❑ The data transfer distance can be shorter than 33 feet (10 meters) depending on existing obstacles between the two
devices, on radio wave quality, and on the operating system or the software in use. Move your computer and Bluetooth
devices closer to each other.
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 your computer and Bluetooth devices closer to each
other.
❑ 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 may need to move your computer away from obstacles
or closer to the device to which it is connected.
❑ Identify and remove obstacles between your computer and the device to which it is connected.
