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 SecureEasySetupTM 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. Chapter 1: Introduction Welcome 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. nat (network address translation): NAT technology translates IP addresses of a local area network to a different IP address for the Internet. lan (local area network): The computers and networking products that make up the network in your home or office. 1 Wireless-G Broadband Router What's in this User Guide?

Chapter 1: Introduction What's in this User Guide? 3 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. ssid (service set identifier): your wireless network's name. 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 wirelessequipped computers is limited by the distance and interference directly between them. infrastructure: a wireless network that is bridged to a wired network via an access point. ad-hoc: a group of wireless devices communicating directly to each other (peer-topeer) without the use of an access point. 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. Chapter 2: Planning Your Wireless Network Network Topology 4 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. Chapter 2: Planning Your Wireless Network Network Layout 5 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.

The 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. Internet 1, 2, 3, 4 Power Chapter 3: Getting to Know the Wireless-G Broadband Router The Back Panel 6 Wireless-G Broadband Router The Front Panel The Router's SecureEasySetup button (the Cisco logo) and LEDs are located on the front panel. Figure 3-2: The Router's 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. Power Green. The Power LED lights up and will stay on while the Router is powered on. When the Router goes through its self-diagnostic mode during every boot-up, this LED will flash. When the diagnostic is complete, the LED will be solidly lit. Green. The DMZ LED indicates when the DMZ function is being used. This LED will remain lit as long as DMZ is enabled. Green. The WLAN LED lights up whenever there is a successful wireless connection. If the LED is flashing, the Router is actively sending or receiving data over the network. Green. These numbered LEDs, corresponding with the numbered ports on the Router's back panel, serve two purposes. If the LED is continuously lit, the Router is successfully connected to a device through that port. A flashing LED indicates network activity over that port. Green. The Internet LED lights up when there is a connection made through the Internet port. 7 NOTE: SecureEasySetup is a feature that makes it easy to set up your wireless network. If you have SecureEasySetup devices, run the Router's Setup Wizard CD-ROM and follow the on-screen instructions to use SecureEasySetup.

(WEP stands for Wired Equivalent Privacy, WPA stands for Wi-Fi Protected Access, which is a security standard stronger than WEP encryption. WPA2 is stronger than WPA. WPA Enterprise is WPA used in coordination with a RADIUS server. RADIUS stands for Remote Authentication Dial-In User Service.) These are briefly discussed here. For detailed instructions on configuring wireless security for the Router, turn to "Appendix B: Wireless Security." WPA Personal. WPA gives you two encryption methods, TKIP and AES, with dynamic encryption keys. Select the type of algorithm, TKIP or AES. Enter a WPA Shared Key of 8-63 characters. Then enter a Group Key Renewal period, which instructs the Router how often it should change the encryption keys. IMPORTANT: If you are using WPA, always remember that each device in your wireless network MUST use the same WPA method and shared key, or else the network will not function properly. Figure 6-17: Wireless Tab - Wireless Security (WPA Personal) WPA Enterprise. This option features WPA used in coordination with a RADIUS server. (This should only be used when a RADIUS server is connected to the Router.) First, select the type of WPA algorithm you want to use, TKIP or AES. Enter the RADIUS server's IP Address and port number, along with a key shared between the Router and the server. Last, enter a Key Renewal Timeout, which instructs the Router how often it should change the encryption keys.

WPA2 gives you two encryption methods, TKIP and AES, with dynamic encryption keys. Select the type of algorithm, AES, or TKIP + AES. Enter a WPA Shared Key of 8-63 characters. Then enter a Group Key Renewal period, which instructs the Router how often it should change the encryption keys. Figure 6-19: Wireless Tab - Wireless Security (WPA2 Personal) WPA2 Enterprise. This option features WPA2 used in coordination with a RADIUS server. (This should only be used when a RADIUS server is connected to the Router.) First, select the type of WPA algorithm you want to use, AES, or TKIP + AES. Enter the RADIUS server's IP Address and port number, along with a key shared between the Router and the server.
