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. Turn on the computer.

2. Be sure that the WLAN device is on.

NOTE: Refer to Using the action keys on page 19 for information on identifying the location

of the wireless key on your computer.

3. Click the Network Connection icon in the notification area, at the far right of the taskbar.

Available wireless networks are listed under Wireless Networks.

4. 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 a 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

Connecting to a local area network (LAN) (select models only)

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) 17

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.

60 Chapter 10 Security

Using firewall software

Firewalls are designed to prevent unauthorized access to a system or network. A firewall can be a software program you install on your computer and/or network, or it can be a solution made up of both hardware and software.

There are two types of firewalls to consider:

Host-based firewalls—Software that protects only the computer it is installed on.

●

Network-based firewalls—Installed between your DSL or cable modem and your home network

●

to protect all the computers on the network.

When a firewall is installed on a system, all data sent to and from the system is monitored and compared with a set of user-defined security criteria. Any data that does not meet those criteria is blocked.

Your computer or networking equipment may already have a firewall installed. If not, firewall software solutions are available.

NOTE: Under some circumstances a firewall can block access to Internet games, interfere with

printer or file sharing on a network, or block authorized e-mail attachments. To temporarily resolve the problem, disable the firewall, perform the task that you want to perform, and then reenable the firewall. To permanently resolve the problem, reconfigure the firewall.

Using firewall software 61

Installing an optional security cable

NOTE: A security cable is designed to act as a deterrent, but it may not prevent the computer from

being mishandled or stolen.

NOTE: The security cable slot on your computer may look different from the illustration in this

section. Refer to on your computer.

1. Loop the security cable around a secured object.

2. Insert the key (1) into the cable lock (2).

3. Insert the cable lock into the security cable slot on the computer (3), and then lock the cable lock

with the key.
