Fig. 3. Mounting the SMC2582W-B on a wall. 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.
Fig. 4. Connecting a managing computer and an SMC2582W-B via Ethernet. You can use 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.
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.
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).
Select an operational mode and click Save at the bottom of this page, and then you are brought back to the start page. 2.4.3. 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. 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.
If the SMC2582W-B was configured to be in AP or Bridge Master mode, and you want to use WDS to establish inter-SMC2582W-B 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 SMC2582W-Bs with MAC addresses 00-02-65-01-62-C5 and 0002-65-01-62-C6 to establish a WDS link between them.

3.6. Configuring Advanced Settings 3.6.1. Packet Filters The SMC2582W-B 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 filters 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.
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 resultant source IP address range is 192.168.0.0 to 192.168.0.
3.6.2.3. System Log Fig. 53. System log settings. System events can be logged to the on-board RAM of the SMC2582W-B (Local log) or sent in 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.

Appendix A: Default Settings TIP: Press the Default switch on the housing of a powered-on SMC2582W-B to reset the configuration settings to factory-default values.
Appendix B: Troubleshooting Check the following first: • Make sure that the power of the SMC2582W-B is on and the Ethernet cables are connected firmly to the RJ-45 jacks of the SMC2582W-B. • Make sure that the LED ALV of the SMC2582W-B is blinking to indicate the SMC2582W-B is working. • Make sure the types of the Ethernet cables are correct. Recall that there are two types— normal and crossover. B-1: Wireless Settings Problems • The wireless client computer cannot associate with an SMC2582W-B.
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 request to the default gateway of the client computer. Finally, this request is forwarded by the gateway to the DNS server on the Internet.
• Solve the preceding problem first. • Are the IP address of the SMC2582W-B and the IP address of the client computer in the same IP subnet? • If you cannot find any incorrect settings of the SMC2582W-B, the default gateway may be really down or there are other communication problems on the network backbone. • The DNS server(s) of the client computer do not respond to ping from the client computer. • Solve the preceding problems first.
• My SMC2582W-B stops working and does not respond to Web management requests. • The firmware of the SMC2582W-B may be stuck in an incorrect state. • Unplug the power connector from the power jack, and then re-plug the connector to restart the SMC2582W-B. • Contact our technical support representatives to report this problem. • If this happens after a failed firmware upgrade process, the firmware of the SMC2582W-B may have been corrupted.
