The following table outlines the selections available from this program. Menu System LAN Wireless Filter Tools Description Sets the password for administrator access, and the IP address of a PC that will be allowed to manage the Wireless Access Point remotely Sets the TCP/IP configuration of the Wireless Access Points LAN interface and all DHCP clients Configures the wireless channel, SSID, and encryption for wireless communications Configures control access to your network clients based on the MAC (Media Access Control) Address of the client machine Contains options to backup & restore the current configuration, restore all configuration settings to the factory defaults, update system firmware, or reset the system Provides WAN connection type and status, firmware and hardware version numbers, system IP settings, as well as DHCP, NAT, and Firewall information. Displays the number of attached clients, the firmware versions, the physical MAC address for each media interface, and the hardware version and serial number. 11 SYSTEM CONFIGURATION System Password Settings Use this menu to restrict access based on a password. By default, there is no password. For security you should assign one before exposing the SMC2671W to the Internet. Passwords can contain from 312 alphanumeric characters and are not case sensitive. Enter a maximum Idle Time Out (in minutes) to define a maximum period of time for which the login session is maintained during inactivity. If the connection is inactive for longer than the maximum idle time, it will perform system logout, and you have to login to the web management system again. (Default:

10 minutes) 12 NAVIGATING THE WEB BROWSER INTERFACE System Settings System Settings allows a remote PC to configure, manage, and monitor the SMC2671W using a standard web browser. Check Enable and enter the IP address of the remote host. Click APPLY. Note: If you specify 0.0.0.0 as this IP address, any host can manage the SMC2671W. 13 SYSTEM CONFIGURATION LAN With Obtain an IP Address Automaticly [DHCP] enabled, the IP address, subnet mask and default gateway can be dynamically assigned to the SMC2671W by the network DHCP server.

(Default: Disable) Note: If there is no DHCP server on your network, then the SMC2671W will automatically start up with its default IP address, 192.168.2.254. By using the SMC2671Ws built-in DHCP (Dynamic Host Configuration Protocol) server, you are allowing the SMC2671W to handle all the IP addressing on your Local Area Network (LAN)

(when in Access Point mode). This can save you much of the time and hassle of setting up your network. If you have a server on your network that requires a static IP address, you may still use the DHCP Server and manually assign a static IP address to your server. (Default: Disable) 14 NAVIGATING THE WEB BROWSER INTERFACE If your Internet Service Provider has assigned a fixed IP address, select Configure a Static IP Address. Enter the assigned address and subnet mask for the SMC2671W then enter the gateway address of your ISP. You may need a fixed address if you want to provide Internet services, such as a web server or FTP server. Wireless To configure the SMC2671W as an Ethernet Converter, all you need to do is define the radio channel, the Service Set identifier

(SSID), and encryption options. Channel and SSID If the SMC2671W is in Access Point mode you must specify a common radio channel and SSID (Service Set ID) to be used by the Wireless Access Point and all of your wireless clients. Be sure you configure all of your clients to the same values. In Ethernet Converter or Repeater mode, the radio channel and 15 SYSTEM CONFIGURATION SSID (Service Set ID) of the SMC2671W must be set to the same values as those of the access point they are associated with. Wireless Channel: The radio channel through which a wireless access point communicates with PCs in its BSS. (Default: 7) Note: The available channel settings are limited by local regulations. SSID: The Service Set ID. This should be set to the same value as other wireless devices in your network. (Default: WLAN.) Note: The SSID is case sensitive and can consist of up to 32 alphanumeric characters. Broadcast SSID: In Access Point or Repeater Mode, the SMC2671W can be enabled to broadcast the SSID on the wireless network for easy connection with client PCs.

(Default: Enable) WEP Encryption If you are transmitting sensitive data across wireless channels, you should enable Wired Equivalent Privacy (WEP) encryption. Encryption requires you to use the same set of encryption/

decryption keys for a wireless access point and all of its wireless clients. The SMC2571W supports shared key encryption with key lengths of the standard 64-bit and industry standard 128-bit. The bit key must be in hexadecimal numerals.

