Association Tab

Association refers to the ability to join a network, either infrastructure or adhoc. The most basic

requirement for associating with a network is specifying the correct name, or Service Set

Identifier (SSID), for the network.

Networks may also require a key for association. If this is the case for the network you are

configuring, you must enter the authentication and encryption types for your keys in the

Wireless Network Key section of this menu. To choose a value for these fields, click the down

arrow to the right of the appropriate file and highlight one of the values that appear in the drop-

down list.

Open and Shared authentication require no further configuration. To use WPA-PSK

authentication, you must click the Properties button next to this field and enter a shared secret

key.

For key encryption, you can choose either disabled or WEP. To configure WEP encryption,

click the Properties button next to this field. When you click this button, a menu similar to the

following appears.

Creating Encryption Keys Manually

When you specify that WEP is enabled for the network, the Configuration Utility selects Create

WEP Keys Manually, and allows you to enter keys as either alphanumeric or hexadecimal

characters. To enter a key, click in the field for any of the four WEP keys and begin typing. For

64-bit encryption, you must type exactly 5 alphanumeric or 10 hexadecimal characters in each

of the four key fields; for 128-bit encryption, you must type exactly 13 alphanumeric or 26

hexadecimal characters. You then click the OK button to create your encryption keys. After you

click the OK button, the Configuration Utility uses asterisks to mask your keys.

The Key index (advanced) field lets you specify which of the four encryption keys you use to

transmit data on your wireless LAN. You can change the default key by clicking on the up or

down arrow at the right of this field until the number of the key you want to use appears. As long

as the Access Point or computer with which you are communicating has the same key in the

same position, you can use any of the keys as the default.

Creating Encryption Keys Using a Passphrase

To create encryption keys using a passphrase, click the radio button next to Create WEP Keys

with Pass Phrase and type a character string in the Pass Phrase field. As with creating keys

manually, you must type exactly 5 alphanumeric or 10 hexadecimal characters for 64-bit

encryption, or exactly 13 alphanumeric or 26 hexadecimal characters for 128-bit encryption.

After you click the OK button, the Configuration Utility generates 4 WEP keys and uses asterisks

to mask your keys.

Appendix: Dell™ TrueMobile™ 1300 Wireless USB2.0

Adapter User's Guide

Wireless Local Area Network (WLAN)

Local Area Network (LAN) is a network in one location. Users at that location can share files, printers, and

other services. In a LAN, a networked computer that requests services is called a client. A Wireless Local

rea Network (WLAN) is a type of LAN that uses high frequency radio waves rather than wires to

communicate and transmit data among the network clients and devices. It is a flexible data communication

system implemented as an extension to, or as an alternative for, a wired LAN.

In a WLAN, wireless adapters are installed in clients, also called wireless clients. The adapter allows the

wireless client to communicate with the WLAN without cables. Instead, wireless clients send and receive

information through a path in the air called a channel.

The standards for a WLAN are based on the IEEE 802.11b/g standard. All Dell TrueMobile 802.11b/g-

compliant devices interoperate with other 802.11b/g-compliant wireless devices from other vendors. The WiFi

certification logo indicates that the wireless device has been tested by an independent organization and is

802.11b/g-compliant.

wireless client operates in either infrastructure mode or pee

-to-peer mode.

Infrastructure Mode: A WLAN with Wireless Broadband Routers

In infrastructure mode, wireless clients send and receive information through one or more Wireless

Broadband Routers. Wireless Broadband Routers are strategically located within an area to provide optimal

coverage for wireless clients. Wireless Broadband Routers and wireless clients constitute a WLAN.

Wireless Broadband Routers can be connected to a LAN of wired or wireless clients. The Wireless Broadband

Routers send and receive information from the LAN through this connection.

n Extended Service Set Identifier (ESSID) is used to identify the wireless clients and Wireless Broadband

Routers in a WLAN. All wireless clients and Wireless Broadband Routers in the WLAN must use the same

ESSID. A Basic Service Set Identifier (BSSID) uniquely defines each wireless client and Wireless Broadband

Router.

Peer-to-Peer Mode (Ad Hoc): A WLAN without Wireless Broadband Routers

In peer-to-peer mode, wireless clients directly send and receive information to other wireless clients without

using a Wireless Broadband Router.

Identifying a WLAN

n ESSID and BSSID are both Service Set Identifiers (SSID) that identify and control the wireless client’s

access to a given WLAN. The SSID is sometimes referred to as the network name. The SSID indicates what

WLAN you are referring to. In most cases, the user interface displays the SSID.

When installing a Wireless Broadband Router or wireless adapter in a wireless client, the installation program

asks you to enter the SSID.

ll wireless clients and Wireless Broadband Routers in a WLAN must use the same network name.

Encryption

In a WLAN, wireless clients and Wireless Broadband Routers send and receive information through the air.

