3Chapter 2: Planning your Wireless NetworkNetwork TopologyWireless-G Notebook Adapter with RangeBoosterChapter 2: Planning your Wireless NetworkNetwork TopologyA wireless network is a group of computers, each equipped with one wireless adapter. Computers in a wireless network must be configured to share the same radio channel. Several PCs equipped with wireless cards or adapters can communicate with one another to form an ad-hoc network.Linksys wireless adapters also provide users access to a wired network when using an access point or wireless router. An integrated wireless and wired network is called an infrastructure network. Each wireless PC in an infrastructure network can talk to any computer in a wired network infrastructure via the access point or wireless router.An infrastructure configuration extends the accessibility of a wireless PC to a wired network, and can double the effective wireless transmission range for two wireless adapter PCs. Since an access point is able to forward data within a network, the effective transmission range in an infrastructure network can be doubled.RoamingInfrastructure mode also supports roaming capabilities for mobile users. Roaming means that you can move your wireless PC within your network and the access points will pick up the wireless PC's signal, providing that they both share the same channel and SSID.Before enabling you consider roaming, choose a feasible radio channel and optimum access point position. Proper access point positioning combined with a clear radio signal will greatly enhance performance.infrastructure: a wireless network that is bridged to a wired network via an access point.ad-hoc: a group of wireless devices communicating directly with each other (peer-to-peer) without the use of an access point.roaming: the ability to take a wireless device from one access point's range to another without losing the connection.ssid: your wireless network's name.topology: the physical layout of a network.access point: a device that allows wireless-equipped computers and other devices to communicate with a wired network

32Appendix A: TroubleshootingFrequently Asked QuestionsWireless-G Notebook Adapter with RangeBoosterWhat is ad-hoc mode?When a wireless network is set to ad-hoc mode, the wireless-equipped computers are configured to communicate directly with each other. This type of network will not communicate with any wired network. What is infrastructure mode?When a wireless network is set to infrastructure mode, the wireless network is configured to communicate with a wired network through a wireless access point.What is roaming?Roaming is the ability of a portable computer user to communicate continuously while moving freely throughout an area greater than that covered by 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 node’s 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 point, it then re-registers, and the communication process continues.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
33Appendix A: TroubleshootingFrequently Asked QuestionsWireless-G Notebook Adapter with RangeBoosterthe 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).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. What is WEP?WEP is Wired Equivalent Privacy, a data privacy mechanism based on a shared key algorithm, as described in the 802.11 standard. What is WPA?WPA is Wi-Fi Protected Access, a wireless security protocol that can be used in conjunction with a RADIUS server. What is RADIUS?RADIUS is Remote Authentication Dial-In User Service, which uses an authentication server to control network access.

37Appendix C: Wireless SecuritySecurity PrecautionsWireless-G Notebook Adapter with RangeBoosterAppendix C: Wireless SecurityLinksys wants to make wireless networking as safe and easy for you as possible. The current generation of Linksys products provide several network security features, but they require specific action on your part for implementation. So, keep the following in mind whenever you are setting up or using your wireless network.Security PrecautionsThe following is a complete list of security precautions to take (at least steps 1 through 5 should be followed):1. Change the default SSID. 2. Disable SSID Broadcast. 3. Change the default password for the Administrator account. 4. Enable MAC Address Filtering. 5. Change the SSID periodically. 6. Use the highest encryption algorithm possible. Use WPA if it is available. Please note that this may reduce your network performance. 7. Change the WEP encryption keys periodically. Security Threats Facing Wireless Networks Wireless networks are easy to find. Hackers know that in order to join a wireless network, wireless networking products first listen for “beacon messages”. These messages can be easily decrypted and contain much of the network’s information, such as the network’s SSID (Service Set Identifier). Here are the steps you can take:Change the administrator’s password regularly. With every wireless networking device you use, keep in mind that network settings (SSID, WEP keys, etc.) are stored in its firmware. Your network administrator is the only person who can change network settings. If a hacker gets a hold of the administrator’s password, he, too, can change those settings. So, make it harder for a hacker to get that information. Change the administrator’s password regularly.SSID. There are several things to keep in mind about the SSID: Note: Some of these security features are available only through the network router or access point. Refer to the router or access point’s documentation for more information.
