    4-2 Troubleshooting 
     
    If you found the router is working improperly or stop responding to you, 
    don’t panic! Before you contact your dealer of purchase for help, please 
    read this troubleshooting first. Some problems can be solved by you 
    within very short time! 
     
    Scenario Solution 
    Router is not 
    responding t o   m e 
    when I want to access 
    it by web browser 
    a. Please check the connection of power cord 
    and network cable of this router. All cords 
    and cables should be correc t l y   a n d   f i r m l y  
    inserted to the router. 
    b. I f  all L E Ds on this router are o f f, please 
    check the status of A/C power adapter, and 
    make sure it’s correctly powered. 
    c. You must use the same IP address section 
    which router uses. 
    d. Are you using MAC or IP address filter? 
    Try to connect the router by another 
    computer and see if it works; if not, please 
    restore your router to factory default 
    settings (pressing ‘reset’ button for over 10 
    seconds). 
    e. Set your computer to obtain an IP address 
    automatically (DHCP), and see if your 
    computer can get an IP address. 
    f. If you did a firmware upgrade and this 
    happens, contact your dealer of purchase for 
    help. 
    g. If all above solutions don’t work, contact 
    the dealer of purchase for help. 
    C a n’t get connected to 
    Internet 
    a. Go to ‘Status’ -> ‘Internet Connection’ 
    menu, and check Internet connection status. 
    b. Please be patient, sometime Internet is just 
    that slow. 
    c. If you connect a computer to Internet 
    directly before, try to do that again, and 
    check if you can get connected to Internet  
    						
    							125 
    with your computer directly attached to the 
    device provided by your Internet service 
    provider. 
    d. Check PPPoE / L2TP / PPTP user ID and 
    password again. 
    e. Call your Internet service provide and check 
    if there’s something wrong with their 
    service. 
    f. If you just can’t connect to one or more 
    website, but you can still use other internet 
    services, please check URL/Keyword filter. 
    g. Try to reset the router and try again later. 
    h. Reset the device provided by your Internet 
    service provider too. 
    i. Try to use IP address instead of hostname. I f  
    you can use IP address to communicate with 
    a remote server, but can’t use hostname, 
    please check DNS setting. 
    I can’t locate my 
    router by my wireless 
    client 
    a. ‘Broadcast ESSID’ set to off? 
    b. All two antennas are properly secured. 
    c. Are you too far from your router? Try to get 
    closer. 
    d. Please remember that you have to input 
    ESSID on your wireless client manually, if 
    ESSID broadcast is disabled. 
    File download is very 
    slow or breaks 
    frequently 
    a. Are you using QoS function? Try to disable 
    it and try again. 
    b. Internet is slow sometimes, being patient. 
    c. Try to reset the router and see if it’s better 
    after that. 
    d. Try to know what computers do on your 
    local network. If someone’s transferring big 
    files, other people will think Internet is 
    really slow. 
    e. If this never happens before, call you 
    Internet service provider to know if there is 
    something wrong with their network. 
    I can’t log onto web a. Make sure you’re connecting to the correct  
    						
    							126 
    management interface: 
    password is wrong 
    IP address of the router! 
    b. Password is case-sensitive. Make sure the 
    ‘Caps Lock’ light is not illuminated. 
    c. If you really forget the password, do a hard 
    reset. 
    Router become hot a. This is not a malfunction, if you can keep 
    your hand on the router’s case. 
    b. If you smell something wrong or see the 
    smoke coming out from router or A / C  
    power adapter, please disconnect the router 
    and A/C power adapter from utility power 
    (make sure it’s safe before you’re doing 
    this!), and call your dealer of purchase for 
    help. 
    The date and time of 
    all event logs are 
    wrong 
    a. Adjust the internal clock of router.

    4-3 Glossary 
     
     
    Default Gateway (Router): Every non-router IP device needs to configure a default 
    gateway’s IP address. When the device sends out an IP packet, if the destination is not 
    on the same network, the device has to send the packet to its default gateway, which 
    will then send it out towards the destination. 
    DHCP: Dynamic Host Configuration Protocol. This protocol automatically gives 
    every computer on your home network an IP address. 
    DNS Server IP Address: DNS stands for Domain Name System, which allows 
    Internet servers to have a domain name (such as www.Broadbandrouter.com) and one 
    or more IP addresses (such as 192.34.45.8). A DNS server keeps a database of 
    Internet servers and their respective domain names and IP addresses, so that when a 
    domain name is requested (as in typing "Broadbandrouter.com" into your Internet 
    browser), the user is sent to the proper IP address. The DNS server IP address used by  
    the computers on your home network is the location of the DNS server your ISP has 
    assigned to you.  
    DSL Modem: DSL stands for Digital Subscriber Line. A DSL modem uses your 
    existing phone lines to transmit data at high speeds.  
    Ethernet: A standard for computer networks. Ethernet networks are connected by 
    special cables and hubs, and move data around at up to 10/100 million bits per second 
    (Mbps).  
    Idle Timeout: Idle Timeout is designed so that after there is no traffic to the Internet 
    for a pre-configured amount of time, the connection will automatically be 
    disconnected. 
     
