on. The card is not working

If the LED indicators are not ON, the problem may be that the card is not connected or is not

installed correctly.

Make sure that the card is plugged firmly into the PCI slot of your computer. Check to see that

the drivers for the card have been installed. Right-click on the My Computer icon on your

notebook. Choose Properties and navigate to the Device Manager and see if your card is

listed without any errors.

The Link LED is blinking slowly and you cannot connect to

a wireless network or the Internet

If your card appears to be functioning correctly, but you cannot connect to a network or you

have a red wireless icon at the bottom of your screen, the problem may be that there is a

mismatch between the network name (SSID) settings in your wireless network properties.

Check the SSID settings to see if they match. The SSID is case-sensitive and the spelling on

each computer must be exactly the same in order for the card to connect to the wireless

router.

Note: To check the SSID settings or look for an available network, double-click the Signal

Indicator icon to bring up the Wireless Networks screen. Click Add if you do not see the

network you are trying to connect to and type in the SSID.

Troubleshooting

For more information about setting up an SSID, refer to your router manufacturer’s user

guide.

The Link LED is solid, but you cannot connect to the

Internet

If you have a signal but cannot get online or obtain an IP address, the problem may be that

there is a mismatch between the encryption key settings in your computer and wireless

router.

Check the WEP key settings to see if they match. The key is case-sensitive and the spelling on

each computer and wireless router must be exactly the same in order for the card to connect

to the router. For more information about encryption, see “Securing your Wi-Fi® Network” on

page 12.

The data transfer is sometimes slow or signal strength is

poor

Wireless technology is radio-based, which means connectivity and the throughput

performance between devices decreases when the distance between devices increases.

Other factors that cause signal degradation are obstructions such as walls and metal

appliances. As a result, the typical indoor range of your wireless devices will be between 100

to 200 feet. Note also that connection speed may decrease as you move farther from the

wireless router.

In order to determine if wireless issues are related to range, we suggest temporarily moving

the computer, if possible, to five to 10 feet away from the wireless router. See “Placement of

your wireless networking hardware for optimal performance” on page 19.

Changing the wireless channel - Depending on local wireless traffic and interference,

switching the wireless channel of your network can improve performance and reliability. The

default channel the router is shipped with is channel 11. You may choose from several other

channels depending on your region; see your router's (or access point's) user manual for

instructions on how to choose other channels.

Limiting the wireless transmit rate - Limiting the wireless transmit rate can help

improve the maximum wireless range, and connection stability. Most wireless cards have the

ability to limit the transmission rate. To change this property, click Start, Control Panel,

Network Connections, then double-click your card's connection. In the Properties dialog,

select the Configure button on the General tab (Windows 98 users will have to select the

Wireless Card in the list box and then click Properties), then choose the Advanced tab and

select the rate property. Wireless client cards are usually set to automatically adjust the

wireless transmit rate for you, but doing so can cause periodic disconnects when the wireless

signal is too weak; as a rule, slower transmission rates are more stable. Experiment with

different connection rates until you find the best one for your environment; note that all

available transmission rates should be acceptable for browsing the Internet. For more

assistance, see your wireless card's literature.

Troubleshooting

Why are there two wireless utilities in your system tray?

Which one should you use?

There are several features and advantages to using the WNU over the Windows XP Wireless

Zero Configuration utility. We offer a site survey, detailed link information, and adapter

diagnosis.

It’s essential to know which utility is managing your adapter. We recommend using the WNU.

To use the WNU:

1 Right-click on the network status icon in the system tray and select View Available

Wireless Networks.

2 Click the Advanced button in the lower left-hand corner of the Available Wireless

Networks window.

3 From the Advanced tab, uncheck Use Windows to configure my wireless

network. After the box is unchecked, click OK to close the window.

You are now using the WNU to configure the card.

The card does not work or the connection is unstable

when the computer has a second built-in wireless network

card (such as a mini PCI or Intel® Centrino™)

This condition occurs if your computer has a built-in wireless card while your Wireless Card is

also active. This happens because Windows must now handle two active wireless

connections.

You need to disable the built-in wireless card from your computer under Network Adapters

in the Device Manager.

Card does not work or the connection is slow when

computer has a built-in wired Ethernet card

This condition occurs if your computer has an active Ethernet card while your wireless card is

also active. This happens because Windows must now handle two active network

connections. You need to disable the Ethernet card from your computer under Network

Adapters in the Device Manager.

