14 Chapter 2 Getting to know your computer

3 Connecting to a network

Your computer can travel with you wherever you go. But even at home, you can explore the globe and access information from millions of websites using your computer and a wired or wireless network connection. This chapter will help you get connected to that world.

Connecting to a wireless network

Wireless technology transfers data across radio waves instead of wires. Your computer may be equipped with one or more of the following wireless devices:

Wireless local area network (WLAN) device—Connects the computer to wireless local area

●

networks (commonly referred to as Wi-Fi networks, wireless LANs, or WLANs) in corporate offices, your home, and public places such as airports, restaurants, coffee shops, hotels, and universities. In a WLAN, the mobile wireless device in your computer communicates with a wireless router or a wireless access point.

● Bluetooth device—Creates a personal area network (PAN) to connect to other Bluetooth-

enabled devices, such as computers, phones, printers, headsets, speakers, and cameras. In a PAN, each device communicates directly with other devices, and devices must be relatively close together—typically within 10 meters (approximately 33 feet) of each other.

Identifying wireless and network status icons

Icon Name Description

Wireless (connected) Indicates that one or more wireless devices are on.

Network Connection (connected)

Network Connection (disconnected)

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 wireless controls

You can control the wireless devices in your computer using these features:

● Wireless button, wireless switch, or wireless key (referred to in this chapter as the wireless

button)

Operating system controls

●

Connecting to a wireless network 15

Using the wireless button

The computer has a wireless button, one or more wireless devices, and a wireless light, depending on the model. All of the wireless devices on your computer are enabled at the factory, so the wireless light is on (white) when you turn on the computer.

The wireless light indicates the overall power state of your wireless devices, not the status of individual devices. If the wireless light is white, at least one wireless device is on. If the wireless light is amber, all wireless devices are off.

Because the wireless devices are enabled at the factory, you can use the wireless button to turn on or turn off the wireless devices simultaneously. Individual wireless devices can be controlled by clicking on the Network menu icon at the far right of the top panel, and then clicking Edit Connections.

Using operating system controls

To enable or disable a wireless or wired network device:

1. Click the Network menu icon at the far right of the top panel.

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

With a WLAN device, you can access a wireless local area network (WLAN), which is composed of other computers and accessories that are linked by a wireless router or a wireless access point.

NOTE: When creating a wireless connection or allowing access to users in a network, you are

prompted for the root password.

NOTE: The terms wireless router and wireless access point are often used interchangeably.

A large-scale WLAN, such as a corporate or public WLAN, typically uses wireless access points

●

that can accommodate a large number of computers and accessories and can separate critical network functions.

A home or small office WLAN typically uses a wireless router, which allows several wireless and

●

wired computers to share an Internet connection, a printer, and files without requiring additional pieces of hardware or software.

To use the WLAN device in your computer, you must connect to a WLAN infrastructure (provided through a service provider or a public or corporate network).

Using an Internet service provider

When you are setting up Internet access in your home, you must establish an account with an Internet service provider (ISP). To purchase Internet service and a modem, contact a local ISP. The ISP will 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 a password to use for Internet access. Record this

information and store it in a safe place.

16 Chapter 3 Connecting to a network

Setting up a WLAN

To set up a WLAN and connect to the Internet, you need the following equipment:

A broadband modem (either DSL or cable) (1) and high-speed Internet service purchased from

●

an Internet service provider

A wireless router (2) (purchased separately)

●

A wireless computer (3)

●

NOTE: Some modems have a built-in wireless router. Check with your ISP to determine what type

of modem you have.

The illustration below shows an example of a wireless network installation that is connected to the Internet.

As your network grows, additional wireless and wired computers can be connected to the network to access the Internet.

For help in setting up your WLAN, see the information provided by your router manufacturer or your ISP.

Configuring a wireless router

For help in setting up a WLAN, see the information provided by your router manufacturer or your ISP.

NOTE: It is recommended that you initially connect your new wireless computer to the router by

using the network cable provided with the router. When the computer successfully connects to the Internet, disconnect the cable, and access the Internet through your wireless network.

Connecting to a wireless network 17

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 email that is not confidential and basic Internet surfing.

Wireless radio signals travel outside the network, so other WLAN devices can pick up unprotected signals. Take the following precautions to protect your WLAN:

Use a firewall.

●

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. Ubuntu does not include firewall software, but you can download Gufw, a free firewall utility that Ubuntu provides. For information on how to download and install Gufw, refer to

Use wireless encryption.

●

Wireless encryption uses security settings to encrypt and decrypt data that is transmitted over the network.

Connecting to a WLAN

To connect to the WLAN, follow these steps:

Using firewall software on page 55.

1. Be sure that the WLAN device is on. If the device is on, the wireless light is white. If the wireless

light is amber, press the wireless button.

2. Click the Network menu icon at the far right of the top panel.

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 menu

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, click the Network menu icon at the far right of the top panel, and click Edit Connections.

NOTE: The functional range (how far your wireless signals travel) depends on WLAN

implementation, router manufacturer, and interference from other electronic devices or structural barriers such as walls and floors.

