1Chapter 1: IntroductionWelcomeWireless-G Notebook AdapterChapter 1: IntroductionWelcomeThank you for choosing the Wireless-G Notebook Adapter. With this Adapter, your wireless networking experience will be faster and easier than ever.Like all wireless products, the Adapter allows for greater range and mobility within your wireless network. This adapter communicates over the 54Mbps 802.11g wireless standard, which is almost five times faster than 802.11b. But since they share the same 2.4GHz radio band, the Adapter can also communicate with the widely used 11Mbps 802.11b standard.PCs equipped with wireless cards and adapters can communicate without cumbersome cables. By sharing the same wireless settings, within their transmission radius, they form a wireless network. The included Setup Wizard will walk you through configuring the adapter to your network's settings, step by step. Then just slide it into your notebook's PC Card slot and enjoy network access with your notebook computer, while retaining true mobility.Once you're connected, you can keep in touch with your e-mail, access the Internet, and share files and other resources such as printers and network storage with other computers on the network. At home, you can surf the web or use instant messaging to chat with friends while sitting out on the patio. Your wireless connection is protected by the new, industrial-strength security of Wireless Protected Access (WPA).You'll also be able to connect with any of the growing number of public wireless hotspots springing up in coffee shops, airport lounges, hotels and convention centers. And as those hotspots upgrade to the new high-speed Wireless-G standard, you'll be ready to take advantage of the increased speeds.Get connected to current-standard 802.11b networks today, and be prepared for the future with the Wireless-G Notebook Adapter from Linksys.802.11b: an IEEE wireless networking standard that specifies a maximum data transfer rate of 11Mbps and an operating frequency of 2.4GHz.adapter: a device that adds network functionality to your PC.network: a series of computers or devices connected for the purpose of data sharing, storage, and/or transmission between users.802.11g an IEEE wireless networking standard that specifies a maximum data transfer rate of 54Mbps and an operating frequency of 2.4GHz.

4Chapter 2: Planning your Wireless NetworkNetwork TopologyWireless-G Notebook AdapterChapter 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.
5Chapter 2: Planning your Wireless NetworkNetwork LayoutWireless-G Notebook AdapterNetwork LayoutLinksys wireless access points and wireless routers have been designed for use with 802.11a, 802.11b, and 802.11g products. With 802.11g products communicating with the 802.11b standard and some products incorporating both “a” and “g”, products using these standards can communicate with each other.Access points and wireless routers are compatible with 802.11a, 802.11b and 802.11g adapters, such at the PC Cards for your laptop computers, PCI Card for your desktop PC, and USB Adapters for when you want to enjoy USB connectivity. Wireless products will also communicate with the wireless PrintServer.When you wish to connect your wired network with your wireless network, network ports on access points and wireless routers can be connected to any of Linksys's switches or routers.With these, and many other, Linksys products, your networking options are limitless.

30Appendix A: TroubleshootingFrequently Asked QuestionsWireless-G Notebook AdapterFrequently Asked QuestionsCan I run an application from a remote computer over the wireless network?This will depend on whether or not the application is designed to be used over a network. Consult the application’s user guide to determine if it supports operation over a network.Can I play computer games with other members of the wireless network?Yes, as long as the game supports multiple players over a LAN (local area network). Refer to the game’s user guide for more information.What is the IEEE 802.11b standard?It is one of the IEEE standards for wireless networks. The 802.11b standard allows wireless networking hardware from different manufacturers to communicate, provided that the hardware complies with the 802.11b standard. The 802.11b standard states a maximum data transfer rate of 11Mbps and an operating frequency of 2.4GHz.What IEEE 802.11b features are supported?The product supports the following IEEE 802.11b functions: • CSMA/CA plus Acknowledge protocol • Multi-Channel Roaming • Automatic Rate Selection • RTS/CTS feature • Fragmentation • Power Management What 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. The ad-hoc wireless 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 fragmentation: breaking a packet into smaller units when transmitting over a network medium that cannot support the original size of the packet. mbps: one million bits per second; a unit of measurement for data transmission.
31Appendix A: TroubleshootingFrequently Asked QuestionsWireless-G Notebook Adaptermaintain 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 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).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. dsss: Frequency transmission with a redundant bit pattern resulting in a lower probability of information being lost in transit.ism band: radio bandwidth utilized in wireless transmissions.spread spectrum: wideband radio frequency technique used for more reliable and secure data transmission.
32Appendix A: TroubleshootingFrequently Asked QuestionsWireless-G Notebook AdapterWould 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 offers the encryption function (WEP) to enhance security and access control.What is WEP?WEP is Wired Equivalent Privacy, a data privacy mechanism based on a shared key algorithm, as described in the IEEE 802.11 standard.
33Appendix B: Wireless SecuritySecurity PrecautionsWireless-G Notebook AdapterAppendix B: 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.
34Appendix B: Wireless SecuritySecurity Threats Facing Wireless NetworksWireless-G Notebook Adapter1. 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: Radius-PSK, WPA Radius, and Radius. Radius-PSK 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 RADIUS 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.
35Appendix B: Wireless SecuritySecurity Threats Facing Wireless NetworksWireless-G Notebook AdapterWPA-PSK. 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 RADIUS. 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 Radius 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.
36Appendix C: Windows HelpWireless-G Notebook AdapterAppendix C: 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). Windows Help provides complete instructions on adding PCs to your network.
