1Chapter 1: IntroductionWelcomeWireless-G Broadband Router with SpeedBoosterChapter 1: IntroductionWelcomeThank you for choosing the Linksys Wireless-G Broadband Router with SpeedBooster. The Wireless-G Broadband Router with SpeedBooster will allow you to network wirelessly better than ever, sharing Internet access, files and fun, easily and securely.How does the Wireless-G Broadband Router with SpeedBooster do all of this? A router is a device that allows access to an Internet connection over a network. With the Wireless-G Broadband Router with SpeedBooster, this access can be shared over the four switched ports or via the wireless network, broadcast at either 11Mbps for Wireless-B or 54Mbps for Wireless-G. In addition, WEP encryption provides greater security opportunities while the whole network is protected through a Stateful Packet Inspection (SPI) firewall and NAT technology. All of these security features, as well as full configurability, are accessed through the easy-to-use browser-based utility.But what does all of this mean? Networks are useful tools for sharing computer resources. You can access one printer from different computers and access data located on another computer's hard drive. Networks are even used for playing multiplayer video games. So, networks are not only useful in homes and offices, they can also be fun.PCs on a wired network create a Local Area Network. They are connected with Ethernet cables, which is why the network is called “wired”. PCs equipped with wireless cards or adapters can communicate without cumbersome cables. By sharing the same wireless settings, within their transmission radius, they form a wireless network. The Wireless-G Broadband Router with SpeedBooster bridges wireless networks of both 802.11b and 802.11g standards and wired networks, allowing them to communicate with each other. And since this Router has SpeedBooster technology, your wireless network performance increases by up to 30% from old 802.11g standards. In fact, even non-SpeedBooster-equipped devices on your network will see a speed improvement when communicating with SpeedBooster-enhanced equipment!With your networks all connected, wired, wireless, and the Internet, you can now share files and Internet access—and even play games. All the while, the Wireless-G Broadband Router with SpeedBooster protects your networks from unauthorized and unwelcome users.You should always use the Setup CD-ROM when you first install the Router. If you do not wish to run the Setup Wizard on the Setup CD-ROM, then use the instructions in this Guide to help you connect the Wireless-G Broadband Router with SpeedBooster, set it up, and configure it to bridge your different networks. These instructions should be all you need to get the most out of the Wireless-G Broadband Router with SpeedBooster. lan (Local Area Network): The computers and networking products that make up the network in your home or office802.11b: an IEEE wireless networking standard that specifies a maximum data transfer rate of 11Mbps and an operating frequency of 2.4GHz. 802.11b: an IEEE wireless networking standard that specifies a maximum data transfer rate of 54Mbps, an operating frequency of 2.4GHz, and backward compatibility with 802.11b devices. browser: an application program that provides a way to look at and interact with all the information on the World Wide Web.mbps: one million bits per second; a unit of measurement for data transmission

4Chapter 2: Planning Your Wireless NetworkNetwork TopologyWireless-G Broadband Router with SpeedBoosterChapter 2: Planning Your Wireless NetworkNetwork TopologyA wireless local area network is exactly like a regular local area network (LAN), except that each computer in the wireless network uses a wireless device to connect to the network. Computers in a wireless network share the same frequency channel and SSID, which is an identification name shared by the wireless devices belonging to the same wireless network.Ad-Hoc versus Infrastructure ModeUnlike wired networks, wireless networks have two different modes in which they may be set up: infrastructure and ad-hoc. An infrastructure configuration is a wireless and wired network communicating to each other through an access point. An ad-hoc configuration is wireless-equipped computers communicating directly with each other. Choosing between these two modes depends on whether or not the wireless network needs to share data or peripherals with a wired network or not. If the computers on the wireless network need to be accessible by a wired network or need to share a peripheral, such as a printer, with the wired network computers, the wireless network should be set up in Infrastructure mode. The basis of Infrastructure mode centers around a wireless router or an access point, which serves as the main point of communications in a wireless network. The Router transmits data to PCs equipped with wireless network adapters, which can roam within a certain radial range of the Router. You can arrange the Router and multiple access points to work in succession to extend the roaming range, and you can set up your wireless network to communicate with your Ethernet hardware as well. If the wireless network is relatively small and needs to share resources only with the other computers on the wireless network, then the Ad-Hoc mode can be used. Ad-Hoc mode allows computers equipped with wireless transmitters and receivers to communicate directly with each other, eliminating the need for a wireless router or access point. The drawback of this mode is that in Ad-Hoc mode, wireless-equipped computers are not able to communicate with computers on a wired network. And, of course, communication between the wireless-equipped computers is limited by the distance and interference directly between them. Network LayoutThe Wireless-G Broadband Router has been specifically designed for use with both your 802.11b and 802.11g products. Now, products using these standards can communicate with each other. Infrastructure: a wireless network that is bridged to a wired network via an access point.ssid: your wireless network’s name.ad-hoc: a group of wireless devices communicating directly to each other (peer-to-peer) without the use of an access point.access point: a device that allows wireless-equipped computers and other devices to communicate with a wired network.

