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. 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. See Windows Help and Support for more information.
