Fix Bluetooth problems in Windows 10

If you run into problems trying to connect to a Bluetooth device, here are some troubleshooting steps to try.

Before you start

Check these things before you start troubleshooting Bluetooth on your device:

Check your product information

If you’re setting up a new device and Bluetooth is missing, check the product specifications to make sure it has Bluetooth capabilities. Some devices don’t have Bluetooth.

Make sure Bluetooth is turned on

If you're using a laptop with a physical Bluetooth switch on the body, make sure it’s switched on.

In Windows 10, there are two ways to check if Bluetooth is turned on. Here’s how:

Check in the taskbar. Select action center ( or ). If you don’t see Bluetooth, select Expand to reveal Bluetooth, then select Bluetoothto turn it on. You’ll see “Not connected” if your Windows 10 device isn’t paired to any Bluetooth accessories.
Check in Settings. Select Select the Start button, then select Settings > Devices > Bluetooth & other devices . Make sure Bluetooth is turned on.

Notes:

When you turn Bluetooth on in Settings, the following message appears immediately:
"Now discoverable as <computer_name>"

Check your Bluetooth device

Make sure your device is turned on, is charged or has fresh batteries, and is in range of the PC you want to connect to. Then, try the following:

Turn off your Bluetooth device, wait a few seconds, then turn it back on.
Make sure your Bluetooth device is in range. If your Bluetooth device is unresponsive or sluggish, check to make sure it’s not too close to any other USB device that’s plugged into a USB port. Unshielded USB devices can sometimes interfere with Bluetooth connections.

Check your PC

On the PC you want to pair to:

Make sure airplane mode is off: Select Start, then select Settings > Network & Internet > Airplane mode . Make sure Airplane mode is turned off.
Turn Bluetooth on and off: Select Start , then select Settings > Devices > Bluetooth & other devices . Turn off Bluetooth, wait a few seconds, then turn it back on.
Remove the Bluetooth device, then add it again: Select Start , then select Settings > Devices > Bluetooth & other devices .. In Bluetooth, select the device you’re having problems connecting to, and then select Remove device > Yes. To learn more about pairing your Bluetooth device again, see Connect a Bluetooth device.

When Bluetooth doesn't work or the Bluetooth icon is missing

Try these steps if your Bluetooth isn't working. Here are some other common problems:

The Bluetooth icon is missing or Bluetooth can't be turned on or off.
Bluetooth doesn't work after a Windows 10 update is installed.
Bluetooth doesn't work after you upgrade to Windows 10 from Windows or Windows 7.

To get started, select a heading to see more info.

Run the Bluetooth troubleshooter

Select Start , then select Settings > Update & Security > Troubleshoot . In Find and fix other problems, select Bluetooth, and then select Run the troubleshooter and follow the instructions.

Open Troubleshoot settings

Make sure you have the latest drivers

If you recently upgraded to Windows 10 or installed Windows 10 updates, the current driver may have been designed for an earlier version of Windows. To automatically check for driver updates:

In the search box on the taskbar, search for Device Manager, and then select Device Manager from the list of results.
In Device Manager, select Bluetooth, and then select the Bluetooth adapter name, which may include the word “radio.”
Press and hold (or right-click) the Bluetooth adapter, and then select Update driver > Search automatically for updated driver software. Follow the steps, then select Close.
After installing the updated driver, select the Start button, select Power > Restart if you're prompted to restart, and then check whether that fixes the connection issue.

If Windows can’t find a new Bluetooth driver, visit the PC manufacturer’s website and download the latest Bluetooth driver from there.

Important: An outdated or incompatible driver is one of the most common causes of Bluetooth connection problems.

To manually install the Bluetooth driver:

Go to your PC manufacturer's website and download the latest driver. Then do one of the following:

If you downloaded an executable (.exe) file, just double-click the file to run it and install the drivers. That should be all you need to do.
If you downloaded individual files, and at least one file has an .inf file name extension and another has a .sys extension, do the following:
1. In the search box on the taskbar, type Device Manager, and then select Device Manager from the list of results.
2. In Device Manager, select Bluetooth > the Bluetooth adapter name. (If it’s not listed there, check in Other devices.)
3. Press and hold (or right-click) the network adapter, and then select Update driver > Browse my computer for driver software.
4. Select Browse, select the location where the driver files are stored, and then select OK.
5. Select Next, and follow the steps to install the driver. When the installation is finished, select Close.
6. After you've updated the driver, select the Start button, select Power > Restart if you're prompted to restart, and check whether that fixes the connection issue.

Uninstall the Bluetooth adapter in Device Manager

If you don't see the Bluetooth icon, but Bluetooth does appear in Device Manager, try to uninstall the Bluetooth adapter and trigger an automatic reinstall. Here's how:

In the search box on the taskbar, enter device manager, then select Device Manager from the results.
In Device Manager, select Bluetooth. Press and hold (or right-click) the Bluetooth adapter name (which may include the word “radio”), and select Uninstall device.
Select Start , then select Power > Shut down .
After your device shuts down, wait a few seconds, and then turn it back on. Windows will try to reinstall the driver.
If Windows doesn't reinstall the driver automatically, open Device Manager and select Action > Scan for hardware changes.

Note: You may need to contact your PC or other hardware manufacturer to obtain the latest drivers for your Bluetooth adapter.

If these methods don't fix your Bluetooth problem, use Windows Feedback Hub to file a bug. This helps Microsoft determine the root cause of this issue.
