6ABOUT THIS GUIDE

1INTRODUCTIONEnterasys Networks wireless technology has all of the benefits of a local area network (LAN) without the constraints and expense of network wiring. Enterasys Networks 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 Enterasys Networks 11a/b/g Wireless Ethernet Adapter in your office or classroom to connect groups of wired Ethernet client devices to your wireless LAN.Product Features The Enterasys Networks 11a/b/g Wireless Ethernet Adapter 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, Enterasys Networks supports Wireless Equivalent Privacy (WEP) RC4 64-bit, 128-bit and 152-bit shared-key encryption. Enterasys Networks 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

8CHAPTER 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. 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 9Consider 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 Ethernet Adapters, 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 Ethernet Adapter 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 Ethernet Adapter 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 Enterasys Networks 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 Ethernet Adapters 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.

10 CHAPTER 1: INTRODUCTIONExample ConfigurationsThe following examples illustrate ways you can use the Ethernet Adapter to configure Ethernet client devices into workgroups. (Details for setting up specific configurations are in “Installing the Ethernet Adapter” on page 11.)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 NetworkPOWERPOWERETHERNETETHERNETWIRELESSWIRELESSPOWERPOWERETHERNETETHERNETWIRELESSWIRELESSAccessPoint11a/b/g Wireless Ethernet AdapterHub11a/b/g Wireless Ethernet AdapterHub11a/b/g Wireless Ethernet AdapterHub

16 CHAPTER 2: INSTALLING THE ETHERNET ADAPTERConnecting to anEthernet DeviceThe Ethernet Adapter 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 Ethernet Adapter and an access point, which could disrupt network operation, do not connect a Ethernet Adapter 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).VORSICHT: Um eine Übertragungsschleife zwischen dem Ethernet-Adapter und einem Access Point zu verhindern, die den Netzwerkbetrieb stören könnte, darf ein im Modus Wireless Client (Infrastructure) (Drahtloser Client [Infrastruktur]) eingerichteter Ethernet-Adapter nicht direkt mit dem LAN verbunden werden (z. B. über eine Wandbuchse oder über einen direkt mit dem LAN verbundenen Hub).About the Client List The Ethernet Adapter 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 Ethernet Adapter. To clear the list, you must access the Ethernet Adapter’s Configuration Management System. Details are in “Clearing the Ethernet Client List” on page 49.

Connecting the Ethernet Adapter 17Connecting to a Hub You can supply network connections for up to 16 devices, such as computers and network printers, by connecting the Ethernet Adapter to an Ethernet hub, as shown in Figure 8.Figure 8 Connecting to a HubYou can directly connect the Ethernet Adapter to a hub that does not have an uplink (MDIX) port, without the need of an Ethernet crossover cable.Connecting to aNetwork PrinterYou can connect a network printer directly to the Ethernet Adapter or to a hub that is connected to the Ethernet Adapter. Used this way, the Ethernet Adapter 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 Ethernet Adapter to associate with your access point.3Connect the Ethernet Adapter to the power supply in its permanent location.4Connect the network printer directly to the Ethernet Adapter as shown in Figure 9, or to a hub that is connected to the Ethernet Adapter as shown in “Connecting to a Hub” on page 17.Figure 9 Connecting to a Network PrinterHub11a/b/g Wireless Ethernet AdapterUplink PortAccessPointPOWERPOWERETHERNETETHERNETWIRELESSWIRELESS11a/b/g Wireless Ethernet AdapterAccessPointPOWERPOWERETHERNETETHERNETWIRELESSWIRELESS

20 CHAPTER 2: INSTALLING THE ETHERNET ADAPTERAttaching An External AntennaThe Ethernet Adapter has two internal diversity dual-band antennas. If you want to increase the range of the Ethernet Adapter, an external antenna can be attached to the external antenna connector on the Ethernet Adapter. The Enterasys Networks-approved external antenna for this Ethernet Adapter is the Enterasys Networks 2.4/5 GHz Omnidirectional Workgroup Ethernet Adapter Antenna. For more information, go to http://www.enterasys.com/products/wirelessDetermining if you Need to Configure the Ethernet AdapterIf your network has a DHCP server and no special security requirements, you can most likely use the Ethernet Adapter just as it is shipped from the factory. It takes approximately one to two minutes for the Ethernet Adapter to determine if there is a DHCP server on the network.View the Ethernet Adapter’s default settings on page 22 to determine whether or not you need to configure the Ethernet Adapter for your network. If the factory defaults meet your requirements, you can connect the Ethernet Adapter as described in “Connecting the Ethernet Adapter” on page 15.If your network does not have a DHCP server or is more complex, you may have to configure the Ethernet Adapter and organize devices so that you can manage the wireless LAN easily and keep it secure. You can use the Enterasys Networks Wireless Infrastructure Device Manager (Widman) included on the Enterasys Networks Installation CD.For non-U.S. versions of the Ethernet Adapter, you need to set the Country mode. This is done when you first open the Ethernet Adapter’s Configuration Management System. See “Using the Configuration Management System” on page 29 for instructions.Networks with a DHCP ServerIf your network has a DHCP server, an IP address is automatically assigned to the Ethernet Adapter. It takes approximately one to two minutes for the Ethernet Adapter to determine if there is a DHCP server on the network. Use the Enterasys Networks Wireless Infrastructure Device Manager

