Introduction

This User’s Guide contains information on how to install and configure your Wireless LAN Access Point.

A local area network (LAN) is a network that exists in a relatively limited area. A network is two or more computers connected together sharing files and peripheral devices, such as printers.

A wireless LAN allows you to interact with other computers without having to run cables normally associated with networks, and the Wireless LAN Access Point allows computers equipped with wireless LAN cards (wireless clients) to have access to an existing wired LAN, forming an infrastructure wireless network.

The Access Point is capable of being used in a wide variety of applications, and offers the following functions:

• stand-alone wireless intranet relay station that increases communication range

• wireless access to Ethernet intranet

• wireless access to Internet

• DHCP server to automate IP address assignment

• Internet connection to a single ISP shared by multiple wireless intranet clients

Wireless LAN Networking

Introduction to Networks

A network is a group of computers and associated devices that can communicate with each other through permanent connections, such as cables, or temporary connections made through telephone or other communication links. A network can 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 computers distributed 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 Networks

A wireless LAN is a network that uses radio signals to send and receive data between individual devices. Wireless LANs are often used in office or factory settings where a user must carry a portable computer from place to place. Wireless LANs are also becoming a popular and convenient way of connecting computers 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 the Wireless LAN Access Point, the wireless LAN can be connected to a wired network.

The Wireless LAN Access Point provides connectivity between wireless clients and Ethernet (wired) clients. The Access Point complies with the IEEE 802.11 standard, enabling communication among all wireless clients that meet this standard.

Wireless LAN Networking

Wireless LAN Access Point User’s Guide

Stand-Alone Wireless Network

The stand-alone wireless network is the simplest use of an Access Point. In this configuration, the Access Point acts as a relay between wireless clients. This enables the transfer of information among all computers within the Access Point coverage area.

To communicate with the Access Point and other computers in the network, the Access 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 the communication distance between two computers.

Infrastructure Network

In an infrastructure network, the Access Point connects clients to a wired network. This enables the wireless clients to access all computers and peripherals on the wired network.

Multiple Access Points can be used to achieve seamless wireless access throughout an extended service area. All Access Points and wireless clients must have the same Group ID. Roaming among different Access Points is controlled automatically to maintain the wireless connection at all times.

TCP/IP Addressing

TCP/IP (Transmission Control Protocol/Internet Protocol) has become the standard for network data transmission. The Wireless LAN Access Point uses TCP/IP addressing to communicate between both wired and wireless clients.

For correct IP address information for your wireless LAN installation, contact your network administrator.

For more information on IP addresses, see the Network Working Group Specification RFC 1918 on the Internet.

If you are installing the Wireless LAN Access Point into a wired LAN, you must obtain a static IP address and a subnet mask for the Access Point from the wired network administrator. See Configuring the Wireless LAN Settings.

If you don’t have a network administrator, you will have to select an IP address from one of the available blocks of addresses.

Selecting an IP Address

An IP address consists of four components. Each component can contain up to 256 numbers (0 to 255). Thus, you can select a unique address from a range of addresses (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 the following three blocks are available:

Define your network by determining the number of addresses you will need (allow for expansion).

10. 0 . 0. 0 — 10.255.255.255

172. 16. 0. 0 — 172. 31.255.255

192.168. 0. 0 — 192.168.255.255

Wireless LAN Networking

For example:

If your network will consist of 10 wired clients and 10 wireless clients, you could define the first 3 components of your address as 10.100.100. Next, you would define the fourth component range. You need 20 (allowing for an expansion of 10) addresses for your wired clients and 20 (allowing for an expansion of 10) addresses for your wireless clients.

You could then reserve a block of addresses for the wired clients of

10.100.100.0 through 10.100.100.19 and another block for wireless clients of

10.100.100.20 through 10.100.100.39. Now you can start assigning appropriate addresses to individual clients.

Wireless LAN Access Point User’s Guide

Creating a Subnet Mask

In addition to an IP address, you will need to define a subnet mask to ensure that your computers only communicate with other computers and devices that are within your network.

