HP Pavilion Will Not Connect to Wireless

1. Ensure that the wireless network adapter is turned on. Most HP Pavilion notebook computers have a switch that allows you to turn off the wireless adapter. The switch typically is located on the side of the computer or on the front.
2. Ensure that the router and modem are plugged in and functioning. Ensure that the lights are illuminated on each device. Attempt to connect wirelessly using another computer, if possible, to test whether the connection problem is with the router or modem. Unplug the router and modem. Leave the power off for approximately 30 to 60 seconds, then turn them on again.
3. Update the wireless network adapter driver using the computer's 'Device Manager.' To access the Device Manager, right-click on 'Computer' or 'My Computer,' depending on the version of Windows, and click 'Device Manager' from the left-side bar, or from the tab labeled 'Hardware.' Once in the Device Manager, expand the section labeled 'Networking Devices' and right-click on the wireless network adapter. Click 'Update driver software' to begin searching for an update. If an update is found, follow the onscreen instructions to install the update.
4. Reinstall the wireless networking adapter if updating the driver does not remedy the problem. To reinstall the wireless adapter driver, right-click on it from the Device Manager and select 'Uninstall.' Once the device is removed from the computer, restart the computer. Once Windows loads, it will automatically detect and reinstall the driver.
5. Run the Windows 7 Diagnostic Tool (if the computer uses the Windows 7 operating system) to diagnose any networking issues the operating system may be able to correct. To access the Windows 7 Diagnostic Tool, open the 'Start' menu and type 'Network' into the search field. Click 'Network and Sharing Center' and then select 'Diagnose and repair' from the left-side bar. The Windows 7 Diagnostic Tool will automatically run and will attempt to repair and establish the wireless connection.
6. Attempt to manually connect to the wireless network. Open the 'Network and Sharing Center' and click 'Setup a new connection or network.' Enter the network name, security type and network key into the text boxes and click 'Next.' If successful, click 'Use the existing network' and then click 'Connect.' The network name, security type and network key can be obtained from the network administrator or by logging into the router. For help logging into the router, consult the instructions included with the router.