    IP Address and Network (Subnet) Mask: IP stands for Internet Protocol. An IP 
    address consists of a series of four numbers separated by periods, which identifies a 
    single, unique Internet computer host in an IP network. Example: 192.168.2.1. It 
    consists of 2 portions: the IP network address, and the host identifier. 
     
    The IP address is a 32-bit binary pattern, which can be represented as four cascaded 
    decimal numbers separated by “.”: aaa.aaa.aaa.aaa, where each “aaa” can be anything 
    from 000 to 255, or as four cascaded binary numbers separated by “.”: 
    bbbbbbbb.bbbbbbbb.bbbbbbbb.bbbbbbbb, where each “b” can either be 0 or 1.  
    						
    							128 
    A network mask is also a 32-bit binary pattern, and consists of consecutive leading 
    1’s followed by consecutive trailing 0’s, such as 
    11111111.11111111.11111111.00000000. Therefore sometimes a network mask can 
    also be described simply as “x” number of leading 1’s. 
    When both are represented side by side in their binary forms, all bits in the IP address 
    that correspond to 1’s in the network mask become part of the IP network address, and 
    the remaining bits correspond to the host ID.  
     
    For example, if the IP address for a device is, in its binary form, 
    11011001.10110000.10010000.00000111, and if its network mask is, 
    11111111.11111111.11110000.00000000 
    It means the device’s network address is  
    11011001.10110000.10010000.00000000, and its host ID is, 
    00000000.00000000.00000000.00000111. This is a convenient and efficient method 
    for routers to route IP packets to their destination. 
    ISP Gateway Address: (see ISP for definition). The ISP Gateway Address is an IP 
    address for the Internet router located at the ISP's office.  
    I S P :  Internet Service Provider. An ISP is a business that provides connectivity to the 
    Internet for individuals and other businesses or organizations.  
    LAN: Local Area Network. A LAN is a group of computers and devices connected 
    together in a relatively small area (such as a house or an office). Your home network 
    is considered a LAN.  
    MAC Address: MAC stands for Media Access Control. A MAC address is the 
    hardware address of a device connected to a network. The MAC address is a unique 
    identifier for a device with an Ethernet interface. It is comprised of two parts: 3 b y t e s  
    of data that corresponds to the Manufacturer ID (unique for each manufacturer), plus 
    3 bytes that are often used as the product’s serial number. 
    NAT: Network Address Translation. This process allows all of the computers on your 
    home network to use one IP address. Using the broadband router’s NAT capability, 
    you can access the Internet from any computer on your home network without having 
    to purchase more IP addresses from your ISP.  
    Port: Network Clients (LAN PC) uses port numbers to distinguish one network 
    application/protocol over another. Below is a list of common applications and 
    protocol/port numbers:  
    						
    							129 
    Application Protocol Port Number 
    Telnet TCP 23 
    FTP TCP 21 
    SMTP TCP 25 
    POP3 TCP 110 
    H.323 TCP 1720 
    SNMP UCP 161 
    S N M P   T r a p UDP 162 
    HTTP TCP 80 
    PPTP TCP 1723 
    PC Anywhere TCP 5631 
    PC Anywhere UDP 5632 
     
     
    PPPoE: Point-to-Point Protocol over Ethernet. Point-to-Point Protocol is a secure 
    data transmission method originally created for dial-up connections; PPPoE is for 
    Ethernet connections. PPPoE relies on two widely accepted standards, Ethernet and 
    the Point-to-Point Protocol. It is a communications protocol for transmitting 
    information over Ethernet between different manufacturers 
     
    Protocol: A protocol is a set of rules for interaction agreed upon between multiple 
    parties so that when they interface with each other based on such a protocol, the 
    interpretation of their behavior is well defined and can be made objectively, without 
    confusion or misunderstanding.  
     
    Router: A router is an intelligent network device that forwards packets between 
    different networks based on network layer address information such as IP addresses. 
    Subnet Mask: A subnet mask, which may be a part of the TCP/IP information 
    provided by your ISP, is a set of four numbers (e.g. 255.255.255.0) configured like an 
    IP address. It is used to create IP address numbers used only within a particular 
    network (as opposed to valid IP address numbers recognized by the Internet, which 
    must be assigned by InterNIC).  
    TCP/IP, UDP: Transmission Control Protocol/Internet Protocol (TCP/IP) and 
    Unreliable Datagram Protocol (UDP). TCP/IP is the standard protocol for data  
    						
    							130 
    transmission over the Internet. Both TCP and UDP are transport layer protocol. TCP 
    performs proper error detection and error recovery, and thus is reliable. UDP on the 
    other hand is not reliable. They both run on top of the IP (Internet Protocol), a 
    network layer protocol. 
     
    WAN: Wide Area Network. A network that connects computers located in 
    geographically separate areas (e.g. different buildings, cities, countries). The Internet 
    is a wide area network. 
     
    W e b-based management Graphical User Interface (GUI): Many devices support a 
    graphical user interface that is based on the web browser. This means the user can use 
    the familiar Netscape or Microsoft Internet Explorer to Control/configure or monitor 
    the device being managed.
