Then you need to click "Reboot" button to reboot the access point. The web browser loses connectivity with the AP web server as the access point reboots. To establish a network connection to the rebooted access point, wait until it has completed rebooting. Identification The SSID (Service Set Identification) is the name of a basic service set provided by an Access Point. All clients that want to connect to the Internet via an Access Point must set their SSIDs as the same as that of the Access Point. SSID: The Service Set ID. This should be set to the same value as other wireless devices in your network. (Default: ANY). 16 SYSTEM CONFIGURATION Channel Radio Channel: The radio channel through which the Access Point communicates to PCs in its BSS. (Default: "52" for US and "38" for Japan) Note that the DC channel for wireless clients is automatically set to the same as that used by the Access Point to which it is linked. Note: The available channel settings are limited to local regulations, which determine the number of channels that are available. - FCC: 8 channels - MKK: 5 channels Turbo Mode: You may either "Enable" or "Disable" the "Turbo Mode." (Default: Disable) The "Turbo Mode" is the enhanced wireless LAN operating mode (not regulated in the standard IEEE 802.11a) that can provide a higher data rate. The "Normal Mode" of the 802.11a access point provides connections up to 54 Mbps. Enabling the "Turbo Mode" on the 802.11a Access Point allows the AP to provide connections up to 72 Mbps data rate. 17 EZ CONNECTTM 802.11A WIRELESS ACCESS POINT Note: During "Normal Mode," the channel bandwidth is 20MHz. During "Turbo Mode," the channel bandwidth is increased to 40MHz. However, there will only be three channels available when the "Turbo Mode" is enabled (Only 1 channel in Japan). Performance Data Rate: Select "best" from the drop-down list to optimize the data transfer speed for your network. (Default: best) Transmit Power: Set the signal strength transmitted from the Access Point. The longer transmission distance, the higher transmission power required. (Default: full) Selections - "full," "half," "quarter" and "eighth" 18 SYSTEM CONFIGURATION Synchronization In order to obtain transmission, the Access Point and connected clients need to be synchronized. Beacon Interval (20-1000): Set the interval value of beacon between synchronized frames. These synchronous frames also contain indication of frames that need to transmit to the power-saved stations. (Default: 100) DTIM (1-16384): Set the Delivery Traffic Indication Message (DTIM) interval value. The DTIM indicates how often the MAC layer forwards multicast traffic. This parameter is necessary to accommodate stations using Power Save mode. In order to maximize the utilization of channels, broadcast data is not transmitted every beacon for stations in Power Save mode. These power-saved stations must wake up to receive broadcast data at the DTIM interval. 19 EZ CONNECTTM 802.11A WIRELESS ACCESS POINT The DTIM is the interval between two synchronous frames with broadcast information. If you set the value to 2, the access point will save all multicast frames for the BSS and forward them after every second beacon. Having smaller DTIM intervals delivers multicast frames in a more timely manner, causing stations in Power Save mode to wake up more often and drain power faster. Having higher DTIM values, though, delays the transmission of multicast frames. (Default: 1) Transmit Threshold Fragment Length (256-2346): The "Fragment Length" 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 can increase the reliability of transmission 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 SYSTEM CONFIGURATION RTS Length (256-2346): Set the RTS (Request to Send) frame length. You may configure the access point to initiate an RTS frame sequence always, never, or only on frames longer than a specified length. 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 send a CTS (Clear to Send) frame to acknowledge the right for the sending station to send data frames. The access point contending for the medium may not be aware of each other. The RTS/CTS mechanism can solve this "Hidden Node Problem." (Default: 2346) TCP / IP Settings Set the TCP/IP configuration for accessing the Internet. With DHCP Client "Enable," the IP address, subnet mask and default gateway can be dynamically assigned to the Access Point 21 by the network DHCP server. (Default: Disable) Note: If there is no DHCP server on your network, then the access point will automatically start up with its default IP address, 192.168.1.20. By using the Wireless Access Point's built-in DHCP (Dynamic Host Configuration Protocol) server, you are allowing the Wireless Access Point to handle all the IP addressing on your Local Area Network (LAN). 