4 Checking the LED IndicatorsWhen the Bridge is connected to power, LEDs indicate activity as follows (solid LED indicates connection; blinking LED indicates activity):5 Attaching An External AntennaThe Bridge has two internal diversity dual-band antennas. If you want to increase the range of the Bridge, an external antenna can be attached to the external antenna connector on the Bridge. The 3Com-approved external antenna for this Bridge is the 3Com 2.4/5 GHz Omnidirectional Workgroup Bridge Antenna (3CWE501). For more information, go to www.3Com.com6 Determining if you Need to Configure the BridgeIf your network has a DHCP server and no special security requirements, you can most likely use the Bridge just as it is shipped from the factory. View the Bridge’s default settings on the next page to determine whether or not you need to configure the Bridge for your network.It takes about one to two minutes for the Bridge to determine if there is a DHCP server on the network.If your network does not have a DHCP server or is more complex, you will want to configure the Bridge and organize devices so that you can manage the wireless LAN easily and keep it secure.LED Color IndicatesPower GreenOffThe Bridge is powered up and operating normally.The Bridge is not receiving power or there is a fault with the power supply.11a Green OffThe Bridge has WLAN frame transmissions over an 802.11a 5 GHz radio band.No link is present.11g GreenOffThe Bridge has WLAN frame transmissions over an 802.11g 2.4 GHz radio band.No link is present.100 GreenOffThe Bridge has a 100 Mbps Fast Ethernet connection.No link is present.10 GreenOffThe Bridge has a 10 Mbps Ethernet connection.No link is present.CAUTION: For non-U.S. versions of the Bridge, you need to set the Country mode. This is done when you first open the Bridge’s Configuration Management System. Select the Country in which the Bridge is operating and then click Apply..11g.100.10.11a
Networks with a DHCP ServerIf your network has a DHCP server, an IP address is automatically assigned to the Bridge. Use the 3Com Wireless Infrastructure Device Manager (Widman) included on the 3Com Installation CD to locate the Bridge on the network and view its IP address. After you determine the Bridge’s IP address, you can enter that IP address into a web browser on a computer on the same subnet to view the Bridge’s system status or change its configuration.Networks without a DHCP ServerIf your network does not have a DHCP server, the Bridge uses a default IP address (169.254.2.2) that is assigned at the factory. You can use that IP address to configure the Bridge, or you can assign a new IP address to the Bridge. To verify that the Bridge is using the default IP address assigned at the factory:1Connect a computer directly to the Bridge using the supplied standard Category 5 UTP Ethernet cable. 2Enter the Bridge’s default IP address (169.254.2.2) into the computer’s web browser.If the Configuration Management System starts, the Bridge is using the factory assigned IP address. You can configure the Bridge with the following login information:■Login name: admin ■Password: none (blank)If the Configuration Management System does not start, the Bridge is on a different subnet than the computer. Install and start the 3Com Wireless Infrastructure Device Manager to discover the Bridge’s IP address.Bridge Default SettingsThe table below shows the Bridge configuration factory defaults.Property Default SettingDevice Name 3Com WWBDevice Location NoneCountry For U.S. versions, United States and CanadaFor non-U.S. version, set by the userClient Mode Support multiple wired Ethernet clientsIP Network Setting Obtain IP address automatically IP Address Obtained automatically (with a DHCP server)169.254.2.2 (without a DHCP server)Subnet Mask Obtained automatically (with a DHCP server)255.255.0.0 (without a DHCP server)Gateway IP Address Obtained automatically (with a DHCP server)0.0.0.0 (without a DHCP server)Network Mode Wireless Client (Infrastructure)Radio Mode Auto SelectWireless LAN Service Area Attach to any WLAN Service Area (ESSID) automaticallyChannel Selection Automatic Best Channel (uses access point setting)Transmit Power 100%

1INTRODUCTION3Com wireless technology has all of the benefits of a local area network (LAN) without the constraints and expense of network wiring. 3Com 11a/b/g Wireless LAN products provide easy, affordable, flexible ways to extend wireless networks to more users. This guide shows how you can use the 3Com 11a/b/g Wireless Workgroup Bridge in your office or classroom to connect groups of wired Ethernet client devices to your wireless LAN.Product Features The 3Com 11a/b/g Wireless Workgroup Bridge includes a robust suite of standards-based security features, and supports wireless network standards including 802.11a and 802.11g.Security To protect sensitive data broadcast over the radio, 3Com supports Wireless Equivalent Privacy (WEP) RC4 64-bit, 128-bit and 152-bit shared-key encryption. 3Com strengthens this basic security mechanism with additional security features, including:■MAC address access control lists■IEEE 802.1x per-port user authentication with RADIUS server authentication support■Temporal Key Integrity Protocol (TKIP)■Advanced Encryption Standard (AES)■WiFi Protected Access (WPA)■Extensible Authentication Protocol (EAP) support: EAP-TTLS and PEAP
