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: ● 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 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: 1. Select Start > My Computer. 2.

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:

●

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.

●

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.
