When a number of wireless stations are connected using a single access point, you have a Basic Service Set (BSS). In the ESS diagram below, communication is done through the access points, which relay data packets to other wireless stations or devices connected to the wired network. Wireless stations can then access resources, such as a printer, on the wired network.
In an ESS environment, users are able to move from one access point to another without losing the connection. In the diagram below, when the user moves from BSS (1) to BSS (2) the WLAN client devices automatically switches to the channel used in BSS (2).
Introduction The SMCWBR14-N is a high-performance, wireless router that supports high-speed wireless networking at home, at work or in public places. Unlike most routers, the SMCWBR14-N provides data transfers at up to 300Mbps when using 11n (Draft) connection. This router is also backwards compatible with 802.11g or 11b devices. This means that you do not need to change your entire network to maintain connectivity.
Hardware Overview Back Panel POWER The Power input connector is a single jack socket to supply power to the SMCWBR14-N. Please use the Power Adapter provided in the SMCWBR14-N package. RESET Pressing the reset button restores the router to its original factory default settings.
Front Panel LED’s POWER A solid green LED indicates the SMCWBR14-N is receiving power – normal operation. If the LED is off there is no power to device or failure. LAN1-4 A solid green LED indicates the corresponding LAN port connection is established. The LED blinks when data is transmitted. If the LED is off there is no link for corresponding LAN port. WAN A solid green LED indicates the WAN port connection is established. The LED blinks when data is transmitted.
Installation Considerations The SMCWBR14-N lets you access your network, using a wireless connection, from virtually anywhere within its operating range. Keep in mind, however, that the number, thickness and location of walls, ceilings, or other objects that the wireless signals must pass through, may limit the range. Typical ranges vary depending on the types of materials and background RF (radio frequency) noise in your home or business.

The SMCWBR14-N default IP address is: http://192.168.2.1 ¾ ¾ Open the Web browser. Type in the IP Address of the Router (http://192.168.2.1). If you have changed the default IP Address assigned to the SMCWBR14-N, make sure you enter the correct IP Address. ¾ ¾ ¾ Select Admin in the User Name field.
Basic The Basic tab provides the following configuration options: INTERNET, WIRELESS and NETWORK SETTINGS. Basic_Internet Setup Wizard If you are new to networking and have never configured a router before, click on Setup Wizard and the router will guide you through a few simple steps to get your network up and running. Manual Configure If you consider yourself an advanced user and have configured a router before, click Manual Configure to input all the settings manually.
Basic_Wireless The wireless section is used to configure the wireless settings for your router. Note that changes made in this section may also need to be duplicated on wireless clients that you want to connect to your wireless network. To protect your privacy, use the wireless security mode to configure the wireless security features. This device supports three wireless security modes including: WEP, WPA-Personal, and WPA-Enterprise. WEP is the original wireless encryption standard.
Enable Wireless This option allows you to enable/disable the wireless AP function. The wireless can also be turned ON/OFF by the slide switch on the back panel. When the wireless is enabled, the following parameters are in effect. Wireless Network Name When you are browsing for available wireless networks, this is the name that will appear in the list (unless Visibility Status is set to Invisible, see below). This name is also referred to as the SSID.
WEP network, you must know the key. The key is a string of characters that you create. When using WEP, you must determine the level of encryption. The type of encryption determines the key length. 128-bit encryption requires a longer key than 64-bit encryption. Keys are defined by entering in a string in HEX (hexadecimal - using characters 0-9, A-F) or ASCII (American Standard Code for Information Interchange - alphanumeric characters) format.
This option works with a RADIUS Server to authenticate wireless clients. Wireless clients should have established the necessary credentials before attempting to authenticate to the Server through this Gateway. Furthermore, it may be necessary to configure the RADIUS Server to allow this Gateway to authenticate users. Authentication Timeout: Amount of time before a client will be required to re-authenticate. RADIUS Server IP Address: The IP address of the authentication server.
