Briefly pressing the Reset Button will refresh the Wireless AP +

Cable/DSL Router’s connections, potentially clearing any jammed links.

To Reset the Wireless AP + Cable/DSL Router’s factory default settings, power

off the Router and then press the Reset button. Then, power on the Router and

press the Reset button again. This should be done only if you are experiencing

heavy routing problems, and only after you have exhausted all of the other trou-

bleshooting options. By resetting the Wireless AP + Cable/DSL Router, you

run the risk of creating conflicts between your PCs’ actual IP Addresses and

what the Wireless AP + Cable/DSL Router thinks their IP Addresses should be.

You may be forced to reboot the entire system(s).

If the Wireless AP + Cable/DSL Router locks up, simply power it down for 3

to 5 seconds by removing the power cable from the Wireless AP + Cable/DSL

Router’s Power Port. Leaving the power off for too long could result in the

loss of network connections.

Planning Your Wireless Network

A wireless LAN is a group of computers, each equipped with one Instant

Wireless

Network PC Card. Computers in a wireless LAN must be config-

ured to share the same radio channel.

Wireless LAN configurations are appropriate for branch level departments or

SOHO operations.

The Instant Wireless

Network PC Card provides access to a wired LAN for

wireless workstations. An integrated wireless and wired LAN is called an

Infrastructure configuration. A group of Instant Wireless

Network PC Card

users and a Wireless AP + Cable/DSL Router compose a Basic Service Set

(BSS). Each PC utilizing an Instant Wireless

Network PC Card in a BSS can

talk to any computer in a wired LAN infrastructure via the Wireless AP +

Cable/DSL Router.

An infrastructure configuration extends the accessibility of an Instant

Wireless

Network PC Card PC to a wired LAN, and doubles the effective

wireless transmission range for two Instant Wireless

Network PC Card PCs.

Since the Wireless AP + Cable/DSL Router is able to forward data within its

BSS, the effective transmission range in an infrastructure LAN is doubled.

The use of a unique ID in a BSS is essential. All PCs using an Instant

Wireless

Network PC Card configured without roaming options in an inde-

pendent BSS must be configured with a BSS ID used in the BSS.

The Wireless LAN Infrastructure configuration is appropriate for enterprise-

scale wireless access to a central database, or as a wireless application for

mobile users.

to a wireless network is made.

Printer/Err Red. The Error LED illuminates when there is an error with

the PrintServer. To correct this, clear your print queue. If that

does not work, reset your printer. If that does not work, power

off the Wireless AP + Cable/DSL Router.

Printer/Act Green. The Act LED flickers when the PrintServer is sending

Infrastructure mode also supports roaming capabilities for mobile users. More

than one BSS can be configured as an Extended Service Set (ESS). This con-

tinuous network allows users to roam freely within an ESS. All PCs using an

Instant Wireless

Network PC Card within one ESS must be configured with

the same ESS ID and use the same radio channel.

Before enabling an ESS with roaming capability, choosing a feasible radio

channel and optimum position of the Wireless AP + Cable/DSL Routers is rec-

ommended. Proper Wireless AP + Cable/DSL Router positioning combined

with a clear radio signal will greatly enhance performance.

Connecting the EtherFast

Wireless AP + Cable/DSL Routerto

Your Network

Unlike a simple hub or switch, the setup of the Wireless AP + Cable/DSL

Router consists of more than simply plugging everything together. Because the

Router acts as a DHCP server for your Network, you will have to set some val-

ues within the Router, and also configure your networked PCs to accept the IP

Addresses the Router chooses to assign them.

You will need the following values from your ISP in order to install the

Wireless AP + Cable/DSL Router:

• Your broadband-configured

PC’s fixed Internet IP Address

(if applicable)

• Your broadband-configured

PC’s Computer Name and Workgroup Name

• Your Subnet Mask

• Your Default Gateway

• Your Primary DNS IP address

Whoever installed your broadband access should have left this information

with you. If not, call your ISP and they will be able to supply you with it.

Static IP Addresses A Static IP address is an IP address permanently assigned

to a computer in a TCP/IP network. Static IP addresses are usually assigned to

networked devices, which are consistently accessed by multiple users, such as

Server PCs, or printers. If you are using the Router to share your cable or DSL

Internet connection, contact your ISP to see if they have assigned your home or

business a Static IP address. You will need that address during the Router’s con-

figuration.

