3Networking

Your computer supports the following types of Internet access:

● Wireless—For mobile Internet access, you can use a wireless connection. See

existing WLAN on page 12 or Setting up a new WLAN on page 13.

● Wired—You can access the Internet by connecting to a wired network. For information on

connecting to a wired network, see

NOTE: Internet hardware and software features vary depending on computer model and your

location.

Connecting to a wired network on page 15.

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 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.

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

prompted for the root password.

Connecting to an existing WLAN

1. Turn on the computer.

2. Be sure that the WLAN device is on.

NOTE: See Getting to know your computer on page 3 for information on identifying the location

of the wireless light on your computer, and see information on identifying the location of the wireless key.

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.

Using the action keys on page 16 for

NOTE: If no WLANs are listed, and your network is not hidden, you are out of range of a

wireless router or access point.

12 Chapter 3 Networking

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, click Edit Connections, and then click the

Wireless tab.

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.

For help in setting up your WLAN, see 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 email that is not confidential and basic Internet surfing.

Using a WLAN 13

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:

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.

To access the built-in firewall, select Computer > YaST > Security and Users > Firewall, and then follow the on-screen instructions.

Wireless encryption—Your computer supports three encryption protocols:

●

Wi-Fi Protected Access (WPA)

◦

Wi-Fi Protected Access II (WPA2)

◦

Wired Equivalent Privacy (WEP)

◦

NOTE: HP recommends that you select WPA2, which is the most advanced of the three encryption

protocols. The use of WEP encryption is not recommended, because it can be overcome with little effort.

● Wi-Fi Protected Access (WPA) and Wi-Fi Protected Access II (WPA2) use security standards to

encrypt and decrypt data transmitted over the network. Both WPA and WPA2 dynamically generate a new key for every packet, and they also generate a different set of keys for each computer on the network. To accomplish this:

WPA uses Advanced Encryption Standard (AES) and Temporal Key Integrity Protocol

◦

(TKIP).

◦ WPA2 uses Cipher Block Chaining Message Authentication Code Protocol (CCMP), which

is a new AES protocol.

Wired Equivalent Privacy (WEP) encrypts data with a WEP key before it is transmitted. 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.

Using Bluetooth wireless devices

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.

14 Chapter 3 Networking

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, see the Bluetooth software Help.

Connecting to a wired network

Connecting to a local area network (LAN)

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.

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.

2. Plug the other end of the cable into a network wall jack (2) or a router (not illustrated).

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 email 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.

1. To view or modify the firewall settings, select Computer > YaST.

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

2. In the left pane, click Security and Users, and then click Firewall in the right pane.

11 Backup and Recovery

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

Recovery allows you to repair or restore the computer to its original factory state. You can create an HP factory image restore DVD, using an external DVD±RW optical drive. You can also create an HP factory restore image on a USB storage device.

CAUTION: Using Recovery 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 HP programs and drivers that were installed at the factory. Software, drivers, and updates not installed by HP must be manually reinstalled. Personal files must be restored from a backup.

NOTE: HP recommends that you create the HP factory 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 (DVDR 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. Select Computer > More Applications.

2. In the left pane, click Tools, and then click Create Restore DVD in the right pane.

3. Follow the on-screen instructions to create an image file to burn a recovery disc.

Creating a restore image on a USB device

NOTE: Be sure AC power is connected to the computer you begin.

17 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.