38Appendix C: Wireless SecuritySecurity Threats Facing Wireless NetworksWireless-G Notebook Adapter with RangeBooster1. Disable Broadcast 2. Make it unique 3. Change it often Most wireless networking devices will give you the option of broadcasting the SSID. While this option may be more convenient, it allows anyone to log into your wireless network. This includes hackers. So, don’t broadcast the SSID.Wireless networking products come with a default SSID set by the factory. (The Linksys default SSID is “linksys”.) Hackers know these defaults and can check these against your network. Change your SSID to something unique and not something related to your company or the networking products you use.Change your SSID regularly so that any hackers who have gained access to your wireless network will have to start from the beginning in trying to break in.MAC Addresses. Enable MAC Address filtering. MAC Address filtering will allow you to provide access to only those wireless nodes with certain MAC Addresses. This makes it harder for a hacker to access your network with a random MAC Address. WEP Encryption. Wired Equivalent Privacy (WEP) is often looked upon as a cure-all for wireless security concerns. This is overstating WEP’s ability. Again, this can only provide enough security to make a hacker’s job more difficult.There are several ways that WEP can be maximized:1. Use the highest level of encryption possible 2. Use “Shared Key” authentication3. Change your WEP key regularly WPA. Wi-Fi Protected Access (WPA) is the newest and best available standard in Wi-Fi security. Three modes are available: WPA-Personal, WPA Enterprise, and Radius. WPA-Personal gives you a choice of two encryption methods: TKIP (Temporal Key Integrity Protocol), which utilizes a stronger encryption method and incorporates Message Integrity Code (MIC) to provide protection against hackers, and AES (Advanced Encryption System), which utilizes a symmetric 128-Bit block data encryption. WPA Enterprise offers two encryption methods, TKIP and AES, with dynamic encryption keys. RADIUS (Remote Authentication Dial-In User Service) utilizes a RADIUS server for authentication. Important: Always remember that each device in your wireless network MUST use the same encryption method and encryption key or your wireless network will not function properly.
39Appendix C: Wireless SecuritySecurity Threats Facing Wireless NetworksWireless-G Notebook Adapter with RangeBoosterWPA-Personal. If you do not have a RADIUS server, Select the type of algorithm, TKIP or AES, and enter a password in the Passphrase field of 8-63 characters.WPA Enterprise. WPA used in coordination with a RADIUS server. (This should only be used when a RADIUS server is connected to the Router or other device.) WPA Enterprise offers two encryption methods, TKIP and AES, with dynamic encryption keys. RADIUS. WEP used in coordination with a RADIUS server. (This should only be used when a RADIUS server is connected to the Router or other device.) Implementing encryption may have a negative impact on your network’s performance, but if you are transmitting sensitive data over your network, encryption should be used. These security recommendations should help keep your mind at ease while you are enjoying the most flexible and convenient technology Linksys has to offer.
40Appendix D: Windows HelpWireless-G Notebook Adapter with RangeBoosterAppendix D: Windows HelpAll wireless products require Microsoft Windows. Windows is the most used operating system in the world and comes with many features that help make networking easier. These features can be accessed through Windows Help and are described in this appendix.TCP/IPBefore a computer can communicate with an access point or wireless router, TCP/IP must be enabled. TCP/IP is a set of instructions, or protocol, all PCs follow to communicate over a network. This is true for wireless networks as well. Your PCs will not be able to utilize wireless networking without having TCP/IP enabled. Windows Help provides complete instructions on enabling TCP/IP.Shared ResourcesIf you wish to share printers, folder, or files over your network, Windows Help provides complete instructions on utilizing shared resources.Network Neighborhood/My Network PlacesOther PCs on your network will appear under Network Neighborhood or My Network Places (depending upon the version of Windows you're running).