3. Connect an RJ-45 (network) cable to the Wireless AP + Cable/DSL

Router in either the PC or Uplink port. The PC port is used when con-

necting the Wireless AP + Cable/DSL Router to a single PC and the Uplink

port is used when connecting to a 10/100 Network. Then, connect the other

end of the Ethernet cable to either a PC or a network device. The Wireless

AP + Cable/DSL Router will then be connected to your 10/100 Network.

4. Connect another RJ-45 (network) cable to the Wireless AP + Cable/DSL

Router in the WAN port. The other end of the cable is used to connect the

Wireless AP + Cable/DSL Router to your Cable/DSL modem. Connect to

your Cable/DSL modem at this time.

5. Connect the AC Power Adapter to the Wireless AP + Cable/DSL

Router’s Power Socket. Only use the power adapter supplied with the

Wireless AP + Cable/DSL Router. Use of a different adapter may result in

product damage.

6. Verify that the LEDs are functioning. The Power LED should remain on,

while the Diag LED will flash and turn off right away. If the Diag LED

remains on, there is a hardware error. Refer to the Troubleshooting section

for resolution.

The Hardware Installation is complete.

Dynamic IP Addresses A dynamic IP address is an IP address that is automati-

cally assigned to a client station (computer, printer, etc.) in a TCP/IP network.

Dynamic IP addresses are typically assigned by a DHCP server on your

Network, which can be a computer on the network or another piece of hard-

ware, such as the Router. A dynamic IP address may change every time your

computer connects to the network.

DHCP (Dynamic Host Configuration Protocol) DHCP automatically assigns IP

addresses to client stations logging onto a TCP/IP network. DHCP eliminates

having to manually assign permanent IP addresses to every device on your net-

work. DHCP typically runs in servers and is also found in network devices such

as Routers.

1. Locate an optimum location for the Wireless AP + Cable/DSL Router.

The best place for your Wireless AP + Cable/DSL Router is usually at the

center of your wireless network, with line of sight to all of your mobile sta-

tions.

2. Insert the Instant Wireless

Network PC Card into the slot. With the

Network PC Card’s 68-pin connector facing the slot in the rear and the

“Network PC Card” label facing up, slide the Network PC Card completely

into the Wireless AP + Cable/DSL Router.

NNoottee::

Some ISPs—most notably some cable providers—

configure their networks so that you do not have to enter a

full Internet address into your web browser or e-mail appli-

cation to reach your home page or receive your e-mail. If

your Internet home page address is something very simple,

such as “www”, rather than “www.linksys.com”, or your e-mail server’s

address is something similar to “e-mail” or “pop3”, rather than

“pop.mail.linksys.com”, you

Troubleshooting

Common Problems and Solutions

This section provides possible solutions to problems regarding the installation and

operation of the Cable/DSL Router. Read the description below to solve your prob-

lems. If you can’t find an answer here, check the Frequently Asked Questions section

or the Linksys website at www.linksys.com.

1. I can’t connect to the Wireless AP + Cable/DSL Router.

• Verify that the Wireless AP + Cable/DSL Router is properly installed, LAN

connections are OK, and it is powered ON.

• Make sure that your PC and the Wireless AP + Cable/DSL Router are on the

same network segment. If you are not sure, initiate the DHCP function and let

the PC get the IP address automatically.

• Make sure that your PC is using an IP address within the default range of

192.168.1.2 to 192.168.1.254 and thus compatible with the Wireless AP +

Cable/DSL Router’s default IP Address of 192.168.1.1.

• The Network Mask should be set to 255.255.255.0 to match the Wireless AP

+ Cable/DSL Router. In the Wireless AP + Cable/DSL Router, you can check

these settings by going to the Basic Setup screen.

