Planning Your Wireless Network
Network Topology
A wireless LAN is exactly like a regular LAN , e xcept that each computer in the LAN uses an Instant Wireless™ Network PC Card to connect to the network using no wires. Computers in a wireless LAN must be configured to share the same radio channel.
The Instant Wireless™ Network PC Card provides access to a wired LAN for wireless workstations. An integrated wireless and wired LAN is called an Infrastructure conf iguration. A group of Instant Wireless™ Network PC Card users and an Access Point compose a Basic Service Set (BSS). Each PC equipped with an Instant W ireless™ Network PC Card in a BSS can talk to any computer in a wired LAN infrastructure via the Access Point.
An infrastructure configuration extends the accessibility of an Instant Wireless™ Network PC Card PC to a wired LAN, and doubles the effective wireless transmission range for two Instant Wireless™ Network PC Card PCs. Since the Access Point is able to forward data within its BSS, the effective transmission range in an infrastructure LAN is doubled.
The use of a unique ID in a BSS is essential. All computers that have Instant Wireless™ Network PC Cards configured without roaming options in an inde­pendent BSS must be configured with a BSS ID (that is used in the BSS).
The Wireless LAN Infrastructure conf iguration is appropriate for enterprise­scale wireless access to a central database, or as a wireless application for mobile users.
Infrastructure mode also supports roaming capabilities for mobile users. More than one BSS can be configured as an Extended Ser vice Set (ESS). This con­tinuous network allows users to roam freely within an ESS. All Instant Wireless™ Netw ork PC Card PCs within one ESS must be configured with the same ESS ID and use the same radio channel.
Before enabling an ESS with roaming capability, selecting a feasible radio channel and optimum Access Point position is recommended. Proper Access Point positioning combined with a clear radio signal will greatly enhance per­formance.

CONFIGURATION
The Configuration screen allows you to customize the settings for the Network PC Card, the PCI Adapter, and your wireless network.
The Mode setting determines the architecture of your wireless network. Select
Ad-Hoc or Infrastructure Mode depending on your network type. The Ad- Hoc mode is used for a simple peer-to-peer network and allows the sharing of
local resources only between Network PC Cards without needing a wireless Access Point. The Infrastructure mode allows a wireless network to be inte­grated into an existed, wired network through an Access Point. Infrastructure networks permit roaming between Access Points while maintaining a connec­tion to all network resources.
An acronym for Service Set Identifier, SSID is the unique name shared among all points in a wireless network. The SSID must be identical for all points in the network. It is
case sensitive and must not exceed 32 characters.
The Tx Rate f ield shows the current transfer rate for the Network PC Card. T o optimize performance and range, the TX Rate should be set to Fully Automatic, which will auto­matically adjust the transfer speed for best performance and longest range.
Po w er Sa ving Mode, or PS Mode, enab les or disables the power saving features of your Network PC Card.
The Channelsetting specifies the channel used in wireless communication and should be set to the same channel as the other points in the wireless net­work.This setting can only be adjusted in AdHoc mode.

ENCRYPTION
The 40-bit or 128-bit WEP keys can be generated from a user-defined passphrase or entered manually.
An acronym for Wired Equivalent Privacy, WEP is an encryption scheme used to protect your wireless data communications. WEP uses a combination of 40-bit or 128-bit keys to provide access control to your network and encryption security for every data transmission. To decode a data transmission, each point in a network must use an identical 40-bit or 128-bit key. When using 40-bit encryption, remember that it is identical to and compatible with 60-bit encryption. Higher encryption levels mean higher levels of security, but, due to the complexity of the encryption, they may mean decreased network performance.
Encryption (WEP) can be set to Disabled, 40-bit, or 128-bit. Once enabled, you can create an encryption key by using a Passphrase, or by entering the key manually.
(The Passphrase method is rec- ommended; however, you may need to enter a manual key in order to meet the requirements of existing wireless equipment on your network. If you are unsure, check your other wire­less PCs’settings.)
The Passphrase can be any text string with a maximum of 31 alphanumeric characters and is strongly recommended because it is the easiest way to generate WEP keys.
Once you have chosen your key encryption method and entered either the Passphrase or manual key, click the Apply button. Then click the OK button and the encryption portion of the setup is complete.
Instant WirelessTMSeries
Note: Please make sure that each point in your wireless network is set at an identical WEP value.
Note: Not all Wireless Access Points or Adapters support 128-bit WEP Encryption, which may result in network errors. Check your wireless device’s documentation for more information.

