5. Modifying a Wireless Network
5.1 Infrastructure Mode vs. Ad Hoc Mode
You can set the Wireless Network Adapter to work in either Infrastructure mode or
Ad Hoc mode.
Infrastructure Mode
In infrastructure mode, devices communicate with each other by first going through
an Access Point (AP). Wireless devices can communicate with each other or can
communicate with a wired network. When one AP is connected to wired network
and a set of wireless stations, it is referred to as a BSS (Basic Service Set).
Ad Hoc Mode
Ad-hoc mode is also called “peer-to-peer mode” or “Independent Basic Service Set
(IBSS)”. In ad hoc mode, devices communicate directly with each other without
using an Access Point (AP).
19
5.2 Modifying a Wireless Network
1. Open “WLAN a+b+g Cardbus Adapter Configuration” by double clicking the
shortcut icon on the desktop.
Note! If there’s no network name listed in the “Profile List”, click Refresh
button and double click a Network Name from Available Networks.
The chosen Network Name is listed in the Profile List.
2. From the Profile List, select one Profile and click Modify button
20
.
3. Select Profile Editor tab and edit the settings. Click OK to save the
modifications.
„
Configuration Name: This name identifies the configuration. This name
should be unique.
„
Network Name (SSID1) (SSID2) (SSID3): The name of the wireless
network. This name cannot be longer than 32 characters. If the field is
set to be “ANY” or is left blank, your computer will connect to an AP with
the best signal strength.

Appendix A: Troubleshooting
Common Problems and Solutions
This chapter provides solutions to problems that may occur during the installation and
operation of the WLAN 802.11a+b+g Cardbus. Read the descriptions below to solve
your problems.
1. My computer does not recognize the Cardbus.
• Make sure the Cardbus is properly inserted into the CardBus slot. Note that the
Cardbus can be inserted either way, but is correctly only when it is inserted so that the
“Instant Wireless” logo on the front of the Cardbus cannot be seen. If in doubt, try
inserting the Cardbus both ways. The Cardbus will slide in further when it is correct.
2. The Cardbus does not work properly.
• Reinsert the Cardbus into your notebook’s CardBus slot. A beep should be heard if
the Cardbus is properly inserted.
• For non-Windows environments, make sure that a CARDBUS card service driver is
installed on your PC.
• Open the Control Panel and click the PC Card. Check whether it has a Cardbus in
one of the sockets or not. If you find the Cardbus in one of the sockets, it means
that the Cardbus has been detected properly. If you see a yellow question mark, the
resources are in conflict.
• Right-click My Computer and select Properties. Select Device Manager and click
the Network Adapter. You will find the WLAN 802.11a+b+g Cardbus if it is
installed successfully. If you see the yellow exclamation mark, the resources are in
conflict. Click Cardbus and then click Cardbus service. You will see the status of
the Cardbus. If there is a yellow question mark please check the following:
• Make sure that your notebook has a free IRQ.
• Make sure that you have inserted the right Cardbus and installed the proper driver.
If the Cardbus does not function after attempting the above steps, remove the
Cardbus and do the following:
• Uninstall the driver software from your PC.
• Restart your PC and repeat the hardware and software installation as specified in this
User Guide.
28
3. I cannot communicate with a wired computer linked via an access point in
the infrastructure configuration.
• Make sure that the notebook PC is powered on.
• Make sure that the Cardbus is configured with the same SSID and security options
as the other computers in the infrastructure configuration.

Frequently Asked Questions
1. Can I run an application from a remote computer over the wireless network?
This will depend on whether or not the application is designed to be used over a
network. Consult the application’s user guide to determine if it supports operation
over a network.
2. Can I play computer games with other members of the wireless network?
Yes, as long as the game supports multiple players over a LAN (local area network).
Refer to the game’s user guide for more information.
3. What is Spread Spectrum?
Spread Spectrum technology is a wideband radio frequency technique developed by
the military for use in reliable, secure, mission-critical communications systems. It is
designed to trade off bandwidth efficiency for reliability, integrity, and security. In
other words, more bandwidth is consumed than in the case of narrowband
transmission, but the trade-off produces a signal that is, in effect, louder and thus
easier to detect, provided that the receiver knows the parameters of the
spread-spectrum signal being broadcast. If a receiver is not tuned to the right
frequency, a spread-spectrum signal looks like background noise. There are two main
alternatives, Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping
Spread Spectrum (FHSS).
4. What is DSSS? What is FHSS? And what are their differences?
Frequency-Hopping Spread-Spectrum (FHSS) uses a narrowband carrier that changes
frequency in a pattern that is known to both transmitter and receiver. Properly
synchronized, the net effect is to maintain a single logical channel. To an unintended
receiver, FHSS appears to be short-duration impulse noise. Direct-Sequence
Spread-Spectrum (DSSS) generates a redundant bit pattern for each bit to be
transmitted. This bit pattern is called a chip (or chipping code). The longer the chip,
the greater the probability that the original data can be recovered. Even if one or more
bits in the chip are damaged during transmission, statistical techniques embedded in
29
the radio can recover the original data without the need for retransmission. To an
unintended receiver, DSSS appears as low power wideband noise and is rejected
(ignored) by most narrowband receivers.
5. Would the information be intercepted while transmitting on air?
WLAN features two-fold protection in security. On the hardware side, as with Direct
Sequence Spread Spectrum technology, it has the inherent security feature of
scrambling. On the software side, WLAN offers the encryption function (WEP) to
enhance security and access control.
6. What is WEP?
WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 64-bit or
128-bit shared key algorithm, as described in the IEEE 802.11 standard.
7. What is infrastructure mode?
When a wireless network is set to infrastructure mode, the wireless network is
configured to communicate with a wired network through a wireless access point.
8. What is roaming?
Roaming is the ability of a portable computer user to communicate continuously
while moving freely throughout an area greater than that covered by a single access
point. Before using the roaming function, the workstation must make sure that it is the
same channel number with the access point of dedicated coverage area.
To achieve true seamless connectivity, the wireless LAN must incorporate a number
of different functions. Each node and access point, for example, must always
acknowledge receipt of each message. Each node must maintain contact with the
wireless network even when not actually transmitting data. Achieving these functions
simultaneously requires a dynamic RF networking technology that links access points
and nodes. In such a system, the user’s end node undertakes a search for the best
possible access to the system. First, it evaluates such factors as signal strength and
quality, as well as the message load currently being carried by each access point and
the distance of each access point to the wired backbone. Based on that information,
the node next selects the right access point and registers its address. Communications
between end node and host computer can then be transmitted up and down the
backbone. As the user moves on, the end node’s RF transmitter regularly checks the
system to determine whether it is in touch with the original access point or whether it
should seek a new one. When a node no longer receives acknowledgment from its
30
original access point, it undertakes a new search. Upon finding a new access point, it
then re-registers, and the communication process continues.
9. What is ISM band?
The FCC and their counterparts outside of the U.S. have set aside bandwidth for
unlicensed use in the ISM (Industrial, Scientific and Medical) band. Spectrum in the
vicinity of 2.4 GHz, in particular, is being made available worldwide. This presents a
truly revolutionary opportunity to place convenient high-speed wireless capabilities in
the hands of users around the globe.