Determining if you Need to Configure the Ethernet Adapter 21(Widman) included on the Enterasys Networks Installation CD to locate the Ethernet Adapter on the network and view its IP address. Alternatively, you can enter the Ethernet Adapter’s IP address into a web browser on a computer on the same subnet to view the Ethernet Adapter’s system status or change its configuration. See “Configuring the Ethernet Adapter” on page 25 for instructions.Networks without a DHCP ServerIf your network does not have a DHCP server, the Ethernet Adapter uses a default IP address (169.254.2.2) that is assigned at the factory. You can use that IP address to configure the Ethernet Adapter, or you can assign a new IP address to the Ethernet Adapter. To verify that the Ethernet Adapter is using the default IP address assigned at the factory:1Connect a computer directly to the Ethernet Adapter using the supplied standard Category 5 UTP Ethernet cable. See Figure 10 on page 18 for a connection diagram.2Enter the Ethernet Adapter’s default IP address (169.254.2.2) into the computer’s web browser.■If the Configuration Management System starts, the Ethernet Adapter is using the factory assigned IP address. You can configure the Ethernet Adapter with the following login information:■Login name: admin ■Password: none (blank)See “Configuring the Ethernet Adapter” on page 25 for detailed instructions.■If the Configuration Management System does not start, the Ethernet Adapter is on a different subnet than the computer. Install and start the Enterasys Networks Wireless Infrastructure Device Manager to discover the Ethernet Adapter’s IP address.

34 CHAPTER 3: CONFIGURING THE ETHERNET ADAPTERSetting DescriptionWireless LAN Service Area Select Attach to any WLAN Service Area (ESSID) automatically to allow the Ethernet Adapter to associate with any access point without specifying the ESSID. In this mode, the Ethernet Adapter uses the ESSID of the access point with the best signal strength. This mode is not available when the network mode is Ad-hoc (Peer-to-Peer).Select Specify the Wireless LAN Service Area to allow the Ethernet Adapter to associate only with access points with the same service area. You may enter the WLAN service area name or select it from the list. You must specify the WLAN service area when the network mode is Ad-hoc (Peer-to-Peer).To maintain a wireless association, the WLAN service area on a Ethernet Adapter and the access point with which it is associated must match exactly. Therefore, if the Ethernet Adapter is set to Specify the WLAN Service Area and you change the access point WLAN service area, make sure to also change the Ethernet Adapter WLAN service area.Channel Selection If Radio Mode is set to Auto Select, you do not have the following options to choose from.When the network mode is Wireless Client (Infrastructure), a user may have the Ethernet Adapter automatically select an appropriate channel by using Automatic Best Channel or specify the channels by using Specify Channel.When the network mode is Ad-hoc (Peer-to-Peer) you may specify channel selection as follows:■Automatic Best Channel—When this option is enabled, the Ethernet Adapter scans the primary channels. If the Ethernet Adapter is establishing a new ad-hoc network, it chooses the channel with the least number of packets. If the Ethernet Adapter is joining an existing ad-hoc network, it selects the channel in use.■Specify Channel—Click the button preceding this option and enter the Advanced Wireless Network page. On this page, you can choose channels from the Channel list.Transmit Power This option specifies the level of transmission power. Select one of the values (100%, 50%, 25%, 12%, min) from the drop-down menu. Decrease the Transmit Power setting if more than one Ethernet Adapter is using the same channel frequency.Table 11 Wireless Network Page (continued)

