24 Chapter 3 Networking

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, 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.

Wireless encryption—Your computer supports three encryption protocols:

●

◦ Wi-Fi Protected Access (WPA)

Wi-Fi Protected Access II (WPA2)

◦

Wired Equivalent Privacy (WEP)

◦

Using a WLAN 25

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.

26 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) 27

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

13 MultiBoot

About the boot device order

As the computer starts, the system attempts to boot from enabled boot devices. The MultiBoot utility, which is enabled at the factory, controls the order in which the system selects a boot device. Boot devices can include optical drives, diskette drives, a network interface card (NIC), hard drives, and USB devices. Boot devices contain bootable media or files that the computer needs to start and operate properly.

NOTE: Some boot devices must be enabled in Computer Setup before they can be included in the

boot order.

The factory setting is for the computer to select the boot device by searching enabled boot devices and drive bay locations in the following order:

NOTE: Some of the boot devices and drive bay locations listed may not be supported on your

computer.

Notebook upgrade bay

●

Optical drive

●

● Notebook hard drive

● USB diskette drive

USB CD-ROM

●

USB hard drive

●

Notebook Ethernet

●

Secure Digital (SD) Memory Card

●

● Docking station upgrade bay

● External SATA drive

You can change the order in which the computer searches for a boot device by changing the boot order in Computer Setup. You can also press esc while the “Press the ESC key for Startup Menu” message is displayed at the bottom of the screen, and then press f9. Pressing f9 displays a menu that shows the current boot devices and allows you to select a boot device. Or, you can use MultiBoot Express to set the computer to prompt you for a boot location each time the computer turns on or restarts.

About the boot device order 81

Enabling boot devices in Computer Setup

82 Chapter 13 MultiBoot

Considering boot order changes

Before changing the boot order, note the following considerations:

When the computer restarts after the boot order has been changed, the computer attempts to

●

start using the new boot order.

If there is more than one type of boot device, the computer attempts to boot using the first device

●

of each type of boot device (except for optical devices). For example, if the computer is connected to an optional docking device (select models only) that contains a hard drive, this hard drive will be shown in the boot order as a USB hard drive. If the system attempts to boot from this USB hard drive and fails, it will not attempt to boot to the hard drive in the hard drive bay. Instead, it will try to boot to the next type of device in the boot order. However, if there are two optical devices, and the first optical device does not boot (either because it does not contain media or the media is not a boot disc), the system will try to boot to the second optical device.

Changing the boot order also changes the logical drive designations. For example, if you start up

●

from a CD-ROM drive with a disc formatted as drive C, that CD-ROM drive becomes drive C and the hard drive in the hard drive bay becomes drive D.

The computer will boot from a NIC device only if the device has been enabled in the Built-In

●

Device Options menu of Computer Setup and if booting from the device has been enabled in the Boot Options menu of Computer Setup. Booting from a NIC does not affect logical drive designations because no drive letter is associated with the NIC.

Drives in an optional docking device (select models only) are treated like external USB devices

●

in the boot order.

Considering boot order changes 83
