							If no WLAN device is listed, either your computer does not have an integrated WLAN device, or
the driver of the WLAN device is not properly installed.
For more information on troubleshooting WLANs, refer to the Web site links provided in Help and
Support.
Cannot connect to a preferred WLAN 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 a network to repair.
Network icon for WLAN 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 Web
site at 
http://www.hp.com. If the WLAN device you are using was purchased separately, consult the
manufacturers Web site for the latest software.
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 manufacturers
Web site for the latest software.
Current WLAN 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.
Troubleshooting wireless connection problems 21 
						

							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 are displayed.
3.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, follow the
steps below to minimize interference from other devices:
●Move your computer closer to the wireless router or access point.
●Temporarily disconnect devices such as a microwave, cordless phone, or cellular phone to be
sure that other wireless devices are not interfering.
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,
refer to the router manufacturers instructions.
Connecting to a local area network (LAN)
Connecting to a local area network (LAN) requires an 8-pin, RJ-45 network cable (purchased
separately). If the network cable contains noise suppression circuitry (1), which prevents interference
from TV and radio reception, orient the circuitry end of the cable (2) toward the device.
To connect the network cable:

Cleaning the TouchPad and keyboard
Dirt and grease on the TouchPad can cause the pointer to jump around on the screen. To avoid this,
clean the TouchPad with a damp cloth, and wash your hands frequently when using the computer.
WARNING!To reduce the risk of electric shock or damage to internal components, do not use a
vacuum cleaner attachment to clean the keyboard. A vacuum cleaner can deposit household debris
on the keyboard surface.
Clean the keyboard regularly to prevent keys from sticking and to remove dust, lint, and particles that
can become trapped beneath the keys. A can of compressed air with a straw extension can be used
to blow air around and under the keys to loosen and remove debris.