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) 22 SYSTEM CONFIGURATION Encryption Wired Equivalent Privacy (WEP) is implemented in this device to prevent unauthorized access to your wireless network. The WEP setting must be the same on each client in your wireless network. For more secure data transmission, you may set the WEP to prevent unauthorized access to your wireless network. Authentication Type You may choose either the "Open System" or the "Shared Key." (Default: Open System) 23 EZ CONNECTTM 802.11A WIRELESS ACCESS POINT If Shared Key is enabled, the WEP should be enabled and at least one shared key should be defined. But you can enable WEP, and set the authentication type as open system. Standard WEP Setup (WEP Default: Disable) Default Shared Key ­ Choose the Shared Key that has the encryption string you prefer (Key 1~4). 64-Bit Manual Entry Key 1~4 - Each Key ID contains 10 HEX digits. All wireless devices must have the same Key ID values to communicate. 128-Bit Manual Entry Key ID contains 26 HEX digits. All wireless devices must have the same Key ID values to communicate. 152-Bit Manual Entry Key ID contains 32 HEX digits. All wireless devices must have the same Key ID values to communicate. Advanced WEP Setup How to setup the Unique Key WEP: 1. Select a unique key (5 ~ 64) 2. Enter the encryption key and select the proper key size. 3. Click "Write" and "Apply" to save the encryption key. 4. If you want to read an encryption key, select the unique key you want to read, click "read" and "Apply" to read the encryption key. 5. If you want to delete an encryption key, select the unique key you want to delete, click "Delete" and "Apply" to delete the encryption key. 24 SYSTEM CONFIGURATION Using MAC Filter Set the MAC filter to filter out specified MAC addresses. The Access Control List (ACL) provides a mechanism to take certain actions based on the stations MAC address. Any frames with a source or destination MAC address entered in this table will be filtered from the Access Point. How to Setup the Access Control List: 1. Select ACL "Enable." 2. Enter an ACL ID (1 ~ 60) 3. Enter the MAC address of the station you want to setup. 4. Enter Key Map, should be one of the shared key (1 ~ 4) or one of the unique key (5 ~ 64), and choose "Allow" or "Deny." It means if the station's WEP key is the same as the Key Map you assigned, the station will allow connecting to the AP or deny connecting to the AP. 5. If you just enable the ACL, all stations that have shared keys can also connect to the AP. If you set the ACL to "Strict," only stations that MAC addresses in the ACL can connect to the AP. 25 EZ CONNECTTM 802.11A WIRELESS ACCESS POINT SNMP Use this screen to display and enter a community string for the Simple Network Management Protocol (SNMP). To communicate with the Access Point, the SNMP agent must first be enabled, and the Network Management Station must submit a valid community string for authentication. System Change Password Use this screen to change the password on the Access Point. 26 SYSTEM CONFIGURATION Factory Default Use the "Restore" button to load the factory default configuration and reboot this device. Note that all user configured information will be lost. You will also have to re-enter the password to regain management access to this device.

The SMC wireless network cards, adapters, access points and Wireless Access Point can be configured as: · · · Ad-hoc for departmental or SOHO LANs Infrastructure for wireless LANs Infrastructure wireless LAN for roaming wireless PCs 32 NETWORK CONFIGURATION AND PLANNING Network Topologies Ad-hoc Wireless LAN (no AP or Bridge) An ad-hoc wireless LAN consists of a group of computers, each equipped with a wireless adapter, connected via radio signals as an independent wireless LAN. Computers in a specific ad-hoc wireless LAN must therefore be configured to the same radio channel. An ad-hoc wireless LAN can be used for a branch office or SOHO operation. Ad-hoc Wireless LAN Notebook with Wireless USB Adapter Notebook with Wireless PC Card PC with Wireless PCI Adapter 33 Infrastructure Wireless LAN The SMC2755W can also provide access to a wired LAN for wireless workstations. An integrated wired/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 not only extends the accessibility of wireless PCs to the wired LAN, but also increases the effective wireless transmission range for wireless PCs by passing their signal through one or more 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 Access Point PC with Wireless PC I Adapter 34 NETWORK CONFIGURATION AND PLANNING 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) for the wireless card to the BSS ID of the Access Point to which you want to connect. Check with your administrator for the BSS ID of the access point or bridge 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 SMC wireless network cards and adapters and SMC2755W Wireless Access Point within a specific ESS must be configured with the same SSID.
