Installing The 802.11b Radio
6.1 Installing The 802.11b Radio
The WORKABOUT PRO operates with an 802.11b Direct Sequence Spread
Spectrum radio. The CF (Compact Flash) card is easily installed in the unit.
• To begin, remove the battery pack. If your unit is using AC power,
disconnect it.
• Remove the stylus from the end-cap before removing the end-cap itself.
• Remove the end-cap at the top of the WORKABOUT PRO – unscrew the
four Philips head screws from the cap.

Install the battery, and replace the backplate.
Slide the SW1401 switch to the right to turn power back on.
Replace the end-cap, and tighten the four Philips screws to secure
the end-cap.
Important:
The WORKABOUT PRO does not support hot swapping cards.
All power sources must be switched off before inserting a card
in the unit.
6.2 Connecting To A LAN Using An 802.11b Radio
Once the 802.11b radio is installed in the WORKABOUT PRO, you’ll need to take
a few steps to configure the radio.
6.2.1 Configuring An IEEE 802.11b Radio
While most common 802.11b settings are configured as defaults, there are some
fields that must be completed, including the SSID of your access point and the
security methods implemented in the network (including access keys).

Chapter 6: Connecting To A LAN With 802.11b
Configuring An IEEE 802.11b Radio
Important:
If the WORKABOUT PRO radio has never been configured, the
radio settings dialogue box will open automatically when the unit
is powered on. In this case, skip to Step 4 on page 113.
To configure the 802.11b radio:
1. Tap on the Start button in the taskbar, and tap on
Settings>Network....
Figure 6.5 Network And Dial-Up Connections
Note: You can also press   to display the Start Menu.
2. Tap on the radio icon to open the 802.11b Wireless LAN Settings window – in
the sample screen this is labelled NETWLAN1.

3. Wireless Statistics Tab
When you choose the Wireless LAN icon, an 802.11b Wireless LAN Settings
window (NETWLAN1 in the sample below) is displayed.
Figure 6.7 Wireless Statistics
This tab lists your radio statistics. Tapping on the  button resets the
statistics of the last four items – Packets IN, Packets OUT, IN errors and OUT errors.
• Tap on the Wireless Information tab.
4. Wireless Information Tab
The options under this tab list existing networks to which you can
connect, and it allows you to add a new network or modify the settings
for an existing network.

Note:  button – To change the settings in an existing network,
highlight the network you want to modify, and tap the  button
to display the Wireless Properties dialogue box.
 button – To force connection to a specific, existing network,
highlight the network to which you want your unit to connect, and tap
the  button.
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 unit attempts to connect to preferred networks. This behaviour can be changed by enabling (√) ‘Automatically connect to
non-preferred networks’ in the Advanced dialogue box (page 118).
• To add a new configuration, tap the  button. A blank Wireless
Properties dialogue box is displayed.

•
Type the appropriate SSID (Service Set Identifier) in the ‘Network name
(SSID):’ text entry field at the top of this dialogue 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 PRO 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 WORKABOUT PROs must pass data through an access point – leave the checkbox
next to ‘This is an ad hoc network’ blank.
If you are using an “Ad Hoc” network – a network in which hand-held computers pass data directly to other hand-helds without an access point – tap
on the checkbox 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 dropdown encryption menu. Otherwise, leave
this field as is.
Authentication
802.11b supports two subtypes of network authentication services: Open
and Shared. 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 802.11b wireless network communications channel.
Network Key:
This text box is used to specify a 5 or 13 ASCII character sequence or an
equivalent 10 or 26 Hexadecimal digit sequence that matches the active
WEP key on the access point.

To assign a Network key, tap the stylus in the checkbox next to ‘The key is
provided automatically’ to remove the √ and disable this option.
Disable this option to
access Network Key &
Key Index fields.

Key Index:
This field is used to identify the WEP key.
• Enter a value from 1 to 4.
Enable 802.1x authentication
“802.1X” is the IEEE standard that offers additional security for local area
networks. It provides authentication for user devices attached to an Ethernet
network, whether wired or wireless. A security protocol packet such as TLS
or MD5 encapsulated in an “EAP” is used in conjunction with the “802.1x”
standard to authenticate users at the MAC layer. Available EAPs are listed
in the dropdown menu next to the ‘EAP’ option.
•
To activate “802.1X”, tap the stylus in the checkbox next to ‘Enable 802.1x
authentication’ to enable (√) it.
EAP Type (Extensible Authentication Protocol):
This dropdown menu lists the EAP types available on your system. The
items in this dropdown menu will vary depending on your network setup.
Keep in mind also that some authentication protocols require that you select
a ‘Certificate’. By selecting the Properties button, you will be able to select a
Certificate. “Certificate Assignment” on page 77 provides a website that
outlines how to create certificates for your network.
6. Saving and exiting the radio setup.
Once you have completed your configuration, tap on .

Chapter 6: Connecting To A LAN With 802.11b
Assigning An IP Address
The connection you created will be listed in the Wireless Information tab as a preferred
network. The radio will search for the SSID and will compare the WEP and
authentication information you specified. If there is a match between your
WORKABOUT PRO settings and the access point settings, the WORKABOUT
PRO will communicate on the network through the access point.
6.2.2 Assigning An IP Address
If your network is not using a DHCP server, you will need to assign an IP address.
•
In the NETWLAN1 Settings window, display the IP Information tab.
Figure 6.11 IP Information
Note: Tapping on the  button forces the WORKABOUT PRO to renew
or find a new IP address. This is useful if, for example, you are out of communication range for a longer period of time and your hand-held is
dropped from the network.
• Tap on the  button to define a static IP address.
