4 Chapter 2: Planning Your Wireless Network Network Topology Wireless-G Broadband Router Chapter 2: Planning Your Wireless Network Network Topology A 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 Mode Unlike 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 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 Layout The 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 (service set identifier): 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. 5 Chapter 2: Planning Your Wireless Network Network Layout Wireless-G Broadband Router The Wireless-G Broadband Router is compatible with all 802.11b and 802.11g adapters, such as the Notebook Adapters (WPC54G, WPC11) for your laptop computers, PCI Adapter (WMP54G, WMP11) for your desktop PC, and USB Adapter (WUSB54G, WUSB11) when you want to enjoy USB connectivity. The Broadband Router will also communicate with the Wireless PrintServer (WPS54G) and Wireless Ethernet Bridges (WET54G, WET11). When you wish to connect your wireless network with your wired network, you can use the Wireless-G Broadband Router’s four LAN ports. To add more ports, any of the Wireless-G Broadband Router's LAN ports can be connected to any of Linksys's switches (such as the SD205 or SD208). With these, and many other, Linksys products, your networking options are limitless. Go to the Linksys website at www.linksys.com for more information about products that work with the Wireless-G Broadband Router. 6 Chapter 3: Getting to Know the Wireless-G Broadband Router The Back Panel Wireless-G Broadband Router Chapter 3: Getting to Know the Wireless-G Broadband Router The Back Panel The Router's ports, where the cables are connected, are located on the back panel. Reset ButtonThere are two ways to reset the Router's factory defaults. Either press the Reset Button, for approximately five seconds, or restore the defaults from the Administration tab - Factory Defaults in the Router's Web-based Utility. InternetThe Internet port is where you will connect your broadband Internet connection. 1, 2, 3, 4These ports (1, 2, 3, 4) connect the Router to your networked PCs and other Ethernet network devices. PowerThe Power port is where you will connect the power adapter. IMPORTANT:Resetting the Router will erase all of your settings (Internet connection, wireless security, and other settings) and replace them with the factory defaults. Do not reset the Router if you want to retain these settings. Figure 3-1: The Router’s Back Panel 7 Chapter 3: Getting to Know the Wireless-G Broadband Router The Front Panel Wireless-G Broadband Router The Front Panel The Router’s SecureEasySetup button (the Cisco logo) and LEDs are located on the front panel. (Cisco logo)Orange/White. The Cisco logo is the Router’s SecureEasySetup button. It lights up and will stay orange when the Router is powered on. The color orange indicates that the Router is not using the SecureEasySetup feature, while the color white indicates that the Router is using the SecureEasySetup feature. When the Router enters SecureEasySetup mode, the Cisco logo will turn white and start flashing. After the Router has generated the SSID and WPA-PSK (also called WPA-Personal) key, the Cisco logo will stop flashing and stay white. To clear the SSID and WPA-PSK key, press and hold down the Cisco logo for five seconds. The Cisco logo will flash slowly as the Router resets itself. The Cisco logo will turn orange to indicate a successful reset. PowerGreen. The Power LED lights up and will stay on while the Router is powered on.
