11. Introduction 1.1. Overview The SMC2585W-G is a versatile device that can be configured to be in one of the 3 opera-tional modes—Bridge Repeater, AP Repeater, Dual AP—for various wireless bridging ap-plications. With the convenient Web-based user interface, a network administrator can easily and clearly manage the SMC2585W-G. 1.2. Features z IEEE 802.11b/g Compliant  Operational modes. z Bridge Repeater. In this mode, both WLAN interfaces are configured as LAN-to-LAN bridge interfaces. A bridge repeater forwards packets between two wireless LAN-to-LAN bridges. z Static AP Repeater. In this mode, one WLAN interface is configured as an AP interface, and the other is configured as a LAN-to-LAN bridge interface. z Dynamic AP Repeater. In this mode, one WLAN interface is configured as an AP interface, and the other is configured as an AP client-based dynamic bridge Interface. z Dual AP. In this mode, both WLAN interfaces are configured as AP interfaces. The dual AP can handle twice the number of wireless clients than a normal AP.  64-bit and 128-bit WEP (Wired Equivalent Privacy). For wireless data encryp-tion.  IEEE 802.1x/RADIUS. When the SMC2585W-G is in Access Point mode, it can be configured to authenticate wireless users and distribute encryption keys dynami-cally by IEEE 802.1x Port-Based Network Access Control and RADIUS (Remote Authentication Dial-In User Service).  WPA (Wi-Fi Protected Access). The SMC2585W-G supports the new WPA standard. Both WPA-PSK (Pre-Shared Key) mode and full WPA mode are sup-ported. WPA is composed of TKIP (Temporal Key Integrity Protocol) and IEEE 802.1x and serves as a successor to WEP for better WLAN security.  Enabling/disabling SSID broadcasts. When the SMC2585W-G is in AP mode, the administrator can enable or disable the SSID broadcasts functionality for secu-rity reasons. When the SSID broadcasts functionality is disabled, an STA cannot associate with the AP with an ANY network name (SSID, Service Set ID); the cor-rect SSID has to be specified on the STA.  MAC-address-based access control. When the SMC2585W-G is in AP mode, it can be configured to block unauthorized STAs based on MAC (Media Access Control) addresses. The ACL (Access Control List) can also be downloaded from a
2TFTP server.  Transmit power control. Transmit power of the SMC2585W-G can be adjusted to control the area of coverage.  Wireless client isolation. When the SMC2585W-G is in AP mode, wire-less-to-wireless traffic between STAs can be blocked so that the STAs cannot see each other. This capability can be used in hotspots applications to prevent wireless hackers from attacking other wireless users’ computers.  Link integrity. When the SMC2585W-G is in AP mode and the Ethernet LAN in-terface is detected to be disconnected from the wired network, all currently associ-ated wireless clients are disassociated by the SMC2585W-G and no wireless client can associate with it thereafter.  Associated wireless clients status. Showing the status of all wireless clients that are associated with the SMC2585W-G.  Detachable antenna. The SMC2585W-G antenna can be replaced with SMC high-gain antennas for long operating range. z DHCP client. The SMC2585W-G can automatically obtain an IP address from a DHCP server. z DHCP server. The SMC2585W-G can automatically assign IP addresses to computers or other devices by DHCP (Dynamic Host Configuration Protocol).  Static DHCP mappings. The administrator can specify static IP address to MAC address mappings so that the specified IP addresses are always assigned to the hosts with the specified MAC addresses.  Current DHCP mappings. Showing which IP address is assigned to which host identified by a MAC address. z Packet Filtering. The SMC2585W-G provides Layer 2, Layer 3, and Layer 4 filtering capabilities. z Firmware Tools  Firmware upgrade. The firmware of the SMC2585W-G can be upgraded via the following methods:  TFTP-based. Upgrading firmware by TFTP (Trivial File Transfer Protocol).  HTTP-based. Upgrading firmware by HTTP (HyperText Transfer Protocol).  Configuration backup. The configuration settings of the SMC2585W-G can be backed up to a file via TFTP or HTTP.  Configuration reset. Resetting the configuration settings to factory-default values. z Management  Web-based management for configuring and monitoring SMC2585W-G via a Web-Browser.
3 Single administrator logon. Only one administrator can log on to the SMC2585W-G for management purposes at a time.  SNMP. SNMP (Simple Network Management Protocol) MIB I, MIB II, IEEE 802.1d, and Private Enterprise MIB are supported.  UPnP. The SMC2585W-G responds to UPnP discovery messages so that a Win-dows XP user can locate the SMC2585W-G in My Network Places and use a Web browser to configure it.  Telnet. The SMC2585W-G can be managed by Telnet.  System log. For system operational status monitoring.  Local log. System events are logged to the on-board RAM of the SMC2585W-G and can be viewed using a Web browser.  Remote log by SNMP trap. Systems events are sent in the form of SNMP traps to a remote SNMP management server.  Remote log by BSD Syslog. Systems events are sent in the form of BSD Syslog (RFC3164) to a remote Syslog server. z Power over Ethernet. Supplying power to an SMC2585W-G over an Ethernet cable using optional SMCPWR-INJ3 Power Injector (IEEE 802.3af compliant). This feature facilitates large-scale wireless LAN deployment. z Hardware Watchdog Timer. If the firmware gets stuck in an invalid state, the hardware watchdog timer will detect this situation and restart the SMC2585W-G. This way, the SMC2585W-G can provide continuous services.
