1Chapter 1: IntroductionWelcomeWireless-G Router for Mobile BroadbandChapter 1: IntroductionWelcomeThank you for choosing the Linksys Wireless-G Router for Mobile Broadband The Wireless-G Router for Mobile Broadband will allow you to network wirelessly better than ever, sharing Internet access, files and fun, easily and securely.How does the Wireless-G Router for Mobile Broadband do all of this? A router is a device that allows access to an Internet connection over a network. With the Wireless-G Router for Mobile Broadband, you can access the Internet through either your mobile broadband service (requires a mobile broadband data card, available separately), or you can use a cable or DSL modem for broadband service. Plus, this access can be shared over the four switched ports or via the wireless broadcast at up to 54Mbps for Wireless-G or up to 11Mbps for Wireless-B.Use the WPA or WPA2 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. 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 Router for Mobile Broadband 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 Router for Mobile Broadband protects your networks from unauthorized and unwelcome users.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.wpa2 (wi-fi protected access2: a wireless security protocol using TKIP (Temporal Key Integrity Protocol) encryption and AES (Advanced Encryption System) with dynamic encryption keys, which can be used in conjunction with a RADIUS server.

4Chapter 2: Planning Your Wireless NetworkNetwork TopologyWireless-G Router for Mobile BroadbandChapter 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 Router for Mobile Broadband, 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 Router for Mobile Broadband has been specifically designed for use with both your 802.11b and 802.11g products. It is compatible with all 802.11g and 802.11b adapters, such as the notebook adapters for your 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.
5Chapter 2: Planning Your Wireless NetworkNetwork LayoutWireless-G Router for Mobile Broadbandlaptop computers, PCI adapters for your desktop PCs, and USB adapters when you want to enjoy USB connectivity. The Router will also communicate with the Wireless PrintServer and Wireless Ethernet Bridges.When you wish to connect your wireless network with your wired network, you can use the Wireless-G Router for Mobile Broadband’s four Ethernet LAN ports.

68Chapter 8: Configuring the Wireless-G Router for Mobile BroadbandThe Wireless Tab - Advanced Wireless SettingsWireless-G Router for Mobile BroadbandThe 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 WirelessAuthentication 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 value is Auto.CTS Protection Mode. CTS (Clear-To-Send) Protection Mode should remain disabled unless you are having severe problems with your Wireless-G products not being 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.Frame Burst. Enabling this option should provide your network with greater performance, depending on the manufacturer of your wireless products. If you are not sure how to use this option, keep the default, Disable.Beacon Interval. The default value is 100. Enter a value between 1 and 65,535 milliseconds. 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.DTIM Interval. This value, between 1 and 255, 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 Figure 8-29: Wireless Tab - Advanced Wireless Settings
69Chapter 8: Configuring the Wireless-G Router for Mobile BroadbandThe Wireless Tab - Advanced Wireless SettingsWireless-G Router for Mobile Broadbandsends 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. In most cases, it should remain at its default value of 2346.RTS Threshold. Should you encounter inconsistent data flow, only minor reduction of the default value, 2347, 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 RTS Threshold value should remain at its default value of 2347. 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, select On. AP Isolation is Off by default.Change these settings as described here, and click the Save Settings button to apply your changes or Cancel Changes to cancel your changes.
