1 Introduction

Thank you for purchasing the 802.11g Turbo Wireless LAN USB Module. This USB Module is designed

to comply with IEEE 802.11g Wireless LAN standard. It enables any devices to operate wirelessly..

This module supports higher data throughput than the IEEE 802.11g standard (up to 54Mbps). It

supports specific ways to increase the data transfer rate at a time; compress the data and decrease the

waiting time to send the next data to the Routers or APs. This feature is called Turbo Mode. When the

module is connecting to the Routers or APs with the proprietary feature, the wireless network will be

more effective.

For WLAN security issues, this module supports 64/128-bit WEP data encryption that protects your

wireless network from eavesdropping. It also supports WPA (Wi-Fi Protected Access) feature that

combines IEEE 802.1x and TKIP (Temporal Key Integrity Protocol) technologies. Client users are

required to authorize before accessing to APs or AP Routers, and the data transmitted in the network is

encrypted/decrypted by a dynamically changed secret key. Furthermore, this module supports WPA2

function, WPA2 provides a stronger encryption mechanism through AES (Advanced Encryption

Standard), which is a requirement for some corporate and government users.

When you use the devices with services such as Voice over Internet Protocol (VoIP) phones,

televisions and MP3 players, how can you speed up the audio, video and voice data to pass through

the wireless network? IEEE 802.11e Quality of Service (QoS) (The Wi-Fi Alliance defined WMM as a

profile of the IEEE 802.11e) extensions for 802.11 networks will help to define the priorities of the data

traffics by the data categories to provide enhanced multimedia support. This module supports the

advanced technology for sure.

activated, the module will be initially connected to the profile.

3.2.1 Configure the Profile

3.2.1.1 Configuration

Parameter Description

Profile Name Define a recognizable profile name for you to identify the different

networks.

SSID The SSID (up to 32 printable ASCII characters) is the unique

name identified in a WLAN. The ID prevents the unintentional

merging of two co-located WLANs.

You may specify a SSID for the module and then only the device

with the same SSID can interconnect to the module. If you want to

add the network nearby to the profile list, pull down the menu, all

the networks will be listed for you to add one of them to the profile

list.

PSM (Power Saving Mode) The power saving function is only available when the network type

is in Infrastructure.

CAM (Constantly Awake Mode) – The module will always set in

active mode.

PSM (Power Saving Mode) – Enable the module in the power

saving mode when it is idle.

Parameter Description

Network Type Infrastructure – This operation mode requires the presence of an

802.11 Access Point. All communication is done via the Access

Point or Router.

Ad-Hoc – Select this mode if you want to connect to another

wireless stations in the Wireless LAN network without through an

Access Point or Router.

TX Power If you want to lower the transmit power of the module for saving the

power of the system, you can select the lower percentages from the

list. The lower power will cause the lower signal strength and the

coverage range.

Preamble The preamble defines the length of the CRC block for

communication among wireless devices. This option is only active

in the Ad Hoc network.

There are two modes including Auto and Long Preamble. If

“Auto“ mode is selected, the module will auto switch the preamble

mode depending on the wireless devices the module is connecting

to.

RTS Threshold Minimum packet size required for an RTS (Request To Send). For

packets smaller than this threshold, an RTS is not sent and the

packet is transmitted directly to the wireless network. Select a

setting within a range of 0 to 2347 bytes. Minor change is

recommended.

Fragment Threshold The value defines the maximum size of packets; any packet size

larger than the value will be fragmented. If you have decreased this

value and experience high packet error rates, you can increase it

again, but it will likely decrease overall network performance. Select

a setting within a range of 256 to 2346 bytes. Minor change is

recommended.

Channel This setting is only available for Ad Hoc mode. Select the number of

the radio channel used for the networking. The channel setting

should be the same with the network you are connecting to.

3.2.1.2 Authentication and Security

Parameter Description

Authentication Type This setting has to be consistent with the wireless networks that

the module intends to connect.

Open – No authentication is needed among the wireless network.

Shared – Only wireless devices using a shared key (WEP Key

identified) are allowed to connecting each other.

