To add Bluetooth to your PC, plug in a compatible USB Bluetooth adapter, install its driver, then turn on Bluetooth and pair your accessories. Check for built-in Bluetooth first, because you may only need to enable it. These steps use Windows 11 menus.
The short version
- Check first: Your PC may already have Bluetooth hardware that needs enabling or a driver update.
- USB setup: Choose an adapter with drivers for your Windows version, processor architecture, and adapter hardware revision.
- Desktop alternative: A compatible PCIe combination card needs a PCIe slot and an internal USB connection for Bluetooth.
- Audio only: A dedicated audio transmitter connects compatible audio equipment but does not add general Bluetooth support.
| Setup option | What you need | Main consideration |
|---|---|---|
| Enable existing Bluetooth | Installed Bluetooth hardware and drivers | Check before buying an adapter |
| USB Bluetooth adapter | Suitable USB port and compatible drivers | Match the adapter hardware revision |
| PCIe combination card | Compatible desktop slot and internal USB header | Install Bluetooth and Wi-Fi drivers separately |
| Supported internal module | Compatible connector, antennas, and approved module | Follow the exact computer service manual |
| USB audio transmitter | Compatible USB connection and audio receiver | Provides an audio connection only |
| Analog audio transmitter | Compatible headphone output and transmitter power | USB supplies power in the Avantree setup below |
Check whether your PC already has Bluetooth
Open Start > Settings > Bluetooth & devices and turn on Bluetooth. With functioning hardware and drivers installed, you can move straight to pairing. You can also select the taskbar Network, Sound, or Battery icon to open Quick Settings, then select Bluetooth. Pressing Windows + A opens the same panel; the shortcut does not toggle Bluetooth itself.
A missing toggle can also indicate a problem with installed Bluetooth hardware or its driver. Open Device Manager and expand Bluetooth to look for an adapter. If it is disabled, right-click it and select Enable device when available, then retry pairing. If the category or adapter is missing, continue with the driver checks below.
If your laptop has a physical Bluetooth switch, move it to its enabled position. In Quick Settings, turn off Airplane mode, then enable Bluetooth.
Choose compatible Bluetooth hardware
A general-purpose USB Bluetooth adapter connects through an external USB port. Before buying, check that its drivers support your Windows version and processor architecture. A Windows 11 compatibility label alone does not establish Windows ARM compatibility, so check the exact model and hardware revision.
For a desktop, a PCIe Wi-Fi and Bluetooth combination card is another option if you have the required slot and internal USB header. An internal wireless module must be supported by your exact computer model, even when another card looks the same size. Choose an audio transmitter only for compatible audio equipment; software settings cannot supply missing Bluetooth hardware.
Install a USB Bluetooth adapter
For the TP-Link UB500, disable existing Bluetooth adapters in Device Manager before inserting the new adapter. Plug the UB500 directly into a USB port. With an internet connection, Windows 11 starts installing its driver automatically.
If automatic installation does not complete the setup, open the official UB500 download page. Under Please choose hardware version:, select the revision printed on your adapter, then open Driver. Download the package matching your operating system and exact regional hardware revision.
Extract the package and run setup.exe or Autorun.exe, as supplied with the driver. Finish installation and restart your PC. Return to Settings > Bluetooth & devices, turn on Bluetooth, and begin pairing.
Pair your headphones or other accessories
Turn on the accessory and put it into its discoverable pairing mode. Open Settings > Bluetooth & devices, or search Windows for Bluetooth and other devices settings and select Open. Turn on Bluetooth, select Add device > Bluetooth, then choose the accessory. If a PIN appears, check that it matches the accessory's displayed PIN, select Connect, and finish with Done.
You can also pair from Quick Settings while the accessory is discoverable. Select Manage Bluetooth devices, choose the accessory under New devices, and complete the device-specific prompts. Select Done to finish.
If the accessory is missing from the results, open Settings > Bluetooth & devices > Devices. Under Device settings > Bluetooth devices discovery, select Advanced. Make sure the accessory is still powered on and discoverable, then try adding it again.
