1Chapter 1: IntroductionWelcomeWireless-G Broadband RouterChapter 1: IntroductionWelcomeThank you for choosing the Linksys Wireless-G Broadband Router. The 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 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 Wireless-G Broadband Router, this access can be shared over the four switched ports or via the wireless broadcast at up to 11Mbps for Wireless-B or up to 54Mbps for Wireless-G.Use the WPA standard to secure your wireless network while the whole network is protected through a Stateful Packet Inspection (SPI) firewall and Network Address Translation (NAT) technology. The Router’s SecureEasySetup™ feature makes it a snap to set up WPA when you have other SecureEasySetup devices—notebooks, printers, other peripherals—comprising your network. Run the Setup Wizard and it will guide you through the steps. You can also access the Router’s features 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 Wireless-G Broadband Router bridges wireless networks of both 802.11b and 802.11g standards and wired networks, allowing them to communicate with each other.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 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 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 Wireless-G Broadband Router.lan (local area network): The computers and networking products that make up the network in your home or office.nat (network address translation): NAT technology translates IP addresses of a local area network to a different IP address for the Internet. wpa (wi-fi protected access): a wireless security protocol using TKIP (Temporal Key Integrity Protocol) encryption, which can be used in conjunction with a RADIUS server.spi (stateful packet inspection) firewall: a technology that inspects incoming packets of information before allowing them to enter the network.firewall: Security measures that protect the resources of a local network from intruders.