8Chapter 4: Connecting the Wireless-G Broadband RouterOverviewWireless-G Broadband Router with SpeedBoosterChapter 4: Connecting the Wireless-G Broadband RouterOverviewThis chapter includes two sets of instructions. If the Wireless-G Broadband Router will be the only router in your network, follow the instructions in “Hardware Installation for Connection to Your Broadband Modem.” You may wish to run some applications, such as Parental Control, for only certain PCs on your network and will need to run the Wireless-G Broadband Router behind another router to do this. If you want to install the Wireless-G Broadband Router behind another router in your network, follow the instructions in “Connecting One Router to Another.”Hardware Installation for Connection to Your Broadband Modem1. Power down your network devices.2. Locate an optimum location for the Router. The best place for the Router is usually at the center of your wireless network, with line of sight to all of your mobile stations.3. Fix the direction of the antennas. Try to place the Router in a position that will best cover your wireless network. Normally, the higher you place the antenna, the better the performance will be.4. Connect a standard Ethernet network cable to the Router’s Internet port. Then, connect the other end of the Ethernet cable to your cable or DSL broadband modem.Figure 4-1: Connecting Your Modemdsl: an always-on broadband connection over traditional phone lineshardware: the physical aspect of computers, telecommunications, and other information technology devices

10Chapter 4: Connecting the Wireless-G Broadband RouterConnecting One Router to AnotherWireless-G Broadband Router with SpeedBoosterConnecting One Router to AnotherSome applications, such as Parental Control, apply setting to all PCs connected to the Router. Sometimes, you may not want those settings to apply to all settings in your network. When this is the case, you may want to connect the Router behind another, so you can have some PCs connected to the Router with Parental Control and some connected to a Router without.Before you connect one Router to another, you must make sure that both have different IP Addresses. This is mandatory because both routers may be set to the same IP address by default, right out of the box. If both routers have the same IP address, then you may not be able to set up the Router with Parental Control.First, make sure the Router is NOT connected to your network. Then follow these instructions:1. To access the other router’s Web-based Utility, launch Internet Explorer or Netscape Navigator, and enter the other router’s default IP address, 192.168.1.1, or whatever IP Address you have set it to, in the Address field. Then, press Enter.2. A password request page will appear. Leave the User Name field blank. In the Password field, enter the password you have set (the default password is admin). Then click the OK button.3. The first screen that appears will display the Setup tab. In the Network Setup section, there is a setting called Local IP Address, which is set to 192.168.1.1. Change this to 192.168.2.1.4. Click the Save Settings button to save your change, and then exit the Web-based Utility.5. Power down your network devices. Now you will begin the hardware installation of Broadband Router.6. Locate an optimum location for the Broadband Router. The best place for the Broadband Router is usually at the center of your wireless network, with line of sight to all of your mobile stations.7. Fix the direction of the antennas. Try to place the Router in a position that will best cover your wireless network. Normally, the higher you place the antenna, the better the performance will be.Figure 4-5: Diagram for Connection to Another RouterNOTE: Steps 1-4 are instructions for a typical Linksys router; however, if you are using a non-Linksys router, refer to the other router’s documentation for instructions on how to change its local IP address to 192.168.2.1.InternetBroadbandModemRouterWireless-G Broadband RouterMultiple PCsInternet BroadbandModemRouter Wireless-G Broadband RouterFigure 4-4: Connecting the Router Behind Another
