Why isn't my wireless device working properly after I paired it with my computer?

There are many reasons why a wireless device might stop working properly after you've added it to your computer. Here are some tips to help you get the device working again:

• Make sure the device is within wireless range of your computer, typically within 6-9 feet for most Bluetooth enabled devices, or within 100 feet for a Wi‑Fi device. If you aren't sure if the device is in range, try moving it closer to your computer. If there is a wall between the device and the computer, try putting the device and computer in the same room.
• Make sure the device isn't too busy and doesn't have too many connections (for example, other devices might be connected to a Bluetooth printer). If the device is busy, wait a little while and then try again. If the device seems to have too many connections, set the other devices so that they aren't discoverable. If you're not sure how to turn off discoverability, check the information that came with the devices or go to the manufacturers' websites.
• Try removing and reinstalling the device:
  1. Click to open Devices and Printers.
  2. Right click the device that's not working, and then click Remove device. If you don't see the device listed, continue to the next step.
  3. Click Add a device.
  4. Select your device, click Next, and then follow the instructions. If the device isn't listed, you might have to make the device discoverable by pressing a small button labeled "Connect," "Pair," or something similar. Some devices, such as mobile phones, might have a menu option that you need to select to make them discoverable. Check the instructions that came with the device or go to the manufacturer's website.
• Make sure that your computer is trying to connect to the correct device. There might be more than one device like the one you are trying to add, especially if you are in a large office or public place.
• Make sure that you typed the correct pairing code (sometimes called a PIN or passcode) for the device. For more information, see the section in this topic: "How do I find or enter a pairing code for my wireless device?"
• Try moving the device away from other devices that use radio frequencies, such as microwave ovens, cordless phones, or wireless networks, to make sure those devices aren't interfering with the wireless signal.
• After you turn on a wireless device, or move it within range of your computer, wait several seconds for Windows to discover it.
• Make sure your network firewall isn't blocking the device from appearing in the list of devices you can add. You might need to turn on network discovery. For information, see Enable or disable network discovery.
• Make sure software drivers for the device have been properly installed. If there's a problem with this, Windows should display a yellow warning icon for the device in the Devices and Printers folder.
