Chapter 1 Introduction of IEEE 802.11 Wireless Adapter 1-1 Introducing the LAN-Express IEEE 802.11 Wireless Adapter LAN-Express IEEE 802.11 Wireless Adapter is a high performance wireless LAN adapter that complies with the IEEE 802.11b and 802.11g wireless standards, which can be used with 802.11b or 802.11g devices to form a stand-alone wireless Peer-to-Peer Group* or used in conjunction with an Access Point infrastructure to provide mobile clients with wireless access to an Ethernet network. The LAN-Express IEEE 802.11 Wireless Adapter supports Windows XP, Windows 2000, Windows Millennium Edition (ME), and Windows 98. A wireless LAN provides the same functionality of a wired network, but it eliminates the need to install networking cables and other networking equipment. A wireless LAN is not only easier to deploy, but it also allows for mobility through roaming. For example, the LAN-Express IEEE 802.11 Wireless Adapter can roam from a conference room to an office without being disconnected from the network.

*Available features vary by region/country. 1-2 Specifications & System Requirements You must meet the following minimum requirements in order to begin using an LAN-Express IEEE 802.11 Wireless Adapter,

Windows XP, Windows 2000, Windows Millennium Edition (ME), or Chapter 1 Instruction of IEEE 802.11 Wireless Adapter 5 LAN-Express IEEE 802.11 Wireless Adapter User Guide Windows 98 Second Edition (SE) installed

PC Card expansion slot (32-bit CardBus) for LAN-Express IEEE 802.11 Wireless Adapter

32-bit PCI bus slot on your desktop for the LAN-Express IEEE 802.11 Wireless Adapter.

At least 64 MB of memory

A 300 MHz processor or higher

At least one other IEEE 802.11b-compliant or 802.11g-compliant device 1-2-1 IEEE 802.11 Specifications The Institute of Electrical and Electronics Engineers (IEEE) adopted the 802.11 standard for wireless devices operating in the 2.4 GHz frequency band in 1997. This standard includes provisions for three radio technologies: direct sequence spread spectrum, frequency hopping spread spectrum, and infrared. Devices that comply with the 802.11 standard operate at a data rate of either 1 or 2 Mbps. 802.11b In 1999, the IEEE modified the 802.11 standard to support direct sequence devices that can operate at speeds of up to 11 Mbps. The IEEE ratified this standard as 802.11b. 802.11b devices are backwards compatible with 2.4 GHz 802.11 direct sequence devices

(that operates at 1 or 2 Mbps). 802.11a Also in 1999, the IEEE modified the 802.11 standard to support devices operating in the 5 GHz frequency band. This standard is referred to as 802.11a. 802.11a devices are not backward compatible with 2.4 GHz 802.11 or 802.11b devices. 802.11a radios use a radio technology called Orthogonal Frequency Division Multiplexing (OFDM) to achieve data rates of up to 54 Mbps. 802.11g In 2003, the IEEE ratified the 802.11g standard. This standard delivers the same 54Mbps maximum data rate as 802.11a, yet it offers an additional and compelling advantage-backward compatibility with 802.11b equipment. This means that 802.11b Chapter 1 Instruction of IEEE 802.11 Wireless Adapter 6 LAN-Express IEEE 802.11 Wireless Adapter User Guide client cards will work with 802.11g access points, and 802.11g client cards will work with 802.11b access points. Note that 802.11b products cannot be upgraded to support 802.11g since the 802.11g radios use a different chipset than 802.11b devices. However, 802.11g products and 802.11b products can work in the same network. Because 802.11g and 802.11b operate in the same unlicensed band, the two standards share the same three channels, which can limit wireless capacity and scalability. An 802.11a device and an 11b/g device cannot communicate with each other. The Wi-Fi standard certified at 2.4 GHz ensures the wireless interoperability with other Wi-Fi (802.11b) certified devices. 1-2-2 Security Standards The LAN-Express IEEE 802.11 Wireless Adapter supports the following security standards (features vary based on models):

Cisco Client Extension compatibility (including LEAP)

Wired Equivalent Privacy (WEP) encryption using 64 bit, 128 bit or 152 bit encryption

AES-CCM Encryption support

Support for Windows 802.1x supplicants

Wi-Fi Protected Access (WPA) encryption using PassPhrase (text string with at least 8 to 63 characters, it can be any combination of letters, numbers and other characters).