6CHAPTER 1: INTRODUCTIONWireless NetworkStandardsUnderstanding the characteristics of the 802.11a and 802.11g standards can help you make the best choice for your wireless implementation plans.802.11aRatified in 2002, 802.11a is IEEE’s more recent wireless standard. It operates at the 5 GHz band and supports data rates at up to 54 Mbps. For those organizations demanding even higher speeds, a “turbo mode” feature can boost throughput rates up to 108 Mbps. And because there are fewer devices in the 5 GHz band, there’s less potential for RF interference. However, because it is at an entirely different radio spectrum, it is not compatible with 802.11g.The higher spectrum provides about 50 m (164 ft) of coverage—about half what 802.11g offers.Consider 802.11a when you need high throughput in a confined space and you are:■Running high-bandwidth applications like voice, video, or multimedia over a wireless network that can benefit from a five-fold increase in data throughput.■Transferring large files like computer-aided design files, preprint publishing documents or graphics files, such as MRI scans for medical applications, that demand additional bandwidth.■Supporting a dense user base confined to a small coverage area. Because 802.11a has a greater number of non-overlapping channels, you can pack more wireless devices in a tighter space.802.11g802.11g operates in the 2.4 GHz band at up to 54 Mbps. Ratified in 2003, it supports the widest coverage—up to 100 m (328 ft). However, is subject to a greater risk of radio interference because it operates in the more popular 2.4 GHz band.802.11b operates at up to 11 Mbps and supports coverage up to 100 m (328 ft).
Network Configuration and Planning 7Consider 802.11g when you need wider coverage and vendor compatibility and you are:■Maintaining support for existing 802.11b users and the existing wireless investment while providing for expansion into 802.11g.■Implementing a complete wireless LAN solution, including bridges, gateways, access points and clients; Wi-Fi certification guarantees compatibility among vendors.■Providing access to hot spots in public spaces such as coffee shops or university cafeterias.Network Configuration and PlanningThe Bridge can operate in either infrastructure or ad-hoc mode, and can support a stand-alone wireless network configuration or an integrated configuration with 10/100 Mbps Ethernet LANs.Operating in infrastructure mode and connected to an Ethernet hub, a single Bridge can combine up to 16 client devices—such as computers with network adapters and printers—into a multiclient workgroup. The workgroup associates with the wired network through a wireless LAN access point such as the 3Com 11a/b/g Wireless LAN Access Point. Infrastructure configurations extend your wireless LAN to devices that would otherwise have to be connected to the wired network.Operating in ad-hoc mode, two or more Bridges can associate among themselves and communicate with one another at close range without an access point. You may wish to set up an ad-hoc network, for example, if a group is working away from the office, or if a group in the office needs to share files apart from the wired LAN.
8CHAPTER 1: INTRODUCTIONExample ConfigurationsThe following examples illustrate ways you can use the Bridge to configure Ethernet client devices into workgroups. (Details for setting up specific configurations are in “Installing the Bridge” on page 9.)Wireless Infrastructure NetworkYou can connect several computers, including those with non-Windows operating systems, and network printers, as shown in Figure 1.Figure 1 Wireless Infrastructure NetworkWorkgroup Ad-Hoc NetworkYou can provide flexible wireless network association for small groups in areas that cannot be wired, as shown in Figure 2.Figure 2 Workgroup Ad-Hoc NetworkPOWERPOWERETHERNETETHERNETWIRELESSWIRELESSPOWERPOWERETHERNETETHERNETWIRELESSWIRELESS.11g.100.10.11aAccessPointHub11a/b/g WirelessWorkgroup Bridge.11g.100.10.11a11a/b/g WirelessWorkgroup Brid geHub.11g.100.10.11a11a/b/g WirelessWorkgroup Brid geHub

Connecting the Bridge 15Connecting to anEthernet DeviceThe Bridge is designed to be connected to an Ethernet client device such as a hub, computer, or printer.CAUTION: To avoid the possibility of a transmission loop situation between the Bridge and an access point, which could disrupt network operation, do not connect a Bridge that is set in Wireless Client (Infrastructure) mode directly to the LAN (for example, through a wall port or through a hub that is connected directly to the LAN).About the Client List The Bridge supports up to 16 specific Ethernet client devices. It uses a client list of MAC addresses to keep track of specific devices that have been connected. After 16 different devices have been connected, the client list is full, and you must clear it before the next new device can associate with the network through the Bridge. To clear the list, you must access the Bridge’s Configuration Management System. Details are in “Clearing the Ethernet Client List” on page 45.Connecting to a Hub You can supply network connections for up to 16 devices, such as computers and network printers, by connecting the Bridge to an Ethernet hub, as shown in Figure 10.Figure 10 Connecting to a HubYou can directly connect the Bridge to a hub that does not have an uplink (MDIX) port, without the need of an Ethernet crossover cable..11g.100.10.11aHub11a/b/g WirelessWorkgroup Brid geUplink PortAccessPointPOWERPOWERETHERNETETHERNETWIRELESSWIRELESS
