Window XP Wireless Client Example Configuration This section shows an example of how to configure a Windows XP wireless client using Windows XP’s Wireless Zero Configuration service.

NOTE

The following steps apply to a computer running Windows XP Professional Version 2002 with Service Pack 2. To configure a wireless client on other Windows platforms, see your Microsoft Windows documentation.

1. On the desktop, right-click My Network Places and select Properties. 2. In the Network Connections window, right-click on Wireless Network Connection and select Properties. 3. Select the Wireless Networks tab. This screen displays the available wireless networks and the list of preferred networks. Windows connects to the preferred networks in the order in which they appear in the list. Figure 149 Wireless Networks

4. Click the Advanced button to display the Networks to access window. ArubaOS Version 3.4.1 | User Guide

Figure 150 Networks to Access

This window determines what types of wireless networks the client can access. By default, Windows connects to any type of wireless network. Make sure that the option Computer-to-computer (ad hoc) networks only is not selected. Click Close. 5. In the Wireless Networks tab, click Add to add a wireless network. 6. Click the Association tab to enter the network properties for the SSID.

NOTE

This tab configures the authentication and encryption used between the wireless client and the Aruba usercentric network. Therefore, the settings for the SSID that you configure on the client must match the configuration for the SSID on the controller.

For an SSID using dynamic WEP, enter the following: „

Network Authentication: Open

„

Data Encryption: WEP

„

Select the option “The key is provided for me automatically”. Each client will use a dynamicallygenerated WEP key that is automatically derived during the 802.1x process.

For an SSID using WPA, enter the following: „

Network Authentication: WPA

„

Data Encryption: TKIP

For an SSID using WPA-PSK, enter the following: „

Network Authentication: WPA-PSK

„

Data Encryption: TKIP

„

Enter the preshared key.

For an SSID using WPA2, enter the following: „

Network Authentication: WPA2

„

Data Encryption: AES

For an SSID using WPA2-PSK, enter the following: „

Network Authentication: WPA2-PSK

„

Data Encryption: AES

„

Enter the preshared key

NOTE

Do not select the option “This is a computer-to-computer (ad hoc) network; wireless access points are not used”. Figure 151 shows the configuration for the SSID WLAN-01 which uses WPA network authentication with TKIP data encryption.

7. Click the Authentication tab to enter the 802.1x authentication parameters for the SSID. This tab configures the EAP type used between the wireless client and the authentication server. Configure the following, as shown in Figure 152: z

Select Enable IEEE 802.1x authentication for this network.

z

Select Protected EAP (PEAP) for the EAP type.

z

Select Authenticate as computer when computer information is available. The client will perform computer authentication when a user is not logged in.

z

Do not select Authenticate as guest when user or computer information is unavailable. The client will not attempt to authenticate as a guest.

8. Under EAP type, select Properties to display the Protected EAP Properties window. Configure the client PEAP properties, as shown in Figure 153: z

Select Validate server certificate. This instructs the client to check the validity of the server certificate from an expiration, identity, and trust perspective.

z

Select the trusted Certification Authority (CA) that can issue server certificates for the network.

z

Select Secured password (EAP-MSCHAP v2) — the PEAP “inner authentication” mechanism will be an MS-CHAPv2 password.

z

Select Enable Fast Reconnect to speed up authentication in some cases.

9. Under Select Authentication Method, click Configure to display the EAP-MSCHAPv2 Properties window. Select the option Automatically use my Windows logon name and password (and domain if any). This option specifies that the user’s Windows logon information is used for authentication to the wireless network. This option allows the same logon credentials to be used for access to the Windows domain as well as the wireless network. Figure 154 EAP MSCHAPv2 Properties