Basic_Network Settings Use this section to configure the internal network settings of your router. The IP Address that is configured here is the IP Address that you use to access the Web-based management interface. If you change the IP Address here, you may need to adjust your PC’s network settings to access the network again.
Router Settings These are the settings of the LAN (Local Area Network) interface for the router. The router's local network (LAN) settings are configured based on the IP Address and Subnet Mask assigned in this section. The IP address is also used to access this Web-based management interface. It is recommended that you use the default settings if you do not have an existing network. IP Address The IP address of your router on the local area network.
Make this router the preferred destination for packets that are not otherwise destined. Allow RIP updates from WAN For security, disable this option unless required by the ISP. RIP Password RIP Version 2 supports the use of a password to limit access to routers through the RIP protocol. If the ISP or other LAN router requires a RIP password, enter the password here. DHCP Server Settings DHCP stands for Dynamic Host Configuration Protocol.
this falls within the "managed range" be sure to create a reservation for this address and match it to the relevant computer (see Static DHCP Client below). DHCP Lease Time The amount of time that a computer may have an IP address before it is required to renew the lease. The lease functions just as a lease on an apartment would. The initial lease designates the amount of time before the lease expires. If the tenant wishes to retain the address when the lease is expired then a new lease is established.
Windows 98 Windows Me Windows 2000 Windows XP Mac OS X Go to the Start menu, select Run, type in winipcfg, and hit Enter. A popup window will be displayed. Select the appropriate adapter from the pull-down menu and you will see the Adapter Address. This is the MAC address of the device. Go to your Start menu, select Programs, select Accessories, and select Command Prompt. At the command prompt type ipconfig /all and hit Enter.
Advanced The Advanced tab provides the following configuration options: Virtual Server, Special Applications, Gaming, StreamEngine, Routing, Access Control, WEB Filter, MAC Address Filter, Firewall, Inbound Filter, Advanced Wireless and Advanced Network. Advanced_Virtual Server The Virtual Server option gives Internet users access to services on your LAN. This feature is useful for hosting online services such as FTP, Web, or game servers.
2. Enter the IP Address of the machine on your LAN (for example: 192.168.2.50 3. Enter the Private Port as [80] 4. Enter the Public Port as [8888] 5. Select the Protocol (for example TCP). 6. Ensure the schedule is set to Always 7. Click Save to add the settings to the Virtual Servers List 8. Repeat these steps for each Virtual Server Rule you wish to add. After the list is complete, click Save Settings at the top of the page.
Add/Edit Virtual Server In this section you can add an entry to the Virtual Servers List below or edit an existing entry. Enable Entries in the list can be either active (enabled) or inactive (disabled). Save Saves the new or edited virtual server entry in the following list. When finished updating the virtual server entries, you must still click the Save Settings button at the top of the page to make the changes effective and permanent.
Advanced_Special Applications An application rule is used to open single or multiple ports on your router when the router senses data sent to the Internet on a "trigger" port or port range. An application rule applies to all computers on your internal network. Parameters for an Application Rule Example: You need to configure your router to allow a software application running on any computer on your network to connect to a web-based server or another user on the Internet.
Enter the outgoing port range used by your application (for example 6500-6700). Trigger Protocol Select the outbound protocol used by your application (for example Both). Input Port Range Enter the port range that you want to open up to Internet traffic (for example 6000-6200). Input Protocol Select the protocol used by the Internet traffic coming back into the router through the opened port range (for example Both). Schedule Select a schedule for when this rule is in effect.
Advanced_Gaming Multiple connections are required by some applications, such as internet games, video conferencing, Internet telephony, and others. These applications have difficulties working through NAT (Network Address Translation). This section is used to open multiple ports or a range of ports in your router and redirect data through those ports to a single PC on your network.
Give the rule a name that is meaningful to you, for example Game Server. You can also select from a list of popular games, and many of the remaining configuration values will be filled in accordingly. However, you should check whether the port values have changed since this list was created, and you must fill in the IP address field. IP Address Enter the local network IP address of the system hosting the server, for example 192.168.2.50.