16 CHAPTER 2: INSTALLING THE BRIDGEConnecting to aNetwork PrinterYou can connect a network printer directly to the Bridge or to a hub that is connected to the Bridge. Used this way, the Bridge allows you to place network printers in areas that are not wired for Ethernet.1Configure the network printer as you would for connecting it to the wired LAN. For details on configuring the printer, see your printer documentation.2If necessary, configure the Bridge to associate with your access point.3Connect the Bridge to the power supply in its permanent location.4Connect the network printer directly to the Bridge as shown in Figure 11, or to a hub that is connected to the Bridge as shown in “Connecting to a Hub” on page 15.Figure 11 Connecting to a Network PrinterConnecting to aComputerYou can connect the Bridge directly to a computer as shown in Figure 12. Used this way, the Bridge can convert a desktop computer to a wireless computer. This connection also allows you to configure a Bridge before connecting it to another device.Figure 12 Connecting to a Computer.11g.100.10.11a11a/b/g WirelessWorkgroup Brid geAccessPointPOWERPOWERETHERNETETHERNETWIRELESSWIRELESS.11g.100.10.11a11a/b/gWirelessWorkgroupBridgeAccessPointPOWERPOWERETHERNETETHERNETWIRELESSWIRELESS

18 CHAPTER 2: INSTALLING THE BRIDGEAttaching An External AntennaThe Bridge has two internal diversity dual-band antennas. If you want to increase the range of the Bridge, an external antenna can be attached to the external antenna connector on the Bridge. The 3Com-approved external antenna for this Bridge is the 3Com 2.4/5 GHz Omnidirectional Workgroup Bridge Antenna (3CWE501). For more information, go to www.3Com.comDetermining if you Need to Configure the BridgeIf your network has a DHCP server and no special security requirements, you can most likely use the Bridge just as it is shipped from the factory. It takes approximately one to two minutes for the Bridge to determine if there is a DHCP server on the network.View the Bridge’s default settings on page 20 to determine whether or not you need to configure the Bridge for your network. If the factory defaults meet your requirements, you can connect the Bridge as described in “Connecting the Bridge” on page 14.If your network does not have a DHCP server or is more complex, you may have to configure the Bridge and organize devices so that you can manage the wireless LAN easily and keep it secure. You can use the 3Com Wireless Infrastructure Device Manager (Widman) included on the 3Com Installation CD.For non-U.S. versions of the Bridge, you need to set the Country mode. This is done when you first open the Bridge’s Configuration Management System. See “Using the Configuration Management System” on page 27 for instructions.Networks with a DHCP ServerIf your network has a DHCP server, an IP address is automatically assigned to the Bridge. Use the 3Com Wireless Infrastructure Device Manager (Widman) included on the 3Com Installation CD to locate the Bridge on the network and view its IP address. Alternatively, you can enter the Bridge’s IP address into a web browser on a computer on the same subnet to view the Bridge’s system status or change its configuration. See “Configuring the Bridge” on page 23 for instructions.
Determining if you Need to Configure the Bridge 19Networks without a DHCP ServerIf your network does not have a DHCP server, the Bridge uses a default IP address (169.254.2.2) that is assigned at the factory. You can use that IP address to configure the Bridge, or you can assign a new IP address to the Bridge. To verify that the Bridge is using the default IP address assigned at the factory:1Connect a computer directly to the Bridge using the supplied standard Category 5 UTP Ethernet cable. See Figure 12 on page 16 for a connection diagram.2Enter the Bridge’s default IP address (169.254.2.2) into the computer’s web browser.■If the Configuration Management System starts, the Bridge is using the factory assigned IP address. You can configure the Bridge with the following login information:■Login name: admin ■Password: none (blank)See “Configuring the Bridge” on page 23 for detailed instructions.■If the Configuration Management System does not start, the Bridge is on a different subnet than the computer. Install and start the 3Com Wireless Infrastructure Device Manager to discover the Bridge’s IP address. See “Using the 3Com Wireless Infrastructure Device Manager” on page 24 for instructions.

