HP Pavilion Dv3 4300 Entertainment Notebook Pc Series Manual

							Using Bluetooth wireless devices
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 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 Help and Support for more
information.
1.Select Start > Control Panel > System and Security.
2.In the System area, click Device Manager.
3.Click the arrow next to Network adapters to expand the list and show all adapters.
4.Identify the WLAN device from the Network adapters list. The listing for a WLAN device may
include the terms wireless, wireless LAN, WLAN, Wi-Fi, or 802.11.
If no WLAN device is listed, either your computer does not have an integrated WLAN device, or
the driver of the WLAN device is not properly installed.
For more information on troubleshooting WLANs, refer to the Web site links provided in Help and
Support.

							Cannot connect to a preferred WLAN network
Windows can automatically repair a corrupted WLAN connection:
●If there is a network icon in the notification area, at the far right of the taskbar, right-click the
icon, and then click Troubleshoot problems.
Windows resets your network device and attempts to reconnect to one of the preferred
networks.
●If there is no network icon in the notification area, follow these steps:
1.Select Start > Control Panel > Network and Internet > Network and Sharing Center.
2.Click Troubleshoot problems and select the network you wish to repair.
Network icon is not displayed
If the network status icon is not displayed in the notification area after you configure the WLAN, the
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 and drivers for your computer from the HP Web
site at 
http://www.hp.com. If the WLAN device you are using was purchased separately, consult the
manufacturers Web site for the latest software.
To get the latest version of the WLAN device software for your computer, follow these steps:
1.Open your Web browser and go to 
http://www.hp.com/support.
2.Select your country or region.
3.Click the option for software and driver downloads, and then type your computer model number
in the Search box.
4.Press enter, and then follow the on-screen instructions.
NOTE:If the WLAN device you are using was purchased separately, consult the manufacturers
Web site for the latest software.
Current WLAN 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 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.
Troubleshooting wireless connection problems 23 
						

							If you are provided with new wireless network keys and SSID for a network, and if you have
previously connected to that network, these steps to connect to the network:
1.Select Start > Control Panel > Network and Internet > Network and Sharing Center.
2.Click Manage wireless networks in the left panel.
A list showing the available WLANs is displayed. If you are in a hotspot where several WLANs
are active, several are displayed.
3.Select the network in the list, 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.
4.Click the Security tab and enter the correct wireless encryption data into the Network security
key box.
5.Click OK to save these settings.
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.
●Temporarily disconnect devices such as a microwave, cordless phone, or cellular phone to be
sure that other wireless devices are not interfering.
If the connection does not improve, try forcing the device to reestablish all connection values:
1.Select Start > Control Panel > Network and Internet > Network and Sharing Center.
2.Click Manage wireless networks in the left panel.
A list showing the available WLANs is displayed. If you are in a hotspot where several WLANs
are active, several are displayed.
3.Click a network, and then click Remove.
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 manufacturers instructions.
24 Chapter 2   Wireless and local area network 
						

							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 device.
To connect the network cable:
WARNING!To reduce the risk of electric shock, fire, or damage to the equipment, do not plug a
modem cable or telephone cable into an RJ-45 (network) jack.
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).
