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 oper-

ation 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. Refer to the

game’s user guide for more information.

What is ad-hoc mode?

When a wireless network is set to ad-hoc mode, the wireless-equipped com-

puters are configured to communicate directly with each other. The ad-hoc

wireless network will not communicate with any wired network.

Would the information be intercepted while transmitting on air?

Instant Wireless products feature two-fold protection in security. On the hard-

ware side, 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.

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.

Common Problems and Solutions

Protocol (IP) addresses in an organization's network. Using the Internet's set of

protocol, 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 espe-

cially useful in education and other environments where users change fre-

quently. Using very short leases, DHCP can dynamically reconfigure networks

in which there are more computers than there are available IP addresses.

DHCP supports static addresses for computers containing Web servers that

need a permanent IP address.

Download

- To receive a file transmitted over a network. In a communications

session, download means receive, upload means transmit.

Driver

- A software module that provides an interface between a network inter-

face card 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.

DSL

(

igital

ubscriber

ine) - A technology that dramatically increases the

digital capacity of ordinary telephone lines into the home or office and, by

employing unused bandwidth, still allows for normal phone usage. DSL pro-

vides "always-on" operation, eliminating the need to dial in to the service.

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.

Ethernet

- IEEE standard network protocol that specifies how data is placed

on and retrieved from a common transmission medium.

Appendix B: Glossary

802.11b

- One of the IEEE standards for wireless networking hardware.

Products that adhere to a specific IEEE standard will work with each other,

even if they are manufactured by different companies. The 802.11b standard

specifies a maximum data transfer rate of 11Mbps, an operating frequency of

2.4GHz, and WEP encryption for security. 802.11b networks are also referred

to as Wi-Fi networks.

802.11g

- A proposed, but as yet unratified extension of the IEEE 802.11 stan-

dard for wireless networking hardware. The draft 802.11g specifications used

by Linksys specify a maximum data transfer rate of 54Mbps using OFDM

modulation, an operating frequency of 2.4GHz, backward compatibility with

IEEE 802.11b devices, and WEP encryption for security.

Adapter

- This is a device that adds network functionality to your PC, game

console, etc.

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 or as peer-to-peer mode, and is

useful at a departmental scale.

Bit

- A binary digit. The value - 0 or 1-used in the binary numbering system.

Also, the smallest form of data.

Broadband

- A data-transmission scheme in which multiple signals share the

bandwidth of a medium. This allows the transmission of voice, data and video

signals over a single medium. Cable television uses broadband techniques to

deliver dozens of channels over one cable.

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.

DHCP

(

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.

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.

IEEE

(The

nstitute of

lectrical and

lectronics

ngineers) - 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.

(

nternet

rotocol) - The method or protocol by which data is sent from one

computer to another on the Internet. It is a standard set of rules, procedures, or

conventions relating to the format and timing of data transmission between two

computers that they must accept and use to be able to understand each other.

IP Address

- In the most widely installed level of the Internet Protocol (IP)

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.

LAN

(

ocal

rea

etwork) - 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

(

edia

ccess

ontrol)

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.

Network

- A system that transmits any combination of voice, video and/or data

between users.

OFDM

- Developed for wireless applications, Orthogonal Frequency Division

Multiplexing (OFDM) technology offers superior performance--increased data

rates and more reliable transmissions--than previous technologies, such as

DSSS. OFDM is a scheme in which numerous signals of different frequencies

are combined to form a single signal for transmission on the medium.

OFDM works by breaking one high-speed data stream into a number of lower-

speed data streams, which are then transmitted in parallel. Each lower speed

stream is used to modulate a subcarrier. Essentially, this creates a multi-carrier

transmission by dividing a wide frequency band or channel into a number of

narrower frequency bands or sub-channels. OFDM is also used for other appli-

cations, including powerline networking.

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. For exam-

ple, the serial and parallel ports on a personal computer are external sockets for

plugging in communications lines, modems and printers.

RJ-45

(

egistered

ack-

) - 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 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.

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
