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 band, with which BLUETOOTH devices or wireless LAN devices work, is used by various devices. Although BLUETOOTH devices use the technology to minimize radio interference from other devices that use the same band, such radio interference may cause slower communication speeds and shorter distances or communication failures. If a version of a BLUETOOTH standard employed on the BLUETOOTH device with which you want to communicate is not the same version as the one employed on your computer, the communication speed becomes slower. High-speed communications between your computer and BLUETOOTH devices are available when they are compliant with BLUETOOTH high speed technology. For the high-speed communications, enable both the wireless LAN and BLUETOOTH functions on the computer. ! Some BLUETOOTH profiles do not support high-speed communications.