Figure 2-12 Un-installation and Maintenance Completed Chapter 3 Wireless Topologies 18 LAN-Express IEEE 802.11 Wireless Adapter User Guide Chapter 3 Wireless Topologies LAN-Express IEEE 802.11 Wireless Adapter looks and operates similar to Ethernet products. The only difference is that a radio replaces the wire between communicating devices. This means that all of your existing applications that operate over Ethernet will work with the LAN-Express IEEE 802.11 Wireless Adapter without any special wireless networking software. A wireless LAN can be configured for two different modes of operation. While each method has its advantages, one of them may be better suited for your needs. Review the following configurations to determine which mode is best for you. 3-1 Peer-to-Peer Group A Peer-to-Peer groupalso known as an Ad-Hoc network-- is the simplest to deploy and is ideal for small offices. Peer-to-Peer Group can be comprised of two or more wireless client configured to communicate with one another. Peer-to-Peer Group clients communicate directly with each other without using an access point (AP). As a user on this type of network, you are able to quickly build up a wireless network in order to share files with other employees, print to a shared office printer, and access the Internet through a single shared connection. Ad-hoc networking is cost effective, because no other devices components are needed

(such as access points, hubs or routers) in order to setup a network. However, with Ad-Hoc networking, your computer is only able to communicate with other nearby Chapter 3 Wireless Topologies 19 LAN-Express IEEE 802.11 Wireless Adapter User Guide wireless clients. By using the off-the-shelf peer-to-peer network operating systems, each computer can dynamically connect and reconnect to the others with no additional configuration, as illustrated in Figure 3-1. Figure 3-1 Peer-to-Peer Group The LAN-Express IEEE 802.11 Wireless Adapter can communicate with an 802.11b or 802.11g Peer-to-Peer Group (but it can not dynamically switch between the two). Therefore, you must manually configure the wireless adapter to use one specific radio mode. 3-2 Access Point Infrastructure Many companies have an existing Ethernet or wired LAN infrastructure and want to be able to extend that capability to wireless nodes. This is accomplished by installing one or more Access Points on the Ethernet network. Access Points are devices that communicate with both the Ethernet network and the wireless network. Chapter 3 Wireless Topologies 20 LAN-Express IEEE 802.11 Wireless Adapter User Guide An Access Point network is also referred to as an Infrastructure network. The key difference between an Infrastructure network and an Ad-Hoc network is the addition of one extra elementthe Access Point. The Access Point serves as the focal point for all data traffic on your wireless network, optimally managing all wireless data transactions. Additionally, the wireless Infrastructure can provide access to an existing wired LAN. This link allows computers on the wireless LAN to access the other wired LANs resources and tools, including Internet access, email delivery, file transfer, and printer sharing. See figure 3-2 for example. Figure 3-2 Access Point Network You can use the LAN-Express IEEE 802.11 Wireless Adapter to communicate with 802.11g Access Points, 802.11b Access Points, or a combination of Access Point types. The wireless adapter is compatible with 802.11g and 802.11b Access Points from any vendor. Chapter 3 Wireless Topologies 21 LAN-Express IEEE 802.11 Wireless Adapter User Guide 3-2-1 Roaming Among Multiple APs For larger environments, the LAN-Express IEEE 802.11 Wireless Adapter may roam from one Access Point to another while maintaining the same network connection. The Access Points establish coverage areas or cells similar in concept to those of a cellular phone network. The card will connect to any Access Point that is within range. The LAN-Express IEEE 802.11 Wireless Adapter supports both roaming between APs of the same type (for example, from one 802.11b AP to another) and roaming between APs of different types (for example, from an 802.11b AP to an 802.11g AP). Figure 3-2 illustrates roaming between APs of different radio types:

