Chapter 4: Installing The
Presentation Player’s Setup Utility
Overview
The Presentation Player can play from any PC in your wireless network. You will
need to install this utility in each PC that will be used with the Presentation Player –
once installed, it will not need to be done again.
1. Insert the Setup CD-ROM into your CD-ROM drive. The CD’s InstallShield
Wizard should start automatically. If it does not start automatically, click the
Start button, select Run, and type d:\setup.exe (where “d” is the letter of your
CD-ROM drive) in the Open field to start the autorun program.
2. The Welcome page for the Setup Utility will appear (as shown in Figure 4-1.).
Click the Install tab to start the installation procedure and place the Setup Utility
on your current PC. Click Uninstall to begin a simple procedure for removing
the Setup Utility. Click the User Guide tab to use this User Guide. If you need
to contact Linksys for technical support, click the Contact Us tab for that infor-
mation. Click the Exit tab to close the Setup Utility.
Figure 3-3
4. Place the Player near the monitor or projector facing the presenters so the
infra red in the remote control will have access to the Player.
5
For a wireless connection, fix the direction of the antennas. Try to place it
in a position which can best cover your wireless network. Normally, the
higher you place the antenna, the better the wireless performance will be.
The antenna’s position enhances the receiving sensitivity. Both antennas
should be perpendicular to the ground and parallel to each other.

Note: If you click Cancel at any time, you will have to re-start the
installation procedure.

7. When you see this screen, the installation of the Setup Utility onto your
computer has been completed.
Chapter 5: Using The
Presentation Player’ s Web-
based Utility
The Presentation Player has been designed to function with the default settings
in the Setup Utility. However, if you’d like to change these settings, the
Presentation Player can be configured through your web browser with the Web-
Based Utility. This chapter explains how to configure the Presentation Player in
this manner.
To access the Web-based Utility, you will need the Presentation Player’s IP
Address. To find the Player’s IP Address, make sure that the Presentation Player
is connected to the projector or monitor and that both devices are powered on.
The IP Address will be visible on the Home page, which is the first screen that
appears. Open your web browser and enter the Player’s IP Address in the
Address box. Press the Enter key and the following screen, shown in Figure 5-
1, will appear.
Figure 4-6

1. The first time you open the Web-Based Utility, enter the default password
admin into the Password field. Click the OK button. You can later set a
new password using the Password tab, as shown in Figure 5-4.

2. The Setup tab, as shown in Figure 5-2, has your available basic setup func-
tions. Most users can use the default settings, but you can change them here
if you want. Your wireless security functions are located here.
IP Address - This is the Internet Protocol Address that is assigned to the
Presentation Player. Click Obtain an IP Address Automatically or Specify
an IP Address. Choose Obtain an IP Address Automatically to allow
your Presentation Player to automatically obtain a dynamic IP address from
a DHCP server. Or, choose Specify an IP Address where you will assign
all the devices a permanent IP Address and enter the fixed IP address in the
fields provided. Then, enter the Subnet Mask into the fields provided. No
DHCP changes will take effect until the Presentation Player has been pow-
ered down and powered up again. The IP Address will only be used to
remotely configure or control the Presentation Player. You need not recon-
figure it if you are traveling to remote locations and plan to use the hand-
held remote control.
Wireless - This section contains all of your wireless settings.
• SSID - This stands for Service Set IDentifier. The SSID, also called the
Network Name, is a unique name that identifies a wireless network. In
order to connect to the Presentation Player, all of your wireless comput-
er's settings must be identical to the SSID you define here. The SSID is
case sensitive, must not exceed 30 characters, including WPG12-, but
may consist of any keyboard character. Make sure this setting is the
same for all wireless nodes communicating with the Presentation Player.
You should change the default SSID of "linksys" to a name unique to
your network.
Note: WPG12- is a permanent part of the SSID for this device. You
many enter any characters following WPG12-, but wireless PCs
must have the full SSID, including WPG12-, to communicate with
the Presentation Player. In most cases, the Control Utility will
configure this setting for you.
Figure 5-2
Firmware Version - This field displays the current firmware version of the
Presentation Player. Firmware upgrades, when available, may be down-
loaded from the Linksys web site at no charge. If you are not experiencing
any problems with the Presentation Player, you should not upgrade the
firmware. Make sure to review the release notes of any firmware version
before attempting an upgrade.
• Channel - Each Access Point and/or Presentation Player on your net-
work should be assigned a unique channel. The channel is a common
number that sets the actual frequency this particular device will use to
communicate with wireless clients. For example, TV and Radio Stations
refer to particular channels, which are actually frequencies at which
radio waves are transmitted.
System Name - This is a common name that you assign to the Presentation
Player. This field is limited to 32 characters. By default, four alphanumer-
ic characters follow the device name. These represent the last four charac-
ters of the Presentation Player's MAC (Ethernet) address. The MAC address
is printed on the bottom of the Presentation Player. Assigning unique and
memorable names is helpful, especially if you are employing multiple
Presentation devices on the same network.
If you experience poor performance, you may be encountering interfer-
ence from another wireless device. Try changing the channel, as this
may eliminate interference and increase performance. Channels 1, 6 and
11 are preferred.