Without implementing security, it is possible for an unauthorized person to intercept the information.

common way of implementing security and protecting information is encryption. Encryption applies a set of

instructions, called an algorithm, to information. The instructions combine the plain or clear text of information

with a sequence of hexadecimal numbers, called an encryption key.

Before transmitting information over the airwaves, the wireless client or Wireless Broadband Router encrypts

or scrambles the information. The Wireless Broadband Router or wireless client receiving the information

uses the same key to decrypt or unscramble the information. The information is only readable to WLAN

devices that have the correct encryption key. The longer the key is, the stronger the encryption.

The form of data encryption used by the Wireless Broadband Router is called Wired Equivalent Privacy

(WEP). When encryption is enabled, you must set the WEP key in the client to match the WEP key used by

the Wireless Broadband Router because you will ONLY associate to Wireless Broadband Routers that have a

matching WEP Key. For added security, change the encryption key often. WEP, or encryption, is an optional

feature that can be enabled or disabled.

There are two WEP encryption methods: 40(64)-bit and 104(128)-bit. 40-bit and 64-bit encryption is identical

similarly 104-bit and 128-bit encryption is identical. Some vendors use the term 40-bit; others use 64-bit. A

wireless device that claims to have 40-bit encryption interoperates with a device that claims to have 64-bit

encryption, and vice versa. A 40(64)-bit key consists of 10 hexadecimal numbers in five two-digit groups,

arrayed as follows:

Example Key #1: 1A:2E:3F:11:18

128-bit hexadecimal key has several trillion times as many possible combinations than a 40(64)-bit key. It

consists of 26 hexadecimal numbers arranged in thirteen two-digit groups, arrayed as follows:

Example Key #1: 1A:2D:3E:5F:4A:22:19:77:91:A1:B2:C3:D8

The examples above are for hexadecimal key format. Keys may also be in ASCII format. ASCII characters

consist of any numbers or letters in upper or lower case. The key may be 40(64)-bit ASCII, which consists of

five characters (for example: 12Abc). The key may also be 104(128)-bit ASCII, which consists of thirteen

characters (for example: AbCdEf1234567). Note the case of the letters is important and “abcde” is not the

same as “ABCDE”.

ll wireless clients and Wireless Broadband Routers in a WLAN must use the same encryption method and

key. The following two examples stress how important this point is.

Example 1

The encryption method for a Wireless Broadband Router is 40(64)-bit. The method for a wireless client is 128-

bit encryption. The client and Wireless Broadband Router cannot communicate with each other, even though

the selected key is the same. To resolve this problem, set the Wireless Broadband Router to use 128-bit

encryption.

Example 2

The encryption method is the same for the Wireless Broadband Router and wireless client. You select key 1

for the Wireless Broadband Router and key 2 for the wireless client. The wireless client cannot communicate

with the WLAN. To resolve this problem, select key 1 for the wireless client.

Glossary: Dell™ TrueMobile™ 1300 Wireless USB2.0

Adapter User's Guide

Access Point:

Sometimes referred to as a Wireless Broadband Router or Residential Gateway. An access point is a device

on an 802.11b/g wireless network that receives and retransmits data. It allows computers with wireless

network adapters to be connected, typically, to an Ethernet network.

Client:

client is a computer on a network.

Domain Name System (or Service) (DNS):

DNS is an Internet service that translates domain names into IP addresses. A DNS server keeps a database

of host computers, their respective domain names and IP addresses. When a domain name is requested, the

DNS server uses this database to send the user to the correct IP address.

The DNS system is really its own network. If one DNS server doesn't know how to translate a particular

domain name, it asks another one, and so on, until the correct IP address is returned.

Dynamic Host Configuration Protocol (DHCP):

DHCP is the process of automatically configuring TCP/IP settings for every computer on a network.

Encryption:

Encryption is a common way of implementing security and protecting information. Encryption applies a set of

instructions, called an algorithm, to information. The instructions combine the plain or clear text of information

with a sequence of hexadecimal numbers, called an encryption key.

Before transmitting information over the airwaves, the wireless client or access point encrypts or scrambles

the information. The access point or wireless client receiving the information uses the same key to decrypt or

unscramble the information. The information is only readable to WLAN devices that have the correct

encryption key. The longer the key is, the stronger the encryption.

802.11b-compliant wireless networks incorporate Wired Equivalent Privacy (WEP) technologies. There are

two WEP encryption methods: 64(40)-bit and 128-bit. 40-bit and 64-bit identical. Some vendors use the term

40-bit; others use 64-bit. A wireless device that claims to have 40-bit encryption interoperates with a device

that claims to have 64-bit encryption, and vice versa. A 64(40)-bit key consists of 10 hexadecimal numbers in

five two-digit groups, arrayed as follows:

Key #1: 1A:2F:3A:44:23

Key #2: 23:44:56:65:78

Key #4: 00:11:22:33:44:AA23:3F:FF:DE:23:44:56

ll wireless clients and access points in a WLAN must use the same encryption method and key.