18 Chapter 3 Connecting to a network

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 (desktop, notebook, PDA)

●

● Phones (cellular, cordless, smart phone)

● Imaging devices (printer, camera)

Audio devices (headset, speakers)

●

Mouse

●

Bluetooth devices provide peer-to-peer capability that allows you to set up a personal area network (PAN) of Bluetooth devices. For information about configuring and using Bluetooth devices, see the Bluetooth software Help.

Connecting to a wireless network 19

Connecting to a wired network

A LAN connection uses a network cable, which is sold separately.

WARNING! To reduce the risk of electric shock, fire, or damage to the equipment, do not plug a

modem cable or telephone cable into an RJ-45 (network) jack.

Connecting to a local area network (LAN)

Use a LAN connection if you want to connect the computer directly to a router in your home (instead of working wirelessly), or if you want to connect to an existing network at your office.

Connecting to a LAN requires an 8-pin, RJ-45 network cable.

50 Chapter 8 Maintaining your computer

Traveling with or shipping your computer

If you have to travel with or ship your computer, here are some tips to keep in mind to keep your equipment safe.

Prepare the computer for traveling or shipping:

●

Back up your information to an external drive.

◦

Remove all discs and all external media cards, such as digital storage cards, from the

◦

computer.

Turn off, and then disconnect all external devices.

◦

Remove any media from the drive before removing the drive from a drive bay.

◦

CAUTION: Perform this action before shipping, storing, or traveling with a drive. This will

help reduce the risk of damage to the computer, damage to a drive, or loss of information.

Shut down the computer.

◦

Take along a backup of your information. Keep the backup separate from the computer.

●

When traveling by air, carry the computer as hand luggage; do not check it in with the rest of

●

your luggage.

CAUTION: Avoid exposing a drive to magnetic fields. Security devices with magnetic fields

include airport walk-through devices and security wands. Airport conveyer belts and similar security devices that check carry-on baggage use X-rays instead of magnetism and do not damage drives.

● If you plan to use the computer during a flight, listen for the in-flight announcement that tells you

when you are allowed to use your computer. In-flight computer use is at the discretion of the airline.

If the computer will be unused and disconnected from external power for more than 2 weeks,

●

remove the battery and store it separately.

If you are shipping the computer or a drive, use suitable protective packaging and label the

●

package “FRAGILE.”

● If the computer has a wireless device installed, the use of these devices may be restricted in

some environments. Such restrictions may apply onboard aircraft, in hospitals, near explosives, and in hazardous locations. If you are uncertain of the policy that applies to the use of a particular device, ask for authorization to use your computer before you turn it on.

If you are traveling internationally, follow these suggestions:

●

Check the computer-related customs regulations for each country or region on your

◦

itinerary.

Check the power cord and adapter requirements for each location in which you plan to use

◦

the computer. Voltage, frequency, and plug configurations vary.

WARNING! To reduce the risk of electric shock, fire, or damage to the equipment, do not

attempt to power the computer with a voltage converter kit sold for appliances.

Using Internet security software

When you use your computer to access email, a network, or the Internet, you potentially expose your computer to computer viruses, spyware, and other online threats. To help protect your computer, Internet security software that includes antivirus and firewall features may be preinstalled on your computer as a trial offer. To provide ongoing protection against newly discovered viruses and other security risks, security software must be kept up to date. It is strongly recommended that you upgrade the security software trial offer or purchase the software of your choice in order to fully protect your computer.

Using antivirus software

Computer viruses can disable programs, utilities, or the operating system, or cause them to function abnormally. Antivirus software can detect most viruses, destroy them, and in most cases, repair any damage they have caused.

Using firewall software

Firewalls are designed to prevent unauthorized access to a system or network. The Ubuntu operating system ships with no open ports; therefore, it does not include a firewall utility in the base operating system. However, you may use the Ubuntu Software Center, located in the Launcher on the left side of the desktop, to download Gufw, a free Ubuntu firewall utility.

To install Gufw:

1. Click on the Ubuntu Software Center folder located in the Launcher on the left side of the

desktop.

2. Enter Gufw in the search bar and press enter.

3. Double-click the Firewall Configuration icon, and then click the Install button.

4. Follow the on-screen instructions.

To view or modify firewall settings after installing Gufw:

1. Select Ubuntu Software Center from the Launcher on the left side of the desktop, and then

click Gufw.

NOTE: When accessing Gufw, you are prompted for the root password.

2. Follow the on-screen instructions.

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

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

Using Internet security software 55

Securing your wireless network

Troubleshooting an AC adapter

Test the AC adapter if the computer exhibits any of the following symptoms when it is connected to AC power:

The computer does not turn on.

●

The display does not turn on.

●

The power lights are off.

●

To test the AC adapter:

1. Shut down the computer.

2. Remove the battery from the computer.

3. Connect the AC adapter to the computer, and then plug it into an AC outlet.

4. Turn on the computer.

If the power lights turn on, the AC adapter is working properly.

●

If the power lights remain off, check the connection from the AC adapter to the computer

●

and the connection from the AC adapter to the AC outlet to make sure the connections are secure.

If the connections are secure and the power lights remain off, the AC adapter is not

●

functioning and should be replaced.

14 Electrostatic 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 support.
