Bluetooth device connections are slow or stop working

If your Bluetooth devices are slow or stop working, check the following:

• Are the devices the correct distance apart? The devices could be at the edge of their range or too close to each other. Move the devices closer together. If that does not work, move the devices farther apart. Also, read the documentation for the device to determine the correct the transmission range.
• Is one of the devices too busy? For example, other programs might be connecting to the printer, preventing this connection. To reduce the number of connections, set your other devices so that they are not discoverable.
• Are other devices interfering? The Bluetooth radio frequency is 2.4 gigahertz (GHz). Other devices might be in the same frequency range as your Bluetooth devices. These can include:
  • Cordless telephones that use the 2.4 GHz range
  • Microwave ovens
  • X10 devices, such as those that control automatic lighting and universal remote controls
  • Wireless networks using the 802.11 standard (also called Wi-Fi networks)

    If you think this is the problem, try moving your Bluetooth device farther from the source of interference.

  If your Bluetooth keyboard or mouse does not work, try the following:

  1. Connect a wired keyboard or mouse to your computer.
  2. Open Bluetooth Devices in Control Panel.
  3. Click the Bluetooth device that is not responding, and then click Remove.
  4. Click Add, select the My device is set up and ready to be found check box, and then click Next. If the device is not found, click Search Again.
  5. When the device is found, select it, and then click Next.
  6. If the device is a keyboard, exchange passkeys with the keyboard.
  7. If the device is a mouse, click Don't use a passkey.
  8. Follow the rest of the instructions in the wizard.

Security might have been reset on either device. This is especially common with keyboards and mice. Other devices can have similar problems and might need to be reinstalled.
