Troubleshooting

Why is my Bluetooth connection slow?

❑

The data transfer speed depends on the obstacles and/or the distance between the two devices, but also on the radio

wave quality, on the operating system or the software used. Try to move the computer or try to place the two devices

closer.

❑

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

communication altogether.

❑

Connection availability is affected by distance and obstructions. You may need to move the computer away from

obstructions or closer to the device to which it is connected.

❑

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

❑

Note that due to limitations of the Bluetooth standard, large files may occasionally be corrupted during continuous transfer

due to electromagnetic interference from the environment.

What should I do if the message requesting authentication appears?

The target Bluetooth enabled device is requesting connection authentication. Mutual authentication is required to enable

Bluetooth communications with this device.

Why can't I connect to service supported by the target Bluetooth device?

Connection is only possible for services also supported by the computer with the Bluetooth functionality. For more details,

see the help file on the Bluetooth utility software.
