Wireless LAN Access Point User’s Guide6Wireless LAN NetworkingIntroduction to NetworksA network is a group of computers and associated devices that can communicatewith each other through permanent connections, such as cables, or temporaryconnections made through telephone or other communication links. A networkcan be as small as a local area network (LAN) consisting of a few computers,printers, and other devices, or it can consist of many small and large computersdistributed over a vast geographic area as a wide area network (WAN).A network allows you to share files, programs, scanners, printers, fax machines,etc.
Wireless LAN Networking7Wireless LAN NetworksA wireless LAN is a network that uses radio signals to send and receive databetween individual devices. Wireless LANs are often used in office or factorysettings where a user must carry a portable computer from place to place.Wireless LANs are also becoming a popular and convenient way of connectingcomputers in a home environment.Wireless LANs perform the same functions as a wired LAN, but without the wire.The network devices are connected to each other by radio waves. By using theWireless LAN Access Point, the wireless LAN can be connected to a wirednetwork.The Wireless LAN Access Point provides connectivity between wireless clientsand Ethernet (wired) clients. The Access Point complies with the IEEE 802.11standard, enabling communication among all wireless clients that meet thisstandard.
Wireless LAN Access Point User’s Guide8Stand-Alone Wireless NetworkThe stand-alone wireless network is the simplest use of an Access Point. In thisconfiguration, the Access Point acts as a relay between wireless clients. Thisenables the transfer of information among all computers within the Access Pointcoverage area.To communicate with the Access Point and other computers in the network, theAccess Point and all computers in the network must have the same Group ID.While an Access Point is not required, its relay capability effectively doubles thecommunication distance between two computers.Wireless ClientWireless ClientAccess Point
Wireless LAN Networking9Infrastructure NetworkIn an infrastructure network, the Access Point connects clients to a wirednetwork. This enables the wireless clients to access all computers and peripheralson the wired network.Multiple Access Points can be used to achieve seamless wireless accessthroughout an extended service area. All Access Points and wireless clients musthave the same Group ID. Roaming among different Access Points is controlledautomatically to maintain the wireless connection at all times.Wireless ClientAccess PointWired ClientHub or SwitchWireless ClientNetwork Server
Wireless LAN Access Point User’s Guide10TCP/IP AddressingTCP/IP (Transmission Control Protocol/Internet Protocol) has become thestandard for network data transmission. The Wireless LAN Access Point usesTCP/IP addressing to communicate between both wired and wireless clients.If you are installing the Wireless LAN Access Point into a wired LAN, you mustobtain a static IP address and a subnet mask for the Access Point from the wirednetwork administrator. See Configuring the Wireless LAN Settings.If you don’t have a network administrator, you will have to select an IP addressfrom one of the available blocks of addresses.Selecting an IP AddressAn IP address consists of four components. Each component can contain up to256 numbers (0 to 255). Thus, you can select a unique address from a range ofaddresses (0.0.0.0 to 255.255.255.255) to identify a device within a network.Not all addresses are available for private networks. Only the addresses in thefollowing three blocks are available: 10. 0 . 0. 0 — 10.255.255.255172. 16. 0. 0 — 172. 31.255.255192.168. 0. 0 — 192.168.255.255Define your network by determining the number of addresses you will need(allow for expansion).For more information on IPaddresses, see the NetworkWorking Group SpecificationRFC 1918 on the Internet.For correct IP addressinformation for your wirelessLAN installation, contact yournetwork administrator.
Wireless LAN Networking11For example:If your network will consist of 10 wired clients and 10 wireless clients, youcould define the first 3 components of your address as 10.100.100. Next, youwould define the fourth component range. You need 20 (allowing for anexpansion of 10) addresses for your wired clients and 20 (allowing for anexpansion of 10) addresses for your wireless clients.You could then reserve a block of addresses for the wired clients of10.100.100.0 through 10.100.100.19 and another block for wireless clients of10.100.100.20 through 10.100.100.39. Now you can start assigning appropriateaddresses to individual clients.