2. The Diag LED stays lit when it shouldn’t.

• The Diag LED lights up when the device is first powered up. Meantime, the

system will boot up itself and check for proper operation. After finishing the

checking procedure, the LED turns off to show the system is working fine. If

the LED remains lit after this time, the device is not working properly. First, try

restoring the Wireless AP + Cable/DSL Router’to it’s default settings by hold-

ing down the Reset button for more than five seconds. If the LED remains on

Does the Wireless AP + Cable/DSL Router support any operating system other than

Windows 95, 98, Millennium, NT, or 2000? The Wireless AP + Cable/DSL

Router’s Web Utility is configured via the Internet web browser on your

Linux system. The PrintServer, though, is configured through Windows and

will not function under Linux. Linksys does not, at this time, provide techni-

cal support for setup, configuration or troubleshooting of any non-Windows

operating systems.

Does the Wireless AP + Cable/DSL Router support ICQ send file? Yes, with the fol-

lowing fix: ICQ menu-> preference -> connections tab-> check "I am behind

a firewall or proxy", and set the firewall time-out to 80 seconds in firewall

setting. The Internet user can then send a file to a user behind the Wireless AP

+ Cable/DSL Router.

I setup an Unreal Tournament Server, but others on the LAN cannot join. What do I

need to do? If you have a dedicated Unreal Tournament server running, you

need to create a static IP for each of the LAN computers and forward ports

7777, 7778, 7779, 7780, 7781, and 27900 to the IP address of the server. If

you want to use the UT Server Admin, forward another port (8080 usually

works well), then in the [UWeb.WebServer] section of the server.ini file, set

the ListenPort to 8080 (to match the mapped port above) and ServerName to

the IP assigned to the Router from your ISP.

How do I get

Half-Life: Team Fortress

to Work with the Wireless AP + Cable/DSL

Router? The default client port for Half-Life is 27005. The computers on

your LAN need to have "+clientport 2700x" to the HL shortcut command

line; the x would be 6, 7, 8, and on up. This lets multiple computers connect

to the same server. One problem: version 1.0.1.6 won't let multiple comput-

ers with the same CD key connect at the same time, even if on the same LAN

(not a problem with 1.0.1.3). As far as hosting games, the HL server does not

need to be in the DMZ. Just forward port 27015 or 27016 to the local IP of

the server computer. There remains, however, a problem with people being

booted after a few minutes with an "illegible server message."

Can multiple gamers on the LAN get on one game server and play simultaneously

with just one public IP address? It depends on which network game or what

kind of game server you are using. For example, Unreal Tournament supports

multi-login with one public IP.

Can I use firmware for other routers with my Wireless AP + Cable/DSL Router? No.

If you attempt to use other router's firmware, you could damage your router.

Only use firmware specifically written for the Wireless AP + Cable/DSL

Router as posted on the Linksys web site: www.linksys.com.

What is the maximum number of IP addresses and users supported by the Wireless

AP + Cable/DSL Router? The Wireless AP + Cable/DSL Router supports up to

253 IP addresses and users.

Where is the Wireless AP + Cable/DSL Router installed on the network? In a typi-

cal environment, the Wireless AP + Cable/DSL Router is installed between

the Cable/DSL Modem and the LAN. Plug the Wireless AP + Cable/DSL

Router into the Cable/DSL Modem's Ethernet port.

Does the Wireless AP + Cable/DSL Router support IPX or AppleTalk? No. TCP/IP

is the only protocol standard for the Internet and has become the global stan-

dard for communications. IPX, a NetWare communications protocol used

only to route messages from one node to another, and AppleTalk, a commu-

nications protocol used on Apple and Macintosh networks, can be used from

LAN to LAN connections, but those protocols cannot connect from WAN to

LAN.

Does the WAN connection of the Wireless AP + Cable/DSL Router support 100Mb

Ethernet? Because of the speed limitations of broadband Internet connections,

the Wireless AP + Cable/DSL Router’s current hardware design supports

10Mb Ethernet on its WAN port. It does, of course, support 100Mbps over in

the auto-sensing Fast Ethernet 10/100 switch on the LAN side of the Wireless

AP + Cable/DSL Router.

What is Network Address Translation and what is it used for? Network Address

Translation (NAT) translates multiple IP addresses on the private LAN to one

public address that is sent out to the Internet. This adds a level of security

since the address of a PC connected to the private LAN is never transmitted

on the Internet. Furthermore, NAT allows the Wireless AP + Cable/DSL

Router to be used with low cost Internet accounts, such as cable or DSL

modems, where only one TCP/IP address is provided by the ISP. The user may

have many private addresses behind this single address provided by the ISP.

