    Using a wired Ethernet network
    A wired Ethernet network consists of two or more computers connected 
    together through an Ethernet cable. This connection type is commonly used 
    in offices around the world and can be used to build computer networks in 
    the home.
    Ethernet, Fast Ethernet, or Gigabit Ethernet
    Ethernet is available at three different speeds. Standard Ethernet runs at 
    10 Mbps, Fast Ethernet runs at 100 Mbps, and Gigabit Ethernet runs at 
    1000 Mbps. Most home networks are built using Standard or Fast Ethernet 
    components. Business networks are typically built using Fast or Gigabit Ethernet 
    components.
    To create a wired Ethernet network, you or your electrician must:
    ■Install special Ethernet cables in your home or office
    ■Install an Ethernet card in each of your desktop computers (if your 
    computers do not already have built-in Ethernet jacks)
    ■Install an Ethernet PC Card in each of your notebooks or convertible 
    tablet PCs (if your notebooks or convertible tablet PCs do not already have 
    built-in Ethernet jacks)
    ■Install an Ethernet router, switch, or hub
    ImportantCheck local code requirements before installing Ethernet 
    cable or other wiring in your home or office. Your 
    municipality may require you to obtain a permit and hire 
    a licensed installer.
    Tips & TricksIf you are connecting just two computers (known as a 
    peer-to-peer wired Ethernet network), you can eliminate 
    the router, switch, or hub and use a special crossover 
    cable.

    Example wired Ethernet network
    The following is an example of a wired Ethernet network. The network is made 
    up of a router, a cable or DSL modem, your computers, and cables connecting 
    each of these components. The router is the central control point for the 
    network. Attached to the router are all of your computers or Ethernet-ready 
    devices. Also connected to the router is a cable or DSL modem that provides 
    access to the Internet.
    Tips & TricksTo add the ability to access a wireless Ethernet network 
    to your wired Ethernet network, connect an access point 
    to the router, switch, or hub. For more information about 
    accessing a wireless Ethernet, see “Using a wireless 
    Ethernet network” on page 204.

    Equipment you need for a wired Ethernet 
    network
    For a wired Ethernet network you need:
    ■An Ethernet jack on each desktop computer, notebook, tablet PC, and 
    convertible tablet PC.
    - OR -
    An Ethernet card (also called network interface cards or NICs) installed in 
    each desktop computer.
    - OR -
    An Ethernet PC Card installed in each notebook or convertible tablet PC.
    ■An Ethernet router. Select a router that gives you the following features:
    ■A jack for connecting to a cable or DSL modem.
    ■The ability to assign IP addresses to your networked computers 
    dynamically. This prevents intruders from seeing the computers over 
    the Internet.
    ■A built-in firewall to protect the computers on your network from 
    intruders trying to access your data over the Internet.
    ■Built-in switching (with enough ports for all computers and devices 
    on the network) so you will not have to purchase a hub or switch.
    ■If you did not purchase a router that includes built-in switching or if the 
    router does not have enough ports to attach all of your computers, an 
    Ethernet hub or switch with enough ports for all computers and devices 
    in the network.
    ■Ethernet cable going from each computer to the router, hub, or switch.
    ImportantFor best results, all Ethernet components should be either 
    standard Ethernet (10 Mbps), Fast Ethernet (100 Mbps or 
    10/100), or Gigabit Ethernet (1000 Mbps or 10/100/1000). 
    A mixture of components rated at different speeds will 
    result in your network running at the speed of the slowest 
    rated component.

    Using a wireless Ethernet network
    A wireless Ethernet network is ideal for creating a home or office network or 
    adding mobility to an existing wired Ethernet network. A wireless Ethernet 
    network allows you the freedom to move about your home or office with your 
    notebook, tablet PC, or convertible tablet PC. For example, you can take your 
    notebook, tablet PC, or convertible tablet PC from your home office to your 
    patio without having an Ethernet jack available.
    WarningRadio frequency wireless communication can interfere 
    with equipment on commercial aircraft. Current aviation 
    regulations require wireless devices to be turned off while 
    traveling in an airplane. IEEE 802.11a, IEEE 802.11b, and 
    IEEE 802.11g communication devices are examples of 
    devices that provide wireless communication. For 
    instructions to turn wireless Ethernet on and off, see 
    “Turning your wireless Ethernet emitter on or off” on 
    page 210.
    ImportantIf your convertible tablet PC came equipped with an 
    internal radio frequency wireless device, see “Safety, 
    Regulatory, and Legal Information” on page 309 for 
    general wireless regulatory and safety guidelines. To find 
    out if your convertible tablet PC has an internal wireless 
    device, check the label (see “Identifying your model” on 
    page 10) or the device manager.