• WEP - An acronym for Wired Equivalent Privacy, WEP is an encryption
method used to protect your wireless communications and prevent unau-
thorized access to the Presentation Player and/or your network.
3. The Password tab, as shown in Figure 5-4, is where you change your pass-
word and restore the factory default settings for the Presentation Player.
In order to utilize WEP encryption, click the radio button next to Enable.
Next, click the WEP Key Setting button to further define your encryption
settings, shown in Figure 5-3. All wireless devices communicating with the
Presentation Player must use the same WEP encryption settings. When
WEP is enabled, there will be a slight degradation in performance when pre-
senting from a remote wireless computer.
Figure 5-4
Choose an alphnumeric password between 4 and 16 characters and without
spaces. Enter the password into the Enter New Password field, then repeat
it in the Re-enter to Confirm field.
To clear all of the settings on the Presentation Player and restore them to the
factory default settings, click the Yes button.
Click the Apply button.
Figure 5-3
• WEP Encryption - Select 64 Bit or 128 Bit. Selecting the higher wire-
less security of 128 Bit could slow your presentation.
• Passphrase - There are two ways to create WEP Encryption keys. The
first method is to enter a Passphrase with a maximum of 16
Hexadecimal characters (letters “A”-“F” and the numbers “0”-“9”) and
click the Generate button. This will generate WEP Encryption keys
based upon that passphrase. A second method is to manually enter a 10-
digit key for 64-bit or a 26-digit key for 128-bit WEP Encryption into the
field for Key 1. Click the Apply button. Click the Clear button to erase
anything you have entered in error. Click the Close button to close the
screen.

feature allows great freedom and mobility, please consider the following
when uploading a presentation to the Presentation Player:
K Once uploaded, anyone can use the remote control to view the presen-
tation on a monitor, so take precautions if your presentation contains
sensitive or confidential material.
K The PC attempting to upload a presentation must have Microsoft
PowerPoint 97 or later installed.
K Some features, such as animation, hyperlinks, and sound will not be
available once your presentation is uploaded.
Figure 6-3
K The Presentation Player comes with 32Mb of storage for your presen-
tations. This should allow enough room for users to store several pre-
sentations. However, be sure to remove your presentations when they
are no longer needed to make room for newer files.
3. When you see the screen shown in Figure 6-4, you will choose a color setting.
Select the default True Color to have the optimum color option. If the action is
very slow or your presentation is mostly text, you may want to select Basic
Color. You will still have color and your speed will increase.
• Take Control of the Presentation Player - This feature allows you to
conveniently transfer the contents of your local PC screen to the projec-
tor or monitorthat is connected to the Player where the presentation will
be displayed. You may notice some delay in mouse and keyboard func-
tion. Such a delay is normal for this mode of operation. Only one user
at a time can control the Presentation Player. The supported display res-
olutions are 800 x 600 or 1024 x 768. Please see your Windows docu-
mentation for more information on changing your display settings.
• Give Control to Another User (Pause) - To pause your presentation or
change presenters, click this button.
• Exit (Stop) - To exit the Control utility, click this button.
If you have minimized the Control Utility during your presentation, you can
quickly restore it by double-clicking the Control Utility icon on your
Windows Status bar that is near the clock.

What is Ad-hoc?
What is a BSS ID?
An Ad-hoc wireless LAN is a group of computers, each with a WLAN adapter,
connected as an independent wireless LAN. An Ad-hoc wireless LAN is appli-
cable at a departmental scale for a branch or SOHO operation.
A specific Ad-hoc LAN is called a Basic Service Set (BSS). Computers in a
BSS must be configured with the same BSS ID.
What is an ESS ID?
What is Infrastructure?
An Infrastructure configuration could also support roaming capability for
mobile workers. More than one BSS can be configured as an Extended Service
Set (ESS). Users within an ESS could roam freely between BSSs while main-
taining a continuous connection to the wireless network stations and Wireless
Network Access Points.
An integrated wireless and wired LAN is called an Infrastructure configura-
tion. Infrastructure is applicable to enterprise scale for wireless access to a cen-
tral database, or wireless application for mobile workers.
What is Roaming?
Roaming is the ability of a portable computer user to communicate continu-
ously while moving freely throughout an area greater than that covered by a sin-
gle Wireless Network Access Point. Before using the roaming function, the
workstation must make sure that it is the same channel number as the Wireless
Network Access Point of the dedicated coverage area.
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.
To achieve true seamless connectivity, the wireless LAN must incorporate a
number of different functions. Each node and Wireless Network Access Point,
for example, must always acknowledge receipt of each message. Each node
must maintain contact with the wireless network even when not actually trans-
mitting data. Achieving these functions simultaneously requires a dynamic RF
networking technology that links Wireless Network 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 qual-
ity, as well as the message load currently being carried by each Wireless
Network Access Point and the distance of each Wireless Network Access Point
to the wired backbone. Based on that information, the node next selects the
right Wireless Network Access Point and registers its address. Communications
between end node and host computer can then be transmitted up and down the
backbone.
What is Spread Spectrum?
Spread Spectrum technology is a wideband radio frequency technique devel-
oped by the military for use in reliable, secure, mission-critical communica-
tions 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).
As the user moves on, the end node’s RF transmitter regularly checks the sys-
tem to determine whether it is in touch with the original Wireless Network
Access Point or whether it should seek a new one. When a node no longer
receives acknowledgment from its original Wireless Network Access Point, it
undertakes a new search. Upon finding a new Wireless Network Access Point,
it then re-registers, and the communication process continues.

