1Chapter 1: IntroductionWelcomeWireless-G USB Network Adapter with Wi-Fi FinderChapter 1: IntroductionWelcomeThank you for choosing the Wireless-G USB Network Adapter with Wi-Fi Finder. With this Adapter, your wireless networking experience will be faster and easier than ever.How does the Adapter do this? Like all wireless products, the Adapter allows for greater range and mobility within your wireless network. Connecting to your PC via the USB port means that this Adapter leaves the PC’s slots open for other purposes. This adapter communicates over the 802.11g wireless standard, one of the newest wireless standards, to communicate with your network. It also has a convenient Wi-Fi Finder that enables you to find an available wireless network to connect to with just a click of a button.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 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. Use the instructions in this Guide to help you connect the Adapter, set it up, and configure it for your network. These instructions should be all you need to get the most out of the Adapter. 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.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.

4Chapter 2: Planning your Wireless NetworkNetwork TopologyWireless-G USB Network Adapter with Wi-Fi FinderChapter 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.access point: device that allows wireless-equipped computers and other devices to communicate with a wired network.ad-hoc: a group of wireless devices communicating directly with each other (peer-to-peer) without the use of an access pointinfrastructure: Configuration in which a wireless network is bridged to a wired network via 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
