2 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 Bluetoothenabled 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.

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.
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)
Connecting to a wireless network 5
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.
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 to 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 Using firewall software on page 38 .
●
Use wireless encryption.
Wireless encryption uses security settings to encrypt and decrypt data that is transmitted over the network.
6 Chapter 2 Connecting to a network

Security cable locks are only one of several methods that should be employed as part of a complete security solution to help maximize theft protection.
The security cable slot on your computer may look slightly different from the illustration in this section.
1.
Loop the security cable lock around a secured object.
2.
Insert the key (1) into the security cable lock (2).
3.
Insert the security cable lock into the security cable slot on the computer (3), and then lock the security cable lock with the key.
4.
Remove the key and keep it in a safe place.

10 Backing up, restoring, and recovering
Recovery after a system failure is as good as your most recent backup. As you add new software and data files, you should continue to back up your system on a regular basis to maintain a reasonably current backup.
Performing a system recovery
The Deja Dup Restore Tool allows you to repair or restore the computer to its original factory state.
You can create an image restore DVD using a DVD±RW optical drive. You can also create a restore image on a USB storage device.
CAUTION:
Using Restore completely erases hard drive contents and reformats the hard drive. All files you have created and any software installed on the computer are permanently removed. The recovery tool reinstalls the original operating system and programs and drivers that were installed at the factory. Software, drivers, and updates not installed at the factory must be manually reinstalled.
Personal files must be restored from a backup.
NOTE:
HP recommends that you create the image restore in the event of a system failure.
Creating the restore DVDs
The restore creation software creates a set of system restore discs using blank, writable DVDs (DVD-
R or DVD+R). HP recommends using blank DVD+R discs from a manufacturer you trust, because these recovery DVDs are so important. You need approximately 3 blank DVD+R discs. The program states how many discs are needed at the beginning of the process.
To create restore DVDs:
1.
Click the System menu icon at the far right of the top panel, and then click System Settings >
Backup.
2.
Select Storage from the panel on the left side of the window, click the down-arrow next to
Backup Location, and select the DVD from the drop-down list.

Select Overview from the panel on the left side of the window, and then click Back Up Now.
4.
Follow the on-screen instructions.
Creating a restore image on a USB device
NOTE:
Be sure AC power is connected to the computer you begin.
Verify the exact amount of free space on your storage device before you begin the creation process.
For most models, you will need at least 8 GB of free space on the storage device. However, depending on the drivers and software installed on your computer, you may need slightly more than 8
GB of space. HP recommends that you use a 16 GB device or above for best results.
IMPORTANT:
Remember to insert your USB device into the USB port on the computer before starting this procedure.

13 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.
