15Associated: The Card is connected to a wireless network. The numbers following the word “Associated” refer to the MAC address of the wirelessaccess point that the Card is connected to.Scanning: The Card is searching for an available wireless network and willautomatically scan for one. If the Card continues to scan without joining anetwork, this means that there are no available networks in your area, orthere is another problem. Disable Radio/Enable Radio ButtonIt is possible to completely turn off the Card’s wireless transmitter (radio)by pressing the “Disable Radio” button. After pressing the button, it willchange to read “Enable Radio”. To enable the radio again, click the “EnableRadio” button.Power SavingThe power saving mode will turn the card off when it is not in use. We rec-ommend that you leave this option disabled. When enabled, there will be ashort delay to turn the Card on before it can transmit and receive data.This delay can make your Internet connection appear to be slow.ReconnectIf your Card loses the connection to the wireless network for any reason,simply click on the “Reconnect” button to scan for the wireless networkand reconnect to it.wireless networkingwireless networking14Link Status TabChannel DisplayThis displays the current channel that the wireless network is operatingon. In a wireless network using a wireless router or an access point, thewireless router or access point determines the operating channel. In acomputer-to-computer network, the channel is determined by you. Formore information, see the “Operating Mode” section.Tx Rate DisplayThis shows the current rate at which the Card will transmit and receivewireless data. For more information, see the “Transmit Rate” section.Throughput DisplayTransmit: This field shows the wireless transmission throughput in bytes-per-second.Receive: This field shows the wireless receipt throughput in bytes-per-second.Link Quality/Signal Strength DisplaysLink Quality bar: Indicates the quality of the link between the Card andthe wireless network. Signal Strength bar: Indicates the strength of thesignal coming from the wireless network.State DisplayThis field shows you if the Card is connected to a wireless network or if itis searching for a wireless network. There are two states:
17Using ProfilesThe first thing you will notice is the “Profile Name” bar. Using profilesallows you to save configurations for different wireless networks. Forinstance, if you use your Card at your place of work and also at your home, your wireless network settings may be different for each location.Profiles let you store settings for each location and name them for easyidentification. The “default” profile will contain the initial configurationsetting when you install the Card.In Ad-Hoc mode, each wireless device will use the same SSID to create asmall wireless network. For instance, if you want to connect a PDA to a PC, then both must have the same SSID such as “WLAN”. In addition, the wireless channel must also be the same. See “Ad-Hoc Channel”.To Create a New Profile1. Click the “New” button. The current entry will be highlighted. Type anew name such as “Work”. 2. Click the “Apply” button to save the profile name. 3. Any changes you make to the wireless settings will now apply to this profile.wireless networkingwireless networking16Configuration TabThe “Configuration” tab allows you to set different profiles, networknames, network types, and adjust the Transmit Rate.
19name, the Card will search for the closest available wireless network and join it. If you know the specific network name, you can type it into the “Network Name” field to join that network.To Enter a New Network Name1. Click inside of the “Network Name” box.2. Enter the name of the wireless network you wish to join. Note: Type “ANY” to join the closest wireless network.3. Click the “Apply” button to save the changes.Operating ModeThere are two modes of wireless networking that exist. The first and mostcommon mode is called “Access Point” or “Infrastructure”. The secondmode is called “Peer-to-Peer” or “Ad-Hoc”.Access Point Network ModeUse this mode when you are connecting to a wireless network that uses anaccess point or wireless router.Peer-to-Peer ModeUse this mode when connecting directly to other wireless computers in anetwork that uses no access point or wireless router.wireless networkingwireless networking18To Select a Profile1. Click the down-facing arrow next to the “Profile Name” bar. A drop-downlist of profiles will appear (see below). Note: If you have not saved anyprofiles, only the “Default” profile will appear as a selection.2. Select the profile you want to use by clicking on it.3. Click “Apply” to save the change.The settings for the profile you selected will now be in use.To Delete a Profile1. Select the profile you wish to delete.2. Click the “Delete” button.3. Click “Apply”.The profile is now deleted.To Restore the Default (Factory) SettingsClick the “Defaults” button to restore the factory settings.Network Name BoxThe “Network Name” display lets you specify the name of the wireless network that you want to join. The default factory setting for the “Network Name” is “ANY”. When “ANY” is entered into the network
