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 config

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

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.

The SMC2582W-B supports 3 operational modes for meeting various wireless connectivity require- ments: • 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 Maste