Wireless LAN Access Point User’s Guide12Creating a Subnet MaskIn addition to an IP address, you will need to define a subnet mask to ensure thatyour computers only communicate with other computers and devices that arewithin your network.A subnet mask has four components that correspond to the four components ofthe IP address. Like the IP address, each component can contain up to 256numbers (0 to 255). These numbers determine if an IP address component mustbe an exact match or if a range of numbers is acceptable.If the subnet mask number for an IP component is 255, that component must bean exact match for communication to take place. If the mask number is 0, anynumber in the component is acceptable. A mask number between 0 and 255determines a range of numbers between the number and 255 that are acceptable.If you use a mask number of 250, IP address numbers between 250 and 255 areacceptable.For example: if you choose an IP address of 10.100.100.1 and a subnet mask of255.255.255.0, the first three components of the IP address must match exactly,and any number from 0 to 255 in the fourth component is acceptable forcommunication to take place.The use of these addresses and masks is limited only by your imagination. Youcan use any rationale you like to select your addressing scheme.
Wireless LAN Networking13DHCP ServerDHCP (Dynamic Host Configuration Protocol) is a TCP/IP protocol that enablesa host connected to a network to assign a temporary IP address to a clientautomatically when the client connects to the network.The Access Point can function as a DHCP server to dynamically assign IPaddresses and provide other configuration parameters to wireless LAN clientswhen requested by the client. This function reduces the network administrator’sworkload and increases the usage efficiency of the IP addresses by recycling theaddresses when the lease time is up.The DHCP function of the Access Point can be enabled or disabled. You can alsodefine a lower boundary and an upper boundary to establish a range of addressesthat can be assigned. The Access Point can manage a maximum of 256 IPaddresses (0 to 255).In addition to providing an IP address, the Access Point provides the subnetmask, DNS IP address, domain name, gateway IP address, and lease period tocomplete the configuration of the wireless LAN clients. The Access Pointmaintains a mapping table with IP address, MAC (Media Access Control)address, and lease period for each client to control and manage the dynamicconfiguration.
Wireless LAN Access Point User’s Guide14Internet Connection Sharing (ICS)Internet connection sharing (ICS) enables you to configure your network to sharea single connection to the Internet. The Wireless LAN Access Point acts as agateway that allows multiple clients to connect to the Internet by sharing a singlemodem and ISP (Internet Service Provider) account.When a client on your network sends a request to the Internet, its private IPaddress is transmitted to the Access Point, which translates it to the Internet IPaddress (specified by the ISP) of the Access Point, and then sends it on to theInternet. When the results are returned, the Access Point translates the IP addressback again and routes it to the correct client on your network. The only device onyour network visible to the Internet is the Access Point. None of the computers onyour network have a direct connection to the Internet.Wired ClientWireless ClientHub or SwitchAccessPointModemInternet
Wireless LAN Networking15Access Point ManagerWhen Access Point Manager (APM) is installed on a computer in the network,you can change all operating parameters of the Access Point. The APM enablesyou to configure and monitor the operational performance of your network.You can install the APM on as many computers in your network as you want,either wired or wireless. The choice for a wireless or wired computer depends onyour preferences and your network configuration.Verifying the TCP/IP Protocol SettingsAny computer you install the APM on must have TCP/IP networking protocolinstalled to be able to communicate with the Access Point. Using WindowsControl Panel, double-click Network and check that TCP/IP is installed. IfTCP/IP is not installed, install it (refer to TCP/IP Addressing on page 10 for aproper IP addressing).All Access Points areshipped with a factory-set IP Address of192.168.1.1 to allowyour APM computer tocommunicate with newAccess Points.