212. Type in the name of the network into the “Network Name” box. Note:“ANY” does not work in Peer-to-Peer mode. The Network Name canbe anything you want it to be (for instance, “Home”).3. Select an operating channel by clicking on the up/down arrows next to“Peer-to-Peer Channel”. Note: All computers must be on the same channel.4. Click “Apply” to save the changes.Transmit RateThe 802.11b wireless Ethernet standard was engineered so it can operateat different data rates depending on the environment that it is working in.The maximum data rate is 11Mbps (11 megabits-per-second or 11 millionbits-per-second). Under the best of circumstances, the data will be transferred at the highest rate. When excessive noise or other radio signals enter the air, or the wireless device is far enough away from theaccess point that the signal is weak, the chances that wireless data can be corrupted with data errors grows. Data errors result in a slow transfer of data (or connection) because the data has to be resent over and overuntil there are no errors. To combat this, in “Fully Automatic” mode, thedata rate will automatically be rolled back to a slower rate to eliminateerrors by giving the signal more time to reach its intended destination.The result is the fastest transmission possible. There are four possible data rates: 11Mbps, 5.5Mbps, 2Mbps, and 1Mbps. We recommend that you leave the Transmit Rate at “Fully Automatic” and let the Card do the job of transmitting the data at the fastest possible rate. If you set theTransmit Rate at a fixed setting, this will force data to be sent at thatrate, but errors may occur causing the data to be resent. This could actually make the connection SLOWER.wireless networkingwireless networking20To Join an Access Point Wireless NetworkIf you want to join a wireless network that uses an access point or a wireless router: 1. Select “Access Point” in the “Operating Mode” box by clicking the down-facing arrow and highlighting your selection.2. Type in the name of the network into the “Network Name” box or type “ANY” to join the closest wireless network. This is the default factory setting.3. Click “Apply” to save the changes.To Join or Create a Peer-to-Peer Wireless NetworkIf you want to join or create a computer-to-computer network, the“Network Name” and the “Peer-to-Peer Channel” boxes for each computermust be the same. Each computer must be configured to Peer-to-Peer operating mode.1. On each computer, select “Peer-to-Peer” in the “Operating Mode” box byclicking the down-facing arrow and highlighting your selection.
23wireless networkingwireless networking22EncryptionFor security, the 802.11b standard incorporates a method of “scrambling”the data being sent over the air. This is called WEP (Wired EquivalentPrivacy). There are two different levels of WEP: 64-bit encryption and 128-bit encryption. 64-bit encryption is powerful and secure; 128-bitencryption is very powerful and very secure. The reason that two levels, or rates, of encryption exist is because encryption will slow the data speed down. The higher the rate of encryption, the slower the data will be transmitted. 64-bit encryption will reduce data rates nearly 30–40 percent where 128-bit encryption will reduce data rates around 50–60 percent. The trade-off is higher security for slower performance. Keep inmind, however, only large file transfers or continuous streaming data aremost affected by this. Normal browsing of the Internet, downloading files,and sending and retrieving e-mails is not affected.How to Use EncryptionEncryption is fairly easy to understand. Encryption uses what are called“keys” to encode and decode, or “scramble” and “unscramble”, data. Keys can be made by entering a passphrase (password) or can be enteredmanually into the system using an alphanumeric series or a series of two-digit numbers (called “hexadecimal”). In Infrastructure mode, wherean access point or wireless router is being used, the access point or wireless router is programmed with an encryption key. For a wireless device to join the wireless network, the same encryption key must be programmed into the device. Your Card can be programmed with a key in either the passphrase (easy) manner or with alphanumeric or hexadecimal (advanced) entries.To Create an Encryption Key Using a Passphrase—EASY FOR NOVICE USERS1. Click the “Encryption” tab.2. Select the rate of encryption you need to use from the drop-down menu.3. Select “Create Keys with Passphrase”.4. Type the network passphrase you need to use into the “Passphrase” box(for instance, “Passphrase”).5. Click “Apply” to save the passphrase.