    Wireless Ethernet speed and frequency
    Wireless Ethernet is available at two different speeds and at two different 
    frequencies. The following table compares the various wireless Ethernet 
    network types.
    The two most common types of wireless Ethernet networks are access point 
    and peer-to-peer. Network Type Speed Frequency Advantages Disadvantages
    IEEE 802.11a 54 Mbps 5 GHz Less possible 
    interference than 
    IEEE 802.11b and 
    IEEE 802.11g■Shorter range (25 to 
    75 feet) than 
    IEEE 802.11b and 
    IEEE 802.11g
    ■Not compatible with 
    IEEE 802.11b or 
    IEEE 802.11g 
    networks
    IEEE 802.11b 11 Mbps 2.4 GHz
    ■Large number of 
    access points already 
    exist in airports, 
    college campuses, and 
    businesses
    ■Compatible with 
    IEEE 802.11g 
    networks
    ■Longer range (100 to 
    150 feet) than 
    IEEE 802.11a
    ■Possible interference 
    from cordless phones 
    and microwaves
    ■Not compatible with 
    IEEE 802.11a 
    networks
    IEEE 802.11g 54 Mbps 2.4 GHz
    ■Compatible with 
    IEEE 802.11b 
    networks
    ■Longer range (100 to 
    150 feet) than 
    IEEE 802.11a
    ■Possible interference 
    from cordless phones 
    and microwaves
    ■Not compatible with 
    IEEE 802.11a 
    networks
    ImportantThe speed of a wireless network is related to signal 
    strength. Signal strength is affected by the distance 
    between your wireless network devices, by radio 
    interference, and by interference from natural obstructions 
    such as walls, floors, and doors.

    Example access point wireless Ethernet 
    network
    By using an access point, you can join a wireless Ethernet network and access 
    a wired Ethernet network. The following example shows how an access point 
    also lets you access the Internet.
    The following is an example of an access point wireless Ethernet network. The 
    network is made up of an access point, a cable or DSL modem, and your 
    computers. The access point is the central control point for the network. 
    Attached to the access point is the cable or DSL modem that provides access 
    to the Internet. Each of the computers or Ethernet-ready devices communicate 
    with the access point using radio waves. If your computer does not have built-in 
    wireless Ethernet capabilities, you need to add a wireless PCI card (desktop), 
    PC card (notebook or convertible tablet PC), or USB adapter.
    Tips & TricksIf you want to access a wireless Ethernet network from 
    your wired Ethernet network, connect an access point to 
    the router, switch, or hub. For more information about 
    accessing a wired Ethernet, see “Using a wired Ethernet 
    network” on page 201.

    Equipment you need for an access point 
    wireless Ethernet network
    For an access point wireless Ethernet network you need:
    ■A wireless Ethernet PCI card installed in each desktop computer
    - OR -
    A wireless Ethernet USB adapter attached to each desktop or notebook 
    computer, or convertible tablet PC
    - OR -
    A notebook, tablet PC, or convertible tablet PC with wireless Ethernet 
    built-in
    - OR -
    A wireless Ethernet PC Card installed in each notebook or convertible 
    tablet PC that does not have wireless Ethernet built-in
    ■A wireless Ethernet access point to connect your wireless Ethernet network 
    to the Internet or a wired Ethernet network
    ImportantIEEE 802.11b and IEEE 802.11g use the same radio 
    frequency. IEEE 802.11a uses a different radio frequency 
    than IEEE 802.11b and IEEE 802.11g. All wireless 
    Ethernet components must use the same frequency. A 
    combination of IEEE 802.11a and IEEE 802.11b or 
    IEEE 802.11a and IEEE 802.11g components will 
    not work. Some wireless devices can broadcast and 
    receive signals on both frequencies.
    A mixture of IEEE 802.11b and IEEE 802.11g components 
    will result in your network running at the speed of the 
    slower IEEE 802.11b components.

    Example peer-to-peer wireless Ethernet 
    network
    Use a peer-to-peer (also known as ad hoc) wireless Ethernet network if you are 
    setting up or joining a temporary computer-to-computer network. This type of 
    network does not include access into a wired network or the Internet. You can 
    create this type of network to quickly move files from one computer to another.