Advanced_StreamEngine The StreamEngine feature helps improve your network gaming performance by prioritizing the data flows of network applications. StreamEngine Setup Enable StreamEngine Enable this option for better performance and experience with online games and other interactive applications, such as VoIP.
Automatic Classification This option is enabled by default so that your router will automatically determine which programs should have network priority. Dynamic Fragmentation This option should be enabled when you have a slow Internet uplink. It helps to reduce the impact that large low priority network packets can have on more urgent ones by breaking the large packets into several smaller packets.
that every flow defined in a rule receives the expected priority and avoids indeterminate prioritization that could reduce QoS effectiveness. Name Create a name for the rule that is meaningful to you. Priority The priority of the message flow is entered here -- 1 receives the highest priority (most urgent) and 255 receives the lowest priority (least urgent). Priority 0 is reserved. Flows that are not prioritized by any rule receive lowest priority. Protocol The protocol used by the messages.
Advanced_Routing Add/Edit Route Adds a new route to the IP routing table or edits an existing route. Enable: Specifies whether the entry will be enabled or disabled. Destination IP: The IP address of packets that will take this route. Netmask: One bits in the mask specify which bits of the IP address must match. Gateway: Specifies the next hop to be taken if this route is used. A gateway of 0.0.0.
Save: Saves the new or edited route in the following list. When finished updating the routing table, you must still click the Save Settings button at the top of the page to make the changes effective and permanent. Routes List The section shows the current routing table entries. Certain required routes are predefined and cannot be changed. Routes that you add can be changed by clicking the Edit icon, or deleted by clicking the Delete icon.
Advanced_Access Control The Access Control section allows you to control access in and out of devices on your network. Use this feature as Parental Controls to only grant access to approved sites, limit web access based on time or dates, and/or block access from applications such as peer-to-peer utilities or games. Enable By default, the Access Control feature is disabled. If you need Access Control, check this option.
This section shows the currently defined access control policies. A policy can be changed by clicking the Edit icon, or deleted by clicking the Delete icon. When you click the Edit icon, the Policy Wizard starts and guides you through the process of changing a policy. You can enable or disable specific policies in the list by clicking the "Enable" checkbox.
Advanced_WEB Filter This section is where you add the Web sites to be used for Access Control. The Web sites listed here are used when the Web Filter option is enabled in Access Control. The Web Filter section is one of two means by which you can specify the web sites you want to allow. You also have the alternative of using the Sentinel Parental Controls Service, which allows you to specify broad categories of web sites and saves you the trouble of entering specific web site URLs.
Enable Entries in the Allowed Web Site List can be activated or deactivated with this checkbox. New entries are activated by default. Save Saves the new or edited Allowed Web Site in the following list. When finished updating the Allowed Web Site List, you must still click the Save Settings button at the top of the page to make the changes effective and permanent. Allowed Web Site List The section lists the currently allowed web sites.
Advanced_MAC Address Filter The MAC address filter section can be used to filter network access by machines based on the unique MAC addresses of their network adapter(s). It is most useful to prevent unauthorized wireless devices from connecting to your network. A MAC address is a unique ID assigned by the manufacturer of the network adapter. Enable MAC Address Filter When this is enabled, computers are granted or denied network access depending on the mode of the filter.
Filter Wired Clients When this is selected, the MAC address filters will be applied to wired network clients. Add/Edit MAC Address In this section, you can add entries to the MAC Address List below, or edit existing entries. Enable MAC address entries can be activated or deactivated with this checkbox. MAC Address Enter the MAC address of the desired computer or connect to the router from the desired computer and click the Copy Your PC’s MAC Address button.
Advanced_Firewall The router provides a tight firewall by virtue of the way NAT works. Unless you configure the router to the contrary, the NAT does not respond to unsolicited incoming requests on any port, thereby making your LAN invisible to Internet cyber attackers. However, some network applications cannot run with a tight firewall. Those applications need to selectively open ports in the firewall to function correctly.