41.3. LED Definitions There are several LED indicators on the SMC2585W-G. They are defined as follows: z ALV: Alive. Blinks when the SMC2585W-G is working normally. z RF1: IEEE 802.11b/g interface activity z RF2: IEEE 802.11b/g interface activity z LAN: Ethernet LAN interface activity z PWR: Power

7 Fig. 3. Mounting the SMC2585W-G on a wall. 2.3. Preparing for Configuration To configure a SMC2585W-G, a managing computer with a Web browser is needed. For first-time configuration of a SMC2585W-G, an Ethernet network interface card (NIC) should have been installed in the managing computer. For maintenance-configuration of a deployed SMC2585W-G, either a wireless computer or a wired computer can be employed as the managing computer. NOTE: If you are using the browser, Opera, to configure an SMC2585W-G, click the menu item File, click Preferences... click File types, and edit the MIME type, text/html, to add a file extension “.sht” so that Opera can work properly with the Web management pages of the SMC2585W-G. Since the configuration/management protocol is HTTP-based, you have to make sure that the IP address of the managing computer and the IP address of the managed SMC2585W-G are in the same IP subnet (Default IP address is set to DHCP client, it will default to 192.168.2.50 if there is no DHCP server present.) 2.3.1. Connecting the Managing Computer and the SMC2585W-G To connect the managing computer and the SMC2585W-G for first-time configuration, you have two choices as illustrated in Fig. 4.
8 Managing Computer Normal Ethernet cable Managed SMC2586W-G Normal Ethernet cable Ethernet Hub/SwitchCross-overEthernet cable Fig. 4. Connecting a managing computer and an SMC2585W-G via Ethernet. You can use either a cross-over Ethernet cable (included in the package) or a switch/hub with 2 straight-through Ethernet cables. NOTE: One connector of the Ethernet cable must be plugged into the LAN Ethernet port of the SMC2585W-G for configuration. 2.3.2. Changing the TCP/IP Settings of the Managing Computer Use the Windows Network Control Panel Applet to change the TCP/IP settings of the managing computer, so that the IP address of the computer and the IP address of the SMC2585W-G are in the same IP subnet. Set the IP address of the computer to 192.168.2.xxx (Default IP address is set to DHCP client, it will default to 192.168.2.50 if there is no DHCP server present.) TIP: You can use SMC2585W-G Scan Utility on the CD-ROM to scan for all the SMC2585W-Gs on the network. Double-click a scanned SMC2585W-G to launch the Web browser to manage the SMC2585W-G. Note that this utility does not discover the SMC2682W. NOTE: On Windows 2000/XP, SMC2585W-G Scan Utility can only be run by a user with administrator privilege. NOTE: For some versions of Windows, the computer needs to be restarted for the changes of TCP/IP settings to take effect. 2.4. Configuring the SMC2585W-G The SMC2585W-G is DHCP client enabled by default. After the IP addressing is configured, launch a Web browser on the managing computer. Then, go to “http://192.168.2.50” to log on to the SMC2585W-G for Web-based management.
9TIP: For maintenance configuration of an SMC2585W-G, the SMC2585W-G can be reached by its host name using a Web browser. For example, if the SMC2585W-G is named “AP”, you can use the URL “http://AP” to access the Web-based management interface of the SMC2585W-G. 2.4.1. Entering the User Name and Password To log onto the Web based management interface, you will be prompted to enter the user name and password. For first-time configuration, use the default user name “admin” and default password “smcadmin”, respectively. And then, click Log On. Fig. 5. Entering the user name and password. NOTE: It is strongly recommended that the password be changed to other value for security reasons. On the start page, click the General, Password link to change the value of the password (see Section 3.3.1 for more information). TIP: Since the Status page shows the current settings and status of the SMC2585W-G, it can be saved or printed within the Web browser for future reference. Fig. 6. The Status page.
102.4.2. Step 1: Selecting an Operational Mode Fig. 7. Operational modes settings. The SMC2585W-G supports 3 operational modes for meeting various wireless connectivity requirements:  Bridge Repeater. In this mode, both WLAN interfaces are configured as LAN-to-LAN bridge interfaces. A bridge repeater forwards packets between two wireless LAN-to-LAN bridges.  Static AP Repeater. In this mode, one WLAN interface is configured as an AP interface, and the other is configured as a LAN-to-LAN bridge interface.  Dynamic AP Repeater. In this mode, one WLAN interface is configured as an AP interface, and the other is configured as an AP client-based dynamic bridge Interface.  Dual AP. In this mode, both WLAN interfaces are configured as AP interfaces. The dual AP can handle twice the number of wireless clients than a normal AP. In any mode, the SMC2585W-G forwards packets between its Ethernet interface and wireless interface for wired hosts on the Ethernet side and wireless host(s) on the wire-less side. There is 1 type of wireless link to bridge between other SMC2585W-G or SMC2586W-G, and SMC2582W-B bridges.  WDS. This type of wireless link is specified in the IEEE 802.11 standard for com-munication between two IEEE 802.11 APs. Wireless packets transmitted along the WDS link comply with the IEEE 802.11 WDS (Wireless Distribution System) format at the link layer.
112.4.3. Step 2: Configuring TCP/IP Settings Fig. 8. TCP/IP settings. Go to the TCP/IP Addressing section to configure IP address settings. The IP address can be manually set or automatically assigned by a DHCP server on the LAN (Default: DHCP client enabled). If you are manually setting the IP address, Subnet mask, and Default gateway settings, set them appropriately, so that they comply with your LAN environment. In addition, you can specify the Host name and Domain (DNS suffix) of the SMC2585W-G. When you are finished, click Save at the bottom of this page, and then you are brought back to the start page. Step 3: Configuring IEEE 802.11 Settings Fig. 9. IEEE 802.11g communication settings. Go to the IEEE 802.11, Communication section to configure IEEE 802.11g-related commu-nication settings, including Channel number and Network name (SSID). The number of available RF channels depends on local regulations.
