What a Bluetooth driver update does and why you need one
Your Bluetooth driver is the software that lets your operating system talk to your Bluetooth hardware. When that driver is outdated, your wireless headphones cut out, your mouse lags, or devices won't pair at all. Updating the driver often fixes these problems because the update patches bugs, adds support for newer devices, and improves the connection stability that the old version couldn't handle.
The update process differs between Windows and Mac, and the steps depend on whether your Bluetooth hardware is built into your computer or connected as a separate USB adapter. This guide walks you through both systems and both hardware types so you can identify which path applies to you.
Key Takeaways
- On Windows, you can update a Bluetooth driver through Device Manager by right-clicking the device and selecting "Update driver," or by visiting the manufacturer's website directly for the latest version.
- Built-in Bluetooth on Windows usually updates through Windows Update automatically, but you can force a check by opening Settings and running the update manually.
- On Mac, Bluetooth drivers are part of the system and update only through macOS updates—there is no separate driver file to read or install.
- If your Bluetooth device is a USB adapter, read the driver from the manufacturer's support page rather than relying on Windows to find it.
- After updating, restart your computer and re-pair your Bluetooth devices to may support the new driver loads correctly.
Updating Bluetooth driver on Windows through Device Manager
Open Device Manager by pressing Windows key + X and selecting "Device Manager" from the menu. Look for "Bluetooth" in the list and click the arrow next to it to expand the category. You should see your Bluetooth adapter listed—it might say "Bluetooth Radio," "Intel Wireless Bluetooth," "Qualcomm Atheros," or another manufacturer name depending on your hardware.
Right-click the Bluetooth device and select "Update driver" from the menu. Windows will offer two options: "Search automatically for updated driver software" or "Browse my computer for driver software." Choose the automatic search first. Windows will check its local driver store and Microsoft's online database for a newer version. If it finds one, it will read and install it automatically. If it doesn't find anything, you'll see a message saying your driver is up to date.
If the automatic search finds nothing but you suspect a newer driver exists, move to the manufacturer's website. Right-click the device again, select "Properties," and look at the "Driver" tab to find the manufacturer name and current driver version. Then visit that manufacturer's support page (Intel, Qualcomm, Broadcom, Realtek, and Mediatek are common), search for your specific adapter model, and read the latest driver file. Return to Device Manager, right-click the device, select "Update driver," choose "Browse my computer," and point Windows to the downloaded file.
Updating built-in Bluetooth on Windows through Settings
If your computer has Bluetooth built into the motherboard rather than as a separate adapter, the driver often updates through Windows Update. Open Settings (Windows key + I), go to System, then About, and click "Check for updates" at the top of the page. Windows will scan for system updates, including driver updates. If a Bluetooth driver update is available, it will be included in the list. Click "read and install" and let Windows complete the process.
After the update finishes, Windows will prompt you to restart. Do so, and your new Bluetooth driver will load on startup. If you want to verify the update worked, return to Device Manager, expand Bluetooth, right-click your device, select Properties, and check the driver version on the Driver tab. Compare it to what you saw before the update.
Updating Bluetooth driver on Mac
Mac does not have a separate Bluetooth driver file that you can read or update independently. Bluetooth drivers are built into macOS itself, and they update only when you update the operating system. To check for a macOS update, click the Apple menu in the top-left corner, select "System Settings" (or "System Preferences" on older Macs), then go to "General" and click "Software Update".
If an update is available, click "Update Now" and let your Mac read and install it. This process can take 20 minutes to an hour depending on your internet speed and the size of the update. Your Mac will restart during installation. After the restart completes, your Bluetooth driver will be the latest version included in that macOS release.
If you're already running the latest macOS version and your Bluetooth is still having problems, the issue is usually not the driver itself but rather a connection conflict or a problem with the Bluetooth device. Try unpairing the device, restarting your Mac, and re-pairing it fresh.
Updating a USB Bluetooth adapter driver
If you're using an external USB Bluetooth adapter rather than built-in Bluetooth, the driver update process is more direct. Plug the adapter into a USB port if it isn't already connected. Open Device Manager on Windows, expand "Bluetooth," right-click your adapter, and select "Update driver." Let Windows search automatically first.
