    WEP –WEP is less level of security than WPA. WEP supports
    64-bit and 128-bit key lengths to encrypt the wireless data.
    WPA(TKIP) – WPA uses Temporal Key Integrity Protocol
    (TKIP) for data encryption. TKIP utilized a stronger encryption
    method and incorporates Message Integrity Code (MIC) to
    provide protection against hackers.
    WPA2(AES) – WPA2, also known as 802.11i, uses Advanced
    Encryption Standard (AES) for data encryption. AES utilized a
    symmetric 128-bit block data encryption.

    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 “WEP64Bits” 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).
    When “WEP-128Bits” is selected, you have to enter exactly 13
    ASCII characters (“a-z” and “0-9”) or 26 hexadecimal digits
    ("0-9", "a-f") for each Key (1-4).
    There are two types of authentication mode for WPA.
    Enterprise (RADIUS) – It uses an external RADIUS server
    to perform user authentication. To use RADIUS, enter the IP
    address of the RADIUS server, the RADIUS port (default is
    1812) and the shared secret from the RADIUS server. Please
    refer to “Authentication RADIUS Server” setting below for
    RADIUS setting.

    Personal (Pre-Shared Key) – Pre-Shared Key
    authentication is based on a shared secret that is known only
    by the parties involved. To use WPA Pre-Shared Key, select
    key format and enter a password in the “Pre-Shared Key
    Format” and “Pre-Shared Key” setting respectively.
    Pre-Shared Key You may select to select Passphrase (alphanumeric format) or
    Hexadecimal Digits (in the “A-F”, “a-f” and “0-9” range) to be
    the Pre-shared Key. For example:
    Passphrase: ”iamguest”
    Hexadecimal Digits: “12345abcde”
    Pre-Shared Key Please enter 8-63 characters as the “Pre-Shared Key”.

    This page allows advanced users who have sufficient knowledge of wireless LAN.
    These setting shall not be changed unless you know exactly what will happen
    for the changes you made on your router.

    Beacon Interval


    RTS Threshold

    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 1024 with a default value of 100 (milliseconds).
    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.
    This value should remain at its default setting of 2347.
    Should you encounter inconsistent data flow, only
    minor modifications are recommended. If a network
    packet is smaller than the preset “RTS threshold” size,
    the RTS/CTS mechanism will not be enabled. The
    wireless router sends Request to Send (RTS) frames to
    a particular receiving station and negotiates the
    sending of a data frame. After receiving an RTS, the
    wireless station responds with a Clear to Send (CTS)
    frame to acknowledge the right to begin transmission.

  • Page 31

    Broadcast SSID

    If this option is enabled, the router will automatically
    transmit the network name (SSID) into open air at
    regular interval. This feature is intended to allow
    clients to dynamically discover the router. If this option
    is disabled, the router will hide its SSID. When this is
    done, the clients cannot directly discover the router
    and MUST be configure with the SSID for accessing to
    the router. It is used to protect your network from
    being accessed easily.

    When you finish, click ‘save’ to save the settings made and restart the router so
    the settings will take effect after it reboots.

    QoS allows you to classify Internet application traffic by source/destination IP
    address and port number. You can assign priority for each type of application and
    reserve bandwidth for it. The packets of applications with higher priority will
    always go first. Lower priority applications will get bandwidth after higher priority
    applications get enough bandwidth. This can let you have a better experience in
    using critical real time services like Internet phone, video conference …etc. All the
    applications not specified by you are classified as rule name “Others”. The rule
    with a smaller priority number has a higher priority; the rule with a larger priority
    number has a lower priority. You can adjust the priority of the rules by moving
    them up or down.

    The page enables you to define specific route for your Internet and network
    Most users do not need to define routes. On a typical small home or office LAN,
    the existing routes that set up the default gateways for your LAN hosts and for
    the router provide the most appropriate path for all your Internet traffic.
    You may need to define routes if your home setup includes two or more
    networks or subnets, if you connect to two or more ISP services, or if you
    connect to a remote corporate LAN.

    As a bidirectional SOAP/HTTP-based protocol, it provides the communication
    between customer-premises equipment (CPE) and Auto Configuration Servers
    (ACS). It includes both a safe auto configuration and the control of other CPE
    management functions within an integrated framework. In the course of the
    boom of the broadband market, the number of different Internet access
    possibilities grew as well (e.g. modems, routers, gateways, set-top box, VoIPphones). At the same time the configuration of this equipment became more
    complicated -- too complicated for the end-users. For this reason the TR-069
    standard was developed. It provides the possibility of auto configuration of these
    access types. The technical specifications are managed and published by
    the Broadband Forum. Using TR-069, the terminals can get in contact with the
    Auto Configuration Servers (ACS) and establish the configuration automatically.
    Accordingly other service functions can be provided. TR-069 is the current
    standard for activation of terminals in the range of DSL broadband market.

    14 Firewall Settings
    The Broadband router provides extensive firewall protection by restricting
    connection parameters, thus limiting the risk of hacker attacks, and defending
    against a wide array of common Internet attacks. However, for applications that
    require unrestricted access to the Internet, you can configure a specific
    client/server as a Demilitarized Zone (DMZ).

    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 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 Port) to a particular LAN private IP address and its service
    port number.
