Cannot connect to a preferred 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 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.

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 manufacturer's Web site for the latest software.

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.