Using the Configuration Management System 35Manually SelectingRadio ChannelsOn the Advanced Wireless Network page, you can manually select the radio channels and radio modes. The Ethernet Adapter only looks for a best SSID that matches the specified radio mode on the specified channels.Setting Up an Ad-HocNetworkOperating in ad-hoc mode, two or more Ethernet Adapters can associate among themselves to form an ad-hoc network without the intervention of 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.CAUTION: To ensure correct operation, the settings on the two Ethernet Adapters must match exactly. To avoid the possibility of losing wireless association while you are configuring, Enterasys Networks recommends that you connect the Ethernet Adapter directly to the computer.VORSICHT: Um einen fehlerfreien Betrieb zu gewährleisten, müssen die Einstellungen auf den beiden Ethernet-Adaptern genau übereinstimmen. Es wird empfohlen, den Ethernet-Adapter direkt mit dem Computer zu verbinden, um während der Konfiguration die drahtlose Verbindung nicht zu verlieren.Setting DescriptionAntenna Selection Select an antenna for the radio signal:■Internal—this default setting should be used in most circumstances.■External and one internal antenna—this setting automatically determines which antenna is best for sending packets to individually attached clients.

Using the Configuration Management System 41CAUTION: With the Allow option of the System Default Mode selected, the Ethernet Adapter allows all Ethernet frames except those carrying the MAC addresses that are specified in the Access Control List and have the permission type Deny. Similarly, with the Deny option of the System Default Mode selected, the Ethernet Adapter denies all Ethernet frames except those carrying the MAC addresses that are specified in the Access Control List and have the permission type Allow.Make sure that the MAC address of the computer through which you are configuring the Ethernet Adapter is not specified in the Access Control List with the permission type Deny if you want to set the access control type to Allow. If you want to set the Access Control Type to Deny, make sure that the MAC address of the computer is included in the Access Control List with the permission type Allow. Failure to do so results in access to the Ethernet Adapter being blocked; the Ethernet Adapter will no longer be configurable through the computer.VORSICHT: Wenn im System Default Mode (Standardsystemmodus) die Option "Allow" (Zulassen) aktiviert ist, werden im Ethernet-Adapter alle Ethernet-Frames außer denen zugelassen, die in der Zugriffssteuerungsliste angegebene MAC-Adressen enthalten und den Berechtigungstyp "Deny" (Blockieren) besitzen. Wenn im System Default Mode (Standardsystemmodus) die Option "Deny" (Blockieren) aktiviert ist, werden im Ethernet-Adapter dementsprechend alle Ethernet-Frames außer denen gesperrt, die in der Zugriffssteuerungsliste angegebene MAC-Adressen enthalten und den Berechtigungstyp "Allow" (Zulassen) besitzen. Die MAC-Adresse des Computers, über den der Ethernet-Adapter konfiguriert wird, darf daher in der Zugriffssteuerungsliste nicht den Berechtigungstyp "Deny" (Blockieren) besitzen, wenn Sie den Zugriffssteuerungstyp auf "Allow" (Zulassen) festlegen möchten. Soll der Zugriffssteuerungstyp auf Deny (Blockieren) festgelegt werden, muss die MAC-Adresse des Computers in der Zugriffssteuerungsliste enthalten sein und den Berechtigungstyp "Allow" (Zulassen) aufweisen. Andernfalls wird der Zugang zum Ethernet-Adapter blockiert, der dann nicht mehr über den Computer konfiguriert werden kann.6Click Apply.To delete one or more than one client(s) from the Access Control List, select the client(s) and then click Delete.

42 CHAPTER 3: CONFIGURING THE ETHERNET ADAPTERSerial 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 Ethernet Adapter. Once a socket is established to the Ethernet Adapter, any data written to the socket is sent out the serial port of the Ethernet Adapter. At the same time, any data received by the serial port of the Ethernet Adapter is returned via the socket connection. The serial port communicates to the wireless port only. The serial port cannot communicate with the wired Ethernet port.The Ethernet Adapter network serial port may be used in two modes:■Server Mode — TCP Listen Port■Client Mode — TCP Connect PortIn Server Mode, the Ethernet Adapter waits for a TCP/IP socket connection to be made over the wireless port 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 Ethernet Adapter.In Client Mode, the Ethernet Adapter establishes socket connection over the wireless port to the IP address and port number specified in the configuration. Client mode should be used if your system expects the Ethernet Adapter to open a TCP/IP socket connection to a central server.Configuring Operation ModeAttach your computer to the serial port on the Ethernet Adapter, and then configure the Ethernet Adapter through the computer. ■Select Enable 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. ■Select Disable to disable the Network Serial Port.