12NOTE: The Regulatory domain setting of the SMC2585W-G sold in the U.S. and Canada in not configurable. It’s set to FCC by default. As a result, only channels from 1 to 11 are available. NOTE: For two SMC2585W-Gs or one wireless client computer and one SMC2585W-G to establish a wireless link, both devices must be configured with the same channel number and SSID. Fig. 10. Wireless Distribution System settings. To enable a WDS link: 1. Specify the MAC address of the AP or bridge at the other end of the WDS link. 2. Select the corresponding Enabled check box. For example, assume you want two SMC2585W-Gs with MAC addresses 00-02-65-01-62-C5 and 00-02-65-01-62-C6 to establish a WDS link between them. On SMC2585W-G 00-02-65-01-62-C5, set the peer MAC address of port 1 to 00-02-65-01-62-C6 and on SMC2585W-G 00-02-65-01-62-C6, set the peer MAC address of port 1 to 00-02-65-01-C5. 3. When you are finished, click Save at the bottom of this page. You will be brought back to the Status page. TIP: Plan your wireless network and draw a diagram, so that you know how the SMC2585W-G is connected to other peer APs or wireless bridges by WDS.
13 Fig. 11. Sample wireless bridge network topology. WARNING: Do not let your network topology consist of wireless bridges, Ethernet switches, Ethernet links, and WDS links that form a loop. If there are any loops that exist, packets will circle around the loops and network performance will be seriously degraded. Fig. 12. Network topology containing a loop.
142.4.4. Step 4: Reviewing and Applying Settings Fig. 13. Settings changes are highlighted in red. On the start page, you can review all the settings you have made. Changes are highlighted in red. If they are OK, click Restart for the new settings to take effect. NOTE: It takes about 7 seconds for the SMC2585W-G to complete its restart process. NOTE: If you decide not to change settings of the SMC2585W-G, be sure to log off by click-ing the Log Off button on the left menu. This way another administrator can log on to the device to do configuration and management. If you do not click the Log Off button or have not interacted with the Web management interface for a period of time specified by the Web admin idle timeout setting (5 minutes by default), you’ll be automatically logged off by the device. 2.5. Deploying the SMC2585W-G After the settings have been configured, deploy the SMC2585W-G to the field application environment. Connect the SMC2585W-G to an Ethernet LAN through an Ethernet switch/hub. If external high-gain directional antennas are needed, it may be difficult to align the antennas. Here are some suggestions for antenna alignment. To adjust the alignments of a pair of SMC high-gain antennas: 1. Connect each SMC2585W-G to a computer via Ethernet. 2. Configure the date rate of each SMC2585W-G to the lowest value, 1Mbps.
153. Fix the alignment of the antenna on one side. 4. Adjust the alignment of the antenna on other side by using response time information obtained from PINGing (run PING.exe) the “fixed-side” computer. 5. Fine-tune the alignment of the antenna until you get the best response time. 6. Increase the data rate of each SMC2585W-G simultaneously until an optimal workable data rate is reached. You may not be able to use the highest data rate, 54Mbps, be-cause of the distance and the gain of the antennas. Fig. 14 illustrates the idea. Fig. 14. Adjusting alignments of external directional antennas.

At the bottom of each status page shows read-only information, there are two but-tons—Home and Refresh. Clicking Home brings you back to the start page. Clicking Re-fresh updates the shown status information. 3.2. Viewing Status 3.2.1. Associated Wireless Clients Fig. 19. Status of associated wireless clients. On this page, the status information of each associated client, including its MAC address, IP address, user name, number of bytes it has send, number of bytes it has received, and the time of its last activity, is shown.
193.2.2. Current DHCP Mappings Fig. 20. Current DHCP mappings. On this page, all the current static or dynamic DHCP mappings are shown. A DHCP map-ping is a correspondence relationship between an IP address assigned by the DHCP server and a computer or device that obtains the IP address. A computer or device that acts as a DHCP client is identified by its MAC address. A static mapping indicates that the DHCP client always obtains the specified IP address from the DHCP server. You can set static DHCP mappings in the Static DHCP Mappings section of the DHCP Server configuration page (see Section 3.4.2). A dynamic mapping indicates that the DHCP server chooses an IP address from the IP address pool from the DHCP Server configuration page. 3.2.3. System Log Fig. 21. System log. System events are recorded in the memory of the SMC2585W-G. The logged information is useful for troubleshooting purposes. The system events are divided into several categories, and you can select which categories of events to log. See Section 3.6.2.3 for more informa-tion.
203.3. General Operations 3.3.1. Selecting an Operational Mode Fig. 22. Operational modes settings. The SMC2585W-G supports 4 operational modes for meeting various wireless connectivity requirements:  Bridge Repeater. In this mode, both WLAN interfaces are configured as LAN-to-LAN bridge interfaces. A bridge repeater forwards packets between two wireless LAN-to-LAN bridges.  Static AP Repeater. In this mode, one WLAN interface is configured as an AP interface, and the other is configured as a LAN-to-LAN bridge interface.  Dynamic AP Repeater. In this mode, one WLAN interface is configured as an AP interface, and the other is configured as an AP client-based dynamic bridge Interface.  Dual AP. In this mode, both WLAN interfaces are configured as AP interfaces. The dual AP can handle twice the number of wireless clients than a normal AP. In any mode, the SMC2585W-G forwards packets between its Ethernet interface and wire-less interface for wired hosts on the Ethernet side and wireless host(s) on the wireless side. There are 2 types of wireless links between two SMC2585W-Gs or between an
21SMC2585W-G and another wireless device.  STA-AP. This type of wireless link is specified in the IEEE 802.11 standard for communication between an IEEE 802.11 Station (STA) and an IEEE 802.11 Ac-cess Point (AP). An STA is usually a client computer (PC or PDA) with a WLAN network interface card (NIC).  WDS. This type of wireless link is specified in the IEEE 802.11 standard for com-munication between two IEEE 802.11 APs. Wireless packets transmitted along the WDS link comply with the IEEE 802.11 WDS (Wireless Distribution System) format at the link layer. The relationships among the operational modes and the wireless link types are shown in the following table: 3.3.2. Changing Password Fig. 23. Password. On this page, you can change the user name and password for the rights to modify the con-figuration of the SMC2585W-G. The new password must be typed twice for confirmation. 3.3.3. Managing Firmware Fig. 24. Firmware management protocol setting. Firmware management operations for the SMC2585W-G include firmware upgrade, con-figuration backup, configuration restore, and configuration reset. Firmware upgrade, con-figuration backup, and configuration restore can be achieved via HTTP or TFTP. The HTTP-based way is suggested because it’s more user-friendly. However, due to different behavior of different Web browser types and versions, HTTP-based firmware management operations may not work properly with some Web browsers. If you cannot successfully per-form HTTP-based firmware management operations with your Web browser, try the TFTP-based method. 3.3.3.1. Upgrading Firmware by HTTP Fig. 25. Firmware upgrade by HTTP.