Firewall Settings Enable SPI SPI ("stateful packet inspection" also known as "dynamic packet filtering") helps to prevent cyber attacks by tracking more state per session. It validates that the traffic passing through that session conforms to the protocol. When the protocol is TCP, SPI checks that packet sequence numbers are within the valid range for the session, discarding those packets that do not have valid sequence numbers.
DMZ means "Demilitarized Zone." If an application has trouble working from behind the router, you can expose one computer to the Internet and run the application on that computer. When a LAN host is configured as a DMZ host, it becomes the destination for all incoming packets that do not match some other incoming session or rule.
Non-UDP/TCP/ICMP LAN Sessions When a LAN application that uses a protocol other than UDP, TCP, or ICMP initiates a session to the Internet, the router's NAT can track such a session, even though it does not recognize the protocol. This feature is useful because it enables certain applications (most importantly a single VPN connection to a remote host) without the need for an ALG. Note that this feature does not apply to the DMZ host (if one is enabled). The DMZ host always handles these kinds of sessions.
Allows FTP clients and servers to transfer data across NAT. Refer to the Advanced → Virtual Server page if you want to host an FTP server. H.323 (Netmeeting) Allows H.323 (specifically Microsoft Netmeeting) clients to communicate across NAT. Note that if you want your buddies to call you, you should also set up a virtual server for NetMeeting. Refer to the Advanced → Virtual Server page for information on how to set up a virtual server.
Advanced_Inbound Filter When you use the Virtual Server, Gaming, or Remote Administration features to open specific ports to traffic from the Internet, you could be increasing the exposure of your LAN to cyber attacks from the Internet. In these cases, you can use Inbound Filters to limit that exposure by specifying the IP addresses of internet hosts that you trust to access your LAN through the ports that you have opened.
Add/Edit Inbound Filter Rule Here you can add entries to the Inbound Filter Rules List below, or edit existing entries. Name Enter a name for the rule that is meaningful to you. Action The rule can either Allow or Deny messages. Source IP Range Define the ranges of Internet addresses this rule applies to. For a single IP address, enter the same address in both the Start and End boxes. Up to eight ranges can be entered. The Enable checkbox allows you to turn on or off specific entries in the list of ranges.
Advanced_Advanced Wireless Transmit Power Normally the wireless transmitter operates at 100% power. In some circumstances, however, there might be a need to isolate specific frequencies to a smaller area. By reducing the power of the radio, you can prevent transmissions from reaching beyond your corporate/home office or designated wireless area. Beacon Period Beacons are packets sent by a wireless router to synchronize wireless devices. Specify a Beacon Period value between 20 and 1000.
detect the beacons and awaken to receive the broadcast and multicast messages. The default value is 1. Valid settings are between 1 and 255. 802.11d Enable Enables 802.11d operation. 802.11d is a wireless specification for operation in additional regulatory domains. This supplement to the 802.11 specifications defines the physical layer requirements (channelization, hopping patterns, new values for current MIB attributes, and other requirements to extend the operation of 802.
Advanced_Network UPnP UPnP is short for Universal Plug and Play, which is a networking architecture that provides compatibility among networking equipment, software, and peripherals. This router has optional UPnP capability, and can work with other UPnP devices and software. Enable UPnP If you need to use the UPnP functionality, you can enable it here. WAN Ping Pinging public WAN IP addresses is a common method used by hackers to test whether your WAN IP address is valid.
WAN Port Speed Normally, this is set to "auto". If you have trouble connecting to the WAN, try the other settings. Multicast Streams The router uses the IGMP protocol to support efficient multicasting -- transmission of identical content, such as multimedia, from a source to a number of recipients. Enable Multicast Streams This option must be enabled if any applications on the LAN participate in a multicast group.
Tools The Tools tab provides the following configuration options: Admin, Time, Syslog, Email Settings, System, Firmware, Dynamic DNS, Windows Connect Now, System Check & Schedules.