LEAP – LEAP is a pre-EAP, Cisco-proprietary protocol, with many

of the features of EAP protocols. Cisco controls the ability of other

vendors to implement this protocol, so it should be selected for

use only when limited vendor choice for client, access-point, and

server products is not a concern. When you have set up LEAP

authentication, you have to enter the user name and password of

your computer.

WPA – WPA provides a scheme of mutual authentication using

either IEEE 802.1x/Extensible Authentication Protocol (EAP)

authentication or pre-shared key (PSK) technology. It provides a

high level of assurance to enterprises, small businesses and

home users that data will remain protected and that only

authorized users may access their networks. For enterprises that

have already deployed IEEE 802.1x authentication, WPA offers

the advantage of leveraging existing authentication databases

and infrastructure.

Parameter Description

WPA-PSK – It is a special mode designed for home and small

business users who do not have access to network authentication

servers. In this mode, known as Pre-Shared Key, the user

manually enters the starting password in their access point or

gateway, as well as in each wireless station in the network.

WPA-PSK takes over automatically from that point, keeping

unauthorized users that don't have the matching password from

joining the network, while encrypting the data traveling between

authorized devices.

WPA2 – Like WPA, WPA2 supports IEEE 802.1x/EAP

authentication or PSK technology. It also includes a new

advanced encryption mechanism using the Advanced Encryption

Standard (AES). AES is required to the corporate user or

government users. The difference between WPA and WPA2 is that

WPA2 provides data encryption via the AES. In contrast, WPA

uses Temporal Key Integrity Protocol (TKIP).

WPA2-PSK – WPA2-PSK is also for home and small business.

The difference between WPA-PSK and WPA2-PSK is that

WPA2-PSK provides data encryption via the AES. In contrast,

WPA-PSK uses Temporal Key Integrity Protocol (TKIP).

WPA-NONE – WPA-NONE is defined for Ad hoc mode and

behaves like WPA-PSK (WPA-PSK is only defined for

infrastructure mode). The user manually enters the Pre-Shared

Key in each wireless station in the network and WPA-NONE

controls unauthorized users that don't have the matching

Pre-Shared Key from joining the network and also encrypts the

data traveling between authorized devices.

802.1x Setting When you have set the Authentication Type to Open, Shared,

WPA or WPA2, you can also enable IEEE 802.1x setting to use

the authentication server or certification server to authenticate

client users.

Encryption Mode None – Disable the encryption mode.

WEP – Enable the WEP Data Encryption. When the item is

selected, you have to continue setting the WEP Encryption keys.

TKIP – TKIP (Temporal Key Integrity Protocol) changes the

temporal key every 10,000 packets (a packet is a kind of message

transmitted over a network.) This ensures much greater security

than the standard WEP security.

Parameter Description

AES – AES has been developed to ensure the highest degree of

security and authenticity for digital information and it is the most

advanced solution defined by IEEE 802.11i for the security in the

wireless network.

Note: All devices in the network should use the same encryption

method to ensure the communication.

WPA Pre-Shared Key The WPA-PSK key can be from 8 to 64 characters and can be

letters or numbers. This same key must be used on all of the

wireless stations in the network.

WEP Key

(Key1 ~ Key4)

The WEP keys are used to encrypt data transmitted in the

wireless network. There are two types of key length: 64-bit and

128-bit. Select the default encryption key from Key 1 to Key 4 by

selected the radio button.

Fill the text box by following the rules below.

64-bit – Input 10-digit Hex values (in the “A-F”, “a-f” and “0-9”

range) or 5-digit ASCII characters (including “a-z” and “0-9”) as

the encryption keys. For example: “0123456aef“ or “test1”.

128-bit – Input 26-digit Hex values (in the “A-F”, “a-f” and “0-9”

range) or 13-digit ASCII characters (including “a-z” and “0-9”) as

the encryption keys. For example:

“01234567890123456789abcdef“ or “administrator”.

The IEEE 802.1X specification describes a protocol that can be used for authenticating both clients and

servers on a network. The authentication algorithms and methods are those provided by the Extensible

Authentication Protocol (EAP), a method of authentication that has been in use for a number of years

on networks that provide Point-to-Point Protocol (PPP) support as many internet service providers and

enterprises do.