22To upgrade firmware of the SMC2585W-G by HTTP: 1. Click Browse and then select a correct firmware .bin file. The firmware file path will be shown in the Firmware file name text box. 2. Click Upgrade to begin the upgrade process. 3.3.3.2. Backing up and Restoring Configuration Settings by HTTP Fig. 26. Firmware backup by HTTP. To back up configuration of the SMC2585W-G by HTTP: 1. Click Back Up. 2. You’ll be prompted to open or save the configuration file. Click Save. 3. The configuration file is named SMC2585W-G_Backup.hex. Don’t change the configu-ration file name in the Save As dialog box. Select a folder in which the configuration file is to be stored. And then, click Save. NOTE: The procedure may be a little different with different Web browsers. Fig. 27. Configuration restore by HTTP. To restore configuration of the SMC2585W-G by HTTP: 1. Click Browse and then select a correct configuration .hex file. You have to make sure the file name is the SMC2585W-G_Backup.hex. The file path will be shown in the Con-figuration file name text box. 2. Click Restore to upload the configuration file to the SMC2585W-G. 3.3.3.3. Upgrading Firmware by TFTP Fig. 28. TFTP server settings. When use TFTP as the firmware management protocol, you can configure settings for the SMC2585W-G’s TFTP client to communicate with a TFTP server. If the TFTP client does not get a response from the TFTP server within a period specified by the Timeout setting, it will
23resend the previous request. The Max number of retries setting specifies the maximal number of resend before the TFTP client stops communicating with the TFTP server. The SMC2585W-G Installation CD includes a TFTP server program (TftpSrvr.exe) for firm-ware upgrade. Run this program on the computer which serves as a TFTP server. Fig. 29. Firmware upgrade by TFTP. To upgrade firmware of the SMC2585W-G by TFTP: 1. Use a computer that will serve as a TFTP server and as a managing computer to trig-ger the upgrade process. 2. Connect the computer and one of the LAN Ethernet switch port with a standard Ethernet cable. 3. Configure the IP address of the computer so that the SMC2585W-G and the computer are in the same IP subnet. 4. Run the TFTP Server utility on the computer. Specify the folder in which the firmware files reside. 5. On the computer, run a Web browser and click the General, Firmware Tools hyperlink. 6. Choose TFTP as the Firmware management protocol. 7. Specify the IP address of the computer, which acts as a TFTP server. If you don’t know the IP address of the computer, open a Command Prompt, and type IpConfig, then press the Enter key. 8. Trigger the firmware upgrade process by clicking Upgrade.
24 Fig. 30. TFTP Server. NOTE: After the dialog box of the TFTP server program appears, be sure to specify the folder which the downloaded firmware files reside. NOTE: Make sure the Accept read requests check box of TFTP Server is selected. NOTE: The LAN IP address of the SMC2585W-G and the IP address of the TFTP server must be in the same IP subnet for TFTP to work. NOTE: It is highly recommended that the TFTP server and the to-be-upgraded SMC2585W-G be connected by Ethernet and on the same LAN. NOTE: After the firmware is upgraded, be sure to delete the contents of the Web browser cache, so that the Web management pages can be shown correctly. NOTE: A failed upgrade may corrupt the firmware and cause the SMC2585W-G to not be restarted. When this occurs, call for technical support. TIP: If you want to remotely upgrade the firmware of a deployed SMC2585W-G from the Internet, adjust the Timeout and Max no. of retries settings of TFTP Server for remote TFTP upgrade to succeed. 3.3.3.4. Backing up and Restoring Configuration Settings by TFTP Fig. 31. Configuration backup/restore. To back up configuration of the SMC2585W-G by TFTP:
251. Use a computer that will serve as a TFTP server and as a managing computer to trig-ger the backup process. 2. Connect the computer and one of the LAN Ethernet switch port with a standard Ethernet cable. 3. Configure the IP address of the computer so that the computer and the SMC2585W-G are in the same IP subnet. 4. Run the TFTP Server utility on the computer. Select the Accept write requests check box, and specify the folder to which the configuration settings of the SMC2585W-G will be saved. 5. On the computer, run a Web browser and click the General, Firmware Tools hyperlink. 6. Choose TFTP as the Firmware management protocol. 7. Within the Configuration Backup/Restore section, specify the IP address of the com-puter, which acts as a TFTP server. If you don’t know the IP address of the computer, open a Command Prompt, and type IpConfig, then press the Enter key. 8. Trigger the backup process by clicking Back Up. The backup file is named SMC2585W-G_Backup NOTE: Remember to select the Accept write requests check box of TFTP Server. To restore configuration of the SMC2585W-G by TFTP: 1. Use a computer that will serve as a TFTP server and as a managing computer to trig-ger the restoring process. 2. Connect the computer and one of the LAN Ethernet switch port with a standard Ethernet cable. 3. Configure the IP address of the computer so that the computer and the SMC2585W-G are in the same IP subnet. 4. Run the TFTP Server utility on the computer. Specify the folder in which the configura-tion backup file resides. A configuration backup file is named SMC2585W-G_Backup.hex. 5. On the computer, run a Web browser and click the General, Firmware Tools hyperlink. 6. Choose TFTP as the Firmware management protocol. 7. Within the Configuration Backup/Restore section, specify the IP address of the com-puter, which acts as a TFTP server. If you don’t know the IP address of the computer, open a Command Prompt, and type IpConfig, then press the Enter key. 8. Trigger the restoring process by clicking Restore. The SMC2585W-G will then download the configuration backup file from the TFTP server.