A subnet mask has four components that correspond to the four components of the IP address. Like the IP address, each component can contain up to 256 numbers (0 to 255). These numbers determine if an IP address component must be 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 be an exact match for communication to take place. If the mask number is 0, any number in the component is acceptable. A mask number between 0 and 255 determines 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 are acceptable.

For example: if you choose an IP address of 10.100.100.1 and a subnet mask of

255.255.255.0, the first three components of the IP address must match exactly, and any number from 0 to 255 in the fourth component is acceptable for communication to take place.

The use of these addresses and masks is limited only by your imagination. You can use any rationale you like to select your addressing scheme.

DHCP Server

DHCP (Dynamic Host Configuration Protocol) is a TCP/IP protocol that enables a host connected to a network to assign a temporary IP address to a client automatically when the client connects to the network.

The Access Point can function as a DHCP server to dynamically assign IP addresses and provide other configuration parameters to wireless LAN clients when requested by the client. This function reduces the network administrator’s workload and increases the usage efficiency of the IP addresses by recycling the addresses when the lease time is up.

The DHCP function of the Access Point can be enabled or disabled. You can also define a lower boundary and an upper boundary to establish a range of addresses that can be assigned. The Access Point can manage a maximum of 256 IP addresses (0 to 255).

In addition to providing an IP address, the Access Point provides the subnet mask, DNS IP address, domain name, gateway IP address, and lease period to complete the configuration of the wireless LAN clients. The Access Point maintains a mapping table with IP address, MAC (Media Access Control) address, and lease period for each client to control and manage the dynamic configuration.

Wireless LAN Networking

Wireless LAN Access Point User’s Guide

Internet Connection Sharing (ICS)

Internet connection sharing (ICS) enables you to configure your network to share a single connection to the Internet. The Wireless LAN Access Point acts as a gateway that allows multiple clients to connect to the Internet by sharing a single modem and ISP (Internet Service Provider) account.

When a client on your network sends a request to the Internet, its private IP address is transmitted to the Access Point, which translates it to the Internet IP address (specified by the ISP) of the Access Point, and then sends it on to the Internet. When the results are returned, the Access Point translates the IP address back again and routes it to the correct client on your network. The only device on your network visible to the Internet is the Access Point. None of the computers on your network have a direct connection to the Internet.

Access Point Manager

When Access Point Manager (APM) is installed on a computer in the network, you can change all operating parameters of the Access Point. The APM enables you 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 on your preferences and your network configuration.

Verifying the TCP/IP Protocol Settings

Any computer you install the APM on must have TCP/IP networking protocol installed to be able to communicate with the Access Point. Using Windows Control Panel, double-click Network and check that TCP/IP is installed. If TCP/IP is not installed, install it (refer to TCP/IP Addressing on page 10 for a proper IP addressing).

Wireless LAN Access Point User’s Guide

Configuring Access Point with Wired Clients

If your Access Point is connected to an established wired network, you can install APM on any computer on the network. The first time you run APM, you will need to change the IP address of the Access Point to be compatible with the IP address of your network.

Setting Up DHCP Service

The DHCP (Dynamic Host Configuration Protocol) Service enables the Access Point host computer to assign available IP addresses dynamically to other computers on the network. The Access Point host computer assigns IP addresses on an as-needed basis and controls the traffic between those computers and the Internet.

To find addresses on the Internet, your computer needs to connect to a Domain Name Service (DNS) computer, called a DNS server. The DNS server answers DNS queries and keeps a database of host computers and their corresponding IP addresses. The DNS Server Address is the IP address of the computer to which the Access Point is connected.

The Boundary area is where the range of IP addresses for computers connected to the Access Point wireless LAN are defined, using the fourth component of the IP Address.

To set up DHCP Service:

1. In the Access Point Configuration dialog box, click the DHCP Service tab.

2. Select the DHCP Service check box.

3. In the DNS Server Address box, enter the IP Address for the DHCP Server.

Glossary

10BaseT An IEEE standard (802.3) for operating 10 Mbps Ethernet networks (LANs) with

twisted pair cabling and a wiring hub.

Access Point An internetworking device that seamlessly connects wired and wireless networks.