WEP

WEP est un protocole courant qui fournit une sécurité à tous les produits sans fil compatibles

Wi-Fi. WEP donne aux réseaux sans fil un niveau de protection équivalent à celui d'un réseau

câblé comparable.

Clés de cryptage WEP — Après avoir sélectionné le mode de cryptage WEP 64 bits ou

128 bits, il est essentiel de générer une clé de cryptage. Si la clé de cryptage n'est pas la

même dans tout le réseau sans fil, les dispositifs du réseau sans fil ne pourront pas

communiquer les uns avec les autres. La clé peut être saisie en tapant manuellement la clé

hexadécimale, ou en tapant un mot de passe dans le champ « Passphrase » (Mot de passe) et

en cliquant sur« Generate » (Générer) pour créer une clé. Une clé hexadécimale est une

combinaison de chiffres et de lettres de A à F et de 0 à 9. Pour le mode WEP 64 bits, il faut

entrer 10 caractères hexadécimaux. Pour le mode WEP 128 bits, il faut entrer 26 caractères

hexadécimaux.

Par exemple :

AF 0F 4B C3 D4 = clé pour WEP 64bits

C3 03 0F AF 0F 4B B2 C3 D4 4B C3 D4 E7 = clé pour WEP 128 bits

Le mot de passe WEP n'est PAS la même chose que la clé WEP. La carte utilise ce mot de passe

pour générer les clés WEP, mais différents fabricants de matériel peuvent avoir différentes

méthodes pour générer les clés. Si le réseau comporte des équipements de différentes

marques, le plus simple est d'utiliser la clé WEP hexadécimale du routeur sans fil et de

l'entrer manuellement dans le tableau des clés WEP hexadécimales de la fenêtre de

configuration de la carte.

WPA

WPA est une nouvelle norme Wi-Fi qui apporte des améliorations aux caractéristiques de

sécurité de WEP. Pour utiliser la sécurité WPA, les pilotes et le logiciel des appareils sans fil

doivent être mis à niveau pour en assurer la prise en charge. Ces mises à niveau se trouvent

sur le site Web du fournisseur des appareils sans fil. Il existe trois types de sécurité WPA :

WPA-PSK (pas de serveur), WPA (avec serveur RADIUS) et WPA2.

WPA-PSK (pas de serveur) utilise en tant que clé de réseau ce que l'on appelle une clé

partagée. Une clé de réseau est un mot de passe qui comporte de 8 à 63 caractères. Cela peut

être une combinaison de lettres, de chiffres ou de caractères. Chaque client utilise la même

clé de réseau pour accéder au réseau. Généralement, il s'agit du mode utilisé dans un

environnement familial.

WPA (avec serveur RADIUS) est un système dans lequel un serveur RADIUS distribue

automatiquement la clé du réseau aux clients. Ceci se trouve généralement dans un

environnement professionnel.

WPA2 utilise AES (Advanced Encryption Standard) pour le cryptage des données, offrant ainsi

une sécurité bien supérieure à WPA. WPA utilise à la fois le protocole TKIP (Temporal Key

Integrity Protocol) et AES pour le cryptage.

La plupart des produits Wi-Fi sont expédiés sans qu'aucune sécurité ne soit activée. Aussi,

une fois que le réseau fonctionne, il faut activer WEP ou WPA et vérifier que tous les

dispositifs sans fil partagent la même clé de réseau.

Installation de la carte sans fil

IMPORTANT: Il faut maintenant configurer toutes les cartes/adaptateurs réseau pour qu'ils

correspondent à ces paramètres.

Configuration de la carte sans fil G Plus pour ordinateur

portatif pour utiliser un protocole de sécurité

Le routeur sans fil devrait déjà être configuré pour utiliser WPA ou WEP. Il faudra configurer la

carte sans fil G Plus pour ordinateur portatif de manière à ce qu'elle utilise les mêmes

paramètres de sécurité.

Modification des paramètres de sécurité sans fil

L’adaptateur réseau USB sans fil G prend en charge le plus récent protocole de sécurité WPA,

ainsi que l'ancienne norme de sécurité WEP. Par défaut, la sécurité sans fil est désactivée.

