Chapter 2: Planning Your
Wireless Network
Network Topology
A wireless local area network (WLAN) is exactly like a regular local area network (LAN), except that each computer in the WLAN uses a wireless device to
connect to the network. Computers in a WLAN share the same frequency
channel and SSID, which is an identification name for wireless devices.
Wireless Network Access Point
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. (See Figure 2-2.) 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 this mode is that, in AdHoc mode, wireless-equipped computers are not able to communicate with
computers on a wired network. And, of course, communication between the
wireless-equipped computers is limited by the distance and interference directly between them.
Ad-Hoc versus Infrastructure Mode
Unlike wired networks, wireless networks have two different modes in which
they may be set up: infrastructure and ad-hoc. An infrastructure configuration is a WLAN and wired LAN communicating to each other through an
access point. An ad-hoc configuration is wireless-equipped computers communicating directly with each other. 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.
Figure 2-2
If the computers on the
wireless network need to
be accessed 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 infrastructure mode.
(See Figure 2-1.) The
basis of infrastructure
mode centers around an
Figure 2-1
access point, which serves
as the main point of communications in a wireless network. Access points transmit data to PCs equipped
with wireless network cards, which can roam within a certain radial range of
the access point. Multiple access points can be arranged to work in succession
to extend the roaming range, and can be set up to communicate with your
Ethernet (wired) hardware as well.

There are two ways to reset the Access Point’s factory
defaults. Briefly press the Reset Button for approximately
ten seconds, or use the Password tab of the Access Point’s
Web-based Utility.
Important: Resetting the Access Point will erase all of your settings
(WEP Encryption, Wireless, and LAN settings, etc.) and replace
them with the factory defaults.
Instant Wireless® Series
Chapter 4: Connecting the
Wireless Network Access Point
1. Locate an optimum location for the Access Point. The best place for the
Access Point is usually at the center of your wireless network, with line of
sight to all of your mobile stations.
2. Fix the direction of the antenna. Try to place it in a position which can best
cover your wireless network. Normally, the higher you place the antenna,
the better the performance will be. The antenna’s position enhances the
receiving sensitivity. Both antennas should be perpendicular to the ground
and parallel to each other.
3. Connect the included Category 5 Ethernet network cable to the Access
Point. Then, connect the other end of the Ethernet cable to a switch or hub.
The Access Point will then be connected to your 10/100 network.
4. Connect the AC power adapter to the Access Point’s Power port. Only use
the power adapter supplied with the Access Point. Use of a different adapter
may result in product damage.
Now that the hardware installation is complete, proceed to “Chapter 5: Setting
Up the Wireless Network Access Point” for directions on how to set up the
Access Point.
Note: In order for all other wireless devices to communicate with
the Access Point, those devices must be operating in the infrastructure mode. If any wireless devices are configured in the ad-hoc
mode, they will not be recognized by the Access Point.
Wireless Network Access Point
Chapter 5: Setting Up the
Wireless Network Access Point
Have You: Connected the Access Point to a hub, switch, or router
on your wired network as shown in “Chapter 4: Connecting the
Wireless Network Access Point”?

Appendix A: Troubleshooting
This chapter provides a list of questions and answers regarding the operation of
the Access Point. Read the description below to solve your problems. If you
can’t find an answer here, check the Linksys website at www.linksys.com.
Frequently Asked Questions
Can the Access Point act as my DHCP Server?
No. The Access Point is nothing more than a wireless hub, and as such, cannot
be configured to handle DHCP capabilities.
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.
Can I play multiplayer games with other users 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.
What is the IEEE 802.11b standard?
It is one of the IEEE standards for wireless networks. The 802.11b standard
allows wireless networking hardware from different manufacturers to communicate, provided that the hardware complies with the 802.11b standard. The
802.11b standard states a maximum data transfer rate of 11Mbps and an operating frequency of 2.4GHz.
What IEEE 802.11b features are supported?
The product supports the following IEEE 802.11 functions:
•
CSMA/CA plus Acknowledge protocol
•
Multi-Channel Roaming
•
Automatic Rate Selection
•
RTS/CTS feature
•
Fragmentation
•
Power Management
What is ad-hoc mode?
When a wireless network is set to ad-hoc mode, the wireless-equipped computers are configured to communicate directly with each other. The ad-hoc
wireless network will not communicate with any wired network.
30
31
Instant Wireless® Series
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.
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 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.
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 transmitting 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 quality, 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.
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 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 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.
32
Wireless Network Access Point
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).
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 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.
Would the information be intercepted while transmitting on air?
Instant Wireless products feature 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, Instant Wireless
products offer the encryption function (WEP) to enhance security and access
control. Users can set it up depending upon their needs.
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.
What is WEP?
WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 40/64
bit shared key algorithm, as described in the IEEE 802.11 standard.
33
Instant Wireless® Series
What is a MAC Address?
The Media Access Control (MAC) address is a unique number assigned by the
manufacturer to any Ethernet networking device, such as a network adapter,
that allows the network to identify it at the hardware level. For all practical purposes, this number is usually permanent. Unlike IP addresses, which can
change every time a computer logs on to the network, the MAC address of a
device stays the same, making it a valuable identifier for the network.