What is DSSS? What is FHSS? And what are their differences?
Presentation Player
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 transmis-
sion, statistical techniques embedded in 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.
Appendix B: Planning Your
Wireless Network
Network Topology
A wireless LAN is exactly like a regular LAN, except that each network device in
the LAN uses wireless technology to connect to the network. Computers in a wire-
less LAN must be configured to share the same radio channel.
Wireless components provides LAN access for wireless network devices. An inte-
grated wireless and wired LAN is called an Infrastructure configuration. A group
of wireless users and an access point compose a Basic Service Set (BSS). Each
PC equipped with a wireless adapter in a BSS can talk to any computer in a wired
LAN infrastructure.
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 fea-
ture of scrambling. On the software side, the WLAN series offers the encryp-
tion function (WEP) to enhance security and access control. Users can set it up
depending upon their needs.
An infrastructure configuration extends the accessibility of a wireless user to a
wired LAN, and doubles the effective wireless transmission range for wireless
PCs. Since the access point is able to forward data within its BSS, the effective
transmission range in an infrastructure LAN is doubled.
Can Instant Wireless products support file and printer sharing?
Instant Wireless products perform the same function as LAN products.
Therefore, Instant Wireless products can work with NetWare, Windows
NT/2000, or other LAN operating systems to support printer or file sharing.
The use of a unique ID in a Basic Service Set is essential.
The Wireless LAN Infrastructure configuration is appropriate for enterprise-scale
wireless access to a central database, or as a wireless application for mobile users.
I am using 802.11b-compliant wireless equipment but still cannot connect
to my wireless network.
Verify that you are using the same IP domain as that of your wireless network.
Roaming
Infrastructure mode also supports roaming capabilities for mobile users. More
than one BSS can be configured as an Extended Service Set (ESS). This continu-
ous network allows users to roam freely within an ESS. All wireless PCs within
one Extended Service Set must be configured with the same SSID.
Selecting a feasible radio channel and optimum access point position is recom-
mended. Proper access point positioning combined with a clear radio signal will
greatly enhance performance.

Ad-hoc versus Infrastructure Mode
Appendix C: Upgrading the
Presentation Player’ s Firmware
Unlike wired networks, wireless networks have two different modes in which
they may be set up: Infrastructure and Ad-hoc. Choosing between these two
modes depends on whether or not the wireless network needs to share data or
peripherals with a wired network or not.
The Presentation Player functions with the use of firmware, programming writ-
ten in the unit’s internal memory. It is this firmware that enables the
Presentation Player to function and makes it easy to use.
If the computers on the wireless network need to be accessible by a wired network
or need to share a peripheral, such as a printer, with the wired network computers,
the wireless network should be set up in the Infrastructure mode, as shown in
Figure A-1. The basis of Infrastructure mode centers around an access point,
which serves as the main point of communications in a wireless network. Access
points transmit data to PCs equipped with wireless network card, which can
roam within a certain

If the wireless network is relatively small and needs to share resources only
with the other computers on the wireless network, then the Ad-hoc mode can
be used, as shown in Figure A-2. Ad-hoc mode allows computers equipped
with wireless transmitters and receivers to communicate directly with each
other, eliminating the need for an access point. The drawback of the Ad-hoc
mode is that wireless-equipped computers are not able to communicate with
computers on a wired network. In addition, communication between the wire-
less-equipped com-
puters is limited by the
distance and interfer-
ence directly between
them.

