							Using a Bluetooth wireless device
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.

							Troubleshooting wireless connection problems
Some possible causes for wireless connection problems include the following:
●Network configuration (SSID or security) has been changed.
●Wireless device is not installed correctly or has been disabled.
●Wireless device or router hardware has failed.
●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
network you want to use.
Cannot create a WLAN connection
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 Help and Support for more information.

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.
If you are provided with new wireless network keys and SSID for a network, and if you have previously
connected to that network, follow these steps to connect to the network:
1.Select Start > Control Panel > Network and Internet  > Network and Sharing Center.

							Using the modem (select models only)
The modem must be connected to an analog telephone line using a 6-pin, RJ-11 modem cable
(purchased separately). In some countries or regions, a country- or region-specific modem cable adapter
(purchased separately) is also required. Jacks for digital PBX systems may resemble analog telephone
jacks, but they are not compatible with the modem.
WARNING!Connecting the internal analog modem to a digital line can permanently damage the
modem. Immediately disconnect the modem cable if you accidentally connect it to a digital line.
If the modem cable contains noise suppression circuitry (1), which prevents interference from TV and
radio reception, orient the circuitry end (2) of the cable toward the computer.
Connecting a modem cable
WARNING!To reduce the risk of electric shock, fire, or damage to the equipment, do not plug a modem
cable (purchased separately) or telephone cable into the RJ-45 (network) jack.
To connect a modem cable:

in which you purchased the computer. As you travel to different countries or regions, set the internal
modem to a location setting that meets the operating standards of the country or region in which you
are using the modem.
As you add new location settings, they are saved by the computer so that you can switch among settings
at any time. You can add multiple location settings for any country or region.
CAUTION:To prevent losing your home country or region settings, do not delete your current modem
country or region settings. To enable modem use in other countries or regions while preserving your
home country or region configuration, add a new configuration for each location in which you will use
the modem.
CAUTION:To prevent configuring the modem in a way that violates the telecommunications
regulations and laws of the country or region you are visiting, select the country or region in which the
computer is located. The modem may not function properly if the correct country or region selection is
not made.
To add a location setting for the modem, follow these steps:
1.Select Start > Devices and Printers.
2.Right-click the device that represents your computer, and click Modem settings.

							Solving travel connection problems
If you experience modem connection problems when using the computer outside of the country or region
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 2 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.
5.Click Properties.
6.Click Modem.

							7.Clear the check box for Wait for dial tone before dialing.
8.Click OK twice.
Connecting to a local area network (LAN)
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).
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.
