A wireless WAN problem

Note: Depending on your computer, 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 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. Open Control Panel and 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 system 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.
