1.3 Features

• IEEE 802.11b/g Compliant Oper

ational modes.

• Access Point. The AP enables IEEE 802.11 Stations (STAs) to

automatically associate with it via the standard IEEE 802.11 association process. In addition, the IEEE 802.11 WDS (Wireless Distribution System) technology can be used to manually establish wireless links between two APs or between an AP and a Bridge Master.

• Bridge Master. Use this mode to provide the Bridge Master functionality of the SMC2682W. The Bridge Master mode is designed to work in those net-works where SMC2682W Wireless Bridge Slaves are already installed. The Bridge Master enables Bridge Slaves to automatically associate with it. It also enables IEEE 802.11 Stations, which are on the same LAN as the Bridge Master, to automatically associate with it via the standard IEEE 802.11 asso-ciation process. In addition, the IEEE 802.11 WDS (Wireless Distribution System) technology can be used to manually establish wireless links between two Bridge Masters or between a Bridge Master and an AP.

• Bridge Slave. Use this mode to provide the Bridge Slave functionality of the SMC2682W. The Bridge Slave mode is designed to work in those networks where SMC2682W Wireless Bridge Masters are already installed.

• 64-bit and 128-bit WEP (Wired Equivalent Privacy). For wireless data encryp-tion.

• IEEE 802.1x/RADIUS. When the SMC2586W-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 SMC2586W-G supports the new WPA stan-dard. Both WPA-PSK (Pre-Shared Key) mode and full WPA mode are supported. 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 SMC2586W-G is in AP or Bridge Master mode, the administrator can enable or disable the SSID broadcasts functionality for security reasons. When the SSID broadcasts functionality is dis-abled, an STA or Bridge Slave cannot associate with the AP or Bridge Master with an ANY network name (SSID, Service Set ID); the correct SSID has to be specified on the STA or Bridge Slave.

• MAC-address-based access control. When the SMC2586W-G is in AP or Bridge Master mode, it can be configured to block unautho rized STAs or Bridge Slaves based on MAC (Media Access Control) addresses. The ACL (Access Control List) can also be downloaded from a TFTP server.

• Transmit power control. Transmit power of the SMC2586W-G can be adjusted to control the area of coverage.

• Wireless client isolation. When the SMC2586W-G is in AP or Bridge Master mode, wireless-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 pre-vent wireless hackers from attacking other wireless users’ computers. n Link integrity. When the SMC2586W-G is in AP or Bridge Master mode and the Ethernet LAN interface is detected to be disconnected from the wired network, all currently associated wireless clients (STAs and Bridge Slaves) are disassociated by the SMC2586W-G and no wireless client can associate with it thereafter. n Associated wireless clients status. Showing the status of all wire less clients (STAs and Bridge Slaves) that are associated with the SMC2586W-G.

• Detachable antenna. The SMC2586W-G antenna can be replaced with SMC high-gain antennas for long operating range.

• DHCP client. The SMC2586W-G can automatically obtain an IP

address from a DHCP server.

• DHCP server. The SMC2586W-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.

• Showing current DHCP mappings. Showing which IP address is assigned to which host identified by a MAC address.

• Packet Filtering. The SMC2586W-G provides Layer 2, Layer 3, and

Layer 4 filtering capabilities.

Fig. 3. Mounting the SMC2586W-G on a wall.

2.3 Preparing for Configuration

To configure an SMC2586W-G, a managing computer with a Web browser is needed. For first-time configuration of an SMC2586W-G, an Ethernet network interface card (NIC) should have been installed in the managing computer. For maintenance-configuration of a deployed SMC2586W-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

SMC2586W-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 SMC2586W-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 SMC2586W-G are in the same IP subnet (the default IP address of SMC2586W-G is 192.168.2.50 and the default subnet mask is

255.255.255.0.) [DHCP Client is enabled by default. It will default to

192.168.2.50 if there is no DHCP server available on the network.]

Connecting the Managing Computer and the SMC2586W-G

To connect the managing computer and the SMC2586W-G for the first-time, you have two choices as illustrated in Fig. 4

Fig. 4. Connecting a managing computer and an SMC2586W-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 SMC2586W-G for configuration.

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 SMC2586W-G are in the same IP subnet. Set the IP address of the computer to 192.168.2.xxx (the default IP address of the SMC2586W-G is 192.168.2.50) and the subnet mask to 255.255.255.0.) [DHCP Client is enabled by default. It will default to 192.168.2.50 if there is no DHCP server available on the network.]

TIP: You can use SMC2586W-G Scan Utility on the CD-ROM to scan for all the SMC2586W-Gs on the network. Double-click a scanned SMC2586W-G to launch the Web browser to manage the SMC2586W-G. Note that this utility does not discover the SMC2682W.

NOTE: On Windows 2000/XP, SMC2586W-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 SMC2586W-G

The SMC2586W-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 SMC2586W-G for Web-based management.

TIP: For maintenance configuration of an SMC2586W-G, the SMC2586W-G can be reached by its host name using a Web browser. For example, if the SMC2586W-G is named “AP”, you can use the URL “http://AP” to access the Web-based management interface of the SMC2586W-G.

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 SMC2586W-G, it can be saved or printed within the Web browser for future reference.

Fig. 6. The Status page.

Step 1: Selecting an Operational Mode

Fig. 7. Operational modes settings.

