A wireless LAN problem
Problem: I cannot connect to the network using the built-in wireless network card.
Solution: Make sure that:
• The airplane mode is off.
• 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 Windows
notification area. 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.
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. Go to 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.
4. Click OK to close the Sound window.
