16Chapter 3 Networking
Page 25
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 correct 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 WLAN17
Page 26
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 take the following precautions to protect your WLAN:
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.
Wireless encryption—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.
18Chapter 3 Networking
Page 27
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 local area network (LAN)
Connecting to a local area network (LAN) requires an 8-pin, RJ-45 network cable (purchased
separately). If the network 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.
To connect the network cable:
1.Plug the network cable into the network jack (1) on the computer.
Using Bluetooth wireless devices (select models only)19
Page 28
2.Plug the other end of the cable into a network wall jack (2).
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.

DElectrostatic discharge
Electrostatic discharge is the release of static electricity when two objects come into contact—for
example, the shock you receive when you walk across the carpet and touch a metal door knob.
A discharge of static electricity from fingers or other electrostatic conductors may damage electronic
components. To prevent damage to the computer, damage to a drive, or loss of information, observe
these precautions:
If removal or installation instructions direct you to unplug the computer, unplug it after being properly
●
grounded and before removing a cover.
Keep components in their electrostatic-safe containers until you are ready to install them.
●
Avoid touching pins, leads, and circuitry. Handle electronic components as little as possible.
●
Use nonmagnetic tools.
●
Before handling components, discharge static electricity by touching an unpainted metal surface
●
of the component.
If you remove a component, place it in an electrostatic-safe container.
●
If you need more information about static electricity or assistance with component removal or installation,
contact Customer Support.
