    SSID  The SSID (up to 32 printable ASCII characters) is the 
    unique name identified in a WLAN. The ID prevents the 
    unintentional merging of two co-located WLANs. The 
    default SSID of the router is “default”. 
      
    Beacon Interval  The interval of time that this wireless router broadcast a 
    beacon. Beacon is used to synchronize the wireless 
    network. The range for the beacon period is between 20 
    and 1000 with a typical value of 100 (milliseconds).  
      
    RTS/CTS Threshold  When the packet size is smaller than the RTS threshold, 
    the wireless router will not use the RTS/CTS mechanism 
    to send this packet. The range is from 1500 to 2347.  
      
    Fragmentation 
    Threshold Fragment Threshold specifies the maximum size of 
    packet during the fragmentation of data to be transmitted. 
    If you set this value too low, it will result in bad 
    performance. Enter a value from 256 to 2346. 
      
    DTIM  Determines the interval the Access Point will send its 
    broadcast traffic. The range is from 1 to 255 and the 
    default value is 3 beacons. 
      
    802.11b/g 802.11 b – This router will only work in 802.11b mode. If 
    there are only 802.11b wireless clients in the network, 
    you can set the router to this mode. 
     
      802.11 g – This router will only work in 802.11g mode. If 
    there are only 802.11g wireless clients in the network, 
    you can set the router to this mode.

    function is disabled. You can only set a set of SSID. 
      
    SSID  The SSID (up to 32 printable ASCII characters) is the 
    unique name identified in a WLAN. The ID prevents the 
    unintentional merging of two co-located WLANs. The 
    default SSID of the router is “default”. 
      
    Broadcast SSID  Select “Yes” to make the SSID to be visible so wireless 
    clients can scan the router within the network. Select 
    “No” if you want to hide the SSID of the router. Wireless 
    clients have to set the same SSID of the router in order 
    to access the network. 
      
    Authentication Type  To prevent unauthorized wireless clients from accessing 
    the router, this router supports WEP, WPA-PSK and 
    WPA2-PSK authentication type. If the router has enabled 
    the authentication, all the wireless clients’ settings have 
    to be consistent with the router for building the 
    connection. 
     
     
    z WEP/WPA-PSK/WPA2-PSK 
     
    Parameter Description 
    WEP-64Bits  WEP is less level of security than WPA. WEP supports 
    64-bit and 128-bit key lengths to encrypt the wireless 
    data. The longer key length will provide higher security. 
    When “WEP-64Bits” is selected, you have to enter 
    exactly 5 ASCII characters (“a-z” and “0-9”) or 10 
    hexadecimal digits (0-9, a-f) for each Key (1-4).

    hosts through RIP broadcasts. Select “No”, this routing 
    path will be kept private and it is not included in RIP 
    broadcasts. 
     
     
    5.3.3. NAT 
     
     
     
    5.3.3.1. NAT 
    Network Address Translation (NAT) allows multiple users at your local site to 
    access the Internet through a single Public IP Address or multiple Public IP 
    Addresses. NAT provides Firewall protection from hacker attacks and has the 
    flexibility to allow you to map Private IP Addresses to Public IP Addresses for key 
    services such as Websites and FTP. 
     
    Parameter Description 
    Virtual Circuit  VPI (Virtual Path Identifier) and VCI (Virtual Channel 
    Identifier define a virtual circuit. Please select the 
    channel (PVC) you want to configure. 
      
    NAT Status  The activated or deactivated status for the NAT function 
    will be shown here. 
      
    						
    							 40 Number of IPs  Select “Single” if you only have a public IP Address. 
    Select “Multiple” if you have multiple IP Addresses. 
     
    5.3.3.2. DMZ 
    The DMZ Host is a local computer exposed to the Internet. When setting a 
    particular internal IP Address as the DMZ Host, all incoming packets will be 
    checked by the firewall and NAT algorithms then passed to the DMZ Host. 
     
    For example, if you have a local client PC that cannot run an Internet application 
    (e.g. Games) properly from behind the NAT firewall, then you can open the client 
    up to unrestricted two-way Internet access by defining a DMZ Host. 
     
     
     
    Parameter Description 
    DMZ setting for  Show the DMZ setting is for single or multiple IP 
    Addresses. 
      
    DMZ  Enable or disable the DMZ function. 
     
    DMZ Host IP Address  Enter a static IP Address to the DMZ Host. This IP 
    Address will be exposed to the Internet. 
     
     
    5.3.3.3. Virtual  Server 
    Use the Virtual Server function when you want different servers/clients in your 
    LAN to handle different service/Internet application type (e.g. Email, FTP, Web  
    						
    							 41 server etc.) from the Internet. Computers use numbers called port numbers to 
    recognize a particular service/Internet application type. The Virtual Server allows 
    you to re-direct a particular service port number (from the Internet/WAN) to a 
    particular LAN private IP Address and its service port number. 
     
     
     
    Parameter Description 
    Virtual Server for  Show the Virtual Server setting is for single or multiple IP 
    Addresses. 
      
    Rule Index  Choose the rule number. 
    Application  Select the application of the virtual server, for example: 
    FTP or HTTP Server. When the application is selected, 
    the port number for the application will be assigned 
    automatically. 
    Parameter Description 
    Start Port Number  Enter the start port number. 
       
    						
    							 42 End Port Number  Enter the end port number. 
      
    Local IP Address  It is recommended to enter a static IP Address for the 
    server here. If the server’s IP Address is obtained from 
    DHCP Server, the IP Address may be changed 
    dynamically and will cause problem on this feature. 
    Please assign a static IP Address to the server and make 
    sure that the IP Address is not in the range of IP 
    Addresses that the DHCP Server will assign. 
     
    5.3.4. ADSL 
     
     
     
    Parameter Description 
    ADSL Mode  The default setting is “Auto Sync-Up”. This mode will 
    automatically detect the ADSL mode including ADSL2+, 
    ADSL2, G.DMT, T1.413 and G.lite. If you are not sure 
    how to select the ADSL mode, please contact with your 
    ISP. 
      
    ADSL Type  Check with your ISP about the ADSL type of the DSLAM 
    device they use.