Frequently Asked Questions

To achieve true seamless connectivity, the wireless LAN must incorporate a

number of different functions. Each node and Wireless AP + Cable/DSL

Router, 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 dynam-

ic RF networking technology that links Wireless AP + Cable/DSL Routers 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 AP + Cable/DSL Router and the distance of each Wireless AP +

Cable/DSL Router to the wired backbone. Based on that information, the node

next selects the right Wireless AP + Cable/DSL Router 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 nodes RF transmitter regularly checks the sys-

tem to determine whether it is in touch with the original Wireless AP +

Cable/DSL Router or whether it should seek a new one. When a node no longer

receives acknowledgment from its original Wireless AP + Cable/DSL Router,

it undertakes a new search. Upon finding a new Wireless AP + Cable/DSL

Router, it then re-registers, and the communication process continues.

What is BSS ID? 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 ESS ID? 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 served as a continuous connection to the network wireless stations

and Wireless AP + Cable/DSL Routers within an ESS must be configured with

the same ESS ID and the same radio channel.

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.

What is Spread Spectrum? Spread Spectrum technology is a wideband radio

frequency technique developed by the military for use in reliable, secure, mis-

sion-critical communications systems. It is designed to trade off bandwidth

How do I get mIRC to work with the Wireless AP + Cable/DSL Router? Set port for-

warding to 113 for the computer on which you are using mIRC.

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 net-

work. Consult the application's user guide to determine if it supports operation

over a network.

Can I play computer games with other members of the cordless 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? The IEEE 802.11b Wireless LAN standards

subcommittee, which is formulating a standard for the industry. The objective

is to enable wireless LAN hardware from different manufacturers to communi-

cate.

What IEEE 802.11 features are supported? The Wireless AP + Cable/DSL Router

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? An Ad-hoc wireless LAN is a group of computers, each with

a WLAN adapter, connected as an independent wireless LAN. Ad-hoc wireless

LAN is applicable at a departmental scale for a branch or SOHO operation.

What is Infrastructure? An integrated wireless and wired LAN is called an

Infrastructure configuration. Infrastructure is applicable to enterprise scale for

wireless access to central database, or wireless application for mobile workers.

What is Roaming? Roaming is the ability of a portable computer user to com-

municate continuously while moving freely throughout an area greater than that

covered by a single Wireless Network Access Point. Before using the roaming

function, the PC must make sure that it is the same channel number with the

Wireless AP + Cable/DSL Router of dedicated coverage area.

Appendix

Virtually all Internet addresses are configured with words or characters (i.e.,

www.linksys.com, www.yahoo.com, etc.) In actuality, however, these Internet

addresses are assigned to IP addresses, which are the true addresses on the

Internet.

IP and web addresses, however, can sometimes be long and hard to remember.

Because of this, certain ISPs will shorten their server addresses to single words

or codes on their users’ web browser or e-mail configurations. If your ISP’s E-

mail and Web server addresses are configured with single words (“www”, “e-

mail”, “home”, “pop3”, etc.) rather than whole Internet Addresses or IP

Addresses, the Router may have problems sending or receiving mail and

accessing the Internet. This happens because the Router has not been config-

ured by your ISP to accept their abbreviated server addresses.

The solution is to determine the true web addresses behind your ISPs code

words. You can determine the IP and web addresses of your ISP’s servers by

“pinging” them.

Step One: Pinging for an IP Address

The first step to determining your ISP’s web and e-mail server address is to

ping its IP Address.

1. Power on the computer and the cable or DSL modem, and restore the

network configuration set by your ISP if you have since changed it.

2. Click Start, then Run, and type "command". This will bring up the DOS

Window.

efficiency for reliability, integrity, and security. In other words, more band-

width 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, provid-

ed 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-hop-

ping spread-spectrum (FHSS) uses a narrowband carrier that changes frequen-

cy in a pattern that is known to both transmitter and receiver. Properly syn-

chronized, the net effect is to maintain a single logical channel. To an unin-

tended 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 recov-

ered. Even if one or more bits in the chip are damaged during transmission, sta-

tistical 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? 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 series 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 bit shared key algorithm, as described in the IEEE 802.11 stan-

dard.

“mail” could conceivably change, it is likely that this web address will not.