The Bridge can be configured to support three types of data encryption: WEP, TKIP, and AES. After selecting a data encryption type, you can select an authentication type.The following sections describe the settings. To maintain wireless association, the settings on clients and the access points they associate with (or other members of an ad-hoc network) must match exactly.No Security (Open System)No encryption is used. The network communications could be intercepted by unintended recipients.40/64-bit Shared Key (WEP)This option encrypts the wireless transmissions to protect data, but still allows communication among compatible wireless LAN clients and access points from third-party manufacturers that are Wi-Fi certified.This type of security requires you to set up encryption in one of the following ways:■String—For use only with other 3Com 11a/b/g wireless devices, an encryption string is a case-sensitive string of characters between 6 and 30 characters long. To enter the string, select Enter a string to generate shared keys. Then type any combination of letters and numbers in the space provided and select Apply.■Shared keys—Hexadecimal keys are sequences of hexadecimal digits arranged into four keys. A hexadecimal digit may be a letter from A to F or a number from 0 to 9. This type of encryption is compatible with equipment from other manufacturers that use Wi-Fi certified 40-bit encryption. To enter the keys, select Specify shared keys and which to use. In the shared keys window, enter all the keys in the provided spaces, then select a radio button in the Selected Key column to specify which key to use and select Apply.

Using the Configuration Management System 39Serial Port Under System Configuration, click Serial Port to set up network serial port operation.About UARTA Universal Asynchronous Receiver/Transmitter (UART) is the fundamental hardware for serial communication, controlling the speed and method of data transfer of the serial port. Applications utilizing a network serial port between an RS-232 interface and a wireless device use a TCP/IP socket connection. Any program that uses standard TCP/IP network sockets may be used to communicate with the serial port of the Bridge. Once a socket is established to the Bridge, any data written to the socket is sent out the serial port of the Bridge. At the same time, any data received by the serial port of the Bridge is returned via the socket connection.The Bridge network serial port may be used in two modes:■Server Mode — TCP Listen Port■Client Mode — TCP Connect PortIn Server Mode, the Bridge waits for a TCP/IP socket connection to be made by the network program with which it will communicate. Server Mode should be used if you have a central server that expects to open a TCP/IP socket connection to the Bridge.In Client Mode, the Bridge establishes a socket connection to the IP address and port number specified in the configuration. Client Mode should be used if your system expects the Bridge to open a TCP/IP socket connection to a central server.Configuring UART SettingsFor proper operation, it is imperative that these settings always match the settings of the device to which the bridge is connected via the RS-232 port. There are two groups of parameters that need to be configured to accomplish this task: UART Settings and Flow Control Settings.Flow control is the process of adjusting the flow of data from one device to another to ensure that the receiving device can handle all of the incoming data.
40 CHAPTER 3: CONFIGURING THE BRIDGETo configure the UART settings:1Select the baud rate of your device.The baud rate indicates the data transfer rate of the serial port. The baud rate ranges from 300 to 115200 bits per second (bps). Standard rates are 300, 1200, 2400, 9600, 19200, 38400, 57600, 115200.2Determine the data bits setting of the device you are connecting to the Bridge, then set the Data Bits setting for the bridge that matches the data bits setting of that device.The Data Bits setting determines the number of bits used to transmit data. The possible values are 7 and 8.3Determine the stop bits setting of the device you are connecting to the Bridge, then set the Stop Bits setting on the Bridge that matches the stop bits setting of that device.The Stop Bits setting determines the number of bits used to represent an end of a character. The value can be 1 or 2.4Determine the parity bit setting of the device you are connecting to the Bridge, then set the Parity Bit setting on the Bridge that matches the parity bit setting of that device.The Parity Bit setting is used to check for correct data transmission. Options are: none, even, and odd.5Set the flow control setting.Flow control becomes an important factor when one of the devices is capable of transmitting data at a rate faster than the other can receive it. There are two basic types of flow control, hardware and software.Configuring Operation Mode■Select CLI Console if you want to configure the Bridge through CLI commands. Attach your computer to the serial port on the Bridge, and then configure the Bridge through the computer. ■Select Network Serial Port to establish a TCP/IP socket with a remote computer in either infrastructure or ad-hoc mode. This allows you to do data communication with the remote computer, rather than configure the Bridge.