Figure 3-2 Roaming Between APs of Different Radio Types As the mobile client seamlessly switches from cell to cell, its network connectivity is preserved. The user can move freely between the Access Points in the network. When the roaming client leaves the transmission range of one Access Point, the card automatically detects the other Access Point(s) in the same vicinity to continue the network connection. Chapter 3 Wireless Topologies 22 LAN-Express IEEE 802.11 Wireless Adapter User Guide 3-2-2 Roaming Principles A LAN-Express IEEE 802.11 Wireless Adapter can roam between 802.11g Access Points and 802.11b Access Points. All 802.11b and 802.11g Access Points that a client will roam between must have the same Network Name. Depending on the Wireless Mode selection, a user can roam among 802.11g and 802.11b Access Points. All workstations with LAN-Express IEEE 802.11 Wireless Adapter installed must use either a Network Name of any or the same Network Name as the Access Points that they will roam between. All Access Points and LAN-Express IEEE 802.11 Wireless Adapter must have the same security settings to communicate. The Access Points cells must overlap to ensure that there are no gaps in coverage and to ensure that the roaming client will always have a connection available. Access Points installed in the same vicinity that use the same frequency band (2.4 GHz) should each use a unique, independent Channel to avoid potential interference. Access Points that use the same Channel should be installed as far away from each other as possible to reduce potential interference.

Click OK to save the profile. 4-3-2 Security Settings under Profile Management Mode The Security tab allows you to configure the LAN-Express IEEE 802.11 Wireless Adapter to match the security settings of the Wireless LAN network. Refer to Figure 4-9 for an example. Select the appropriate security mode:

WPA Wi-Fi Protected Access mode allows for the authentication and interoperability with enterprise class WPA enabled networks. This feature allows for authentication with networks that support the EAP-TLS or PEAP Extensible Authentication Protocol (EAP) types. WPA-PSK Wi-Fi Protected Access, Pre-Shared Key mode allows you to use WPA style authentication and encryption in a network that does not support EAP/802.1x authentication. 802.1x - This security mode allows the authentication of the user and/or the station to create a dynamic Wired Equivalent Key (WEP) key. LEAP authentication with a Cisco network infrastructure is included in this mode selection. Other EAP types supported by this mode are EAP-TLS and PEAP. Pre-Shared Key - This mode is commonly referred to as IEEE 802.11 Wired Equivalent Privacy (WEP) encryption. Chapter 4 Wireless Client Utility Configuration 31 LAN-Express IEEE 802.11 Wireless Adapter User Guide None - Use this mode when there is no authentication or encryption enabled on the Wireless LAN network. Figure 4-9 Security Setting under Profile Management Mode Setting Pre-Shared Keys You can define the Pre-Shared keys (Figure 4-10) by using the Define Pre-Shared Keys box. Chapter 4 Wireless Client Utility Configuration 32 LAN-Express IEEE 802.11 Wireless Adapter User Guide Figure 4-10 Defined Pre-Shared Keys Screen Key Entry Method Determines the entry method for an encryption key:

Hexadecimal (0-9, A-F)

ASCII text (any keyboard characters, A-Z, 0-9) Per User Key Defines the unique encryption key for network configuration security. The Per User key is used with many authentication mechanism and encryption. It is also known as a Per-Station key, this key must match the WEP key stored on the access point for this particular device. This allows for data only for this device to be encrypted by its own unique key. If this key is used, one of the shared keys must also be defined for multicast messages between the access point and the device. Multicast messages are those messages that are not sent to a particular station, but all the stations on a particular network. Shared Keys Also known as Group keys, these keys must match the WEP key(s) stored on the access point. While four keys can be entered at the same time, only one can be used to encrypt data going to and coming from the access point. Select one of the radio buttons on the left edge to set the currently active encryption key. At least one Shared Key field must be Chapter 4 Wireless Client Utility Configuration 33 LAN-Express IEEE 802.11 Wireless Adapter User Guide entered to enable security using a shared key. If more then one key is defined then click the appropriate radio button to select a key as the default encryption key. Key Length The options for Key Length are