Appendix B: Setting Up the TCP/ I P
Protocol
Setting Up TCP/IP in Windows
Before a computer can communicate with the Access Point, it must be configured with the TCP/IP protocol. If you know how to set up TCP/IP on your computers, do so now. Otherwise, use the guidelines below to help get TCP/IP
installed on all of the computers that need to communicate with the Access
Point. If you are unable to successfully install TCP/IP on one or more computers after following the directions, contact the manufacturer of your computer’s
network operating system for further assistance. Check with your network
administrator for your TCP/IP settings.
The directions below provide general guidelines for coming up with IP addresses and subnet masks. Check with your network administrator to see if you need
to use specific IP addresses or DHCP settings.
First, each computer on the network will require an IP address, which is a series
of numbers, separated by periods, identifying the PC on the network. To make
things simple, it is recommended you use the following numbering scheme:
192.168.1.X
In this example, X is a unique, arbitrarily assigned number from 1 to 254. Each
computer must have its own unique X number. Note: Never use 0 or 255 for X.
These numbers are reserved by TCP/IP for other uses.
For example, if you have three computers, you could number them as follows:
192.168.1.17
192.168.1.44
192.168.1.126
In this case, 17, 44, and 126 are arbitrary numbers between 1 and 254.
Each computer will also require a subnet mask, which is a numerical “filter”
that tells a computer what kinds of TCP/IP data packets to accept. If you’re not
sure which mask to use, the following mask is recommended:
255.255.255.0

Appendix C: 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 is
the typical adapter that allows the PC or server to connect to the intranet and/or
Internet.
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.

Backbone - The part of a network that connects most of the systems and networks together and handles the most data.
7. Enter an IP address for the computer, along with a Subnet mask and Default
gateway address. Then, click the OK button. If you do not have these values, consult your network administrator.
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).
8. When you’re finished, click the Close button. Restart your computer.
TCP/IP has now been successfully installed.
Beacon Interval - A beacon is a packet broadcast by the Access Point to keep
the network synchronized. A beacon includes the wireless LAN service area,
the AP address, the Broadcast destination addresses, a time stamp, Delivery
Traffic Indicator Maps, and the Traffic Indicator Message (TIM).
Bit - A binary digit. The value - 0 or 1-used in the binary numbering system.
Also, the smallest form of data.
Browser - A browser is an application program that provides a way to look at
and interact with all the information on the World Wide Web or PC. The word
“browser” seems to have originated prior to the Web as a generic term for user
interfaces that let you browse text files online.
BSS (Basic Service Set) - An infrastructure network connecting wireless
devices to a wired network using a single access point.
Buffer - A buffer is a shared or assigned memory area used by hardware
devices or program processes that operate at different speeds or with different
sets of priorities. The buffer allows each device or process to operate without
38
39
Instant Wireless® Series
being held up by the other. In order for a buffer to be effective, the size of the
buffer and the algorithms for moving data into and out of the buffer need to be
considered by the buffer designer. Like a cache, a buffer is a "midpoint holding
place” but exists not so much to accelerate the speed of an activity as to support the coordination of separate activities.
DHCP supports static addresses for computers containing Web servers that
need a permanent IP address.
CSMA/CA (Carrier Sense Multiple Access/Collision Avoidance) - In local
area networking, this is the CSMA technique that combines slotted time-division multiplexing with carrier sense multiple access/collision detection
(CSMA/CD) to avoid having collisions occur a second time. This works best if
the time allocated is short compared to packet length and if the number of situations is small.
Driver - A workstation or server software module that provides an interface
between a device and the upper-layer protocol software running in the computer; it is designed for a specific device, and is installed during the initial installation of a network-compatible client or server operating system.
CSMA/CD (Carrier Sense Multiple Access/Collision Detection) - The LAN
access method used in Ethernet. When a device wants to gain access to the network, it checks to see if the network is quiet (senses the carrier). If it is not, it
waits a random amount of time before retrying. If the network is quiet and two
devices access the line at exactly the same time, their signals collide. When the
collision is detected, they both back off and each wait a random amount of time
before retrying.
Database - A database is a collection of data that is organized so that its contents can easily be accessed, managed, and updated.
DHCP (Dynamic Host Configuration Protocol) - A protocol that lets network
administrators manage centrally and automate the assignment of Internet
Protocol (IP) addresses in an organization's network. Using the Internet's set of
protocol (TCP/IP), each machine that can connect to the Internet needs a
unique IP address. When an organization sets up its computer users with a connection to the Internet, an IP address must be assigned to each machine.
Without DHCP, the IP address must be entered manually at each computer and,
if computers move to another location in another part of the network, a new IP
address must be entered. DHCP lets a network administrator supervise and distribute IP addresses from a central point and automatically sends a new IP
address when a computer is plugged into a different place in the network.
DHCP uses the concept of a “lease” or amount of time that a given IP address
will be valid for a computer. The lease time can vary depending on how long a
user is likely to require the Internet connection at a particular location. It's especially useful in education and other environments where users change frequently. Using very short leases, DHCP can dynamically reconfigure networks
in which there are more computers than there are available IP addresses.