(0~9, A~F, e.g., D7 0A 9C 7F E5.) 16 NAVIGATING THE WEB BROWSER INTERFACE 64-Bit Manual Entry Key 1~4 - Each Key ID contains 10 HEX digits. 128-Bit Manual Entry Key ID contains 26 HEX digits. You may automatically generate encryption keys or manually enter the keys. For automatic 64-bit security, enter a passphrase. Four keys will be generated (as shown above). Choose a key from the four generated keys. Automatic 128-bit security generates a single passphrase. Note that Wired Equivalent Privacy (WEP) protects data transmitted between wireless nodes, but does not protect any transmissions over your wired network or over the Internet. 17 SYSTEM CONFIGURATION Client List The Client List screen displays the MAC address and network speed of the accociated clients. Note that the client list will be blank if the SMC2671W is in Ethernet Converter mode. 18

NAVIGATING THE WEB BROWSER INTERFACE Advanced Settings Operation Mode: This may be set to Access Point, Repeater or Ethernet Converter. These modes are described below:

Access Point functions as a standard IEEE 802.11b access point Repeater repeats an access points signals to extend the acess points coverage Ethernet Converter provides a wireless connection to an access point via an RJ-45 connection to devices such as Microsoft Xbox and Ethernet ready embedded devices 19 SYSTEM CONFIGURATION The parameters that follow may be configured in any of the three modes descibed above but the user is advised to leave them at their default settings. Transmission Rate: Set the data rate transmitted from the Wireless Access Point. The lower the data rate, the longer the transmission distance.

(Default: Fully Automatic.) RTS Threshold: Set the RTS (Request to Send) frame length. You may configure the access point to initiate an RTS frame. If the packet size is smaller than the preset RTS threshold size, the RTS/CTS mechanism will NOT be enabled The access point sends Request to Send (RTS) frames to a particular receiving station to negotiate the sending of a data frame. After receiving an RTS, the station sends a CTS (Clear to Send) frame to acknowledge the right of the sending station to send data frames. The access points contending for the medium may not be aware of each other. The RTS/CTS mechanism can solve this Hidden Node Problem. (Default: 2347) Fragmentation Threshold: The Fragmentation Threshold can be set between 256 and 2,346. If the packet size is smaller than the preset Fragment size, the packet will not be segmented. Fragmentation of the PDUs (Package Data Unit) can increase the reliability of transmissions because it increases the probability of a successful transmission due to smaller frame size. If there is significant interference present, or collisions due to high network utilization, try setting the fragment size to send smaller fragments. This will enable the retransmission of smaller frames much faster. However, it is more efficient to set the fragment size larger if very little or no interference is present because it requires overhead to send multiple frames. (Default: 2346) 20 NAVIGATING THE WEB BROWSER INTERFACE Basic Rate: The highest rate specified is the rate the Wireless Access Point will use when transmitting broadcast/multicast and management frames.

(Default: 1, 2 Mbps.) Preamble Type: The access points and client card drivers have a radio setting for RF Preamble. Enabling it can boost your throughput. Preamble Type offers a drop-down list with two options: Long or Short. If you are not sure whether all the clients and access point radios in your wireless network support the Short RF preamble, then leave this setting on Long (default). Transmit Power: Set the signal strength transmitted from the access point. The longer the transmission distance, the higher the transmission power required. (Default:

Super) Selections - Weak, Medium, Normal, High and Super 21 SYSTEM CONFIGURATION Filter The MAC Filtering feature of the SMC2671W allows you to control access to your network clients based on the MAC (Media Access Control) Address of the client machine. This ID is unique to each network adapter. If the MAC address is listed in the table, that client machine will not have access to the network. 22 NAVIGATING THE WEB BROWSER INTERFACE Tools Use the Tools menu to backup the current configuration, restore a previously saved configuration, restore factory settings, update firmware, and reset the SMC2671W.