Troubleshooting
This chapter provides solutions to problems usuall y occurring during the instal­lation and operation of the Network PC Card. Read the description below to solve your problems. If you can’t find an answer here, check the Linksys web­site at www.linksys.com.
1.My computer does not recognize the Network PC Card.
• Make sure that the Network PC Card is properly inserted into the PCMCIA slot. Note that the card can be inserted either way, but when it is inserted properly, the “Instant Wireles” logo on the front of the card will not be seen. If seen from the opposite side, only a small portion of the barcode and no numbers can be seen when the card is inserted completely. If in doubt, tr y inserting the card both ways. The card will slide in further when it is correct.
2.The Network PC Card does not work properly.
• Reinsert the Network PC Card into your notebook’s PCMCIA slot. A beep should be heard if the adapter is properly inserted.
• For non-Windows environments, make sure that a PCMCIA card service driver is installed in your PC.
• Click on the Control Panel and then on PC-Card. Check whether it has a PCMCIA card in one of the sockets or not. If you find Network PC Card in one of the sockets, it means the card is detected properly. If you see a yellow question mark, the resources are conflicting. Right click on My Computer and select Properties. Select the device man­ager and click on the Network Adapter. You will find the Network PC Card if it is installed successfully. If you see the yellow exclamation mark, the resources are conflicting. Click on PCMCIA card and then on PCMCIA card service. You will see the status of the Network PC Card. If there is a yellow question mark, please check the following:
• Make sure your notebook supports a 5.0V card.
• Make sure your notebook has a free IRQ.
• Make sure you have inserted the right card and installed the proper driver.
If the Network PC Card does not function after attempting the above steps, remove the card and do the following:
• Uninstall the driver software from your PC.
• Restart your PC and repeat the hardware and software installation as specified in this User Guide.
Common Problems and Solutions
Page 41
What is ISM band?
The FCC and their counterparts outside of the U.S. have set aside bandwidth for unlicensed use in the ISM (Industrial, Scientific and Medical) band. Spectrum in the vicinity of 2.4 GHz, in particular, is being made available worldwide. This presents a truly revolutionary opportunity to place convenient high-speed wireless capabilities in the hands of users around the globe.
What is Spread Spectrum?
Spread Spectrum technology is a wideband radio frequency technique devel­oped by the military for use in reliable, secure, mission-critical communica­tions 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-spectr um signal looks like background noise. There are two main alternatives, Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS).
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, 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.
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.
What is Roaming?
Roaming is the ability of a portable computer user to communicate continu­ously while mo ving freel y throughout an area greater than that co vered b y a sin­gle Access Point. Before using the roaming function, the workstation must make sure that it is the same channel number with the Access Point of dedicat­ed coverage area.
To achieve true seamless connectivity, the wireless LAN must incorporate a number of different functions. Each node and Access Point, for example, must always acknowledge receipt of each message. Each node must maintain contact with the wireless network even when not actually transmitting data. Achieving these functions simultaneously requires a dynamic RF networking technology that links Access Points and nodes. In such a system, the user’ s end node under­takes a search for the best possible access to the system. First, it evaluates such factors as signal strength and quality, as well as the message load currently being carried by each Access Point and the distance of each Access Point to the wired backbone. Based on that information, the node next selects the right Access Point and registers its address. Communications between end node and host computer can then be transmitted up and down the backbone.
As the user moves on, the end nodes RF transmitter regularly checks the sys­tem to determine whether it is in touch with the original Access Point or whether it should seek a new one. When a node no longer receives acknowl­edgment from its original Access Point, it undertakes a new search. Upon find­ing a new Access P oint, it then rere gisters, and the communication process con­tinues.
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.
What is ESS ID?
An Infrastructure configuration could also support roaming capability for mobile workers. More than one BSS can be configured as an Extended Service Set (ESS). Users within an ESS could Roam freely between BSSs while served as a continuous connection to the network wireless stations and Access Points within an ESS must be configured with the same ESS ID and the same radio channel.
