A wireless LAN problem
Problem: You cannot connect to the network using the built-in wireless network card.
Solution:
If your system is installed with Windows 7 operating system, ensure that:
Your wireless LAN driver is the latest version. Check the Web site and conrm that the driver version
supported by the Access Connections program is the latest documented in the readme le.
Your computer is within range of a wireless access point.
The wireless radio is enabled by double-clicking the Access Connections icon on the taskbar.
Check the Network Name (SSID) and your encryption information. Use the Access Connections program
to verify this case-sensitive information.

A wireless WAN problem

Bluetooth problems
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 prole or AV prole.
Solution: Do the following:
1. Exit the program that uses the sound device (for example, Windows Media Player).
2. Go to Control Panel. Click Hardware and Sound Sound Playback.
3. If you are using a Headset prole, select Bluetooth Hands-free Audio and click the Set Default
button. If you are using an AV prole, select Stereo Audio and click the Set Default button.
4. Click OK to close the Sound window.
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 le through
Bluetooth, a PIM item sent from the Windows 7 might be saved as a le with the extension .contact.
