1 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:
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.
HP Broadband Wireless Module (WWAN device)—Provides access to information wherever
●
mobile network operator service is available. In a WWAN, each mobile device communicates to a
mobile network operator’s base station. Mobile network operators install networks of base stations
(similar to cell phone towers) throughout large geographic areas, effectively providing coverage
across entire states, regions, or even countries.
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 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 270 Mbps and may operate at 2.4 GHz or 5 GHz, making it
●
backward compatible with 802.11a, b, and g.

8 Chapter 2 Setting up a WLAN (select models only)
Preparing the router and the computer
Since the HP Network Assistant is a Web-based application, you must use an Ethernet cable to establish
a good Internet connection from your computer through a router and a modem to your ISP.
NOTE: If you do not have an Internet connection, you must contact an ISP and set up your service
before you can connect to the Internet.
Use the following steps to establish the wired connection:
1. If you have not already done so, connect the modem (1) (either DSL or cable modem) to the phone
or cable TV jack on the wall.
2. Connect the wireless router (purchased separately) (2) to the cable or DSL modem using an
Ethernet cable.
3. Connect the router to the computer (3) using an Ethernet cable.
4. Verify that your computer can access the Internet by opening Internet Explorer and connecting to
any Web site, such as

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.
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)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. However, you can take precautions to protect
your 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 for data that are sent to your 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. 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.
Close your network
●
If possible, prevent your network name (SSID) from being broadcast by the wireless transmitter.
Most networks initially broadcast the name, telling any computer nearby that your network is
available. By closing the network, other computers are less likely to know that your network exists.
NOTE: If your network is closed and the SSID is not broadcast, you will need to know or remember
the SSID to connect new devices to the network. Write down the SSID and store it in a secure
place before closing the network.
14 Chapter 2 Setting up a WLAN (select models only)
3 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: 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.
NOTE: 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).
15
Connecting to a WLAN
To connect to the WLAN, follow these steps:
1. Be sure that the WLAN device is turned on. If it is on, the wireless light is on. If the wireless light
is off, press the wireless button.
NOTE: On some models, the wireless light is amber when all wireless devices are turned off.
2. Select Start > Connect to.
3. Select your WLAN from the list, and then type the network security key, if required.
If the network is unsecured, meaning that anyone can access the network, a warning is
●
displayed. Click Connect Anyway to accept the warning and complete the connection.
If the network is a security-enabled WLAN, you will be prompted to enter a network security
●
key, which is a security code. Click Connect 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 Set up a connection or
network. A list of options will be displayed. You can choose to manually search for and connect
to a network or to create a new network connection.
4. After the connection is made, place the cursor over the network status icon in the notification area,
at the far right of the taskbar, to verify the name, speed, strength, 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 user guides 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.
16 Chapter 3 Using a WLAN
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 will be 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.
Roaming to another network 17
4 Using HP Broadband Wireless (select
models only)
HP Broadband Wireless enables your computer to access the Internet from more places and over larger
areas than WLANs. Using HP Broadband Wireless requires a network service provider (called a mobile
network operator), which in most cases will be a mobile phone network operator. Coverage for HP
Broadband Wireless is similar to mobile phone voice coverage.
When used with mobile network operator service, HP Broadband Wireless gives you the freedom to
stay connected to the Internet, send e-mail, or connect to your corporate network whether you are on
the road or outside the range of Wi-Fi hotspots.
HP offers two types of broadband wireless modules:
The HSDPA (High Speed Downlink Packet Access) module provides access to networks based
●
on the Global System for Mobile Communications (GSM) telecommunications standard.
The EV-DO (Evolution Data Optimized) module provides access to networks based on the code
●
division multiple access (CDMA) telecommunications standard.
For information on HP Broadband Wireless, see the HP Web site at
broadbandwireless.

