    							Cannot connect to a WLAN
    If you have a problem connecting to a WLAN, confirm that the integrated WLAN device is turned on
    and properly installed on your computer.
    1.If the wireless light is off or amber, press the wireless button, wireless switch, or wireless key to
    turn the wireless device on.
    2.Then try connecting to the WLAN again.
    If you are still unable to connect, follow the steps below.
    1.Select Start > Control Panel > System and Security.
    2.In the System area, click Device Manager.
    3.Click the arrow next to Network adapters to expand the list and show all adapters.
    4.Identify the WLAN device from the Network adapters list. The listing for a WLAN device may
    include the term wireless, wireless LAN, WLAN, or 802.11.
    If no WLAN device is listed, either your computer does not have an integrated WLAN device, or
    the driver for the WLAN device is not properly installed.
    For more information about troubleshooting WLANs, see the website links provided in Help and
    Support.
    Cannot connect to a preferred network
    You may not be able to connect to a preferred network because it is a security-enabled WLAN. You
    must have the security code to connect to this type of WLAN. See the next section for additional
    information.
    If entering a security code is not the problem, you may have a corrupted WLAN connection. Many
    times, Windows can automatically repair a corrupted WLAN connection.
    ●If there is a network status 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 status icon in the notification area, follow these steps:
    1. Start > Control Panel > Network and Internet > Network and Sharing Center.
    2.Click Troubleshoot problems and select the network you wish to repair.
    Troubleshooting 85 
    						
    							Current network security codes are unavailable
    If you are prompted for a security code (or 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 security code 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.
    If you are provided with new wireless network keys and SSID for a network, and if you have
    previously connected to that network, follow the steps below to connect to the network:
    1.Select Start > Control Panel > Network and Internet > Network and Sharing Center.
    2.In the left panel, click Manage wireless networks.
    A list showing the available WLANs is displayed. If you are in a hotspot where several WLANs
    are active, several will be displayed.
    3.Select the network in the list, right-click the network, and then click Properties.
    NOTE:If the network you want is not listed, check with the network administrator to be sure
    that the router or access point is operating.
    4.Click the Security tab and enter the correct wireless encryption data into the Network security
    key box.
    5.Click OK to save these settings.
    WLAN connection is very weak
    If the connection is very weak, or if your computer cannot make a connection to a WLAN, minimize
    interference from other devices, as follows:
    ●Move your computer closer to the wireless router or access point.
    ●Temporarily disconnect wireless devices such as a microwave, cordless phone, or cellular
    phone to be sure that other wireless devices are not interfering.
    If the connection does not improve, try forcing the device to reestablish all connection values:
    1.Select Start > Control Panel > Network and Internet > Network and Sharing Center.
    2.In the left panel, click Manage wireless networks.
    A list showing the available WLANs is displayed. If you are in a hotspot where several WLANs
    are active, several will be displayed.
    3.Click a network, and then click Remove.

    							Cannot connect to the wireless router
    If you are trying to connect to the wireless router and are unsuccessful, reset the wireless router by
    removing power from the router for 10 to 15 seconds.
    If the computer still cannot make a connection to a WLAN, restart the wireless router. For details, see
    the router manufacturers instructions.
    Network status icon is not displayed
    If the network status 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.
    Get the latest version of the WLAN device software and drivers for your computer from the HP
    website at 
    http://www.hp.com. If the WLAN device you are using was purchased separately, consult
    the manufacturers website for the latest software.
    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 manufacturers
    website for the latest software.