Wireless Network Access Point
Download - To receive a file transmitted over a network. In a communications
session, download means receive, upload means transmit.
DSSS (Direct-Sequence Spread-Spectrum) - DSSS generates a redundant bit
pattern for all transmitted data. 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 endpoint), the DSSS signal is recognized as the only valid signal, and interference
is inherently rejected (ignored).
DTIM (Delivery Traffic Indication Message) - A DTIM field is a countdown
field informing clients of the next window for listening to broadcast and multicast messages. When the AP has buffered broadcast or multicast messages for
associated clients, it sends the next DTIM with a DTIM Interval value. AP
Clients hear the beacons and awaken to receive the broadcast and multicast
messages.
Dynamic IP Address - An IP address that is automatically assigned to a client
station in a TCP/IP network, typically by a DHCP server. Network devices that
serve multiple users, such as servers and printers, are usually assigned static IP
addresses.
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.
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
41
Instant Wireless® Series
10 Mbps. Forms the underlying transport vehicle used by several upper-level
protocols, including TCP/IP and XNS.
FHSS (Frequency Hopping Spread Spectrum) - FHSS continuously changes
the center frequency of a conventional carrier several times per second according to a pseudo-random set of channels, while chirp spread spectrum changes
the carrier frequency. Because a fixed frequency is not used, illegal monitoring
of spread spectrum signals is extremely difficult, if not downright impossible
depending on the particular method.
Firmware - Code that is written onto read-only memory (ROM) or programmable read-only memory (PROM). Once firmware has been written onto the
ROM or PROM, it is retained even when the device is turned off.
Fragmentation - Breaking a packet into smaller units when transmitting over
a network medium that cannot support the original size of the packet.
Gateway - A device that interconnects networks with different, incompatible
communications protocols.
Hardware - Hardware is the physical aspect of computers, telecommunications, and other information technology devices. The term arose as a way to distinguish 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.
Hub - The device that serves as the central location for attaching wires from
workstations. Can be passive, where there is no amplification of the signals; or
active, where the hubs are used like repeaters to provide an extension of the
cable that connects to a workstation.
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.”
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.

