The ESSID is a unique ID given to the Access Point. Wireless clients associating
to Access Points must have the same ESSID. The default value Auto Detect
means when the Wireless LAN Compact Flash Card starts to work, it will associate
with any Access Point that gives the fastest response. You may also enter a
specific ESSID (Access Point) you desire to connect with. It is recommended
you specify an ESSID for your Wireless LAN Compact Flash Card. This will
prevent your computer from unintentionally connecting to a different wireless
network.

-9-

Network Type

To connect your wireless station to a local network infrastructure as described in

Appendix A “ Network Configuration” on page 18, set the station operation
mode to Infrastructure (with Access Point, default setting). In case you do
not wish to connect to a network infrastructure, but prefer to setup a small wireless
workgroup (without Access Point) also described on page 18, you can enable the

Ad-Hoc (only compatible with the same series wireless PC Card) or 802.11
Ad-Hoc tick box. When the Ad-Hoc mode is selected, be sure to set your

wireless stations with the same channel. To use the 802.11 Ad-Hoc mode, the
same channel and ESSID among wireless stations are required.

Power Saving Mode

The Power Saving Mode option is designed to conserve battery life of you
computer. Selecting the “Enable” button activates the Power Save mode and your
SMC2642W 11Mbps Wireless Compact Flash Card will go into sleep mode to
minimize power consumption.

NOTE: When power saving mode is enabled, the Access Points you use need to

support power saving as well so that the communication can be
established.

TX Rate

The 11Mbps Wireless Compact Flash Card provides various data rate options for
you to select. Data rates options include Fully Auto, Fixed 1Mb/s, Fixed
2Mb/s, Auto Select 1M or 2M, Fixed 5.5Mb/s, and Fixed 11Mb/s . In most
networking scenarios, you will see that the factory-set default “Fully Auto” will
prove the most efficient. This setting will allow your 11Mbps Wireless LAN
Compact Flash Card to operate at the maximum data rate. When the
communications quality drops below a certain level, the Wireless LAN Compact
Flash Card will automatically switch to a lower data rate. Transmission at lower
data speed is usually more reliable. However, when the communications quality
improves again, the Wireless LAN Compact Flash Card will gradually increase the
data rate again, until it has reached the highest available transmit rate.

-10-

Link

Similar to the TCP/IP Ping Command, this tool allows you to monitor
point-to-point data transmission quality between two stations. By entering the IP
address of another station and setting the timeout and packet size, you may check
whether or not communication has been established successfully.

-11-

Security

To prevent unauthorized wireless stations from accessing data transmitted over the
network, the SMC2642W 11Mbps Wireless Compact Flash Card offers highly
secure data encryption, known as WEP (Wired Equivalent Privacy). If you desire
to use WEP encryption to secure your data, please select the Enable check box
and set the following values.

64-Bit – Requires wireless stations to use data encryption with 64-Bit algorithm

when communicating with the Access Point.
128-Bit – Requires wireless stations to use data encryption with 128-Bit algorithm

when communicating with the Access Point
WEP Key Type offers two key value options: Character (Char.) and

Hexadecimal numbers (Hex.). Moreover, you may choose the Authentication
Type, either Open System or Shared Key for authentication among wireless
devices. You may identify up to 4 different encryption keys and select one of
them to encrypt your transmission data. The key value of your choice may either
be:

Caveat

n Due to WinCE's nature of the first application at power-on resuming to that at

power-off, if you are stuck at the utility program, you may use the PDA's reset
button to terminate it. And then activate it again when needed.

n Sometimes, your wireless connection to AP may disconnect for any reason.

You can reset and force a connection request by going to utility program, then
select "Configuration", check parameters, then select "Apply" to force a
re-scan.

n If your device roams to a new AP which is in a different subnet, you may need

to remove and re-insert the Wireless LAN Compact Flash Card to force an
execution of "release and renew" of an re-assignment of IP address in a DHCP
Access Point environment.

are usually more reliable. However, when the communications quality improves
again, the SMC2642W 11Mbps Wireless CF Card will gradually increase the data
rate again , until it reaches the highest available transmit rate.

