PURE NETWORKING 802.11G WIRELESS PCI ADAPTER

2. Introduction

2.1 Overview

The Pure Networking 802.11g Wireless PCI Adapter is used to attach a PC to

another network device using wireless technology to transfer data. It complies with

the IEEE 802.11g standard, which supports high-speed wireless network

connections up to 54 Mbps. It can also work with IEEE 802.11b devices. When the

adapter connects to 11b devices, maximum link speed is 11 Mbps.

High throughput supports multimedia data bandwidth, and 64-/128-/152-bit WEP,

WPA (TKIP [Temporal Key Integrity Protocol] with IEEE 802.1x), and AES

functions for a high level of security. Client users are required to get authorization

before connecting to access points (APs) or AP routers, and the data transmitted in

the network is encrypted/decrypted by a dynamically changed secret key.

Automatic fallback also increases data security and reliability.

The adapter works with Windows 98 SE/Me/XP, Windows 2000, and Linux, and it

supports a 32-bit PCI interface.

Two power-saving features make the adapter particularly efficient. First, the

adapter’s power consumption is very low. Second, you can control how long the

adapter’s attached devices’ power stays on. Simply set the time (in minutes) that

your portable or handheld devices wait before powering off.

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 2312 bytes. We recommend

changing the size in small increments.

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 2312 bytes. We

recommend changing the size in small increments.

networks that the card intends to connect to.

None—No authentication is needed among the wireless

networks.

Shared—Only wireless stations using a shared key (WEP

Key identified) are allowed to connect to each other.

WPA-PSK—This 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, manually enter the starting password in

the access point or gateway, as well as in each wireless

station in the network. WPA takes over automatically from

that point, keeping unauthorized users that don’t have a

matching password from joining the network while

encrypting the data traveling between authorized devices.

The encryption methods include TKIP and AES. This

option is only available for Windows XP.

Encryption Type None—Disable the WEP Data Encryption.

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

message transmitted over a network.) This ensures much

greater security than the standard WEP security.

CHAPTER 4: Configuration Utility

NOTE

All devices in the network should use the same encryption method to

ensure proper communication.

NABLE

WPA

INDOWS

In the Profiles screen (see Figure 4-5), there’s an option for WPA Pre-Shared Key

(described in Table 4-4). When you’re using Windows XP, you can enable this

option. Here’s what it does: Wi-Fi Protected Access (WPA) is a standards-based,

interoperable specification for security enhancement that strongly increases the

level of data protection (encryption) and access control (authentication) for

existing and future wireless LAN systems. The technical components of WPA

include Temporal Key Integrity Protocol (TKIP) for dynamic key exchange, and

802.1x for authentication.

There are two types of WPA security: WPA-PSK (no server) and WPA (with server).

WPA requires a radius server to complete the authentication among wireless

stations and access points. Typically, this mode is used in a enterprise environment.

WPA-PSK uses a so-called pre-shared key as the security key. A pre-shared key is a

password that each wireless station uses to access the network. Typically, this mode

will be used in a home environment.

To enable the WPA function in Windows XP, the following software systems are

required: Windows XP Service Pack 1 with Windows XP Support Patch for Wi-Fi

Protected Access program. Follow the steps below to use WPA.

1. Configure the card by the wireless built-in utility (Wireless Zero

Configuration). See Figures 4-6 and 4-7.

NOTE

When WPA is enabled, there are two utility selections (either RaConfig

or Wireless Zero Configuration) when you open the card’s Configuration

Utility (see Figure 4-6). Select the XP built-in utility with full WPA

function. If you select XP Wireless Zero Configuration, you can only

configure the Advance setting or check the Link Status and Statistics

from the RaConfig utility. From Figure 4-6, click on OK to save your

selection.

Figure 4-6. Selecting the utility.

CHAPTER 4: Configuration Utility

2. Once you click on OK, the Wireless Network Connection screen appears (see

Figure 4-7). From here, right-click the icon to select View Available Wireless

Networks.

3. Click on the Advanced button from the screen shown in Figure 4-7.

Figure 4-7. Selecting the wireless network.