When an AP acting as an authenticator detects a wireless station on the LAN, it sends an EAP-Request

for the user's identity to the device. (EAP, or the Extensible Authentication Protocol, is an authentication

protocol that runs before network layer protocols transmit data over the link.) In turn, the device

responds with its identity, and the AP relays this identity to an authentication server, which is typically

an external RADIUS server.

3.2.1.3 802.1x Setting-Certification

Parameter Description

Authentication Type The EAP authentication protocols this module has supported are

included as follows. This setting has to be consistent with the

wireless APs or Routers that the module intends to connect.

PEAP &TTLS – PEAP and TTLS are similar and easier than TLS

in that they specify a stand-alone authentication protocol be used

within an encrypted tunnel. TTLS supports any protocol within its

tunnel, including CHAP, MS-CHAP, MS-CHAPv2, PAP and

EAP-MD5. PEAP specifies that an EAP-compliant authentication

protocol must be used; this module supports EAP-MSCHAP v2,

EAP-TLS/Smart Card and Generic Token Card. The client

certificate is optional required for the authentication.

TLS/Smart Card –TLS is the most secure of the EAP protocols

but not easy to use. It requires that digital certificates be

exchanged in the authentication phase. The server presents a

certificate to the client. After validating the server’s certificate, the

client presents a client certificate to the server for validation.

Session Resumption There are “Disabled”, “Reauthentication”, “Roaming”, “SameSsid”

and “Always” selections for you to choose whether to recovery the

session in different status.

Password Enter the password as the identity for the server.

Use Client Certificate

client certificate is required for TLS, and is optional for TTLS and

PEAP. This forces a client certificate to be selected from the

appropriate Windows Certificate Store and made available to the

RADIUS server for certification.

Tunneled Authentication

Protocol When the authentication type is PEAP or TTLS, select a protocol

to be used to build the encrypted tunnel.

Identity This is the protected user EAP Identity used for authentication.

The identity specified may contain up to 63 ASCII characters, is

case sensitive and takes the form of a Network Access Identifier,

consisting of <name of the user>@<user’s home realm>. The

user’s home realm is optional and indicates the routing domain.

Password The password used for authentication. It may contain up to 63

ASCII characters and is case sensitive.

3.2.1.4 802.1x Setting-CA Server

Parameter Description

Use Certificate Chain When the EAP authentication type such as TLS, TTLS or PEAP is

selected and required a certification to tell the client what server

credentials to accept from the authentication server in order to

verify the server, you have to enable this function.

Certificate Issuer Choose the server from the list to issue the certificate. If “Any

Trusted CA” is selected, any CA included in the list (provided by

the Microsoft Certificate Store) is permitted.

Allow Intermediate Certificates A server designates an issuer as a trusted root authority by

placing the issuer's self-signed certificate, which contains the

issuer's public key, into the trusted root certification authority

certificate store of the host computer. Intermediate or subordinate

certification authorities are trusted only if they have a valid

certification path from a trusted root certification authority.

Server Name Enter the authentication server name.

Server name must match exactly When selected, the server name must match exactly the server

name found on the certificate.

Domain name must end in

specified name

When selected, the server name field identifies a domain. The

certificate must use a server name belonging to this domain or to

one of its sub-domains (e.g. zeelans.com, where the server is

blueberry.zeelans.com) but it may be any name used in the

certificate name field.

3.3 Link Status

LEAP authentication, including communication with the main

RADIUS server.

When you configure your wireless LAN for fast re-association,

however, LEAP-enabled client devices roam from one access

point to another without involving the main server. Using Cisco

Centralized Key Management (CCKM), an access point configured

to provide Wireless Domain Services (WDS) takes the place of the

RADIUS server and authenticates the client so quickly that there is

no perceptible delay in voice or other time-sensitive applications.

4 Glossary

This chapter provides solutions to problems usually encountered during the installation and operation

of the module.