Using the Configuration Management System 41Configuring Network Serial Port SettingsFor Server Mode, click Server Mode and enter the port number to which the Bridge connects in the List on port field. The default port number is 4000.For Client Mode, select Client Mode and enter the IP address and port number to which the Bridge connects. The default port number is 4000.Applying SettingsAfter you set the UART settings, operation mode, and network serial port settings, select Apply to make the settings take effect.The socket can be substantially established between a client and server; that is, a Bridge in server mode and the other in client mode. The Bridge with the Network Serial Port option set cannot work alone. Generally, a Bridge is set to server mode first, which listens to a designated port. The other Bridge is then set to client mode, which connects to the designated port on the IP address of the Bridge set to server mode.Resetting the Bridge If the Bridge stops responding correctly, you can perform a reset, which disrupts the network association temporarily, but does not affect Bridge configuration settings that have already been applied with Apply.To reset the Bridge, under Tools, click Reset Wireless Workgroup Bridge. In the next page, click Reset.The Bridge can also be reset using the Wireless Infrastructure Device Manager (Widman). Right-click the Bridge in Widman, and then select Reset.
42 CHAPTER 3: CONFIGURING THE BRIDGERestoring the Bridgeto Factory DefaultsYou can restore Bridge settings to the defaults that were set at the factory either manually or through software. To restore the settings manually, insert a pointed object (such as the end of a straightened paper clip) into the reset hole on the back of the unit near the RJ-45 connector and hold for five seconds.To restore the settings through software:1Under Tools, click Restore Factory Defaults.2Click Restore.If the Bridge was using an IP address setting other than the default, restoring the factory defaults will change the IP address. If you want to continue configuring the Bridge, do the following:1Close your browser.2Return to the 3Com Wireless Infrastructure Device Manager and click Refresh.3Select the device and click Configure to start a new configuration session.Upgrading theSystemYou can download firmware updates or updates of the Configuration Management System from the 3Com Web site and install those updates on the Bridge.Options for upgrading the system include using a Trivial File Transfer Protocol (TFTP) server or File Transfer Protocol (FTP) server. The Bridge acts as a TFTP or FTP client to receive the download. Alternatively, you an use the HTTP option and upload the firmware from a downloaded file placed on your computer.Information regarding upgrade availability and procedures can be obtained from the 3Com Web site as follows:1Log on to the 3Com Web site at http://www.3com.com.2Navigate to the product support page for the 3Com 11a/b/g Wireless Bridge to access the downloads and instructions.3Follow the instructions at the 3Com Web site.

Disconnecting the Bridge 49Disconnecting the BridgeTo disconnect the Bridge:CAUTION: Disconnecting the Bridge ends the network association. To avoid possible data loss, exit all networking applications on connected devices before you disconnect the Bridge.1Unplug the Bridge Ethernet cable from the hub or other device.2Unplug the Bridge power cord.Uninstalling Software and DocumentationIf you want to uninstall the 3Com 11a/b/g Wireless Workgroup Bridge software and documentation, you can either use the standard operating system procedure for removing programs or use the following shortcut procedure:1From the Windows Start menu, select Start > Programs > 3Com Wireless > Uninstall 3Com Wireless Infrastructure Device Manager.2When prompted to confirm, click OK.Upgrading Bridge FirmwareFirmware is the software that is installed on the Bridge at the factory. Some problems can be solved by installing a new version of the firmware. For details on how to download a firmware update from the 3Com customer support Web site and install it on your Bridge, see “Upgrading the System” on page 42You are running Windows NT. After you connect the Bridge, your computer cannot obtain a valid IP address.The Bridge configuration settings may not be compatible with the network. If they are not, and your Windows NT computer is set up to obtain its IP address from a DHCP server, the Bridge is unable to associate with the network to obtain the IP address. To work around this problem, set a static IP address on your computer. Then set the Bridge configuration to match the network. When the Bridge is able to associate, reset your computer to obtain its IP address from the DHCP server. If the Bridge should also obtain its IP settings from the DHCP server, make sure this is configured properly on the IP Network page and applied just before ending the session.Table 15 Troubleshooting (continued)
ACOMMAND-LINE INTERFACEThe Bridge can be configured through the command line interface (CLI). The CLI allows viewing and modification of the Bridge configuration from a terminal or PC through a Telnet connection. Logging In To access the CLI, use Telnet to log in to the Bridge using its IP address. The CLI prompts for a login user name and password and displays a version banner and a CLI prompt.
