Think of the Linksys Wireless-B Broadband Router as a kind of "splitter" for your Internet connection. Just connect your DSL or Cable Modem to the Router, and all the computers in your household can share the Internet -- all at the same time. You can connect your home computers directly to the Router with Ethernet cables, or put wireless network adapters in them and communicate over radio waves, saving the trouble and expense of running cables through your house. Once your computers are connected to the Router, they can communicate with each other too, sharing resources and files. All your computers can print on a shared printer connected anywhere in the house. And your computers can share all kinds of files -- music, digital pictures, and documents. Keep all your digital music on one computer, and listen to it anywhere in the house. Organize all of your family's digital pictures in one place, to simplify finding the ones you want, and easing backup to CD-R. Play head-to-head computer games within the household, or against Internet opponents. Utilize extra free space on one computer when another's hard drive starts to fill up. Your home network is secure, too. All wireless communications are protected by 128-bit encryption. The Router helps keep intruders out of your computers. It's all easier than you think -- the included Setup Wizard takes you through configuring your network, step by step. With the Linksys Wireless-B Broadband Router at the heart of your home network, you don't need to be a networking genius to share printers, files, and your Internet connection -- with or without wires.

Chapter 1: Introduction What's in this Guide? 3 Wireless-B Broadband Router Chapter 2: Planning your Wireless Network Network Topology A wireless LAN is a group of computers, each equipped with one Linksys wireless adapter. Computers in a wireless LAN must be configured to share the same radio channel. The Linksys wireless adapters provide access to a wired LAN for wireless workstations. An integrated wireless and wired LAN is called an infrastructure configuration. A group of Linksys wireless adapter users and a Wireless-B Broadband Router compose a Basic Service Set (BSS). Each Linksys wireless adapter PC in a BSS can talk to any computer in a wired LAN infrastructure via the Wireless-B Broadband Router. An infrastructure configuration extends the accessibility of a Linksys wireless adapter PC to a wired LAN, and doubles the effective wireless transmission range for two Linksys wireless adapter PCs. Since the Wireless-B Broadband Router is able to forward data within its BSS, the effective transmission range in an infrastructure LAN is doubled. LAN: the computers and networking products that make up your local network Roaming Infrastructure mode also supports roaming capabilities for mobile users. More than one BSS can be configured as an Extended Service Set (ESS). This continuous network allows users to roam freely within an ESS. All PCs equipped with a Linksys wireless adapter within one ESS must be configured with the same ESS ID and use the same radio channel. Before enabling an ESS with roaming capability, choosing a feasible radio channel and optimum Wireless-B Broadband Router position is recommended. Proper router 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. Chapter 2: Planning your Wireless Network Network Topology 4 Wireless-B Broadband Router Network Layout The Wireless-B Broadband Router is compatible with all 802.11b adapters, such as the PC Card (WPC11) for your laptop computers, PCI Card (WMP11) for your desktop PC, and USB Adapter (WUSB11) for when you want to enjoy USB connectivity. The Router will also communicate with the wireless PrintServer (WPS11) and bridges (WET11). When you wish to connect your wired network with your wireless network, the Wireless-B Broadband Router's LAN port can be connected to any of Linksys's switches (such as the EZXS55W or EZXS88W). With these, and many other, Linksys products, your networking options are limitless.
