1Chapter 1: IntroductionWelcomeCompact Wireless-G Broadband RouterChapter 1: IntroductionWelcomeThank you for choosing the Linksys Compact Wireless-G Broadband Router. The Compact Wireless-G Broadband Router will allow you to network wirelessly better than ever, sharing Internet access, files and fun, easily and securely.How does the Compact Wireless-G Broadband Router do all of this? A router is a device that allows access to an Internet connection over a network. With the Compact Wireless-G Broadband Router, this access can be shared over the four switched ports or via the wireless broadcast at either up to 11Mbps for Wireless-B or up to 54Mbps for Wireless-G. In addition, the whole network is protected by NAT technology. For wireless networking, you also have a choice of wireless security methods. Additional security features, as well as configuration options, are accessible 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 LAN, or 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. This is sometimes called a WLAN, or Wireless Local Area Network. The Compact Wireless-G Broadband Router bridges wireless networks of 802.11b, and 802.11g standards and wired networks, allowing them to communicate with each other.With your wired and wireless networks connected to each other and the Internet, you can now share files and Internet access—and even play games. All the while, the Compact Wireless-G Broadband Router protects your networks from unauthorized and unwelcome users.Linksys recommends using the Setup CD-ROM for first-time installation of 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 Compact Wireless-G Broadband Router, 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 Compact Wireless-G Broadband Router.ethernet: an IEEE standard network protocol that specifies how data is placed on and retrieved from a common transmission medium.lan (local area network): the computers and networking products that make up the network in your home or office.802.11b: an IEEE wireless networking standard that specifies a maximum data transfer rate of 11Mbps and an operating frequency of 2.4GHz.802.11g: 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.nat (network address translation): NAT technology translated IP addresses of a local area network to a different IP address for the Internet.

4Chapter 2: Planning Your Wireless NetworkNetwork TopologyCompact Wireless-G Broadband RouterChapter 2: Planning Your Wireless NetworkNetwork TopologyA wireless local area network (WLAN) is exactly like a regular local area network (LAN), except that each computer in the WLAN uses a wireless device to connect to the network. Computers in a WLAN 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 WLAN and wired LAN 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, such as the Compact Wireless-G Broadband Router, 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 Compact Wireless-G Broadband Router has been specifically designed for use with 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. Also used to expand the range of a wireless network.adapter: a device that adds network functionality to your PC.ethernet: IEEE standard network protocol that specifies how data is placed on and retrieved from a common transmission medium.network: a series of computers or devices connected for the purpose of data sharing, storage, and/or transmission between users.