WEP

To prevent unauthorized wireless stations from accessing data transmitted over the
network, the WLAN Utility offers highly secure data encryption known as WEP,
which makes your data transmission more secure. To activate the WEP
Encryption, check the WEP Enabled check box. An Encryption window will
then appear. The instructions are as follows:

Ø Pull down the Encryption (WEP) menu and select either 64bit or 128bit

encryption method.

Ø Specify the encryption keys. There are two methods to set the WEP keys, as

described below:

Create Encryption Keys by Using a Passphrase

Users can just input the Passphrase. Then users need to define the Default Key
and press OK and the 4 keys will be generated for 64-Bit WEP. For 128-Bit
WEP, there will only be 1 key generated after entering the Passphrase.

Create Encryption Keys Using a Passphrase (128bit)

Create Encryption Keys Manually

You can also create encryption keys manually by clicking the Create Keys
Manually check box. For 64bit encryption, you must enter exactly 10

hexadecimal digits in the range of “A-F”, “a-f” and “0-9” (e.g. 11AA22BB33)
in each of the four key fields; for 128bit encryption, you need to enter exactly

26 hexadecimal digits in the range of “A-F”, “a-f” and “0-9” (e.g.
00112233445566778899AABBCC). Then click the Apply button to create
your encryption keys.

Loop Back:

The Loop Back tool helps you examine point-to-point data transmission
quality between your 11Mbps Wireless CF Card and any workstation on the
network. By entering the IP address of the remote station, set ping interval
and packet size, you may know whether communication has been made
successfully or not. Additionally, if you use the infrastructure wireless LAN
configuration, you may run the loopback test by clicking the Loop back button
to verify the communication quality between your wireless station and Access
Point.

AP Browser:

By clicking the Rescan button, the AP Browser can display all the Access
Points around the working environment. Besides showing the ESSID of each
Access Point, it also displays BSSID, Channel, Signal, Quality and Supported
Rates. To join any of the displayed Access Point, highlight the Access Point
you desire to connect and then click the Join BSS or Join ESS button to join
the group.

Site Survey:

When the Site Survey screen is displayed, the channel quality of all 14 radio
channels will be displayed. These channel quality measurements are shown on
each gauge for the 14 radio channels. The blue bar indicated the channel
quality is clear and good. The higher the blue bar is, the better quality you
have (i.e., less interference). The yellow bar indicates the channel quality is fair
and the red bar indicates the channel is busy or having severe interference.

Appendix A. Network Configuration

The 11Mbps Wireless LAN products support the same network configuration
options of the legacy Ethernet LANs as defined by IEEE 802 standard committee.

The 11Mbps Wireless LAN products can be configured as:

u Ad-Hoc for departmental or SOHO LANs
u Infrastructure for enterprise LANs
u LAN-Interconnection for point-to-point link as a campus backbone.

A-1 Network Topology

u Ad-Hoc

Fig An Example of Ad-Hoc Wireless LAN

An Ad-Hoc wireless LAN is a group of computers, each equipped with one
wireless adapter, connected as an independent wireless LAN. Computers in a
specific Ad -Hoc wireless LAN must be configured at the same radio channel.

Ad-Hoc wireless LAN is applicable at a departmental scale for a branch or SOHO
operation.

u Infrastructure

Fig An Example of Infrastructure Wireless LAN

The 11Mbps Wireless LAN devices provide access to a wired LAN for wireless

workstations. An integrated wireless and wired LAN is called an Infrastructure
configuration. A group of wireless LAN PC users and an Access Point construct
a Basic Service Set (BSS). Each wireless-equipped PC in this BSS can talk to
any computer in the wired LAN infrastructure via the Access Point.

Infrastructure configuration will extend the acces sibility of a wireless station to the
wired LAN. Multiple Access Points will allow roaming and it will increase the
transmission range. The Access Point is also able to forward data within its BSS.
The effective transmission range in an infrastructure LAN is doubled.