3. Replace your ISP’s abbreviated server address with this extended web

address in the corresponding Internet application (web browser, e-mail

Once you have replaced the brief server address with the true server address,

the Router should have no problem accessing the Internet through that Internet

application.

Instant Broadband

Series

Twisted-Pair Cabling

There are different grades, or categories, of twisted-pair cabling. Category 5 is

the most reliable and is highly recommended. Category 3 is a good second

choice. Straight-through cables are used for connecting computers to a hub.

Crossover cables are used for connecting a hub to another hub (there is an

exception: some hubs have a built-in uplink port that is crossed internally,

which allows you to link or connect hubs together with a straight-through cable

instead).

You can buy pre-made Category 5

cabling, or cut and crimp your own.

Category 5 cables can be purchased or

crimped as either straight-through or

crossover. Inside a Category 5 cable are

8 thin, color-coded wires inside that run

from one end of the cable to the other.

All 8 wires are used. In a straight-

through cable, wires 1, 2, 3, and 6 at one

end of the cable are also wires 1, 2, 3,

and 6 at the other end. In a crossover

cable, the order of the wires change from

one end to the other: wire 1 becomes 3,

and 2 becomes 6. See the diagrams on

the next page for more detailed informa-

tion on straight-through

and crossover cabling.

To determine which wire is wire number 1, hold the cable so that the end of the

plastic RJ-45 tip (the part that goes into a wall jack first) is facing away from

you. Face the clip down so that the copper side faces up (the springy clip will

now be parallel to the floor).When looking down on the copper side, wire 1 will

be on the far left.

DNS - The domain name system (DNS) is the way that Internet domain name

are located and translated into Internet Protocol (IP) addresses. A domain name

is a meaningful and easy-to-remember "handle" for an Internet address.

DSSS - Also known as “Direct Sequence Spred Spectrum”, this is a variety of

radio transmission methods that continuously change frequencies or signal pat-

terns. Direct sequence spread spectrum (DSSS), which is used in CDMA, mul-

tiplies the data bits by a very fast pseudo-random bit pattern (PN sequence) that

"spreads" the data into a large coded stream that takes the full bandwidth of the

channel

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.

ESS - More than one BSS in a network.

FHSS - Also known as “Frequency Hopping Spread Spectrum”. 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.

Firewall - A firewall is a set of related programs, located at a network gateway

server, that protects the resources of a network from users from other networks.

(The term also implies the security policy that is used with the programs.) An

enterprise with an intranet that allows its workers access to the wider Internet

installs a firewall to prevent outsiders from accessing its own private data

resources and for controlling what outside resources to which its own users

have access.

Basically, a firewall, working closely with a router program, examines each

network packet to determine whether to forward it toward its destination.

Firmware - Programming that is inserted into programmable read-only mem-

ory (programmable read-only memory), thus becoming a permanent part of a

computing device.

Glossary

Ad-hoc Network - An ad-hoc network is a wireless network or other small net-

work in which some of the network devices are part of the network only for the

duration of a communications session while in some close proximity to the rest

of the network.

BSS (Basic Service Set) - A group of Instant Wireless

Network PC Card

users and a Wireless AP + Cable/DSL Router.

Default Gateway - The router used to forward all traffic that is not addressed

to a station within the local subnet.

DHCP (Dynamic Host Configuration Protocol) - Aprotocol 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 con-

nection 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 dis-

tribute 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.

DMZ - A DMZ (demilitarized zone) is a computer host or small network

inserted as a "neutral zone" between a company's private network and the out-

side public network. It prevents outside users from getting direct access to a

server that has company data.

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 Address - The MAC (Media Access Control) address is your computer's

unique hardware number.

mIRC - mIRC runs under Windows and provides a graphical interface for log-

ging onto IRC servers and listing, joining and leaving channels.

NAT - NAT (Network Address Translation) is the translation of an Internet

Protocol address (IP address) used within one network to a different IP address

known within another network. One network is designated the inside network

and the other is the outside.

Network Mask - also known as the “Subnet Mask”.

Packet Filtering - Discarding unwanted network traffic based on its originat-

ing address or range of addresses or its type (e-mail, file transfer, etc.).

PCMCIA - The PCMCIA (Personal Computer Memory Card International

Association) is an industry group organized in 1989 to promote standards for a

credit card-size memory or I/O device that would fit into a personal computer,

usually a notebook or laptop computer.