5 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.
19
Bluetooth and Internet Connection Sharing (ICS)
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.
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. 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.
20 Chapter 5 Using Bluetooth wireless devices (select models only)
6 Troubleshooting wireless connection
problems
Some possible causes for wireless connection problems include the following:
Wireless device is not installed correctly or has been disabled.
●
Wireless device or router hardware has failed.
●
Network configuration (SSID or security) has been changed.
●
Wireless device encountered interference from other devices.
●
NOTE: Wireless networking devices are included with select computer models only. If wireless
networking is not listed in the feature list on the side of the original computer package, you may add
wireless networking capability to the computer by purchasing a wireless networking device.
Before working your way through the sequence of possible solutions to your network connection
problem, be sure that device drivers are installed for all wireless devices.
Use the procedures in this chapter to diagnose and repair a computer that does not connect to the WLAN
you want to use.
21
Cannot connect to a WLAN
If you have a problem connecting to a WLAN, confirm that the integrated WLAN device is properly
installed on your computer:
NOTE: Windows includes the User Account Control feature to improve the security of your computer.
You may be prompted for your permission or password for tasks such as installing software, running
utilities, or changing Windows settings. Refer to Windows Help for more information.
1. Select Start > Computer > System properties.
2. In the left pane, click Device Manager.
3. Identify the WLAN device from the Network adapters list. The listing for a WLAN device may include
the term wireless, wireless LAN, WLAN, or 802.11.
If no WLAN device is listed, either your computer does not have an integrated WLAN device, or
the driver for the WLAN device is not properly installed.
For more information on troubleshooting WLANs, refer to the Web site links provided in Help and
Support.
22 Chapter 6 Troubleshooting wireless connection problems
Cannot launch WLAN
Windows can automatically repair a corrupted WLAN connection:
If there is a network status icon in the notification area, at the far right of the taskbar, right-click the
●
icon, and then click Diagnose and repair from the menu.
Windows will reset your network device and attempt to reconnect to one of the preferred networks.
If an “x” is superimposed over the network status icon, one or more of your WLAN or LAN drivers
●
are installed but the computer is not connected.
If there is no network status icon in the notification area, follow these steps:
●
1. Click Start and type network and sharing in the Start Search box.
2. From the list of search results, click Network and Sharing Center.
3. In the left pane, click Diagnose and repair.
When the Network connections window is displayed, Windows will reset your network device and

software driver is either missing or corrupted. A Windows “Device not Found” error message may also
be displayed. The driver must be reinstalled.
Get the latest version of the WLAN device software for your computer at the HP Drivers and Downloads
Web site. If the WLAN device you are using was purchased separately, consult the manufacturer's Web
site for the latest software.
24 Chapter 6 Troubleshooting wireless connection problems
Current network security codes are unavailable
If you are prompted for a network key or an SSID when connecting to a WLAN, the network is protected
by security. You will need to have the current codes to make a connection on a secure network. The
SSID and WEP 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 SSID 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 Service Site Identifier (SSID) codes, and then enter the codes
when prompted to do so.
Some networks change the SSIDs used in their routers or access points on a regular basis to
improve security. You must change the corresponding SSID code in your computer accordingly.
If you are provided with new wireless network keys and SSIDs for a network, and if you have previously
connected to that network, follow the steps below to connect to the network:
1. Click Start > Network > Network and Sharing Center > Manage wireless networks.
A list showing the available WLANs is displayed. If you are in a hotspot where several WLANs are
active, several will be displayed.
2. Right-click the network, and then click Properties.
NOTE: If the network you want is not listed, check with the network administrator to be sure that
the router or access point is operating.
3. Click the Security tab and enter the correct wireless encryption data into the Network security
key field.
4. Click OK to save these settings.
Current network security codes are unavailable 25
WLAN connection is very weak
If the connection is very weak, or if your computer cannot make a connection to a WLAN, minimize
interference from other devices, as follows:
Move your computer closer to the wireless router or access point.
●
Be sure that other wireless devices are not interfering by temporarily disconnecting devices such
●
as a microwave, cordless phone, or cellular phone.
If the connection does not improve, try forcing the device to reestablish all connection values:
1. Click Start > Network > Network and Sharing Center > Manage wireless networks.
A list showing the available WLANs is displayed. If you are in a “hotspot” where several WLANs
are active, several will be displayed.
2. Right-click a network, and then click Remove.
26 Chapter 6 Troubleshooting wireless connection problems
Cannot connect to the wireless router
If you are trying to connect to the wireless router and are unsuccessful, reset the wireless router by
removing power from the router for 10 to 15 seconds.
If the computer still cannot make a connection to a WLAN, restart the wireless router. For details, refer
to the router user guide.
Cannot connect to the wireless router 27
Cannot connect to a wireless network used previously
If you are unable to resolve the issue of a wireless connection that worked previously but does not work
now, performing a system restore may be the final option. Microsoft® System Restore, if set up to do
so, will create restore points automatically and periodically. Use an existing restore point to return your
system to the condition it was in when the wireless connection worked.
