WU830G PRELIMINARY 1-3

Simple Home Network Diagram

Your wireless USB adapter enables you to access files, printers, and

an Internet connection on your network. A sample Local Area

Network (LAN) is shown below:

Graphic of a LAN with the WU830G

connected to a laptop computer

In the example above, the Internet communicates with the modem,

which in turn communicates with the router. The router acts as the

gateway to your network, sending information to whichever device

asks for information. In this example, the USB adapter enables your

notebook computer to be part of the wireless network.

Wireless Connections

Your wireless USB adapter uses a radio transmission technology

defined by the Institute of Electrical and Electronics Engineers (IEEE)

called 802.11 Wireless Fidelity (Wi-Fi). This standard is subdivided

into distinct categories of speed and the frequency spectrum used,

designated by the lower case letter after the standard.

For example, your USB adapter can work with both the ‘b’ and ‘g’

specifications. The 802.11b specification transmits data rates up to

11 Mbps while the 802.11g specification transmits data rates up to

54 Mbps. Both standards operate in the 2.4 GHz range. These are

theoretical speeds so your performance may vary.

A Word About Data Rates: Data rate is the speed at which individual bits of data flow through

a channel. It is not the same speed at which entire files are uploaded or downloaded. These

speeds will vary, and are often less than the maximum data rate. Upload and download

speeds are affected by several factors including, but not limited to: the capacity of and the

services offered by your cable operator or broadband service provider, channel capacity,

network traffic, computer equipment, type of server, number of connections to server, and

availability of Internet router(s).

Section 2:Installation

Before You Begin

You need to collect information so that you can setup your WU830G

correctly. Depending upon where you are connecting, the type of

information required is divided between business (enterprise users)

and home settings (small office/home office).

Also, you need to consider the type of security to enable for your

wireless connection. A discussion of the types of security available

follows this section.

Enterprise Users

Obtain the following information from your network administrator:

Network names (SSID) of the specific wireless networks to which

you are going to connect.

WPA (Wi-Fi Protected Access) wireless network key information

(may include network authentication type, encryption type,

network key) for any WPA enabled networks to which you want to

connect.

WEP (Wired Equivalent Privacy) wireless network key information

(network key) for any WEP enabled networks to which you want

to connect.

For Microsoft Windows® networking, the customer name and

workgroup name.

For a network account, the domain name, a user name, and a

password.

An IP address (if not using a DHCP server).

Networks connected to an authentication server, if any.

Section 2 Installation

2-2 PRELIMINARY WU830G

Small Office/Home Office Users

The access point that communicates with the WU830G has a

pre-assigned network name (SSID) that the WU830G recognizes

upon startup.

If you are setting up a new wireless network and want to use

WEP security, use any string of characters for the network key. If

this feature is enabled on the wireless network, you’ll use the

same network key for your WU830G.

If you are connecting to an existing WEP enabled network, obtain

the network key from the access point.

If you are connecting to a WPA-enabled access point, obtain the

WPA (Wi-Fi Protected Access) wireless network key information

(network authentication type, encryption type, network key) from

the access point.

Security Options

The WU830G is designed for both the home user and business.

WPA (Wi-Fi Protected Access) protocol is designed into the chipset.

WPA is a powerful, standards-based, interoperable security

technology for wireless local area networks (the subset of the future

IEEE Std 802.11i standard) that encrypts data sent over radio waves.

The WPA protocol was developed to overcome the weaknesses of

the WEP (Wired Equivalent Privacy) protocol. Both protocols require

the use of network key information, and either protocol can be

enabled or disabled, depending on the type of network connection

being made.

Various options are available for selecting network authentication and

data encryption. It is important for you to understand these options

when deciding which (if any) security protocol to use.

Security Example

If you want to use a more secure protocol, the wireless network to

which you are connecting must also support that protocol. For

example, you decide to enable WPA-PSK on your WU830G, a good

choice because of the robust security WPA-PSK offers. However, the

slightly older wireless network you want to connect to only supports

WEP, which means that you cannot use WPA (and should use WEP)

because the security protocols must match between the network

adapter and the access point.

determine the IP Address of your USB adapter.

1 Open a command prompt by clicking Start and Run.

2 For Windows 98 and ME, in the Open field, type command and

press Enter or OK.

For Windows 2000 and XP, type cmd. Or, navigate using your

Start button to Programs>Accessories>Command Prompt.

3 In the Command window, type ipconfig.

You should see an IP address for your adapter, for example:

Ethernet Adapter Local Area Connection:

Connection-specific DNS Suffix. . : Example.example.example.com.

IP Address. . . . . . . . . . . . : 192.168.10.10

Subnet Mask . . . . . . . . . . . : 255.255.255.0

Default Gateway . . . . . . . . . : 192.168.10.1

4 If using a router at home, in the Command window, type ping

followed by the Router’s IP address and press Enter. For

example, type ping 192.168.10.1

The router’s IP address is most likely the default gateway.