Ping - (Packet INternet Groper) An Internet utility used to determine whether

a particular IP address is online. It is used to test and debug a network by send-

ing out a packet and waiting for a response.

PPPoE (Point to Point Protocol over Ethernet) - A method used mostly by DSL

providers for connecting personal computers to a broadband modem for

Internet access. It is similar to how a dial-up connection works but at higher

speeds and quicker access.

PPTP (Point-to-Point Tunneling Protocol) - A protocol (set of communication

rules) that allows corporations to extend their own corporate network through

private "tunnels" over the public Internet. Effectively, a corporation uses a

wide-area network as a single large local area network. A company no longer

needs to lease its own lines for wide-area communication but can securely use

the public networks. This kind of interconnection is known as a virtual private

network.

IEEE - The Institute of Electrical and Electronics Engineers. The IEEE

describes itself as "the world's largest technical professional society -- promot-

ing 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.

Infrastructure - An infrastructure network is a wireless network or other small

network in which the wireless network devices are made a part of the network

through the Access Point which connects them to the rest of the network.

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 identi-

fies 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

IPCONIFG - A utility that provides for querying, defining and managing IP

addresses within a network. A commonly used utility, under Windows NT and

2000, for configuring networks with static IP addresses.

IPSec - IPSec (Internet Protocol Security) is a developing standard for securi-

ty at the network or packet processing layer of network communication. A big

advantage of IPSec is that security arrangements can be handled without

requiring changes to individual user computers.

ISP - An ISP (Internet service provider) is a company that provides individuals

and companies access to the Internet and other related services such as Web site

building and virtual hosting.

Network applications that want to save processing time because they have very

small data units to exchange (and therefore very little message reassembling to

do) may prefer UDP to TCP.

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 electro-

magnetic 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.

Virtual Server - Multiple servers that appear as one server, or one system

image, to the operating system or for network administration

WA N - A communications network that covers a wide geographic area, such as

state or country.

WEP (Wired Equivalent Privacy) - A data privacy mechanism based on a 64-

bit shared key algorithm, as described in the IEEE 802.11 standard.

WINIPCFG - Configuration utility based on the Win32 API for querying,

defining and managing IP addresses within a network. A commonly used util-

ity, under Windows 95, 98, and Millennium, for configuring networks with

static IP addresses.

PrintServer - A hardware device that enables a printer to be located anywhere

in the network.

RJ-45 - A connector similar to a telephone connector that holds up to eight

wires, used for connecting Ethernet devices.

Roaming - The ability to use a wireless device and be able to move from one

access point’s range to another without losing the connection.

Static IP Address - A permanent IP address that is assigned to a node in a

TCP/IP network.

Subnet Mask - The method used for splitting IP networks into a series of sub-

groups, 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.

TCP (Transmission Control Protocol) - A method (protocol) used along with

the Internet Protocol (Internet Protocol) to send data in the form of message

units between computers over the Internet. While IP takes care of handling the

actual delivery of the data, TCP takes care of keeping track of the individual

units of data (called packet) that a message is divided into for efficient routing

through the Internet.

TCP/IP - Transmission Control Protocol/Internet Protocol (TCP/IP) is the

basic communication language or protocol of the Internet. It can also be used

as a communications protocol in a private network (either an intranet or an

extranet). When you are set up with direct access to the Internet, your comput-

er is provided with a copy of the TCP/IP program just as every other computer

that you may send messages to or get information from also has a copy of

TCP/IP.

UDP (User Datagram Protocol) - A communications method (protocol) that

offers a limited amount of service when messages are exchanged between com-

puters in a network that uses the Internet Protocol (IP). UDP is an alternative

to the Transmission Control Protocol (TCP) and, together with IP, is sometimes

referred to as UDP/IP. Like the Transmission Control Protocol, UDP uses the

Internet Protocol to actually get a data unit (called a datagram) from one com-

puter to another. Unlike TCP, however, UDP does not provide the service of

dividing a message into packets (datagrams) and reassembling it at the other

end. Specifically, UDP doesn't provide sequencing of the packets that the data

arrives in. This means that the application program that uses UDP must be able

to make sure that the entire message has arrived and is in the right order.