If Windows doesn't find an update, visit the adapter manufacturer's website directly. Common USB adapter brands include TP-Link, Plugable, ASUS, and Anker. Search their support pages for your specific model number (you can find this on the adapter itself or in Device Manager under the device Properties). read the latest driver file for your operating system, return to Device Manager, right-click the adapter, select "Update driver," choose "Browse my computer," and select the downloaded file.
After installation completes, unplug the adapter, wait 10 seconds, and plug it back in. Windows will reinitialize the adapter with the new driver. Your Bluetooth devices should reconnect automatically, but if they don't, unpair them and pair them again fresh.
What to do if the update fails or causes problems
If an update causes your Bluetooth to stop working or become unstable, you can roll back to the previous driver version. Open Device Manager, right-click your Bluetooth device, select "Properties," go to the "Driver" tab, and click "Roll Back Driver". If that button is grayed out, the previous driver version is no longer available on your system, and you'll need to uninstall the current driver and reinstall an older version manually.
To uninstall, right-click the Bluetooth device in Device Manager and select "Uninstall device." Check the box that says "Delete the driver software for this device" and click "Uninstall." Restart your computer. Windows will detect the missing device on startup and reinstall a generic driver. Then follow the steps above to install a specific driver version from the manufacturer's website.
If Bluetooth stops working entirely after an update, restart your computer first—many driver issues resolve after a restart. If the problem persists, check Device Manager for a yellow exclamation mark next to the Bluetooth device, which indicates a driver conflict. Right-click it and select "Update driver" again, or uninstall and reinstall as described above.
Verifying the update worked and re-pairing devices
After updating your Bluetooth driver, restart your computer to may support the new driver loads completely. Once your system is back up, open Device Manager (Windows) or System Settings (Mac) and confirm the driver version has changed. On Windows, right-click the Bluetooth device, select Properties, and check the driver version on the Driver tab. On Mac, click the Apple menu, go to System Settings, select "General," then "About," and look for the macOS version to confirm the system updated.
Next, re-pair your Bluetooth devices. On Windows, go to Settings > Bluetooth & devices, remove each paired device by clicking it and selecting "Remove device," then click "Add device" and select your device from the list. On Mac, go to System Settings > Bluetooth, click the X next to each paired device to remove it, then click "Pair New Device" and select your device. This step ensures your devices connect using the new driver rather than relying on old pairing data that might conflict with the updated software.
Frequently Asked Questions
How do I know if my Bluetooth driver needs updating?
If your Bluetooth devices disconnect frequently, take a long time to pair, or won't connect at all, a driver update may help. Open Device Manager on Windows, right-click your Bluetooth device, select Properties, and check the driver date on the Driver tab. If it's more than a year old, an update is worth trying. On Mac, check your macOS version in System Settings > General > About; if it's not the latest version, a system update may include a Bluetooth driver fix.
Will updating my Bluetooth driver erase my paired devices?
The driver update itself won't erase your devices, but they may disconnect during the update process. After updating, your devices should reconnect automatically. If they don't, unpair and re-pair them manually. This also clears any connection problems that may have existed with the old driver.
Can I update my Bluetooth driver if I don't know the manufacturer?
Yes. Open Device Manager on Windows, expand Bluetooth, right-click your device, select Properties, and go to the Details tab. In the "Property" dropdown, select "Hardware IDs." The ID string will contain the manufacturer code. Search that code online to identify the manufacturer, then visit their support page to read the driver.
What if Windows says my Bluetooth driver is already up to date but my Bluetooth still isn't working?
The driver being current doesn't may provide the connection will work—the problem might be interference, a conflict with another device, or a hardware issue. Try unpairing all devices, restarting your computer, and re-pairing one device at a time. If one device works but others don't, the issue is likely with those specific devices rather than the driver.
Do I need to update my Bluetooth driver if everything is working fine?
No. If your Bluetooth devices connect reliably and stay connected, there's no reason to update. Driver updates are most useful when you're experiencing problems or when you're adding new Bluetooth devices that your current driver doesn't support well.