The SMC2586W-G supports 3 operational modes for meeting various wireless connectivity requirements:

• Access Point (AP). The AP mode enables IEEE 802.11 Stations (STAs) to auto-matically associate with it via the standard IEEE 802.11 association process. In addition, the IEEE 802.11 WDS (Wireless Distribution System) technology can be used to manually establish wireless links between two APs or between an AP and a Bridge Master.

• Bridge Master (BM). Use this mode to provide the Bridge Master functionality of the SMC2682W. The Bridge Master mode is designed to work in those networks where SMC2682W Wireless Bridge Slaves are already installed. The Bridge Master enables Bridge Slaves to automatically associate with it. It also enables IEEE 802.11 Stations, which are on the same LAN as the Bridge Master, to automatically associate with it via the standard IEEE 802.11 association process. In addition, the IEEE 802.11 WDS (Wireless Distribution System) technology can be used to manually establish wireless links between two Bridge Masters or between a Bridge Master and an AP.

• Bridge Slave (BS). Use this mode to provide the Bridge Slave functional ity of the SMC2682W. The Bridge Slave mode is designed to work in those networks where SMC2682W Wireless Bridge Masters are already installed. In any mode, the SMC2586W-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 SMC2586W-Gs or between an SMC2586W-G and another wireless device.

• 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.

• BM-BS. This type of wireless link is used in the SMC2682W for providing LAN-to-LAN bridging services. To establish this type of wireless link between two SMC2682W, one SMC2682W must be in Bridge Master (BM) mode and the other must be in Bridge Slave (BS) mode. The SMC2586W-G provides this type of wireless link for backward compatibility with the SMC2682W.

The relationships among the operational modes and the wireless link types are shown in the following table:

Table 1. Operational modes vs. wireless link types.

From the table, a WDS link can be establish between two APs, a BM-BS link can be estab-lished between a Bridge Master and a Bridge Slave, but no wireless link can be established between a Bridge Slave and an AP.

Select an operational mode and click Save at the bottom of this page, and then you are brought back to the start page.

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 appropri- ately, so that they comply with your LAN environment. In addition, you can specify the Host name and Domain (DNS suffix) of the SMC2586W-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.

NOTE: The Regulatory domain setting of the SMC2586W-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 SMC2586W-Gs or one wireless client computer and one SMC2586W-G to establish a wireless link, both devices must be configured with the same channel number and SSID.

If the SMC2586W-G was configured to be in AP or Bridge Master mode, and you want to use WDS to establish inter-SMC2586W-G wireless links, configure the WDS settings.

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 SMC2586W-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 SMC2586W-G 00-02-65-01-62-C5, set the peer MAC address of port 1 to 00-02-65-01-62-C6 and on SMC2586W-G 00-02-6501-62-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 SMC2586W-G is connected to other peer APs or wireless bridges by WDS.

Fig. 11. Sample wireless bridge network topology.

Fig. 12. Network topology containing a loop.

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 SMC2586W-G

to complete its restart process.

NOTE: If you decide not to change settings of the SMC2586W-G,

be sure to log off by clicking 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 SMC2586W-G

After the settings have been configured, deploy the SMC2586W-G to the field application environment. Connect the SMC2586W-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 SMC2586W-G to a computer via Ethernet.

2. Configure the date rate of each SMC2586W-G to the lowest value, 1Mbps.

3. Fix the alignment of the antenna on one side.

4. Adjust the alignment of the antenna on the other side by using response time informa-tion 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 SMC2586W-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.

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.

System Log

Fig. 22 System log.

System events are recorded in the memory of the SMC2586W-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.

3.3 General Operations

Selecting an Operational Mode

Fig. 23. Operational modes settings.

The SMC2586W-G supports 3 operational modes for meeting various wireless connectivity requirements:

In any mode, the SMC2586W-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 3 types of wireless links between two SMC2586W-Gs or between an SMC2586W-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 Access Point (AP). An STA is usually a client computer (PC or PDA) with a WLAN network interface card (NIC).

• BM-BS. This type of wireless link is propriety and was used in the legacy SMC2682W for providing LAN-to-LAN bridging services. To establish this type of wireless link between two SMC2682W, one SMC2682W must be in Bridge Master (BM) mode and the other must be in Bridge Slave (BS) mode. The SMC2586W-G provides this type of wireless link for backward compatibility with the SMC2682W.

The relationships among the operational modes and the wireless link types are shown in the following table:

In Fig. 24 packets from STA cannot reach X, and vice versa.

Changing Password

Fig. 25 Password.

On this page, you can change the user name and password for the rights to modify the con-figuration of the SMC2586W-G. The new password must be typed twice for confirmation.

Managing Firmware

Fig. 26 Firmware management protocol setting.

Firmware management operations for the SMC2586W-G include firmware upgrade, configu-ration backup, configuration restore, and configuration reset. Firmware upgrade, configura-tion 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 perform HTTP-based firmware management operations with your Web browser, try the TFTP-based method.

Upgrading Firmware by HTTP

Fig. 27 Firmware upgrade by HTTP.

To upgrade firmware of the SMC2586W-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.

Backing up and Restoring Configuration Settings by HTTP

Fig. 28 Firmware backup by HTTP.

To back up configuration of the SMC2586W-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 SMC2586W-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.