L’adaptateur sans fil Dynex est équipé de la dernière norme de sécurité, appelée Wi-Fi

Protected Access 2 (WPA2

) et de l'ancienne norme de sécurité, appelée Wired Equivalent

Privacy (WEP). Elle prend également en charge la spécification Wi-Fi Protected Setup (WPS),

qui simplifie la configuration d'un réseau sans fil. WPS utilise des méthodologies familières,

comme saisir un numéro d'identification personnel (NIP) ou appuyer sur un bouton, pour

permettre de configurer automatiquement les noms des réseaux et les protocoles WPA/

WPA2 de cryptage et d'authentification des données.

Utilisation de WPS (Wi-Fi protected setup) :

• Clé de cryptage si WPS n'est pas utilisé

• Méthode du numéro d'identification personnel (NIP) : L'adaptateur sans fil génère un

NIP qui doit être entré dans le routeur.

• Méthode de configuration du bouton-poussoir (PBC) : L'adaptateur sans fil peut

également se connecter à l'aide du bouton-poussoir du logiciel.

• Méthode de configuration manuelle : Cette section indique les paramètres de sécurité

par défaut à configurer si WPS n'est pas utilisé.

WPS utilise WPA2 pour le cryptage. Il ne fournit aucune sécurité supplémentaire, mais

standardise la méthode de sécurisation du réseau sans fil. Sur l'utilitaire client, les réseaux

qui utilisent WPS sont indiqués par une icône de clé. Il est possible d'utiliser soit la méthode

PBC, soit la méthode NIP pour permettre à un dispositif d'accéder au réseau sans fil.

Pour utiliser la méthode PBC :

1 Appuyer sur le bouton WPS (situé au dos du routeur) sans le relâcher pendant trois

secondes. Entamer la procédure WPS sur l'utilitaire client au cours des deux minutes

suivantes.

2 Ouvrir le WNU et sélectionner le nom du réseau, puis cliquer sur Connect (Connecter).

Le client échange automatiquement les informations de sécurité puis est ajouté au

réseau sans fil. Il est également possible d'entamer la méthode PBS à partir du côté

client.

Pour utiliser la méthode NIP :

1 Ouvrir le WNU et sélectionner le réseau utilisant WPS, puis cliquer sur Connect

(Connecter).

2 Choisir l'option de méthode NIP, puis exécuter la procédure WPS sur le routeur. Le

client est automatiquement inclus dans le réseau sans fil en moins de deux minutes.

Installation de la carte sans fil

Pour activer la sécurité, il faut d'abord déterminer quel standard est utilisé par le routeur

(voir le guide du routeur sans fil pour les instructions concernant l'accès aux paramètres de

sécurité).

Pour accéder aux paramètres de sécurité de l'adaptateur :

1 Ouvrir le WNU.

2 Cliquer sur l'onglet My Connections (Mes connexions), puis cliquer sur la connexion à

modifier.

3 Cliquer sur Edit (Modifier), puis sur Advanced (Avancé) pour changer les paramètres.

Configuration de WEP

Pour configurer le cryptage WEP 64 bits :

1 Sélectionner OPEN (Ouvrir) dans le menu Network Authentication (Authentification de

réseau), sous l'onglet Wireless Network Properties (Propriétés du réseau sans fil)

de la page Edit information for a network (Modifier les informations pour un réseau).

2 Sélectionner WEP dans le menu Data Encryption (Cryptage de données).

3 Après avoir sélectionné le mode de cryptage WEP, entrer la clé en saisissant

manuellement la clé hexadécimale, ou saisir un mot de passe dans le champ

Passphrase (Mot de passe) et cliquer surGenerate (Générer) pour créer une clé.

Une clé hexadécimale est une combinaison de chiffres et de lettres de A à F et de 0 à 9.

Pour le mode WEP 64 bits, il faut entrer 10 caractères hexadécimaux.

Installation de la carte sans fil

Par exemple :

AF 0F 4B C3 D4 = clé pour WEP 64 bits

4 Cliquer sur Save (Enregistrer) pour terminer. Le cryptage est maintenant configuré au

niveau du routeur sans fil. Chacun des ordinateurs du réseau sans fil doit maintenant

être configuré avec les mêmes paramètres de sécurité.

Attention : Si un client sans fil (tel qu'un ordinateur équipé d'une carte sans fil) est utilisé

pour activer les paramètres de sécurité sur le routeur sans fil, la connexion sans fil sera

temporairement perdue jusqu'à l'activation de la sécurité sur le client sans fil. Enregistrer

la clé avant d'appliquer des modifications au routeur sans fil. En cas d'oubli de la clé

hexadécimale, il sera impossible au client d'accéder au routeur sans fil.

Configuration du cryptage WEP 128 bits :
