Using wireless devices

Wireless technology transfers data across radio waves instead of wires. The computer might 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, each mobile wireless device communicates with a wireless router or a wireless access point.

Bluetooth device (select models only)—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.

Computers with WLAN devices support one or more of the following IEEE industry standards:

802.11b, the first popular standard, supports data rates of up to 11 Mbps and operates at a

●

frequency of 2.4 GHz.

802.11g supports data rates of up to 54 Mbps and operates at a frequency of 2.4 GHz. An 802.11g

●

WLAN device is backward compatible with 802.11b devices, so that they can operate on the same network.

802.11a supports data rates of up to 54 Mbps and operates at a frequency of 5 GHz.

●

NOTE: 802.11a is not compatible with 802.11b and 802.11g.

802.11n supports data rates of up to 450 Mbps and might operate at 2.4 GHz or 5 GHz, making it

●

backward compatible with 802.11a, b, and g.

Using the wireless key

The computer has a wireless key, one or more wireless devices, and one or two wireless lights, depending on the model. All of the wireless devices on the computer are enabled at the factory, so the wireless light illuminates 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 illuminates white, at least one wireless device is on. If the wireless light illuminates amber, all wireless devices are off.

Because the wireless devices are enabled at the factory, use the wireless key to turn on or turn off the wireless devices simultaneously. Individual wireless devices are controlled through HP Wireless Assistant.

14 Chapter 2 Wireless, local area network, and modem

Using HP Wireless Assistant

A wireless device is turned on or off using HP Wireless Assistant. If a wireless device is disabled by Setup Utility, it must be re-enabled by Setup Utility before it can be turned on or off using Wireless Assistant.

NOTE: Enabling or turning on a wireless device does not automatically connect the computer to a

network or a Bluetooth-enabled device.

To view the state of the wireless devices, click the Show hidden icons icon, the arrow at the left of the notification area, and position the mouse pointer over the wireless icon.

If the wireless icon is not displayed in the notification area:

1. Select Start > Control Panel > Hardware and Sound > Windows Mobility Center.

2. Click the Wireless icon in the Wireless Assistant tile, which is located in the bottom row of Windows

Mobility Center. Wireless Assistant appears.

3. Click Properties.

4. Select the check box next to HP Wireless Assistant icon in notification area.

5. Click Apply.

6. Click Close.

For more information, see the Wireless Assistant software Help. To access Help:

1. Open Wireless Assistant by clicking the Wireless icon in Windows Mobility Center.

2. Click the Help button.

Using operating system controls

Some operating systems offer a way to manage integrated wireless devices and the wireless connection. For example, Windows provides the Network and Sharing Center that allows you to set up a connection or network, connect to a network, manage wireless networks, and diagnose and repair network problems.

To access the Network and Sharing Center, select Start > Control Panel > Network and Internet > Network and Sharing Center.

For more information, select Start > Help and Support.

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.

Using a WLAN 15

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

A home or small office WLAN 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 the computer, connect to a WLAN infrastructure (provided through a service provider or a public or corporate network).

Setting up a WLAN

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

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.

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

Because the WLAN standard was designed with only limited security capabilities—basically to foil casual eavesdropping rather than more powerful forms of attack—it is essential to understand that WLANs are vulnerable to well-known and well-documented security weaknesses.

WLANs in public areas, or “hotspots,” like coffee shops and airports might not provide any security. New technologies are being developed by wireless manufacturers and hotspot service providers that make the public environment more secure and anonymous. If you are concerned about the security of the computer in a hotspot, limit your network activities to noncritical e-mail and basic Internet surfing.

When setting up a WLAN or access an existing WLAN, always enable security features to protect your network from unauthorized access. The common security levels are Wi-Fi Protected Access (WPA)Personal and Wired Equivalent Privacy (WEP). Because wireless radio signals travel outside the

network, other WLAN devices can pick up unprotected signals and either connect to your network (uninvited) or capture information being sent across it. To protect the WLAN:

Use a wireless transmitter with built-in security

●

Many wireless base stations, gateways, or routers provide built-in security features such as wireless security protocols and firewalls. With the correct wireless transmitter, you can protect your network from the most common wireless security risks.

Work behind a firewall

●

A firewall is a barrier that checks both data and requests that are sent to the network, and discards any suspicious items. Firewalls are available in many varieties, both software and hardware. Some networks use a combination of both types.

Use wireless encryption

●

A variety of sophisticated encryption protocols is available for your WLAN. Find the solution that works best for your network security:

Wired Equivalent Privacy (WEP) is a wireless security protocol that encodes or encrypts all

◦

network data before it is transmitted using a WEP key. The network assigns the WEP key, but you can set up your own key, generate a different key, or choose other advanced options. Without the correct key, others cannot access the WLAN.

WPA (Wi-Fi Protected Access), like WEP, uses security settings to encrypt and decrypt data

◦

that is transmitted over the network. However, instead of using one static security key for encryptions as WEP does, 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.

Connecting to a WLAN

To connect to the WLAN:

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

light is off, press the wireless key.

NOTE: On some models, the wireless light is amber when all wireless devices are off.

2. Click the Network icon in the notification area at the far right of the taskbar.

3. Select your WLAN from the list.

4. Click Connect.

NOTE: If no WLANs are listed, you are out of range of a wireless router or access point.

If the network is a security-enabled WLAN, enter a network security key at the prompt, which

●

is a security code, and then click OK to complete the connection.

If you do not see the network you want to connect to, click Open Network and Sharing

●

Center, and then click Set up a new connection or network. A list of options appears. Search for and connect to a network or to create a new network connection.

After the connection is made, place the mouse pointer over the Network icon in the notification area to verify the name and status of the connection.

Using a WLAN 17

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.

More information about using a WLAN is available through:

Your ISP and the user guides included with the wireless router and other WLAN equipment

●

Help and Support information and website links

●

For a list of public WLANs near you, contact your ISP or search the Web. Websites that list public WLANs include Cisco Internet Mobile Office Wireless Locations, Hotspotlist, and Geektools. Check with each public WLAN location for cost and connection requirements.

Roaming to another network

When you move the computer within range of another WLAN, Windows attempts to connect to that network. If the attempt is successful, the computer is automatically connected to the new network. If Windows does not recognize the new network, follow the instructions in “Connecting to a WLAN.”

18 Chapter 2 Wireless, local area network, and modem

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:

Computers (desktop, notebook, PDA)

●

Phones (cellular, cordless, smart phone)

●

Imaging devices (printer, camera)

●

Audio devices (headset, speakers)

●

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.

Bluetooth and Internet Connection Sharing (ICS)

HP does not recommend setting up a host, Bluetooth computer and using it as a gateway through which other computers connect to the Internet. When two or more computers are connected using Bluetooth, and Internet Connection Sharing (ICS) is enabled on one of the computers, the other computers cannot connect to the Internet using the Bluetooth network.

The strength of Bluetooth is in synchronizing information transfers between the computer and wireless devices including cellular phones, printers, cameras, and PDAs. The inability to consistently connect two or more computers to share the Internet through Bluetooth is a limitation of Bluetooth and the Windows operating system.

Using Bluetooth wireless devices (select models only) 19

Connecting to a local area network

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.

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

modem or telephone cable to the RJ-45 (network) jack.

To connect the network cable:

1. Connect the network cable to the network jack (1) on the computer.

2. Connect the other end of the cable to a network wall jack (2).
