1Chapter 1: IntroductionWelcomeWireless-G Broadband Router with RangeBoosterChapter 1: IntroductionWelcomeThank you for choosing the Linksys Wireless-G Broadband Router with RangeBooster. The Wireless-G Broadband Router with RangeBooster will allow you to network wirelessly better than ever, sharing Internet access, files and fun, easily and securely and with a greater range of up to twice as far as standard Wireless-G.How does the Wireless-G Broadband Router with RangeBooster 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 with RangeBooster, 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. 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 with RangeBooster bridges wireless networks of both 802.11b and 802.11g standards and wired networks, allowing them to communicate with each other.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 with RangeBooster, 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 with RangeBooster.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.

4Chapter 2: Planning Your Wireless NetworkNetwork TopologyWireless-G Broadband Router with RangeBoosterChapter 2: Planning Your Wireless NetworkNetwork TopologyA 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 ModeUnlike 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 with RangeBooster, 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 LayoutThe Wireless-G Broadband Router with RangeBooster 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.

19Chapter 6: Configuring the Wireless-G Broadband Router with RangeBoosterThe Wireless Tab - Wireless SecurityWireless-G Broadband Router with RangeBoosterThe Wireless Tab - Wireless SecurityThe Wireless Security settings configure the security of your wireless network. There are four wireless security mode options supported by the Router: WEP, WPA Personal, PSK2, PSK2-Mixed, WPA-Enterprise, PSK2 + RADIUS, and RADIUS. (WEP stands for Wired Equivalent Privacy, and WPA stands for Wi-Fi Protected Access. WPA is a stronger security method than WEP. PSK2 stands for Pre-shared Key 2, and is stronger than WPA-Personal. RADIUS stands for Remote Authentication Dial-In User Service.) These seven are briefly discussed here.WEP. WEP is a basic encryption method, which is not as secure as WPA Personal. To use WEP, select a level of WEP encryption, 40/64 bits (10 hex digits) or 104/128 bits (26 hex digits). Then either generate a WEP key using the Passphrase or enter the WEP key manually and select a TX (Transmit) Key (choose which Key to use).WPA-Personal. WPA gives you two encryption methods, TKIP and AES, with dynamic encryption keys. Select the type of encryption, TKIP or AES. Enter a passphrase (pre-shared key) of 8-63 characters. Then enter a Key Renewal period, which instructs the Router how often it should change the encryption keys.Figure 5-20: Wireless Tab - Wireless Security (WEP)Figure 5-21: Wireless Tab - Wireless Security (WPA-Personal)IMPORTANT: If you are using WPA Personal, always remember that each device in your wireless network MUST use the same WPA Personal method and passphrase, or else the network will not function properly.IMPORTANT: If you are using WEP encryption, always remember that each device in your wireless network MUST use the same WEP encryption method and encryption key, or else your wireless network will not function properly.

23Chapter 6: Configuring the Wireless-G Broadband Router with RangeBoosterThe Wireless Tab - Advanced Wireless SettingsWireless-G Broadband Router with RangeBoosterThe Wireless Tab - Advanced Wireless SettingsThis tab is used to set up the Router’s advanced wireless functions. These settings should only be adjusted by an expert administrator as incorrect settings can reduce wireless performance.Advanced WirelessFrame Burst Mode. Enabling this option should provide your network with greater performance, depending on the manufacturer of your wireless products. The default setting is Enabled.AP Isolation. This isolates all wireless clients and wireless devices on your network from each other. Wireless devices will be able to communicate with the Router but not with each other. To use this function, click Enabled. AP Isolation is disabled by default.Authentication Type. The default is set to Auto, which allows either Open System or Shared Key authentication to be used. With Open System authentication, the sender and the recipient do NOT use a WEP key for authentication. With Shared Key authentication, the sender and recipient use a WEP key for authentication.Basic Rate. The Basic Rate setting is not actually one rate of transmission but a series of rates at which the Router can transmit. The Router will advertise its Basic Rate to the other wireless devices in your network, so they know which rates will be used. The Router will also advertise that it will automatically select the best rate for transmission. The default setting is Default, when the Router can transmit at all standard wireless rates (1-2Mbps, 5.5Mbps, 11Mbps, 18Mbps, and 24Mbps). Other options are 1-2Mbps, for use with older wireless technology, and All, when the Router can transmit at all wireless rates. The Basic Rate is not the actual rate of data transmission. If you want to specify the Router’s rate of data transmission, configure the Transmission Rate setting.Transmission Rate. The rate of data transmission should be set depending on the speed of your wireless network. You can select from a range of transmission speeds, or you can select Auto to have the Router automatically use the fastest possible data rate and enable the Auto-Fallback feature. Auto-Fallback will negotiate the best possible connection speed between the Router and a wireless client. The default setting is Auto.Transmission Power. The greater the transmission power used, the larger the area a wireless network covers. To minimize the likelihood of eavesdropping by unauthorized wireless users, do not use more transmission power than necessary to cover the range needed by your wireless network. Try using the Router at different levels of transmission power, and determine how much power is needed to reach the wireless client, such as a PC or access point, that is farthest from the Router. Then select the appropriate level, Full, Half, Quarter, Eighth, or Min, from the drop-down menu. The default setting is Full.Figure 5-29: Wireless Tab - Advanced Wireless Settings
24Chapter 6: Configuring the Wireless-G Broadband Router with RangeBoosterThe Wireless Tab - Advanced Wireless SettingsWireless-G Broadband Router with RangeBoosterCTS Protection Mode. CTS (Clear-To-Send) Protection Mode’s default setting is Auto. The Router will automatically use CTS Protection Mode when your Wireless-G products are experiencing severe problems and are not able to transmit to the Router in an environment with heavy 802.11b traffic. This function boosts the Router’s ability to catch all Wireless-G transmissions but will severely decrease performance.Beacon Interval. The Beacon Interval value indicates the frequency interval of the beacon. A beacon is a packet broadcast by the Router to synchronize the wireless network. The default value is 100. DTIM Interval. This value indicates the interval of the Delivery Traffic Indication Message (DTIM). A DTIM field is a countdown field informing clients of the next window for listening to broadcast and multicast messages. When the Router has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval value. Its clients hear the beacons and awaken to receive the broadcast and multicast messages. The default value is 1.Fragmentation Threshold. This value specifies the maximum size for a packet before data is fragmented into multiple packets. If you experience a high packet error rate, you may slightly increase the Fragmentation Threshold. Setting the Fragmentation Threshold too low may result in poor network performance. Only minor reduction of the default value is recommended. The default value is 2346.RTS Threshold. Should you encounter inconsistent data flow, only minor reduction of the default value, 2346, is recommended. If a network packet is smaller than the preset RTS threshold size, the RTS/CTS mechanism will not be enabled. The Router sends Request to Send (RTS) frames to a particular receiving station and negotiates the sending of a data frame. After receiving an RTS, the wireless station responds with a Clear to Send (CTS) frame to acknowledge the right to begin transmission. The default value is 2346.Change these settings as described here and click the Save Settings button to apply your changes or Cancel Changes to cancel your changes.