If you receive a reply (the first word will be Reply…), then

your computer is connected to the router. Proceed to Step 4.

If you do NOT receive a reply, repeat steps 1 – 4 on a

different computer to verify that the first computer is not the

cause of the problem.

5 In the Command window, type ping and your ISP’s default

gateway IP Address and press Enter. You can determine your

ISP’s default gateway by examining your modem and or router.

Refer to the instructions provided with your modem/router.

If you receive a reply (For example, Reply from

216.109.125.72…), then your connection to the Internet is

live.

If you do NOT receive a reply, repeat steps 1 – 5 on a

different computer to verify that the first computer is not the

cause of the problem.

6 If you cannot determine your ISP’s default gateway, ping

www.yahoo.com or another known web location.

peripheral device to the network or to some other device. A

wireless adapter connects a computer to the wireless LAN.

Address translation

See NAT.

Ad-Hoc Network

A temporary local area network connecting access clients

together, usually just for the duration of the communication

session. The clients communicate directly to each other and not

through an established, such as through a router. Also known as:

IBSS (Independent Basic Service Set).

ASCII

The American Standard Code for Information Interchange refers

to alphanumeric data for processing and communication

compatibility among various devices; normally used for

asynchronous transmission.

Bandwidth

The transmission capacity of a medium in terms of a range of

frequencies. Greater bandwidth indicates the ability to transmit

more data over a given period of time.

bps

Bits Per Second

Broadband

A communications medium that can transmit a relatively large

amount of data in a given time period.

Section 5 Glossary

5-2 PRELIMINARY WU830G

BSS

Basic Service Set. A configuration of Access Points that

communicate with each other without resorting any infrastructure.

Also known as Ad-Hoc networks. Also see ESS.

Client

In a client/server architecture, a client is a computer that requests

files or services such as file transfer, remote login, or printing

from the server. On an IEEE 802.11b/g wireless LAN, a client is

any host that can communicate with the access point. Also called

a CPE. A wireless client is also called a “station.” Also see server.

Coaxial Cable

A type of cable consisting of a center wire surrounded by

insulation and a grounded shield of braided wire. The shield

minimizes electrical and radio frequency interference. Coaxial

cable has high bandwidth and can support transmission over long

distances.

CPE

Customer Premise Equipment: typically computers, printers, etc,

that are connected to the gateway at the subscriber location. CPE

can be provided by the subscriber or the cable service provider.

Also called a client.

Crossover Cable

A crossover cable is a cable that is used to interconnect two

computers by "crossing over" (reversing) their respective pin

contacts. A crossover cable is sometimes known as a null

modem.

Default Gateway

A routing device that forwards traffic not destined to a station

within the local subnet.

DHCP

A Dynamic Host Configuration Protocol server dynamically

assigns IP addresses to client hosts on an IP network. DHCP

eliminates the need to manually assign static IP addresses by

“leasing” an IP address and subnet mask to each client. It

enables the automatic reuse of unused IP addresses.

DMZ

DeMilitarized Zone. This service opens one IP address to the

Internet, usually for online gaming, and acts as a buffer between

the Internet and your network.

Glossary Section 5

WU830G PRELIMINARY 5-3

DNS

The Domain Name System is the Internet system for converting

domain names (like www.motorola.com) to IP addresses. A DNS

server contains a table matching domain names such as

Internetname.com to IP addresses such as 192.169.9.1. When

you access the world-wide web, a DNS server translates the URL

displayed on the browser to the destination website IP address.

The DNS lookup table is a distributed Internet database; no one

DNS server lists all domain name to IP address matches.

Domain Name

A unique name, such as motorola.com, that maps to an IP

address. Domain names are typically much easier to remember

than are IP addresses. See DNS.

Download

To copy a file from one computer to another. You can use the

Internet to download files from a server to a computer.

Driver

Software that enables a computer to interact with a network or

other device. For example, there are drivers for printers, monitors,

graphics adapters, modems, Ethernet, USB, HPNA, and many

others.

DSL

Digital Subscriber Line

DSSS

Direct-Sequence Spread Spectrum. DSSS is a transmission

technology used in WLAN transmissions where a data signal at

the sending station is combined with a higher data rate bit

sequence, or chipping code, that divides the user data according

to a spreading ratio. The chipping code is a redundant bit pattern

for each bit that is transmitted, which increases the signal's

resistance to interference. If one or more bits in the pattern are

damaged during transmission, the original data can be recovered

due to the redundancy of the transmission.

Dynamic IP Address

An IP address that is temporarily leased to a host by a DHCP

server. The opposite of Static IP Address.

transmission speeds up to 10 Mbps, usually over unshielded,

twisted-pair wire terminated with RJ-45 connectors. Fast Ethernet

(100Base-T) provides speeds up to 100 Mbps. “Base” means

“baseband technology” and “T” means “twisted pair cable.”’

Each Ethernet port has a physical address called the MAC

address. Also see MAC address.