Ethernet:

Ethernet is the most widely used local area networking technology. It is an industry-wide standard originally

developed by Xerox and formalized in 1980 by DEC, Intel, and Xerox. Ethernet networks transmit data at

10/100 Mbps using a specified protocol.

Ethernet Address (MAC Address):

n Ethernet address is a unique, pre-programmed address, sometimes referred to as a media access control

(MAC) address. Each computer on an Ethernet network has its own Ethernet address. This 12-digit

hexadecimal address is encoded into the circuitry of the computer’s network adapter when it is manufactured.

Other devices on the network use this address to identify the computer. This address is not the same as the

IP address that is assigned to computers on TCP/IP networks. On these networks, the IP address is

associated with the MAC address to enable network communication.

Internet Protocol (IP):

IP is the protocol used to send data from one computer to another over the Internet. The IP protocol describes

how Internet computers keep track of the IP address of each computer on the network and route packets of

data from one IP address to another.

IP Address:

n IP address provides unique identification for each computer on the Internet or on a local network. IP

addresses are usually expressed as a group of four numbers separated by periods, for example,

169.254.10.2. None of the numbers can be greater than 255. Each Ethernet interface has an IP address. For

the Dell™ TrueMobile™ 1300 Wireless USB Adapter, there is a LAN Ethernet interface; hence, there is a LAN

IP address.

Link Light:

link light is a light on a network device that indicates a good network connection. Hubs typically have a link

light for each port; although, they may not be labeled as such, and the lights may show other information.

These lights often blink for network activity. Some hubs display different colored lights for 10 Mbps and 100

Mbps. For more information, see the documentation accompanying your product.

Local Area Network (LAN):

LAN is a network in one location. The network lets users at that location share files, printers and other

services.

Network Adapter:

network adapter is a device expansion card that provides the physical connection between a computer and

the network. There are many types of adapters. They include PC cards for laptops, a card that fits into a slot

on your computer, just like you install a sound card or modem card, and embedded cards, embedded USB

adapters, USB adapters, and USB desktop adapters. Some newer computers have a network adapter already

built into the system. PC cards or cards that fit into a slot in the desktop are sometimes referred to as network

interface cards, or NICs.

Network Name (SSID):

ccess points are grouped together by an identifier called an ESSID. The ESSID is also referred to as a Net

ID. This identifier is a combination of any letters or numbers that are appropriate for the network environment.

ESSID is specifically for access points. When you talk about peer-to-peer networks, you cannot use the term

ESSID.

Service Set Identifier (SSID) is more generic and is a 32-character name that uniquely identifies all the

computers and equipments that make up a wireless network. A type of SSID is ESSID. Another type of SSID

is Basic Service Set Identifier (BSSID). The BSSID is the MAC address of a wireless adapter or access point.

Port:

port is a connector on a networking device, used to attach the network cable. Hubs and switches have

numerous ports that connect to computers on the network.

Protocol:

Protocol refers to a set of rules for sending and receiving information on a network. The rules determine the

format of the data that is transmitted and other aspects of networking, such as how errors are detected and

corrected. The protocol driver in each computer is software that adheres to these rules when sending and

receiving information. These drivers are also often called protocols.

Transmission Control Protocol/Internet Protocol (TCP/IP):

TCP/IP refers to the protocol that computers use to communicate over the Internet. TCP determines how a

computer breaks up data into small units, called "packets," to be sent to another computer and how the

receiving computer reassembles the packets into a single file. IP determines how the packets are routed

across the Internet. See Internet Protocol.

VLAN is a network of computers that behave as if they are connected to the same wire, even though they

may be physically located on different segments of a LAN. VLANs are configured through software rather than

hardware, which makes them extremely flexible. When a computer on a VLAN is physically moved to another

location, it can stay on the same VLAN without any hardware reconfigurations.

WEP (Wired Equivalent Privacy):

WEP data encryption is defined by the 802.11 standard to prevent (i) access to the network by "intruders"

using similar wireless LAN equipment and (ii) capture of wireless LAN traffic through eavesdropping. WEP

allows the administrator to define a set of respective "Keys" for each wireless network user based on a "Key

String" passed through the WEP encryption algorithm. Access is denied by anyone who does not have an

assigned key.

Wireless broadband router:

lso known as a "wireless residential gateway" or "SOHO router and access point," a wireless broadband

router is a device which connects to multiple PCs to a single broadband (cable or DSL) modem, allowing the

PCs to share internet access, exchange files between PCs, and share access to network devices such as

printers.

Wireless Local Area Network (WLAN):

WLAN is a type of Local Area Network (LAN) that uses high frequency radio waves rather than wires to

communicate and transmit data among the network clients and devices. It is a flexible data communication

system implemented as an extension to, or as an alternative for, a wired LAN. Just like a LAN, the network

lets users at that location share files, printers and other services.
