Troubleshooting

Why is my Bluetooth connection slow?

❑The data transfer speed depends on the obstructions and/or the distance between the two devices, on the radio wave quality, and on the operating system or the software in use. Move Bluetooth devices closer to your computer.

❑The 2.4 GHz radio frequency used by Bluetooth and wireless LAN devices is also used by other devices. Bluetooth devices incorporate technology that minimizes interference from other devices using the same wavelength, however, communication speed and connection range may be reduced. Interference from other devices may also stop communications altogether.

❑Connection capability is affected by distance and obstructions. You need to place your computer away from obstacles or move the device to which it is connected closer to the computer.

❑Identify and remove obstacles between your computer and the device to which it is connected.

❑Note that large files may occasionally be corrupted during continuous transfer due to limitations of the Bluetooth standard and electromagnetic interference in the environment.

Why can't I use the services supported by the connected Bluetooth device?

Connection is only possible for services also supported by the computer with the Bluetooth function. For more details, search for Bluetooth information using Windows Help and Support. To open Windows Help and Support, click Start and Help and Support.

Why can't I use the Bluetooth function when I log onto my computer as a user with a standard user account?

The Bluetooth function may not be available to a user with a standard user account on your computer. Log onto the computer as a user with administrative rights.