25Site Monitor TabYou can use the Site Monitor to view all available wireless networks withinrange of your computer. When you click on the “Site Monitor” tab, you willsee a window showing you basic information about the wireless networksin your area.Network Name: displays the name of the wireless network.Signal: indicates the strength of the signal expressed in dBm.Link Quality: displays the link quality (Excellent, Fair, Poor, NotConnected).Channel: displays the operating channel of the wireless network.Network Address: displays the MAC address of the wireless network’s access point.Clicking on the “Scan” button will rescan the area for wireless networks.To join a wireless network that you see in the Site Monitor, double-click on the name of the network that you want to join.wireless networkingwireless networking24To Create an Encryption Key Manually—FOR ADVANCED USERS ONLY1. Click the “Encryption” tab.2. Select the rate of encryption you need to use from the drop-down menu.3. Select “Create Keys Manually”.4. There are two methods of entering the key, alphanumeric or hexadecimal.If you want to enter an alphanumeric key, select “Alphanumeric:”; select“Hexadecimal:” to enter a hexadecimal key.5. Depending on the rate of encryption you are using, follow the steps below:a. 64-bit: If you selected 64-bit encryption, then enter a 5-characteralphanumeric key or a 10-digit hexadecimal key into “Key 1”. b. 128-bit: If you selected 128-bit encryption, then enter a 13-characteralphanumeric key or a 26-digit hexadecimal key into “Key 1”.Note: In many cases, this key should be provided to you by the network administrator.6. Repeat these steps for keys 2–4 if needed.7. Click “Apply” to save the key(s).
27wireless networkingwireless networking26Wireless Networking Using 802.11bTo form a wireless network, two basic components are used. The first is awireless adapter for a PC. This can be either a USB wireless adapter or aPCMCIA adapter. The adapter gives the PC wireless Ethernet capabilities.The second is a wireless access point, which can connect to a wired LANand allow the wireless PCs to be able to access the wired LAN. A wirelessaccess point can be a stand-alone component or it can be embedded intoa cable/DSL router, thus forming a wireless gateway router. The use ofeach of these types of products is outlined later in this article.Wireless networking is very similar to wired networking, except for a few basic concepts that one must grasp. There are two different ways to network computers using 802.11b. The first, and least used method isthe “Ad-Hoc” method, also known as “Peer-to-Peer”. The more commonlyused method is called “Infrastructure” mode.Peer-to-Peer (Ad-Hoc) NetworkAd-Hoc, or Peer-to-Peer, refers to a wireless configuration in which eachcomputer communicates directly with another. An Ad-Hoc wireless network(LAN) consists of a group of computers, each equipped with a wirelessadapter, connected directly via radio signals to form an independent wireless LAN. Computers in a specific Ad-Hoc wireless LAN must be configured to the same radio channel and network name to communicatewith one another. More than one Ad-Hoc network can exist in the samespace if it is configured to operate on a different channel. There are avarying number of channels depending on which part of the world you areoperating in. The US has 11 channels, Europe has 13 channels, and Japanhas 14 channels. The following diagram shows a typical Ad-Hoc wirelessLAN configuration.Infrastructure Network (Access Point)The use of a wireless access point to connect a wireless LAN to a wiredLAN is called Infrastructure mode. A wireless access point serves as abridge between the wired and wireless network. Connecting the accesspoint to any port on the wired network will give wireless access to allwireless-equipped computers within its coverage area. An access point is configured with a “Service Set Identifier (SSID)”, a “name” given to the wireless network and used by the wireless-equipped computers toaccess the wireless network. Access points can also be configured to useencryption or they can grant access to computers with specific MACaddresses. They effectively double the distance that computers in the wireless LAN can be located from one another. This is because the unitserves as a central point for routing of all the wireless network trafficbetween the wireless-equipped computers. Wireless-equipped computersnetworked together in Infrastructure mode form a group called a “BasicService Set (BSS)”. Up to 64 individual computers can exist at a singletime in a BSS. This is due to the ability of the wireless access point tohandle no more than 64 clients. The diagram below illustrates how thewireless access point works to increase the covered area range of yourwireless network.PC with Wireless DesktopPCI Network AdapterNotebook with WirelessNotebook Network Card PC with Wireless DesktopPCI Network AdapterNotebook with WirelessNotebook Network CardBasic ServiceSet (BSS)WAPNotebook with WirelessNotebook Network CardNotebook with WirelessNotebook Network Card
