Safety warning notice
WARNING! To reduce the possibility of heat-related injuries or of overheating the computer, do not
place the computer directly on your lap or obstruct the computer air vents. Use the computer only on
a hard, flat surface. Do not allow another hard surface, such as an adjoining optional printer, or a soft
surface, such as pillows or rugs or clothing, to block airflow. Also, do not allow the AC adapter to
come into contact with the skin or a soft surface, such as pillows or rugs or clothing, during operation.
The computer and the AC adapter comply with the user-accessible surface temperature limits defined
by the International Standard for Safety of Information Technology Equipment (IEC 60950).

Using an Internet service provider (ISP)
Before you can connect to the Internet, you must establish an ISP account. Contact a local ISP to
purchase Internet service and a modem. The ISP can help set up the modem, install a network cable
to connect your wireless computer to the modem, and test the Internet service.
NOTE: Your ISP will give you a user ID and password to access the Internet. Record this
information and store it in a safe place.

Using the wireless button
Use the wireless button to turn both the wireless network controller and the Bluetooth controller off or
on simultaneously. They can be controlled individually through the Control Center or Computer Setup.
NOTE: Refer to Getting to know your computer on page 3 for information on identifying the location
of the wireless button on your computer.
Indicates that the wired network is connected and active. If both
wired and wireless connections are active, the operating system
uses the wired connection because it is faster.
Indicates that wired and wireless networks are not connected.
Using the operating system controls
To enable or disable a wireless or wired network device:
1. Right-click the Network Connection icon in the notification area, at the far right of the taskbar.
2. To enable or disable one of the following devices, select or clear one of the following options:
Enable Networking (all network devices)
●
Enable Wireless
●
Using a WLAN
A wireless connection connects the computer to Wi-Fi networks, or WLANs. A WLAN is composed of
other computers and accessories that are linked by a wireless router or a wireless access point.
14 Chapter 3 Networking
Connecting to an existing WLAN
1. Be sure that the WLAN device is on.
NOTE: Refer to Getting to know your computer on page 3 for information on identifying the
location of the wireless button and wireless light on your computer.
2. Click the Network Connection icon in the notification area, at the far right of the taskbar.
Available wireless networks are listed under Wireless Networks.
3. Click the desired wireless network.
If the network is a security-enabled WLAN, you are prompted to enter a network security code.
Type the code, and then click OK to complete the connection.
NOTE: To connect to a network that is not automatically detected, click the Network
Connection icon and select Connect to Hidden Wireless Network. Enter the ESSID
information, and set encryption parameters.
NOTE: If no WLANs are listed, and your network is not hidden, you are out of range of a
wireless router or access point.
If you do not see the network you want to connect to, right-click the Network Connection icon in
the notification area, at the far right of the taskbar, and click Edit Connections.
Setting up a new WLAN
Required equipment:
A broadband modem (either DSL or cable) (1) and high-speed Internet service purchased from
●
an Internet service provider (ISP)
A wireless router (purchased separately) (2)
●
The wireless computer (3)
●
The illustration below shows an example of a wireless network installation that is connected to the
Internet.
NOTE: Some cable modems include a built-in router. Check with your ISP to see if you need a
separate router.
NOTE: When setting up a wireless connection, be sure that your computer and wireless router are
synchronized. To synchronize your computer and wireless router, turn your computer and wireless
router off and then back on.
As your network grows, additional wireless and wired computers can be connected to the network to
access the Internet.
Using a WLAN 15
For help in setting up your WLAN, refer to the information provided by your router manufacturer or
your ISP.
Protecting your WLAN
When you set up a WLAN or access an existing WLAN, always enable security features to protect
your network from unauthorized access. WLANs in public areas (hotspots) like coffee shops and
airports may not provide any security. If you are concerned about the security of your computer in a
hotspot, limit your network activities to e-mail that is not confidential and basic Internet surfing.
Wireless radio signals travel outside the network, so other WLAN devices can pick up unprotected
signals. You can use the following precautions to protect your WLAN:
Use Firewall—Checks both data and requests for data that are sent to your network, and
●
discards any suspicious items. Firewalls are available in both software and hardware. Some
networks use a combination of both types.
Encrypt your data—Wi-Fi Protected Access (WPA and WPA2) encrypts and decrypts data
●
transmitted over the network. WPA uses Temporal Key Integrity Protocol (TKIP) to dynamically
generate a new key for every packet. It also generates different sets of keys for each computer
on the network. Wired Equivalent Privacy (WEP) encrypts data before it is transmitted using a
WEP key. Without the correct key, others will not be able to use the WLAN.
Roaming to another network
When you move your computer within range of another WLAN, the operating system attempts to
connect to that network. If the attempt is successful, your computer is automatically connected to the
new network. If the operating system does not recognize the new network, follow the same procedure
you used initially to connect to your WLAN.
16 Chapter 3 Networking
Using Bluetooth wireless devices (select models only)
A Bluetooth device provides short-range wireless communications that replace the physical cable
connections that traditionally link electronic devices such as the following:
Computers
●
Phones
●
Audio devices
●
The strength of Bluetooth is in synchronizing information transfers between your computer and
wireless devices. The inability to consistently connect two or more computers to share the Internet
through Bluetooth is a limitation of Bluetooth and the operating system.
Bluetooth devices provide peer-to-peer capability that allows you to set up a personal area network
(PAN) of Bluetooth devices. For information on configuring and using Bluetooth devices, refer to the
Bluetooth software Help.
Connecting to a wired network
Using a modem (select models only)
A modem must be connected to an analog telephone line using a 6-pin, RJ-11 modem cable
(purchased separately). In some countries or regions, a specific modem cable adapter is also
required. Jacks for digital PBX systems may resemble analog telephone jacks, but they are not
compatible with the modem.
WARNING! To reduce the risk of electric shock, fire, or damage to the equipment, do not plug a
modem or telephone cable into the RJ-45 (network) jack.
If the modem cable contains noise suppression circuitry (1), which prevents interference from TV and
radio reception, orient the circuitry end of the cable (2) toward the computer.
Connecting a modem cable
1. Plug the modem cable into the modem jack (1) on the computer.
Using Bluetooth wireless devices (select models only) 17
2. Plug the modem cable into the RJ-11 telephone wall jack (2).
Connecting a country- or region-specific modem cable adapter
Telephone jacks vary by country or region. To use the modem and the modem cable outside the
country or region in which you purchased the computer, you must obtain a country- or region-specific
modem cable adapter.
To connect the modem to an analog telephone line that does not have an RJ-11 telephone jack,
follow these steps:
1. Plug the modem cable into the modem jack (1) on the computer.
2. Plug the modem cable into the modem cable adapter (2).
3. Plug the modem cable adapter (3) into the telephone wall jack.