Driver - A workstation software module that provides an interface between a
network interface card and the upper-layer protocol software running in the
computer; it is designed for a specific NIC, and is installed during the initial
installation of a network-compatible client operating system.
Appendix D: Glossary
Adapter - Printed circuit board that plugs into a PC to add to capabilities or
connectivity to a PC. In a networked environment, a network interface card
(NIC) is the typical adapter that allows the PC to connect to the intranet and/or
Internet.
DSSS (Direct-Sequence Spread Spectrum) - DSSS generates a redundant bit
pattern for all data transmitted. This bit pattern is called a chip (or chipping
code). Even if one or more bits in the chip are damaged during transmission,
statistical techniques embedded in the receiver 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. However, to an intended receiver (i.e. another wireless LAN end-
point), the DSSS signal is recognized as the only valid signal, and interference
is inherently rejected (ignored).
Ad-hoc Network - An ad-hoc network is a group of computers, each with a
wireless adapter, connected as an independent 802.11 wireless LAN. Ad-hoc
wireless computers operate on a peer-to-peer basis, communicating directly
with each other without the use of an access point. Ad-hoc mode is also
referred to as an Independent Basic Service Set (IBSS) or as peer-to-peer
mode, and is useful at a departmental scale or SOHO operation.
Encryption - A security method that applies a specific algorithm to data in
order to alter the data's appearance and prevent other devices from reading the
information.
Backbone - The part of a network that connects most of the systems and net-
works together and handles the most data.
Bandwidth - The transmission capacity of a given facility, in terms of how
much data the facility can transmit in a fixed amount of time; expressed in bits
per second (bps).
ESS (Extended Service Set) - A set of more than two or more BSSs (multiple
access points) forming a single network.
Ethernet - IEEE standard network protocol that specifies how data is placed
on and retrieved from a common transmission medium. Has a transfer rate of
10 Mbps. Forms the underlying transport vehicle used by several upper-level
protocols, including TCP/IP and XNS.
Bit - A binary digit. The value - 0 or 1-used in the binary numbering system.
Also, the smallest form of data.
BSS (Basic Service Set) - An infrastructure network connecting wireless
devices to a wired network using a single access point.
FHSS (Frequency Hopping Spread Spectrum) - FHSS continuously changes
(hops) the carrier frequency of a conventional carrier several times per second
according to a pseudo-random set of channels. Because a fixed frequency is not
used, and only the transmitter and receiver know the hop patterns, interception
of FHSS is extremely difficult.
CSMA/CA (Carrier Sense Multiple Access/Collision Avoidance) - In local
area networking, this is the CSMA technique that combines slotted time-divi-
sion multiplexing with carrier sense multiple access/collision detection
(CSMA/CD) to avoid having collisions occur a second time.
Firmware - Code that is written onto read-only memory (ROM) or program-
mable read-only memory (PROM). Once firmware has been written onto the
ROM or PROM, it is retained even when the device is turned off.
CTS (Clear To Send) - An RS-232 signal sent from the receiving station to the
transmitting station that indicates it is ready to accept data.
Database - A database is a collection of data that is organized so that its con-
tents can easily be accessed, managed, and updated.
Fragmentation - Breaking data into smaller units when transmitting over a net-
work medium that cannot support the original size of the data.
Download - To receive a file transmitted over a network. In a communications
session, download means receive, upload means transmit.
Gateway - A device that interconnects networks with different, incompatible
communications protocols.

Hardware - Hardware is the physical aspect of computers, telecommunica-
tions, and other information technology devices. The term arose as a way to dis-
tinguish the "box" and the electronic circuitry and components of a computer
from the program you put in it to make it do things. The program came to be
known as the software.
Network - A system that transmits any combination of voice, video and/or data
between users.
Node - A network junction or connection point, typically a computer or work
station.
Hop - The link between two network nodes.
Port - A pathway into and out of the computer or a network device. For exam-
ple, the serial and parallel ports on a personal computer are external sockets for
plugging in communications lines, modems and printers.
IEEE (The Institute of Electrical and Electronics Engineers) - The IEEE
describes itself as "the world's largest technical professional society, promoting
the development and application of electrotechnology and allied sciences for
the benefit of humanity, the advancement of the profession, and the well-being
of our members."
Roaming - In an infrastructure mode wireless network, this refers to the abili-
ty to move out of one access point's range and into another and transparently
reassociate and reauthenticate to the new access point. This reassociation and
reauthentication should occur without user intervention and ideally without
interruption to network connectivity. A typical scenario would be a location
with multiple access points, where users can physically relocate from one area
to another and easily maintain connectivity.
The IEEE fosters the development of standards that often become national and
international standards. The organization publishes a number of journals, has
many local chapters, and several large societies in special areas, such as the
IEEE Computer Society.

Infrastructure Network - An infrastructure network is a group of computers
or other devices, each with a wireless adapter, connected as an 802.11 wireless
LAN. In infrastructure mode, the wireless devices communicate with each
other and to a wired network by first going through an access point. An infra-
structure wireless network connected to a wired network is referred to as a
Basic Service Set (BSS). A set of two or more BSS in a single network is