Wireless LAN Access Point User’s Guide16Configuring Access Point with Wired ClientsIf your Access Point is connected to an established wired network, you can installAPM on any computer on the network. The first time you run APM, you willneed to change the IP address of the Access Point to be compatible with the IPaddress of your network.Wired ClientAccess PointHub or Switch
Wireless LAN Networking17Configuring Access Point with Wireless ClientsIf you want to configure an Access Point from a wireless client, you need toinstall APM on the wireless client. The SSID of the wireless client must matchthe SSID factory setting of the Access Point, or be set to “any”, or left blank.The first time you run APM, you will need to change the IP address of the AccessPoint to be compatible with the IP address of your network.Wireless ClientAccess Point

A set of stations controlled by a single coordination function.Channel A medium used to pass protocol data units that can be used simultaneously in thesame volume of space by other channels of the same physical layer, with anacceptably low frame error ratio due to mutual interference.ESS Extended Service Set. A set of one or more interconnected Basic Service Sets(BSSs) and integrated Local Area Networks (LANs) can be configured as anExtended Service Set.Ethernet The most widely used medium access method, which is defined by the IEEE 802.3standard. Ethernet is normally a shared media LAN; i.e., all the devices on the
Glossary77network segment share total bandwidth. Ethernet networks operate at 10Mbpsusing CSMA/CD to run over 10BaseT cables, which typically use an RJ-45connector.Gateway A network component that acts as an entrance to another network.IEEE 802.11 The IEEE 802.xx is a set of specifications for LANs from the Institute ofElectrical and Electronic Engineers (IEEE). Most wired networks conform to802.3, the specification for CSMA/CD based Ethernet networks or 802.5, thespecification for token ring networks. 802.11 defines the standard for wirelessLANs encompassing three incompatible (non-interoperable) technologies:Frequency Hopping Spread Spectrum (FHSS), Direct Sequence Spread Spectrum(DSSS), and Infrared.Infrastructure A wireless network centered around an Access Point. In this environment, theAccess Point not only provides communication with the wired network but alsomediates wireless network traffic in the immediate neighborhood.IP Internet Protocol. The standard protocol within TCP/IP that defines the basic unitof information passed across an Internet connection by breaking down datamessages into packets, routing and transporting the packets over networkconnections, then reassembling the packets at their destination. IP corresponds tothe network layer in the ISO/OSI model.IP Address An IP address is a 32-bit number that identifies each sender or receiver ofinformation sent across the Internet. An IP address has two parts: the identifier ofa particular network on the Internet and an identifier of the particular device(which can be a server or a workstation) within that network.
Wireless LAN Access Point User’s Guide78ISP Internet Service Provider. An organization that provides access to the Internet.Small ISPs provide service via modem and ISDN while the larger ones also offerprivate line hookups (T1, fractional T1, etc.).LAN Local Area Network. A communications network that serves users within adefined geographical area. The benefits include the sharing of Internet access,files, and equipment, such as printers and storage devices. Special networkcabling (10BaseT) is often used to connect the PCs together.MAC Address Media Access Code Address. A unique, 48-bit number assigned to networkinterface cards by the manufacturer. MAC addresses are used for mapping inTCP/IP network communication.NAT Network Address Translation. The translation of an Internet Protocol address (IPaddress) used within one network to a different IP address known within anothernetwork. One network is designated the internal network and the other is theexternal. The internal network then appears as one entity to the outside world.PCMCIA Personal Computer Memory Card International Association. This Associationdevelops standards for PC cards, formerly known as PCMCIA cards. These cardsare available in three types, and are about the same length and width as creditcards. However, the different cards range in thickness from 3.3 mm (Type I) to5.0 mm (Type II) to 10.5 mm (Type III). These cards can be used for variousfunctions, including memory storage, landline modems, and wireless modems.PS Power Save Mode. This mode is recommended for devices where powerconsumption is a major concern, such as battery-powered devices.Radio Frequency RF, Terms: GHz, MHz, Hz —The international unit for measuring frequency isHertz (Hz), equivalent to the older unit of cycles per second.
