    Setting up an Ethernet network
    We recommend using category 5, unshielded, twisted-pair cable (approximately 1/4” in 
    diameter with a thin outer-jacket, containing eight color-coded wires), and equipment 
    compatible with this type of cable. This type of cable is equipped with RJ-45 connectors 
    (like a large telephone jack connector, but with eight pins) on each end.

    Chapter 5: Networking Your Computer
    Setting up a network using a router
    If you are setting up a network for more than two computers and you will be connecting 
    your network to a high-speed Broadband Internet connection (cable or DSL modem), we 
    recommend the use of a router. A router lets you access the Internet connection from any 
    network computer. The router can assign IP addresses to the computers on the network 
    and can provide firewall protection for your network as well. 
    In addition to a router, you need a straight-through cable for each computer you want to 
    connect to the network.
    ImportantCategory 5 cables are available in two different types; 
    straight-through cables, used to connect computers to a router, and 
    crossover cables, used to connect two computers.
    To determine which type of cable you have, hold both ends of the 
    cable with the connectors facing away from you and with the spring 
    clip on the bottom. For straight-through cable, the wires on both 
    connectors are attached to copper pins in the same order (same 
    colors, left to right). For a crossover cable, the wires on each 
    connector are attached to the copper pins in a different order (different 
    colors, left to right).

    Testing your network
    Configuring your router
    After you have named your computers and set up TCP/IP on them, you can configure your 
    router using your Web browser. Check your router documentation for information about 
    installing it and setting network security.
    Testing your network
    Now that your home network is set up, log onto one of your computers and access a favorite 
    Internet Web site.
    If you are unable to connect to the Internet:
    ■Run the New Connection Wizard
    ■Check all physical cable connections
    ■Compare the status lights on the front of the router with the patterns described 
    in the router literature
    ■Temporarily turn off any firewall software on your desktop computer
    ■Turn off all of the devices, then power them back on
    ■Refer to your router’s troubleshooting information
    ■Contact your Internet service provider
    ■Review the troubleshooting information on page 92.
    Using your computer on your network
    With a network, you can share your Internet connection, drives, and printers. For 
    information about using your computer on a network, see “Using your computer on a 
    network” in Using Your Computer which has been included on your hard drive. To access 
    this guide, click 
    Start, All Programs, then click Gateway Documentation.

    Chapter 6: Maintaining Your Computer
    Caring for your computer
    To extend the life of your computer:
    ■When transporting your computer, we recommend that you put it in the original 
    packaging materials.
    ■Keep diskettes and your computer away from magnetic fields. Magnetic fields can 
    erase data on both diskettes and hard drives.
    ■Avoid subjecting your computer to extreme temperature changes.
    ■Keep all liquids away from your computer. When spilled onto computer 
    components, almost any liquid can result in extremely expensive repairs that are 
    not covered under your warranty.
    ■Avoid dusty or dirty work environments. Dust and dirt can clog the internal 
    mechanisms.
    ■Do not block the ventilation fan.
    ■When storing your computer for an extended period of time, unplug AC power.
    Updating Windows
    Windows Update is the online extension of Windows that helps you to keep your computer 
    up-to-date. Use Windows Update to choose updates for your computer’s operating system, 
    software, and hardware. New content is added to the site regularly, so you can always get 
    the most recent updates and fixes to protect your computer and keep it running smoothly.

    Protecting your computer from viruses
    Protecting your computer from viruses
    A virus is a program that attaches itself to a file on a computer, then spreads from one 
    computer to another. Viruses can damage data or cause your computer to malfunction. 
    Some viruses go undetected for a period of time because they are activated on a certain date.
    Protect your computer from a virus by:
    ■Registering your copy of Norton® Internet Security and subscribing to the virus 
    definition update service. You received a free limited time subscription to the 
    Norton Internet Security service when you purchased your computer.
    ■Using the Norton Internet Security program to check files and programs that are 
    attached to e-mail messages or downloaded from the Internet.
    ■Checking all programs for viruses before installing them.
    ■Disabling macros on suspicious Microsoft Word and Excel files. These programs 
    will warn you if a document that you are opening contains a macro that might 
    have a virus.
    ■Periodically updating the Norton Internet Security program to protect against the 
    latest viruses.
    ■Making sure the Windows Security Center is configured to provide you with the 
    highest level of protection.
    Help and 
    SupportFor more information about protecting your computer against viruses,

    Cleaning your computer
    Keeping your computer clean and the vents free from dust helps keep your computer 
    performing at its best. You may want to gather these items and put together a computer 
    cleaning kit:
    ■A soft, lint-free cloth
    ■An aerosol can of air that has a narrow, straw-like extension
    ■Cotton swabs
    ■A CD or DVD drive cleaning kit
    Cleaning the exterior
    Always turn off your computer and other peripherals before cleaning any components. 
    Use a damp, lint-free cloth to clean your computer and other parts of your system. Do 
    not use abrasive or solvent cleaners because they can damage the finish on components.
    Your computer is cooled by air circulated through the vents on the case, so keep the vents 
    free of dust. With your computer turned off and unplugged, brush the dust away from 
    the vents with a damp cloth. Be careful not to drip any water into the vents. Do not attempt 
    to clean dust from the inside of your computer.
    Cleaning the keyboard
    You should clean the keyboard occasionally by using an aerosol can of air with a narrow, 
    straw-like extension to remove dust and lint trapped under the keys.
    If you spill liquid on the keyboard, turn off your computer and turn the keyboard upside 
    down. Let the liquid drain, then let the keyboard dry before trying to use it again. If the 
    keyboard does not work after it dries, you may need to replace it.
    WarningWhen you shut down your computer, the power turns off, but some 
    electrical current still flows through your computer. To avoid possible 
    injury from electrical shock, unplug the power cord and modem cable 
    from the wall outlets.