26 NOTE: Make sure the file is a valid configuration backup file for the SMC2585W-G. TIP: If you want to remotely back up or restore configuration from the Internet, adjust the Timeout and Max no. of retries settings of TFTP Server for remote TFTP configuration backup/restore to succeed. 3.3.3.5. Resetting Configuration to Factory Defaults Fig. 32. Configuration reset. Click on the Reset button to reset the device configuration to factory defaults. 3.4. Configuring TCP/IP Related Settings 3.4.1. Addressing Fig. 33. TCP/IP settings. The IP address of the SMC2585W-G can be manually set (Set Manually) or automatically assigned by a DHCP server on the LAN (Obtain from a DHCP Server – enabled by de-fault). If you are manually setting the IP address, Subnet mask, and Default gateway set-tings, set them appropriately, so that they comply with your LAN environment. In addition, you can specify the Host name and Domain (DNS suffix) of the SMC2585W-G.
273.4.2. DHCP Server 3.4.2.1. Basic Fig. 34. Basic DHCP server settings. The SMC2585W-G can automatically assign IP addresses to client computers by DHCP. In this section of the management page, you can specify the Default gateway, Subnet mask, Primary DNS server, and Secondary DNS server settings that will be sent to a client at its request. Additionally, you can specify the first IP address that will be assigned to the clients and the number of allocateable IP addresses. NOTE: There should be only one DHCP server on the LAN; otherwise, DHCP would not work properly. If there is a DHCP server on the LAN already, disable the DHCP server func-tionality of the SMC2585W-G. NOTE: By default the DHCP server function is disabled. 3.4.2.2. Static DHCP Mappings Fig. 35. Static DHCP mappings. IP addresses of servers are often static so that clients could always locate the servers by the static IP addresses. By Static DHCP Mappings, you can ensure that a host will get the same IP address when it requests one from the DHCP server. Therefore, instead of config-uring the IP address of an intranet server manually, you can configure the server to obtain
28an IP address by DHCP and it is always assigned the same IP address. To always assign a static IP address to a specific DHCP client: 1. Specify the MAC address of the DHCP client and the IP address to be assigned to it. Then, give a description of this mapping. 2. Select the corresponding Enabled check box. 3.5. Configuring IEEE 802.11b/g-Related Settings 3.5.1. Communication 3.5.1.1. Basic Basic IEEE 802.11b/g-related communication settings include AP functionality, Regulatory domain, Channel number, Network name (SSID), Data rate, and Transmit power. Fig. 36. Basic IEEE 802.11b/g communication settings. For specific needs such as configuring the SMC2585W-G as a wireless LAN-to-LAN bridge, the AP functionality can be disabled, so that no wireless client can associate with the SMC2585W-G. Since the IEEE 802.11g-based SMC2585W-G is also IEEE 802.11b compatible, you can configure the Policy setting to meet your backwards compatibility needs. If the SMC2585W-G is used in an environment in which all wireless clients are IEEE 802.11b-based, set Policy to b only. If all the wireless clients are IEEE 802.11g-based, set Policy to g only. For maximal flexibility, set Policy to Mixed, in which mode, the SMC2585W-G supports both IEEE 802.11b- and IEEE 802.11g-based wireless clients. The number of available RF channels depends on local regulations; therefore you have to choose an appropriate regulatory domain to comply with local regulations. The SSID of a wireless client computer and the SSID of the SMC2585W-G must be identical for them to communicate with each other. NOTE: The Regulatory domain setting of the SMC2585W-G sold in the U.S. and Canada in not configurable. It’s set to FCC by default. As a result, only channels from 1 to 11 are available. If there is RF interference, you may want to reduce the Data rate for more reliable wireless transmission. In most cases, leave the setting to Auto.
29The transmit power of the RF module of the SMC2585W-G can be adjusted so that the RF coverage of the SMC2585W-G can be changed. 3.5.1.2. Link Integrity Fig. 37. Link integrity settings. When the SMC2585W-G is in AP mode and the Ethernet LAN interface is detected to be disconnected from the wired network, all currently associated wireless clients are disassoci-ated by the SMC2585W-G and no wireless client can associate with the SMC2585W-G. The detection mechanism is based on pinging the IP address specified in Reference host. 3.5.1.3. Wireless Distribution System LAN AP 2Notebook Computer AP 1WDS Fig. 38. Wireless Distribution System. Traditionally, access points are connected by Ethernet. By IEEE 802.11 Wireless Distribution System (WDS), APs can communicate with one another wirelessly. For example, in Fig. 38, AP 2 acts as an access point for the notebook computers and it forwards packets sent from the notebook computers to AP 1 through WDS. Then, AP 1 forwards the packets to the Ethernet LAN. Packets destined for the notebook computers follow a reverse path from the Ethernet LAN through the APs to the notebook computers. In this way, AP 2 plays a role of “AP repeater”.
30 LAN Segment 2 LAN Segment 1 Bridge 1 WDS LinkBridge 2 Fig. 39. LAN-to-LAN bridging. By WDS, two or more LAN segments can be connected wirelessly. As illustrated in Fig. 39, a pair of wireless LAN-to-LAN bridges is used to connect two LAN segments. Since the SMC2585W-G is WDS-enabled, it can be used as a wireless bridge even when it is in AP mode. NOTE: An SMC2585W-G can have up to 6 WDS links to other APs or wireless bridges per radio. Fig. 40. Wireless Distribution System settings. To enable a WDS link: 3. Specify the MAC address of the AP or bridge at the other end of the WDS link. 4. Select the corresponding Enabled check box. For example, assume you want two SMC2585W-Gs with MAC addresses 00-02-65-01-62-C5 and 00-02-65-01-62-C6 to establish a WDS link between them. On SMC2585W-G 00-02-65-01-62-C5, set the peer MAC address of port 1 to 00-02-65-01-62-C6 and on SMC2585W-G 00-02-65-01-62-C6, set the peer MAC address of port 1 to 00-02-65-01-C5. TIP: Plan your wireless network and draw a diagram, so that you know how an AP is con-nected to other peer APs or wireless bridges by WDS. TIP: Plan your wireless network and draw a diagram, so that you know how a bridge is con-nected to other peer bridges by WDS. See the following figure for an example net-work-planning diagram.