Several Access Points combined with a distributed system support the creation of multiple radio cells that enable roaming throughout a facility.

Ad Hoc A network composed solely of stations within mutual communication range of

each other (no Access Point connected).

BSS Basic Service Set. 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 the

same volume of space by other channels of the same physical layer, with an acceptably 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 an Extended Service Set.

Ethernet The most widely used medium access method, which is defined by the IEEE 802.3

standard. Ethernet is normally a shared media LAN; i.e., all the devices on the

Glossary

network segment share total bandwidth. Ethernet networks operate at 10Mbps using CSMA/CD to run over 10BaseT cables, which typically use an RJ-45 connector.

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 of

Electrical and Electronic Engineers (IEEE). Most wired networks conform to

802.3, the specification for CSMA/CD based Ethernet networks or 802.5, the specification for token ring networks. 802.11 defines the standard for wireless LANs 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, the

Access Point not only provides communication with the wired network but also mediates wireless network traffic in the immediate neighborhood.

IP Internet Protocol. The standard protocol within TCP/IP that defines the basic unit

of information passed across an Internet connection by breaking down data messages into packets, routing and transporting the packets over network connections, then reassembling the packets at their destination. IP corresponds to the network layer in the ISO/OSI model.

IP Address An IP address is a 32-bit number that identifies each sender or receiver of

information sent across the Internet. An IP address has two parts: the identifier of a 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 Guide

ISP Internet Service Provider. An organization that provides access to the Internet.

Small ISPs provide service via modem and ISDN while the larger ones also offer private line hookups (T1, fractional T1, etc.).

LAN Local Area Network. A communications network that serves users within a

defined geographical area. The benefits include the sharing of Internet access, files, and equipment, such as printers and storage devices. Special network cabling (10BaseT) is often used to connect the PCs together.

MAC Address Media Access Code Address. A unique, 48-bit number assigned to network

interface cards by the manufacturer. MAC addresses are used for mapping in TCP/IP network communication.

NAT Network Address Translation. The translation of an Internet Protocol address (IP

address) used within one network to a different IP address known within another network. One network is designated the internal network and the other is the external. The internal network then appears as one entity to the outside world.

PCMCIA Personal Computer Memory Card International Association. This Association

develops standards for PC cards, formerly known as PCMCIA cards. These cards are available in three types, and are about the same length and width as credit cards. However, the different cards range in thickness from 3.3 mm (Type I) to

5.0 mm (Type II) to 10.5 mm (Type III). These cards can be used for various functions, including memory storage, landline modems, and wireless modems.

PS Power Save Mode. This mode is recommended for devices where power

consumption is a major concern, such as battery-powered devices.

Radio Frequency RF, Terms: GHz, MHz, Hz —The international unit for measuring frequency is

Hertz (Hz), equivalent to the older unit of cycles per second. One megahertz

Glossary

(MHz) is one Million-Hertz. One gigahertz (GHz) is one Billion-Hertz. The standard U.S. electrical power frequency is 60 Hz, the AM broadcast radio frequency band is 0.55–1.6 MHz, the FM broadcast radio frequency band is 88–108 MHz, and wireless 802.11 LANs operate at 2.4GHz.

SSID Service Set ID. A group name shared by every member of a wireless network.

Only client PCs with the same SSID are allowed to establish a connection.

Subnet Mask A value that defines whether your computer communicates only within your LAN

or communicates outside of your LAN, where it is routed out to the rest of the Internet. A Subnet Mask that has the same first three components (for example,

255.255.255.0) is the routing pattern for a Class C address.

TCP Transmission Control Protocol. The standard transport level protocol that

provides the full duplex, stream service on which many applications’ protocols depend. TCP allows a process on one machine to send a stream of data to a process on another. Software implementing TCP usually resides in the operating system and uses the IP to transmit information across the network.

WEP Wired Equivalent Privacy. The optional cryptographic confidentiality algorithm

specified by 802.11 used to provide data confidentiality that is subjectively equivalent to the confidentiality of a wired LAN medium that does not employ cryptographic techniques to enhance privacy.
