A wireless LAN problem

Problem: I cannot connect to the network using the built-in wireless network card.

Solution: Make sure that:

•Your wireless LAN driver is the latest version.

•Your computer is within range of a wireless access point.

•The wireless radio is enabled.

Note: If you are using the Windows 7 operating system, click Show hidden icons on the taskbar. The Access Connections icon is displayed. For more information about the icon, refer to the Access Connections help information system.

For the Windows 7 operating system, check the Network Name (SSID) and your encryption information. Use the Access Connections program to verify this case-sensitive information.

A wireless WAN problem

Problem: A message is displayed indicating that an unauthorized WAN card is installed.

Solution: The WAN card is not supported on this computer. Remove the WAN card.

Note: Some models do not have a wireless WAN card.

Bluetooth problems

Note: Check your connection anytime and make sure that no other Bluetooth-enabled device is searching for the device to which you want to connect. Simultaneous searching is not allowed in the Bluetooth connection.

•Problem: Sound does not come from the Bluetooth headset/headphone but comes from the local speaker even though the Bluetooth headset/headphone is connected using a Headset profile or AV profile.

Solution: Do the following:

1.Exit the application that uses the sound device (for example, Windows Media Player).

2.Open Control Panel and click Hardware and Sound ➙ Sound ➙ Playback.

3.If you are using a Headset profile, select Bluetooth Hands-free Audio and click the Set Default button. If you are using an AV profile, select Stereo Audio and click the Set Default button.

•Problem: PIM items sent from the Windows 7 operating systems cannot be received correctly into the address book of any other Bluetooth-enabled device.

Solution: The Windows 7 operating system sends PIM items in XML format, but most Bluetooth-enabled devices handle PIM items in vCard format. If another Bluetooth-enabled device can receive a file through Bluetooth, a PIM item sent from the Windows 7 might be saved as a file with the extension .contact.