4. The screen refreshes with the Wireless Networks tab highlighted (see Figure

4-8). In this screen, click on the Configure button to configure the WPA

function for the current network.

NOTE

Uncheck “Use Windows to configure my wireless network settings,” and

the RaConfig utility will be enabled again.

Parameter Description

Network name (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.

Network Authentication Open—No authentication is needed among the wireless

networks.

Shared—Only wireless stations using a shared key (WEP

Key identified) are allowed to connect to each other.

WPA—This mode is for an enterprise network with an

authentication server (radius server), WPA-enabled

access point, and a WPA-enabled client. Once WPA is

enabled, all clients and access points on the network

must be WPA-enabled in order to access the network.

WPA-PSK—This 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, manually enter the starting password in

the access point or gateway, as well as in each PC on the

wireless network. WPA 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.

Data Encryption WEP—In WPA or WPA-PSK mode, WEP is also able to

be the encryption method for the transmission data.

TKIP—TKIP (Temporal Key Integrity Protocol) changes

the temporal key every 10,000 packets (a packet is a

message transmitted over a network). This ensures much

greater security than the standard WEP security.

Table 4-7. Advance parameters.

Parameter Description

Wireless Mode 802.11 B/G mix—If you have a mix of 802.11b and

802.11g wireless stations in your network, we recommend

setting the card to this mode. This mode is also the

default setting.

802.11 B only—This card can be compatible with both

802.11g and 802.11b wireless stations. If there are only

802.11b wireless stations in the network, set the card to

this mode.

Tx BURST Tx Burst enables the card to deliver better throughput in

the same period and environment.

B/G Protection If you have a mix of 802.11b and 802.11g wireless

stations in the network, enable the protection mechanism.

This mechanism can decrease the rate of data collision

between 802.11b and 802.11g wireless stations. When

the protection mode is enabled, the card’s throughput will

be a little lower since much of the frame traffic is

transmitted.

Auto—Based on the network’s status, automatically

disables/enables protection mode.

On—Always enables the protection mode.

Off—Always disables the protection mode.

ADHOC_OFDM When the network type is in ad-hoc mode, the card can

only work in the 11b data rate. It is defined by the Wi-Fi

organization. If you want to enable the data rate up to

54 Mbps (11g), select ADHOC_OFDM.

CHAPTER 4: Configuration Utility

Parameter Description

Tx Rate There are several options including Auto, 1, 2, 5.5, 11, 6,

9, 12, 18, 24, 36, 48, 54 Mbps. When Auto is selected, the

device will choose the most suitable transmission rate

automatically. The higher the data rate you designate in

the network, the shorter the distance allowed between the

card and the wireless stations.

When the wireless mode is 802.11 B only, the maximum

data rate is 11 Mbps (11b). Auto, 1, 2, 5.5, and 11 Mbps

are the available options.

5.1 Frequently Asked Questions

1. What is the IEEE 802.11g standard?

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

communications that provides a data rate of up to 54 Mbps 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 formulates the

standard for the industry. The objective is to enable wireless LAN hardware

from different manufacturers to communicate.

3. What does the IEEE 802.11 feature support?

The product supports the following IEEE 802.11 functions:

• CSMA/CA plus Acknowledge Protocol

• Multi-Channel Roaming

• Automatic Rate Selection

• RTS/CTS Feature

• Power Management

4. What is Ad-hoc?

An ad-hoc integrated wireless LAN is a group of computers linked to each

other without using an access point; each has a Pure Networking 802.11g

Wireless PCI Adapter connected as an independent wireless LAN. You’d

typically use an ad-hoc wireless LAN for a branch or SOHO operation.

5. What is infrastructure?

When you connect a wireless LAN and a combination (wireless and wired)

LAN together, it’s called an infrastructure configuration. Infrastructure is

applicable on an enterprise scale for wireless access to a central database, or

for a 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.

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. Compared with AES,

TKIP is a temporary protocol for replacing WEP security until manufacturers

implement AES at the hardware level.

CHAPTER 5: Troubleshooting

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).
