Then select one shared key (1 ~ 4) and the proper key size. (WEP Default: Disable) 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. 64-Bit Manual Entry Key 1~4 - Each Key ID contains 10 HEX digits.
SYSTEM CONFIGURATION Advanced Setup Click the “Advanced setup” on the right bottom corner to display additional information about the Access Point configuration as shown below: 15
EZ CONNECT™ 802.11A WIRELESS ACCESS POINT Note: The “Advanced Setup” screen allows you to view and change the current configurations of the Access Point. After modifying the configuration parameters, you must click on the “Apply” button to save the changes. The new settings will not take effect until you click “Apply” to refresh the Access Point. 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.
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.
EZ CONNECT™ 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.
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.
EZ CONNECT™ 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.
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.
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.
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.
EZ CONNECT™ 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.
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.

EZ CONNECT™ 802.11A WIRELESS ACCESS POINT NETWORK CONFIGURATION AND PLANNING SMC’s EZ Connect Wireless Solution supports a stand-alone wireless network configuration as well as an integrated configuration with 10/100 Mbps Ethernet LANs.
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.
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.
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.
EZ CONNECT™ 802.11A WIRELESS ACCESS POINT TROUBLESHOOTING Check the following items before you contact SMC Technical Support. 1. If mobile users do not have roaming access to the SMC2755W Wireless Access Point, check the following: Make sure that all the SMC2755Ws and wireless devices in the ESS in which the WLAN mobile users can roam are configured to the same WEP setting, SSID, and authentication algorithm. 2.
