Troubleshooting and Maintenance

Troubleshooting Your Computer

If you cannot connect to a particular computer on the network

∙Make sure the computer is properly connected to the network.

∙Make sure your TCP/IP setup is correct for your network: in Control Panel, open Network Connections.

If you can connect, but the network is slow

∙Check whether you might be in an area served by more than one wireless LAN. If so, the LANs could be interfering with each other.

∙Move closer to the access point (for an infrastructure connection) or other wireless computer (for an AdHoc connection). You could be too far away for high-speed communication.

If your computer cannot detect any Bluetooth devices

∙Make sure the wireless indicator light is on.

∙Make sure Bluetooth communication is turned on. Click Start, All Programs, Hewlett- Packard, Notebook, HP Wireless Configuration, then click the Bluetooth button if it’s not turned on. If no Bluetooth button is shown, your computer does not support Bluetooth communication.

∙Make sure the Bluetooth devices are turned on. Some Bluetooth phones must be set for detection and may be detectable by other devices for only a short time.

If your computer cannot detect a certain Bluetooth device

∙Make sure the Bluetooth device is turned on. Some Bluetooth phones must be set for detection and may be detectable by other devices for only a short time.

∙Refresh the list of Bluetooth devices. Double-click the Bluetooth icon in the taskbar, then click Bluetooth, Search For Devices in the menu bar.
