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 Internet 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.