1. What is the IEEE 802.11g standard?

802.11g is the new IEEE standard for high-speed wireless LAN communications that provides for

up to 54 Mbps data rate in the 2.4 GHz band. 802.11g is quickly becoming the next mainstream

wireless LAN technology for the home, office and public networks.

802.11g defines the use of the same OFDM modulation technique specified in IEEE 802.11a for

the 5 GHz frequency band and applies it in the same 2.4 GHz frequency band as IEEE 802.11b.

The 802.11g standard requires backward compatibility with 802.11b.

The standard specifically calls for:

A. A new physical layer for the 802.11 Medium Access Control (MAC) in the 2.4 GHz frequency

band, known as the extended rate PHY (ERP). The ERP adds OFDM as a mandatory new

coding scheme for 6, 12 and 24 Mbps (mandatory speeds), and 18, 36, 48 and 54 Mbps

(optional speeds). The ERP includes the modulation schemes found in 802.11b including

CCK for 11 and 5.5 Mbps and Barker code modulation for 2 and 1 Mbps.

B. A protection mechanism called RTS/CTS that governs how 802.11g devices and 802.11b

devices interoperate.

2. What is the IEEE 802.11b standard？

The IEEE 802.11b Wireless LAN standard subcommittee, which formulates the standard for the

industry. The objective is to enable wireless LAN hardware from different manufactures to

communicate.

3. What does IEEE 802.11 feature support？

The product supports the following IEEE 802.11 functions:

z CSMA/CA plus Acknowledge Protocol

z Multi-Channel Roaming

z Automatic Rate Selection

z RTS/CTS Feature

z Fragmentation

z Power Management

4. What is Ad-hoc？

An Ad-hoc integrated wireless LAN is a group of computers, each has a Wireless LAN module,

Connected as an independent wireless LAN. Ad hoc wireless LAN is applicable at a

departmental scale for a branch or SOHO operation.

5. What is Infrastructure？

An integrated wireless and 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.

6. 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.

7. 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 standard.

8. What is TKIP?

TKIP is a quick-fix method to quickly overcome the inherent weaknesses in WEP security,

especially the reuse of encryption keys. TKIP is involved in the IEEE 802.11i WLAN security

standard, and the specification might be officially released by early 2003.

9. What is AES?

AES (Advanced Encryption Standard), a chip-based security, has been developed to ensure the

highest degree of security and authenticity for digital information, wherever and however

communicated or stored, while making more efficient use of hardware and/or software than

previous encryption standards. It is also included in IEEE 802.11i standard. Compare with AES,

TKIP is a temporary protocol for replacing WEP security until manufacturers implement AES at

the hardware level.

10. Can Wireless products support printer sharing？

Wireless products perform the same function as LAN products. Therefore, Wireless products can

work with Netware, Windows 2000, or other LAN operating systems to support printer or file

sharing.

11. 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.

12. 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 is, 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.

13. What is Spread Spectrum？

Spread Spectrum technology is a wideband radio frequency technique developed by the military

for use in reliable, secure, mission-critical communication 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).

14. What is WMM？

Wi-Fi Multimedia (WMM), a group of features for wireless networks that improve the user

experience for audio, video and voice applications. WMM is based on a subset of the IEEE

802.11e WLAN QoS draft standard. WMM adds prioritized capabilities to Wi-Fi networks and

optimizes their performance when multiple concurring applications, each with different latency

and throughput requirements, compete for network resources. By using WMM, end-user

satisfaction is maintained in a wider variety of environments and traffic conditions. WMM makes it

possible for home network users and enterprise network managers to decide which data streams

are most important and assign them a higher traffic priority.

15. What is WMM Power Save？

WMM Power Save is a set of features for Wi-Fi networks that increase the efficiency and

flexibility of data transmission in order to conserve power. WMM Power Save has been optimized

for mobile devices running latency-sensitive applications such as voice, audio, or video, but can

benefit any Wi-Fi device. WMM Power Save uses mechanisms included in the IEEE 802.11e

standard and is an enhancement of IEEE 802.11 legacy power save. With WMM Power Save,

the same amount of data can be transmitted in a shorter time while allowing the Wi-Fi device to

remain longer in a low-power “dozing” state.