31 Fig. 41. Sample wireless bridge network topology. WARNING: Do not let your network topology consist of wireless bridges, Ethernet switches, Ethernet links, and WDS links that form a loop. If there are any loops that exist, packets will circle around the loops and network performance will be seriously degraded. Fig. 42. Network topology containing a loop. 3.5.2. Security IEEE 802.11b/g security settings include SSID broadcasts, Security mode, IEEE 802.11 Authentication algorithm, WEP keys, MAC-Address-Based Access Control.
323.5.2.1. Basic Fig. 43. Basic IEEE 802.11g security settings. For security reasons, it’s highly recommended that the security mode be set to options other than Open System. When the security mode is set to Open System, no authentication and data encryption will be performed. Additionally, you can disable the SSID broadcasts func-tionality so that a wireless client with an “ANY” SSID cannot associate with the SMC2585W-G. Wireless Client Isolation is a feature for the SMC2585W-G in AP mode to block wire-less-to-wireless traffic between STAs so that the STAs cannot see each other. This feature is useful for WLANs deployed in public places. This way, hackers have no chance to attack other wireless users in a hotspot. When the Wireless client isolation setting is set to This AP Only, wireless clients (STAs) associated to this SMC2585W-G, which acts as an AP, cannot see each other, and wire-less-to-wireless traffic between the STAs is blocked. When the setting is set to All APs in This Subnet, traffic among wireless users of different SMC2585W-Gs in the same IP subnet is blocked. The behaviors are illustrated in the following figures. AP 1 AP 2STA 1 STA 2 STA 3Wireless LinkEthernet LinkSwitchWCI:This AP Only WCI:This AP Only Fig. 44. Behavior of the “This AP Only” wireless client isolation option.
33AP 1 AP 2STA 1 STA 2 STA 3Wireless LinkEthernet LinkSwitchWCI:All APs in ThisSubnetWCI:All APs in ThisSubnet Fig. 45. Behavior of the “All APs on This Subnet” wireless client isolation option. As illustrated in Fig. 44 when AP 1 and AP 2 are using the “This AP Only” option, wireless traffic between STA 1 and STA 2 is blocked by AP 1, while wireless traffic between STA 2 and STA 3, which are associated with different APs, is still allowed. If the “All APs in This Subnet” option is used as shown in Fig. 45, AP 1 and AP 2 communicates with each other via an inter-AP protocol to share their STA association information to block wireless traffic among all the STAs. There are up to 7 security modes: z Open System. No authentication, no data encryption. z Static WEP. WEP (Wired Equivalent Privacy) keys must be manually configured. z Static TKIP (WPA-PSK). Only TKIP (Temporal Key Integrity Protocol) mechanism of WPA (Wi-Fi Protected Access) is enabled. In this mode, you have to specify the Pre-shared key, which will be used by the TKIP engine as a master key to generate keys that actually encrypt outgoing packets and decrypt incoming packets. NOTE: The number of characters of the Pre-shared key setting must be at least 8 and can be up to 63. z IEEE 802.1x EAP without Encryption (EAP-MD5). The IEEE 802.1x functionality is enabled and the user-name/password-based EAP-MD5 authentication is used. No data encryption. z IEEE 802.1x EAP with Static WEP (EAP-MD5). The IEEE 802.1x functionality is en-abled and the user-name/password-based EAP-MD5 authentication is used. Data en-cryption is achieved by static WEP. z IEEE 802.1x EAP with Dynamic WEP (EAP-TLS, EAP-TTLS, PEAP). The IEEE 802.1x functionality is enabled and dynamic WEP key distribution authentication (EAP-TLS, EAP-TTLS, or PEAP) is used. Data encryption is achieved by dynamic WEP. z IEEE 802.1x EAP with Dynamic TKIP (WPA). This is a full WPA mode, in which both
34the TKIP and IEEE 802.1x dynamic key exchange mechanisms are enabled. The SMC2585W-G is highly secured in this mode. In the above security modes, a back-end RADIUS (Remote Authentication Dial-In User Ser-vice) server is needed if IEEE 802.1x functionality is enabled. According to the IEEE 802.11 standard, WEP can be used for authentication and data en-cryption. Normally, Shared Key authentication is used if WEP data encryption is enabled. In rare cases, Open System authentication may be used when WEP data encryption is enabled. The Authentication algorithm setting is provided for better compatibility with wireless client computers with various WLAN network adapters. There are three options available, including Open System, Shared Key, and Auto. When WEP is enabled by a security mode, the Key length can be specified to be 64 Bits or 128 Bits. The Selected key setting specifies the key to be used as a send-key for encrypt-ing traffic from the local device side to the remote device side. All 4 WEP keys are used as receive-keys to decrypt traffic from the remote device side to the local device side. NOTE: Each field of a WEP key setting is a hex-decimal number from 0-9, A-F. For exam-ple, when the security mode is Static WEP and the key length is 64 Bits, you could set Key 1 to “00012E3ADF”. 3.5.2.2. MAC-Address-Based Access Control Fig. 46. MAC-address-based access control settings. With MAC-Address-Based Access Control, you can specify the wireless clients that are permitted or not permitted to associate with the SMC2585W-G. When the table type is set to inclusive, entries in the table are permitted to associate with the SMC2585W-G. When the table type is set to exclusive, entries in the table are not permitted to associate with the SMC2585W-G. NOTE: MAC-address-based access control is only available when the SMC2585W-G is in AP mode. To deny wireless clients’ access to the wireless network: 1. Select Enabled from the Functionality drop-down list. 2. Set the Access control type to exclusive. 3. Specify the MAC address of a wireless client to be denied access, and then click Add. 4. Repeat Step 3 for each other wireless client.