Wireless Network Access Point
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 infrastructure 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
referred to as an Extended Service Set (ESS). Infrastructure mode is useful at
a corporation scale, or when it is necessary to connect the wired and wireless
networks.
IP Address - In the most widely installed level of the Internet Protocol
(Internet Protocol) today, an IP address is a 32-binary digit number that identifies each sender or receiver of information that is sent in packet across the
Internet. When you request an HTML page or send e-mail, the Internet
Protocol part of TCP/IP includes your IP address in the message (actually, in
each of the packets if more than one is required) and sends it to the IP address
that is obtained by looking up the domain name in the Uniform Resource
Locator you requested or in the e-mail address you're sending a note to. At the
other end, the recipient can see the IP address of the Web page requestor or the
e-mail sender and can respond by sending another message using the IP address
it received.
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.
LAN - A local area network (LAN) is a group of computers and associated
devices that share a common communications line and typically share the
resources of a single processor or server within a small geographic area (for
example, within an office building).
MAC (Media Access Control) Address - A unique number assigned by the
manufacturer to any Ethernet networking device, such as a network adapter,
that allows the network to identify it at the hardware level.
Mbps (MegaBits Per Second) - One million bits per second; unit of measurement for data transmission.
Multicasting - Sending data to a group of nodes instead of a single destination.
43
Instant Wireless® Series
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.
Wireless Network Access Point
Software - Instructions for the computer. A series of instructions that performs
a particular task is called a “program.” The two major categories of software are
“system software” and “application software.” System software is made up of
control programs such as the operating system and database management system (DBMS). Application software is any program that processes data for the
user.
Packet - A unit of data routed between an origin and a destination in a network.
Passphrase - Used much like a password, a passphrase simplifies the WEP
encryption process by automatically generating the WEP encryption keys for
Linksys products.
PC Card - A credit-card sized removable module that contains memory, I/O,
or a hard disk.
Port - A pathway into and out of the computer or a network device such as a
switch or router. For example, the serial and parallel ports on a personal computer are external sockets for plugging in communications lines, modems and
printers.
RJ-45 (Registered Jack-45) - A connector similar to a telephone connector that
holds up to eight wires, used for connecting Ethernet devices.
Roaming - In an infrastructure mode wireless network, this refers to the ability 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.
Router - Protocol-dependent device that connects subnetworks together.
Routers are useful in breaking down a very large network into smaller subnetworks; they introduce longer delays and typically have much lower throughput
rates than bridges.
RTS (Request To Send) - An RS-232 signal sent from the transmitting station
to the receiving station requesting permission to transmit.
Server - Any computer whose function in a network is to provide user access
to files, printing, communications, and other services.
44
A common misconception is that software is data. It is not. Software tells the
hardware how to process the data.
SOHO (Small Office/Home Office) - Market segment of professionals who
work at home or in small offices.
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).
SSID (Service Set Identifier) - A unique name shared among all points in a
wireless network. The SSID must be identical for each point in the wireless
network and is case-sensitive. Also known as “ESSID.”
Static IP Address - A permanent IP address that is assigned to a node in an IP
or a TCP/IP network.
Subnet Mask - The method used for splitting IP networks into a series of subgroups, or subnets. The mask is a binary pattern that is matched up with the IP
address to turn part of the host ID address field into a field for subnets.
Switch - 1. A data switch connects computing devices to host computers,
allowing a large number of devices to share a limited number of ports. 2. A
device for making, breaking, or changing the connections in an electrical circuit.
TCP (Transmission Control Protocol) - A method (protocol) used along with
the IP (Internet Protocol) to send data in the form of message units (datagram)
45
Instant Wireless® Series
between network devices over a LAN or WAN. While IP takes care of handling
the actual delivery of the data (routing), TCP takes care of keeping track of the
individual units of data (called packets) that a message is divided into for efficient delivery over the network. TCP is known as a "connection oriented" protocol due to requiring the receiver of a packet to return an acknowledgment of
receipt to the sender of the packet resulting in transmission control.
TCP/IP (Transmission Control Protocol/Internet Protocol) - The basic communication language or set of protocols for communications over a network
(developed specifically for the Internet). TCP/IP defines a suite or group of
protocols and not only TCP and IP.
Throughput - The amount of data moved successfully from one place to another in a given time period.
Topology - A network's topology is a logical characterization of how the
devices on the network are connected and the distances between them. The
most common network devices include hubs, switches, routers, and gateways.
Most large networks contain several levels of interconnection, the most important of which include edge connections, backbone connections, and wide-area
connections.

UTP - Unshielded twisted pair is the most common kind of copper telephone
wiring. Twisted pair is the ordinary copper wire that connects home and many
business computers to the telephone company. To reduce crosstalk or electromagnetic induction between pairs of wires, two insulated copper wires are
twisted around each other. Each signal on twisted pair requires both wires.
Since some telephone sets or desktop locations require multiple connections,
twisted pair is sometimes installed in two or more pairs, all within a single
cable.