Ad hoc for small departmental or SOHO LANs Infrastructure for enterprise LANs Network Topologies Ad Hoc Wireless LAN Ad Hoc Wireless LAN Notebook with Wireless USB Adapter SMC2671 in Ethernet Converter Mode Notebook with Wireless PC Card An ad hoc wireless LAN consists of a group of computers, each equipped with a wireless adapter or Ethernet converter, connected via radio signals as an independent wireless LAN. Computers in a specific ad hoc wireless LAN must be configured to the same radio channel. An ad hoc wireless LAN can be used for a small branch office or SOHO operation. 35 NETWORK CONFIGURATION AND PLANNING Infrastructure Wireless LAN An integrated wired and wireless LAN is called an Infrastructure configuration. A Basic Service Set (BSS) consists of a group of wireless PC users, and an access point that is directly connected to the wired LAN. Each wireless PC in this BSS can talk to any computer in its wireless group via a radio link, or access other computers or network resources in the wired LAN infrastructure via the access point. The infrastructure configuration permits wireless clients to access the wired LAN and also increases the effective wireless transmission range for wireless clients as their signal can be passed through multiple access points. A wireless infrastructure can be used for access to a central database, or for connection between mobile workers, as shown in the following figure. Wired LAN Extension to Wireless Adapters File Server Desktop PC Switch Notebook with Wireless PC Card Adapter SMC2671W in Access Point Mode PC with Wireless PCI Adapter 36 NETWORK TOPOLOGIES Infrastructure Wireless LAN for Roaming Wireless PCs The Basic Service Set (BSS) is the communications domain for each wireless access point. For wireless PCs that do not need to support roaming, set the domain identifier (SSID) of the wireless card to the SS ID of the access point to which you want to connect. Check with your administrator for the SS ID of the access point to which he wants you to connect. A wireless infrastructure can also support roaming for mobile workers. More than one access point can be configured to create an Extended Service Set (ESS). By placing the Access Points so that a continuous coverage area is created, wireless users within this ESS can roam freely. All wireless network cards, adapters, and the wireles access point within a specific ESS must be configured with the same SSID. Note: If Access Point 2 is replaces by an SMC2671W set to Repeater mode then the SMC2761W will not establish its own BSS, but will repeat data messeges between Acess Point 1 and end users, thus extending the coverage area of Access Point 1.

Access Point An internetworking device that seamlessly connects wired and wireless networks. Ad Hoc An ad hoc wireless LAN is a group of computers each with LAN adapters, connected as an independent wireless LAN. Backbone The core infrastructure of a network. The portion of the network that transports information from one central location to another central location where it is unloaded onto a local system. Base Station In mobile telecommunications, a base station is the central radio transmitter/receiver that maintains communications with the mobile radio telephone sets within its range. In cellular and personal communications applications, each cell or micro-cell has its own base station; each base station in turn is interconnected with other cells bases. BSS BSS stands for Basic Service Set. It is an Access Point and all the LAN PCs that are associated with it. CSMA/CA Carrier Sense Multiple Access with Collision Avoidance. ESS ESS (ESS-ID, SSID) stands for Extended Service Set. More than one BSS is configured to become an Extended Service Set. LAN mobile users can roam between different BSSs in an ESS (ESS-ID, SSID). 43 TERMINOLOGY Ethernet A popular local area data communications network, which accepts transmission from computers and terminals. Ethernet operates on a 10 Mbps baseband transmission rate, using a shielded coaxial cable or shielded twisted pair telephone wire. Infrastructure An integrated wireless and wired LAN is called an Infrastructure configuration. Fragmentation Threshold In the 802.11 Standard, the MAC Layer may fragment and reassemble directed MSDUs or MMPDUs. The fragmentation and defragmentation mechanisms allow for fragment re-transmission. Preamble Type Some access points and client card drivers have a radio setting for Short RF Preamble. If all the clients and access points in your wireless network have this feature, then enabling it can boost your throughput. However, if a radio does not support this feature, then it will not be able to communicate with any other radios that have this set to Short. Roaming A wireless LAN mobile user moves around an ESS and maintains a continuous connection to the Infrastructure network. RTS Threshold Transmitters contending for the medium may not be aware of each other. RTS/CTS mechanism can solve this Hidden Node Problem. If the packet size is smaller than the preset RTS Threshold size, the RTS/CTS mechanism will NOT be enabled. WEP Wired Equivalent Privacy is based on the use of 64-bit or 128-bit keys and the popular RC4 encryption algorithm. Wireless devices without a valid WEP key will be excluded from network traffic. 44 FOR TECHNICAL SUPPORT, CALL:
