Wireless Information
This appendix describes how to set up your radio using Windows Wireless Zero Configuration – an alternative to the Fusion Wireless Companion.
NOTE
For details about using Fusion Wireless Companion, refer to Fusion Wireless Companion - Setting
Up the 802.11a/b/g/n on page 3-65 .
• Tap on the Fusion icon in the taskbar at the bottom of the screen to display the menu. In the Fusion
Launch
menu, tap on Options.
• Choose WLAN Management from the Options drop-down menu, and tap on Save.

• Tap on the radio button next to Windows Manages WLAN, and tap on Save and OK.
• Press and hold down the [Power] button and the [FN/BLUE] key to reset the unit.
Wireless Information Tab
This tab displays existing networks to which you can connect, and it allows you to add a new network or modify the settings for an existing network.
• Configure button: To change the settings in an existing network, highlight the network you want to modify, and tap on the Configure button to display the Wireless Properties dialog box.
• Connect button: To force connection to a specific, existing network, highlight the network to which you want the Workabout Pro4 to connect, and tap on the Connect button.

Wireless Information
This tab lists available networks — any access points that are broadcasting an SSID, and it lists preferred networks — networks that you have configured. Since access points are generally secure, they will most likely not be listed here. By default, the Workabout Pro4 attempts to connect to preferred networks. This behaviour can be changed by enabling Automatically connect to non-preferred networks in the Advanced dialog box
(see
Figure G-9 Advanced Wireless Settings ).
• To add a new configuration, tap on the Add New button. A blank Wireless Properties dialog box is displayed.

• Type the appropriate SSID (Service Set Identifier) in the Network name (SSID): dialog box. The
Network name
field can contain a maximum of 32 characters. The name assigned here is listed as a preferred network.
IMPORTANT
Keep in mind that the Workabout Pro4 will only communicate with access points that are configured with the same SSID.
• Ad Hoc And Infrastructure: If you are using an Infrastructure network — one in which the hand-helds must pass data through an access point — leave the check box next to This is an ad hoc network blank.
If you are using an Ad Hoc network — a network in which the hand-helds pass data directly to other Ad
Hoc devices without an access point — add a check mark in the check box next to This is an ad hoc
network
to enable Ad Hoc.
• Encryption: WEP (Wired-Equivalent Privacy) encryption prevents others from accidentally accessing your network. If you are not using encryption, you can choose Disabled from the drop-down encryption menu.
Otherwise, leave this field as is.
AES
(Advanced Encryption Standard) is a standard for protecting data through encryption. AES supports key sizes of 128 bits, 192 bits and 256 bits and will serve as a replacement for the Data Encryption Standard (DES), which has a key size of 56 bits. In addition to the increased security that comes with larger key sizes, the AES algorithm is a symmetrical block cipher that can encrypt (encipher) and decrypt
(decipher) information.
TKIP (Temporal Key Integrity Protocol) uses the original WEP programming but wraps additional code at the beginning and end to encapsulate and modify it. Like WEP, TKIP uses the RC4 stream encryption algorithm as its basis. The new protocol, however, encrypts each data packet with a unique encryption key, and the keys are much stronger than those of its predecessor.
• Authentication: 802.11 supports several subtypes of network authentication services: Open, Shared,
WPA,
and WPA-PSK. Under Open authentication, any wireless station can request authentication. The station that needs to authenticate with another wireless station sends an authentication management frame that contains the identity of the sending station. The receiving station then sends back a frame that indicates whether it recognizes the identity of the sending station.
Under Shared authentication, each wireless station is assumed to have received a secret shared key over a secure channel that is independent from the 802.11 wireless network communications channel.
Under WPA and WPA-PSK authentication, the use of 802.1x authentication is required. For wireless networks without a Remote Authentication Dial-In User Service (RADIUS) infrastructure, WPA supports the use of a preshared key. For wireless networks with a RADIUS infrastructure, Extensible Authentication
Protocol (EAP) and RADIUS is supported.