Using the Configuration Management System 43Configuring UART SettingsFor proper operation, it is imperative that these settings always match the settings of the device to which the Ethernet Adapter 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.To configure the UART settings:1Select the baud rate of your device.The baud rate indicates the data transfer rate of the serial port. 2Determine the data bits setting of the device you are connecting to the Ethernet Adapter, then set the Data Bits setting for the Ethernet Adapter 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 Ethernet Adapter, then set the Stop Bits setting on the Ethernet Adapter 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 Ethernet Adapter, then set the Parity Bit setting on the Ethernet Adapter 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.Configuring Network Serial Port SettingsFor Server Mode, click Server Mode and enter the port number to which the Ethernet Adapter 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 Ethernet Adapter connects. The default port number is 4000.

44 CHAPTER 3: CONFIGURING THE ETHERNET ADAPTERAfter configuring the port mode, you also need to configure the following options:■Line Length – As data arrives on the serial port it is accumulated in a buffer in the Ethernet Adapter. The Line length parameter sets the maximum size for this buffer. When the number of characters in the buffer reaches the Line length value the entire buffer is sent as the data in a single network packet. The value of Line length can range from 1 to 1,408 bytes. The default value is 1,408.Do not use values of line length less than 5 with a serial baud rate of 115,200 or greater.■Timeout – Often serial data arrives in small bursts of characters. When the Ethernet Adapter receives a burst of data it will wait for a certain period of time for additional data to be received. If additional data is received, it is added to the receive buffer, and the Ethernet Adapter begins to wait again. If additional data is not received for longer than the period specified by the Timeout value, then the buffer of characters received is sent in a single network packet, and the process begins again.The value of timeout is in units of milliseconds, and should be specified in 10 millisecond increments. The valid range for timeout is from 10 (0.01 second) to 65,000 (650 seconds). The default value is 10.■Delimiters – Some serial devices transmit and receive data in a known structure. In these cases, there are often special characters that the transmitting device uses to indicate a complete message has been sent. These characters are referred to as delimiters. You can specify up to five different delimiting characters to the Ethernet Adapter. When the Ethernet Adapter adds one of these characters to its buffer of serial received characters, it will immediately send that buffer as a network packet.The value of delimiters is specified as a list of hexadecimal values separated by spaces. You may specify up to five different delimiter values. For example, if you want to use the delimiter 41375, you must type the following hex values:0x34 0x31 0x33 0x39 0x35If you are unsure of the hex value for your delimiter character, consult the Web page www.asciitable.com for reference.

Using the Configuration Management System 45Applying SettingsAfter you set the UART settings, network serial port settings, and operation mode, select Apply to make the settings take effect.Resetting theEthernet AdapterIf the Ethernet Adapter stops responding correctly, you can perform a reset, which disrupts the network association temporarily, but does not affect Ethernet Adapter configuration settings that have already been applied with Apply.To reset the Ethernet Adapter, under Tools, click Reset Wireless Ethernet Adapter.

Disconnecting the Ethernet Adapter 53Disconnecting the Ethernet AdapterTo disconnect the Ethernet Adapter:CAUTION: Disconnecting the Ethernet Adapter ends the network association. To avoid possible data loss, exit all networking applications on connected devices before you disconnect the Ethernet Adapter.VORSICHT: Wird die Verbindung des Ethernet-Adapters getrennt, wird damit auch die Netzwerkverbindung unterbrochen. Zur Vermeidung von eventuellen Datenverlusten müssen alle Netzwerkanwendungen auf verbundenen Geräten beendet werden, bevor die Verbindung des Ethernet-Adapters getrennt wird.1Unplug the Ethernet Adapter Ethernet cable from the hub or other device.2Unplug the Ethernet Adapter power cord.Symptom Solution(s)You are running Windows NT. After you connect the Ethernet Adapter, your computer cannot obtain a valid IP address.The Ethernet Adapter 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 Ethernet Adapter is unable to associate with the network to obtain the IP address. To work around this, set a static IP address on your computer. Then set the Ethernet Adapter configuration to match the network. When the Ethernet Adapter is able to associate, reset your computer to obtain its IP address from the DHCP server. If the Ethernet Adapter 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.Access to the Ethernet Adapter through Ethernet is blocked because of incorrect settings in the Access Control List.Restore the Ethernet Adapter to factory default settings (see “Restoring the Ethernet Adapter to Factory Defaults” on page 45). The factory default setting for the Access Control List is disabled. After the factory default settings are restored, the Ethernet Adapter can be accessed through Ethernet again.Table 15 Troubleshooting (continued)