wireless networking28 29wireless networkingESSBSS2BSS1The diagram below illustrates how a wireless access point acts as a bridgebetween the wireless BSS and the wired network.RoamingMore than one wireless access point can be used to increase the wirelesscoverage in a wireless LAN. The diagram below shows two wireless accesspoints configured to extend coverage beyond that of a single unit. Theoverlapping area of each BSS is called an “Extended Service Set (ESS)”.When a wireless computer enters the ESS, the computer evaluates the signal strength and link quality, then chooses the wireless access pointwith the best-quality signal and link. This activity is known as “roaming”.To configure your wireless access points to allow roaming inside of thewireless network, each unit will be assigned the same Service Set Identifier(SSID). Strategically placing multiple units around an office or inside ofthe home can extend the wireless coverage to the entire premise. The illustration below shows two Basic Service Sets overlapping to form anExtended Service Set.Basic ServiceSet (BSS)WirelessAccess PointDesktop PCDesktop PCSwitchWirelessAccess PointDesktop PCDesktop PCSwitchWirelessAccess Point

wireless networking32Glossary of Wireless Networking TermsDHCP: Dynamic Host Configuration Protocol. This protocol automaticallyconfigures the TCP/IP settings of every computer on your home network.DNS Server Address: DNS stands for Domain Name System, which allowsInternet host computers to have a domain name (such as belkin.com) andone or more IP addresses (such as 192.34.45.8). A DNS server keeps adatabase of host computers and their respective domain names and IPaddresses, so that when a domain name is requested (as in typing“belkin.com” into your Internet browser), the user is sent to the proper IP address. The DNS server address used by the computers on your homenetwork is the location of the DNS server your ISP has assigned. DSL Modem: DSL stands for Digital Subscriber Line. A DSL modem usesyour existing phone lines to transmit data at high speeds. Ethernet: A standard for computer networks. Ethernet networks are connected by special cables and switches, and move data around at up to 100 million bits-per-second [? or, megabits-per-second (Mbps)].IP Address: IP stands for Internet Protocol. An IP address consists of aseries of four numbers, separated by periods, that identifies a single,unique Internet computer host. Example: 192.34.45.8. ISP: Internet Service Provider. An ISP is a business that provides connectivity to the Internet for individuals and other businesses or organizations. ISP Gateway Address: (See ISP for definition.) The ISP Gateway Address isan IP address for the Internet router located at the ISP’s office. Thisaddress is required only when using a cable or DSL modem. LAN: Local Area Network. A LAN is a group of computers and devices connected together in a relatively small area (such as a house or anoffice). Your home network is considered a LAN. MAC Address: MAC stands for Media Access Control. A MAC address is thehardware address of a device connected to a network. A MAC address isunique (different) for every device.NAT: Network Address Translation. This process allows all of the computerson your home network to use one IP address. Using the NAT capability ofthe Belkin 4-Port Cable/DSL Gateway Router, you can access the Internetfrom any computer on your home network without having to purchasemore IP addresses from your ISP. 33PPPoE: Point-to-Point Protocol over Ethernet. Point-to-Point Protocol is a method of secure data transmission originally created for dial-up connections; PPPoE is for Ethernet connections. SPI: Stateful Packet Inspection. SPI is the type of corporate-grade Internet security provided by your Belkin 4-Port Cable/DSL Gateway Router. Using SPI, the gateway acts as a “firewall,” protecting your network from computer hackers. Subnet Mask: A subnet mask, which may be a part of the TCP/IP information provided by your ISP, is a set of four numbers configured like an IP address. It is used to create IP address numbers used only within a particular network (as opposed to valid IP address numbers recognized by the Internet, which must be assigned by InterNIC).
