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. 86 Chapter 13 Troubleshooting and support

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.