35To grant wireless clients’ access to the wireless network: 1. Select Enabled from the Functionality drop-down list. 2. Set the Access control type to inclusive. 3. Specify the MAC address of a wireless client to allow access, and then click Add. 4. Repeat Step 3 for each other wireless client. To delete an entry in the access control table: z Click Delete next to the entry. NOTE: The size of the access control table is 64. Fig. 47. MAC ACL download settings. Instead of manually entering MAC addresses to the access control table one by one, you can prepare a text file that contains all the MAC addresses and put it on a TFTP server, and then download the MAC ACL (Access Control List) file from the TFTP server to the SMC2585W-G. Fig. 48 shows the contents of a sample ACL file. Fig. 48. Sample MAC ACL file. To download a MAC ACL file from a TFTP server: 1.

363.5.3. IEEE 802.1x/RADIUS IEEE 802.1x Port-Based Network Access Control is a new standard for solving some secu-rity issues associated with IEEE 802.11, such as lack of user-based authentication and dy-namic encryption key distribution. With IEEE 802.1x, a RADIUS (Remote Authentication Dial-In User Service) server, and a user account database, an enterprise or ISP (Internet Service Provider) can manage its mobile users’ access to its wireless LANs. Before granting access to a wireless LAN supporting IEEE 802.1x, a user has to issue his or her user name and password or digital certificate to the backend RADIUS server by EAPOL (Extensible Authentication Protocol Over LAN). The RADIUS server can record accounting information such as when a user logs on to the wireless LAN and logs off from the wireless LAN for monitoring or billing purposes. The IEEE 802.1x functionality of the access point is controlled by the security mode (see Section 3.5.2.1). So far, the wireless access point supports two authentication mecha-nisms—EAP-MD5 (Message Digest version 5), EAP-TLS (Transport Layer Security). If EAP-MD5 is used, the user has to give his or her user name and password for authentica-tion. If EAP-TLS is used, the wireless client computer automatically gives the user’s digital certificate that is stored in the computer hard disk or a smart card for authentication. And af-ter a successful EAP-TLS authentication, a session key is automatically generated for wire-less packets encryption between the wireless client computer and its associated wireless access point. To sum up, EAP-MD5 supports only user authentication, while EAP-TLS sup-ports user authentication as well as dynamic encryption key distribution. Fig. 49. IEEE 802.1x and RADIUS. SMC2585W-G supports IEEE 802.1x and can be configured to communicate with two RA-DIUS servers. When the primary RADIUS server fails to respond, SMC2585W-G will try to communicate with the secondary RADIUS server. You can specify the length of timeout and the number of retries before communicating with the secondary RADIUS server after failing to communicate with the primary RADIUS server. An IEEE 802.1x-capable wireless access point and its RADIUS server(s) share a secret key
37so that they can authenticate each other. In addition to its IP address, a wireless access point can identify itself by an NAS (Network Access Server) identifier. Each IEEE 802.1x-capable wireless access point must have a unique NAS identifier. Fig. 50. IEEE 802.1x/RADIUS settings. 3.6. Configuring Advanced Settings 3.6.1. Packet Filters The SMC2585W-G provides layer 2 (Ethernet Type Filters), layer 3 (IP Protocol Filters), and layer 4 (TCP/UDP Port Filters) filtering capabilities. The configuration processes for the fil-ters are similar. Functionality: whether this filtering capability is enabled or disabled. Policy for matched packets: how a matched packet is processed—discard or pass. To enable a filtering rule: select the check box to the left of the rule. 3.6.1.1. Ethernet Type Filters Fig. 51. Ethernet type filters settings. The Ethernet type filed of the MAC (Media Access Control) header of a packet incoming from the WLAN or Ethernet interface is inspected for filtering. In a rule, specify the hex-decimal Ethernet type number and give the rule a name.
383.6.1.2. IP Protocol Filters Fig. 52. IP protocol filters settings. The protocol, source address, and destination address fields of a packet incoming from the WLAN or Ethernet interface is inspected for filtering. In a rule, specify the hex-decimal pro-tocol number, source IP address range (Source IP Address AND Source Subnet Mask), and destination IP address range (Destination IP Address AND Destination Subnet Mask). A source (destination) IP address range is determined by performing an AND operation on the source (destination) IP address field and the source (destination) subnet mask field. For example, if the source IP address field is 192.168.0.1 and the source subnet mask field is 255.255.255.0, the result source IP address range is 192.168.0.0 to 192.168.0.255. 3.6.1.3. TCP/UDP Port Filters Fig. 53. TCP/UDP port filters settings. The destination port field the TCP or UDP header of a packet incoming from the WLAN or Ethernet interface is inspected for filtering. In a rule, specify the decimal Destination Port, Protocol type (TCP/UDP), and the name of the higher-level protocol (Application Name).
