Using wireless devices (select models only)

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

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—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 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 may operate at 2.4 GHz or 5 GHz, making it

Using a WLAN

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

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).

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 (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, refer to 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, may 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 your computer in a hotspot, limit your network activities to noncritical e-mail and basic Internet surfing.

18 Chapter 2 Networking

When you set 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) 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. However, you can take precautions to protect your WLAN:

● Use a wireless transmitter with built-in security

Many wireless base stations, gateways, and 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 for data that are sent to your network and then 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 uses a WEP key to

encode or encrypt all network data before it is transmitted. Usually, you can allow the network to assign the WEP key. Alternatively, you can set up your own key, generate a different key, or choose other advanced options. Without the correct key, others will not be able to use 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, follow these steps:

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

is amber, press the wireless button.

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.

If the network is a security-enabled WLAN, you are prompted to enter a network security key, which is a security code. Type the code, and then click OK to complete the connection.

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

NOTE: 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 is

displayed. You can choose to manually search for and connect to a network or to set up a new network connection.

Using a WLAN 19

After the connection is made, place the mouse pointer over the network icon in the notification area, at the far right of the taskbar, to verify the name and status of the connection.

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 the following resources:

Information from your ISP and the manufacturer's instructions included with your wireless router

●

and other WLAN equipment

Information and Web site links provided in Help and Support

●

For a list of public WLANs near you, contact your ISP or search the Web. Web sites 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.

For additional information on connecting your computer to a corporate WLAN, contact your network administrator or IT department.

Roaming to another network

When you move your computer within range of another WLAN, Windows attempts to connect to that network. If the attempt is successful, your computer is automatically connected to the new network. If Windows does not recognize the new network, follow the same procedure you used initially to connect to your WLAN.

20 Chapter 2 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 (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, refer to the Bluetooth software Help.

Bluetooth and Internet Connection Sharing (ICS)

HP does not recommend setting up one computer with Bluetooth as a host and using it as a gateway through which other computers may 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 may not be able to connect to the Internet using the Bluetooth network.

The strength of Bluetooth is in synchronizing information transfers between your 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) 21

Current network security codes are unavailable

If you are prompted for a network key or a name (SSID) when connecting to a WLAN, the network is protected by security. You must have the current codes to make a connection on a secure network. The SSID and network key are alphanumeric codes that you enter into your computer to identify your computer to the network.

For a network connected to your personal wireless router, review the router user guide for

●

instructions on setting up the same codes on both the router and the WLAN device.

For a private network, such as a network in an office or at a public Internet chat room, contact

●

the network administrator to obtain the codes, and then enter the codes when prompted to do so.

Some networks change the SSID or network keys used in their routers or access points on a regular basis to improve security. You must change the corresponding code in your computer accordingly.

Solving travel connection problems

If you experience modem connection problems when using the computer outside of the country in which you purchased it, try the following suggestions:

● Check the telephone line type.

The modem requires an analog, not a digital, telephone line. A line described as a PBX line is usually a digital line. A telephone line described as a data line, fax machine line, modem line, or standard telephone line is usually an analog line.

● Check for pulse or tone dialing.

An analog telephone line supports one of two dialing modes: pulse dialing or tone dialing. These dialing mode options are selected in the Phone and Modem settings. The dialing mode option selected must match the dialing mode supported by the telephone line in your location.

To determine the dialing mode supported by a telephone line, dial a few digits on the telephone, and then listen for clicks (pulses) or tones. Clicks indicate that the telephone line supports pulse dialing. Tones indicate that the telephone line supports tone dialing.

To change the dialing mode in your current modem location setting, follow these steps:

1. Select Start > Devices and Printers.

2. Right-click the device that represents your computer, and click Modem settings.

3. Click the Dialing Rules tab.

4. Select your modem location setting.

5. Click Edit.

6. Click either Tone or Pulse.

7. Click OK twice.

● Check the telephone number you are dialing and the response of the remote modem.

Dial a telephone number, make sure there is a response from the remote modem, and then hang up.

● Set the modem to ignore dial tones.

If the modem receives a dial tone it does not recognize, it does not dial and displays a “No Dial Tone” error message.

To set the modem to ignore all dial tones before dialing, follow these steps:

1. Select Start > Devices and Printers.

2. Right-click the device that represents your computer, and click Modem settings.

3. Click the Modems tab.

4. Click the listing for the modem.