64 bit encryption (10 digits in HEX mode)

128 bit encryption (26 digits in HEX mode)

152 bit encryption (32 digits in HEX mode) The number of characters that may be entered in the encryption key field will be automatically determined by the Key length setting. Setting WPA PassPhrase Encryption WPA is a new standard-based wireless security solution developed by the Wi-Fi Alliance. WPA also supports the WEP (Wired Equivalent Privacy) security standard. Microsoft provides a security patch called Windows XP Support Patch for Wireless Protected Access on its website for free download and it works only with Windows XP. The WPA encryption is supported on Windows XP Professional and Windows XP Home Edition. There are two types of WPA security:

WPA-PSK (with no server) it uses the so-called pre-shared key as the security key. A pre-shared key is basically a password that is between eight and 63 characters long. It can be any combination of letters, numbers, and other characters. This is the typical mode that is used in a home environment. WPA-PSK is a lightweight 802.1x type authentication that uses a shared secret ASCII based passphrase known by both the access point and station. To enable WPA with a passphrase (WPA-PSK), select WPA-PSK from the Security Options list and click OK to configure as shown in Figure 4-11. WPA (with server) it is a system where a RADIUS server distributes the keys to the clients automatically. It is typically used in a business environment. Chapter 4 Wireless Client Utility Configuration 34 LAN-Express IEEE 802.11 Wireless Adapter User Guide Figure 4-11 Define with a PassPhase The Define WPA PSK screen appears as shown in Figure 4-12. Enter your passphrase text strings to complete the configuration process. For WPA Passphrase, input the ASCII based secret passphrase. The passphrase must be more than 8 characters, but less than 64 characters. Figure 4-12 Define WPA PassPhrase Chapter 4 Wireless Client Utility Configuration 35 LAN-Express IEEE 802.11 Wireless Adapter User Guide Dynamic Security Authentication Setting The Dynamic Security setting prevents unauthorized network access; a network RADIUS server must authenticate each user before the access was granted to the network. To configure the Dynamic Security settings for a particular profile, select WPA or 802.1x mode. You can select TLS or PEAP from the drop-down menu WPA EAP Type if you wish to enable the WPA function, or select TLS, PEAP, or LEAP from the 802.1x EAP Type with no WPA function enabled. The LEAP mode can only been shown in the 802.1x EAP Type drop-down menu, because the WPA does not apply to the LEAP function. When selected, click the Configure button to configure the settings described below.

Chapter 5 Troubleshooting The LAN-Express 802.11 Wireless Adapter is designed to be very easy to install and operate. However, if you experience any difficulties, use the information in this chapter to help diagnose and solve the problem. 5-1 Common Installation Problems Chapter 2 Installation describes how to install an LAN-Express IEEE 802.11 Wireless Adapter in a computer running Windows 98 Second Edition (SE), Windows Millennium Edition (ME), Windows 2000, or Windows XP. This section provides suggestions to resolve some of the common installation problems with a LAN-Express 802.11 Wireless Adapter. 5-1-1 Card Not Installed Properly If Windows Networking reports that the LAN-Express IEEE 802.11 Wireless Adapter has not been properly installed or configured after you have completed the Installation program, open the Device Manager (found within the Control Panels System icon) and locate the cards entry in the Network adapters category. If a yellow exclamation point

(!) appears next to the cards Device Manager entry, then the card is not working properly. Follow these steps:

Chapter 5 Troubleshooting 57 LAN-Express IEEE 802.11 Wireless Adapter User Guide Uninstall the card as described in Chapter 2 Installation. Reinstall the card following the instructions in Chapter 2 Installation. 5-2 Configuring Networking Clients and Protocols An LAN-Express 802.11 Wireless Adapter will bind to any existing networking components, such as Client for Microsoft Networks and the Internet Protocol (TCP/IP). Refer to the steps below that correspond to your computers operating system to configure the cards networking components. 5-2-1 Windows XP/2000 Follow these steps to configure the cards networking clients and protocols in a Windows XP or 2000 computer:

Open the Control Panels Network and Dial-up Connections (Windows 2000) or Network Connections (Windows XP) icon. Scroll through the list of network connections and right-click the Local Area Connection that corresponds to the LAN-Express 802.11 Wireless Adapter. Select Properties from the drop-down menu to view the connections properties screen. Select a client or protocol from the list of components and click Properties to configure its settings. For example, if you want to assign the card a static IP address, highlight Internet Protocol (TCP/IP) and click Properties. To add a new client or protocol, click Install... and follow the on-screen instructions. Chapter 5 Troubleshooting 58 LAN-Express IEEE 802.11 Wireless Adapter User Guide 5-2-2 Windows ME/98 SE Follow these steps to configure a cards networking clients and protocols in a Windows 98/ME computer:

Open the Control Panels Network icon. Select a client or protocol from the list of installed components and click Properties to configure its settings. For example, if you want to assign the LAN-Express 802.11 Wireless Adapter a static IP address, highlight TCP/IP or TCP/IP -> LAN-Express 802.11 Wireless Adapter and click Properties. To add a new client or protocol, click Add... and follow the on-screen instructions. 5-3 Range Every environment is unique with different obstacles, barriers, materials, etc., and, therefore, it is difficult to determine the exact range that will be achieved without testing. Radio signals may reflect off of some obstacles or be absorbed by others depending on their construction. The IEEE 802.11 standards support multiple data rates that correspond to different transmission techniques. For wireless devices, there is a trade-off between range and data rate. Transmission techniques that provide high data rates operate over short distances;

techniques that provide slower data rates operate over greater distances. By default, the LAN-Express 802.11 Wireless Adapter automatically switches between these data rates to maintain a usable radio connection and achieve the best data rate based on the cards Chapter 5 Troubleshooting 59 LAN-Express IEEE 802.11 Wireless Adapter User Guide distance from the Access Point. Therefore, a client that is close to an Access Point will operate at a higher data rate than a client that is farther away from the Access Point. The LAN-Express 802.11 Wireless Adapter includes two integral omni-directional antennas. Note that the coverage footprint of the cards antennas will vary depending on the laptops design and the location of the CardBus slot in the computer. Two antennas are provided to support antenna diversity, a technique which can improve system reliability. Due to the characteristics of radio waves, it is possible that one antenna may provide better performance than a second antenna installed a short distance away. Proper antenna placement can help improve range. Here are some guidelines:

Try to keep the cards antennas free of obstructions (particularly metal objects) and do not place a sheet of metal (like a filing cabinet) between the antennas of two 802.11 devices. Use the Wireless Client Utility to evaluate the signal strength and link quality between 802.11 devices. Refer to the documentation that came with your Access Points for suggestions on how to locate the AP and its antennas to maximize range and performance. 5-4 LED Indicators The LAN-Express 802.11 Wireless Adapter includes two round, green LED indicators on the end of the card. One is for power on/off status, and the other is for activity status. These LEDs display the following behavior:

1. Both LEDs are off when the card is not receiving power or when the driver is not installed. 2. The LEDs blink in an alternating pattern to indicate that the card is searching for an Chapter 5 Troubleshooting 60 LAN-Express IEEE 802.11 Wireless Adapter User Guide Access Point or Peer-to-Peer Group to communicate with. 3. The LEDs blink in unison when the card has associated with an Access Point or joined a Peer-to-Peer Group. 4. When there is network activity, the LEDs blink at a faster rate; the LEDs will blink in unison more often as the cards Transmit or Receive Rate increases. 5. The activity LED turns off when the radio is disabled. 6. After installing the LAN-Express 802.11 Wireless Adapter in a computer, you can check the behavior of the LED indicators when the computer cover is open. The PWR LED is on when the computer is turned on. The RF LED (radio) is on when roaming, connecting to an AP, and transmitting and receiving packets.