393.6.2. Management 3.6.2.1. Basic Fig. 54. Basic management settings. The SMC2585W-G can be managed by Telnet. This functionality can be either enabled or disabled. As the SMC2585W-G allows only one administrator to log on for management, you have to log off before another can log on. If you forget to log off or have not interacted with the Web management interface for a period specified by the Web admin idle timeout setting (default: 5 minutes), you’ll be automatically logged off by the SMC2585W-G. 3.6.2.2. UPnP Fig. 55. UPnP settings. UPnP (Universal Plug and Play) enables a Windows XP user to automatically discover pe-ripheral devices. When the UPnP functionality is enabled, you can see the SMC2585W-G in My Network Places of Windows XP. The SMC2585W-G can be given a user-friendly name that will be shown in My Network Places. Double-clicking the icon in My Network Places that refers to the SMC2585W-G will launch the Web browser for you to configure the SMC2585W-G. NOTE: Make sure you have installed the necessary Windows UPnP components on your Windows XP computer. 3.6.2.3. System Log Fig. 56. System log settings. System events can be logged to the on-board RAM of the SMC2585W-G (Local log) or sent
40in the form of SNMP trap (Remote log by SNMP trap) or BSD Syslog (Remote log by BSD Syslog) to a remote SNMP trap monitoring server or remote Syslog server, respectively. See the next subsection for more information about SNMP trap settings. Set the IP address of the Syslog server in the Syslog server IP address text box. The system events are divided into the following categories:  General: system and network connectivity status changes.  Built-in AP: wireless client association and WEP authentication status changes.  MIB II traps: Cold Start, Warm Start, Link Up, Link Down and SNMP Authentica-tion Failure. NOTE: The SNMP Authentication Failure trap is issued when using an incorrect community string to manage the SMC2585W-G via SNMP and the SNMP MIB II OID, snmpEnableAu-thenTraps, is enabled (disabled by default). 3.6.2.4. SNMP Fig. 57. SNMP settings. The SNMP (Simple Network Management Protocol) functionality can be disabled, and you can specify the name (used as a password) of the read-only and read-write community. In addition, up to 5 SNMP trap targets can be set in the SNMP Trap Table. To specify a trap target: 1. Type the IP address of the target host. 2. Type the Community for the host. 3. Select the corresponding check box next to the IP address text box.

42Appendix B: Troubleshooting Check the following first: z Make sure that the power of the SMC2585W-G is on and the Ethernet cables are con-nected firmly to the RJ-45 jacks of the SMC2585W-G. z Make sure that the LED ALV of the SMC2585W-G is blinking to indicate the SMC2585W-G is working. z Make sure the types of the Ethernet cables are correct. Recall that there are two types—straight-through and crossover. B-1: Wireless Settings Problems z The wireless client computer cannot associate with an SMC2585W-G.  Is the wireless client set in infrastructure mode?  Check the operating mode of the WLAN NIC.  Is the SSID of the WLAN NIC identical to that of the prospective SMC2585W-G?  Check the SSID setting of the WLAN NIC and of the SMC2585W-G.  Is the WEP functionality of the prospective SMC2585W-G enabled?  Make appropriate WEP settings of the client computer to match those of the SMC2585W-G.  Is the prospective SMC2585W-G within range of wireless communication?  Check the signal strength and link quality sensed by the WLAN NIC.
43B-2: TCP/IP Settings Problems Default Gateway of Client ComputerAP IEEE 802.11b/g Stage A State BCorrespondent Host Stage D Client Computer DNS Server of Client Computer Ethernet LAN Internet Fig. 58. Communication stages for a client to reach its correspondent host. For a wireless client computer to communicate with a correspondent host on the Internet by the host’s domain name (e.g. http://www.wi-fi.com), it first sends a DNS request to a DNS server on the Internet. The DNS request travels first to the AP, then the AP relays this re-quest to the default gateway of the client computer. Finally, this request is forwarded by the gateway to the DNS server on the Internet. The DNS reply issued by the DNS server is transmitted back to the client computer following a reverse path. When the client computer receives the DNS reply, it knows the IP address of the correspondent host and sends further packets to this IP address. As illustrated in Fig. 58, the communication path could be broken at some of the stages. The OS-provided network diagnostic tool, ping.exe, can be employed to find out TCP/IP-related communication problems. NOTE: If two or more NICs are installed and operating on a client computer, TCP/IP may not work properly due to incorrect entries in the routing table. Use the OS-provided com-mand-line network tool, route.exe, to add or delete entries from the routing table. Or, use Windows-provided Device Manager to disable unnecessary NICs. Solve the following problems in order: z My SMC2585W-G does not respond to ping from the client computer.  Are two or more NICs installed on the client computer?  Use Windows-provided Device Manager to disable unnecessary NICs.  Is the underlying link (Ethernet or IEEE 802.11g) established?  Make sure the Ethernet link is OK.  Make sure the wireless settings of the wireless client computer and of the
44SMC2585W-G match.  Are the IP address of the client computer and the IP address of the SMC2585W-G in the same IP subnet?  Use WinIPCfg.exe or IPConfig.exe to see the current IP address of the client computer. Make sure the IP address of the client computer and the IP ad-dress of the SMC2585W-G are in the same IP subnet.  TIP: If you forget the current IP address of the SMC2585W-G, use Wireless Router/AP Browser to get the information (see Appendix B-3). z The default gateway of the client computer does not respond to ping from the client computer.  Solve the preceding problem first.  Are the IP address of the SMC2585W-G and the IP address of the client computer in the same IP subnet?  If you cannot find any incorrect settings of the SMC2585W-G, the default gateway may be really down or there are other communication problems on the network backbone. z The DNS server(s) of the client computer do not respond to ping from the client computer.  Solve the preceding problems first.  If you cannot find any incorrect settings of the SMC2585W-G, the default gateway of the SMC2585W-G may be really down or there are other communication prob-lems on the network backbone. B-3: Other Problems z My SMC2585W-G has been set to obtain an IP address automatically by DHCP. How can I know its acquired IP address so that I can manage it using a Web browser?  Use the SMC2585W-G Scan Utility (WLBrwsr.exe), which is included in the SMC2585W-G Installation CD. This utility can discover nearby SMC2585W-Gs and show their MAC addresses and IP addresses. In addition, it can launch the Web browser on your computer. NOTE: On Windows 2000/XP, SMC2585W-G Scan Utility can only be run by a user with administrator privilege. NOTE: SMC2585W-G Scan Utility does not scan the SMC2682W.
45 Fig. 59. SMC2585W-G Configuration Utility. z My SMC2585W-G stops working and does not respond to Web management re-quests.  The firmware of the SMC2585W-G may be stuck in an incorrect state.  Unplug the power connector from the power jack, and then re-plug the con-nector to restart the SMC2585W-G.  Contact our technical support representatives to report this problem, If this happens after a failed firmware upgrade process, the firmware of the SMC2585W-G may have been corrupted.  If the SMC2585W-G still does not work after restarting, there may be hardware component failures in the SMC2585W-G.  Contact our technical support representatives for repair.
