2.3. Preparing for Configuration

For you to configure an SMC2582W-B,a managing computer with a Web browser is needed. For first-time configuration of an SMC2582W-B,an Ethernet network interface card (NIC) should have been installed in the managing computer. For maintenance-configuration of a deployed SMC2582W-B,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 SMC2582W-B,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 SMC2582W-B.

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 SMC2582W-B are in the same IP subnet (the default IP address of an AP is 192.168.2.50 and the default subnet mask is 255.255.255.0.)

2.3.1. Connecting the Managing Computer and the SMC2582W-B

To connect the Ethernet managing computer and the managed SMC2582W-B for first-time configuration, you have two choices as illustrated in Fig. 4.

Fig. 4.Connecting a managing computer and an SMC2582W-B via Ethernet.

You can us e either a cross-over Ethernet cable (included in the package) or a switch/hub with 2 normal Ethernet cables.

NOTE: One connector of the Ethernet cable must be plugged into the LAN/CONFIG Ethernet jack of the SMC2582W-B 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 SMC2582W-B are in the same IP subnet.Set the IP address of the computer to 192.168.2.xxx (the default IP address of the SMC2582W-B is 192.168.2.50) and the subnet mask to 255.255.255.0.

TIP: You can use SMC2582W-B Configuration Utility on the companion CD-ROM to scan for all the SMC2582W-Bs on the network.Double-click a scanned SMC2582W-B to launch the Web browser to manage the SMC2582W-B.Note that this utility does not discover the SMC2682W.

NOTE: On Windows 2000/XP, SMC2582W-B Configuration 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 SMC2582W-B

After the IP addressing is configured,launch a Web browser on the managing computer.Then, go to “http://192.168.2.50”to access the Start page of the SMC2582W-B’s Web-based management interface.

TIP: For maintenance configuration of an SMC2582W-B,the SMC2582W-B can be reached by its host name using a Web browser. For example, if the SMC2582W-B is named “AP”,you can use the URL “http://AP” to access the Web-based management interface of the SMC2582W-B.

2.4.1. Entering the User Name and Password

Before the start page is shown, you will be prompted to enter the user name and password to gain the right to access the Web-based management interface. For first-time configuration,use the default user name “admin”and default password “smcadmin”,respectively.

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 start page shows the current settings and status of the SMC2582W-B, it can be saved or printed within the Web browser for future reference.

Fig. 6.The Start page.

2.4.2. Step 1:Selecting an Operational Mode

Fig. 7.Operational modes settings.

The SMC2582W-B supports 3 operational modes for meeting various wireless connectivity requirements:

• Access Point (AP).The AP mode 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 (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 functionality 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 SMC2582W-B forwards packets between its Ethernet interface and wireless 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 SMC2582W-Bs or between an SMC2582W-B and another wireless device.

• WDS. This type of wireless link is specified in the IEEE 802.11 standard for communication 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 SMC2582W-B 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 fol lowing 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 established between a Bridge Master and a Bridge Slave, but no wireless link can be established between a Bridge Slave and an AP.
