Bluetooth is a powerful wireless technology that allows users to connect devices such as keyboards, mice, printers and other peripherals to the computer without the hassle of wires. Although Bluetooth technology is quite eloquent in its simplicity, enabling the functionality and connecting a device for the first time can be difficult because the initial settings are a bit buried in the computer's system preferences.
Turn off any Bluetooth devices. If your computer detects the device before the functionality has been completely configured, it can cause problems with future connectivity with the device.