Install a PCIe Bluetooth card in a desktop
A PCIe Wi-Fi and Bluetooth combination card requires a compatible desktop with an available PCIe slot and internal USB header. For the TP-Link Archer TXE75E, check the product specifications for case fit, operating-system support, antenna arrangement, and the included Bluetooth header cable before purchasing. TP-Link lists Windows 11 support for this model.
If you plan to use Bluetooth and already have connected Bluetooth devices, first open Device Manager, expand Bluetooth, and disable every existing Bluetooth adapter, both built-in and third-party. Then shut down and unplug the desktop, and open its case. Connect the supplied Bluetooth USB cable to the card, install the card in an available PCIe x1 slot, and connect the cable to the motherboard's F_USB connector. Fit the appropriate bracket and antennas following the model manual, close the case, and reconnect power.
Obtain the Bluetooth driver from the TP-Link Download Center by locating your adapter, selecting its hardware revision, and choosing the package for your Windows version. Install the Bluetooth driver separately from the Wi-Fi driver, letting one installation finish before starting the other. If Wi-Fi works but Bluetooth does not, check that you completed the Bluetooth cable connection and separate driver installation. Shut down and unplug the desktop before reopening its case.
Replace a supported internal wireless module
An internal wireless-card replacement is specific to your computer model. Use its service manual and approved wireless-module list to confirm the connector, antennas, and supported card. Matching physical dimensions alone is insufficient.
Dell lists RTL8852BE and RTL8852CE Bluetooth 5.3 modules for the Inspiron 16 5640. Replacing its wireless card removes the existing Wi-Fi and Bluetooth hardware from the computer. Follow that model's preparation and removal procedures before installing the supported replacement.
Align the replacement card with the WLAN connector and insert it. Connect the white antenna lead to MAIN and the black lead to AUX, then secure the bracket with the M2x3.5 screw. Reinstall the base cover and complete Dell's post-service procedure. Apply these details only to the Inspiron 16 5640; use your own model's manual for another PC.
Connect audio through a dedicated transmitter
For a Creative BT-W6, connect the transmitter to a USB-C port, using a suitable USB-A adapter if needed. Put your compatible headphones or speaker into pairing mode, then hold the transmitter's multifunction button for two seconds to start pairing. This provides a separate audio connection and does not add general Windows Bluetooth support for mice, keyboards, or file transfer.
An analog transmitter can use a compatible PC headphone output instead. With the Avantree HT41899 Plus 2, supply USB power, move its switch to ON, and connect the PC headphone output to the transmitter's AUX input using the supplied 3.5 mm cable. Select the PC headphone output, play audio, and turn on the included headphones. USB supplies power only in this setup.
Install or update a missing Bluetooth driver
When Windows detects an adapter that does not work correctly, open Device Manager > Bluetooth. Right-click the adapter and select Update driver > Search automatically for drivers. Complete installation and restart your PC. If the computer stops responding, follow the steps to restart a computer that freezes.
For another driver route, open Start > Settings > Windows Update and select Check for updates. For optional drivers, open Advanced options, turn on Receive updates for other Microsoft products, then select Optional updates under Additional options. When an applicable driver is offered, select it, choose Download and install, and restart. If no applicable package appears, obtain the driver from your PC or adapter manufacturer.
For a Dell PC, open Dell's Drivers & Downloads page and identify the computer using its Service Tag or model, or select Browse all products. Obtain the Bluetooth package matching that PC and operating system. For another brand, use that manufacturer's official support page and match the exact PC or adapter.
Run the downloaded driver's executable installer if one is supplied. For an extracted driver package, right-click the adapter in Device Manager, select Update driver, then select Browse my computer for drivers. Select Browse, choose the extracted folder, and select OK > Next > Close.
Fix a connection that still fails
For continuing connection problems, open Microsoft's Bluetooth troubleshooting page and select Run the troubleshooter in Get Help. Follow its diagnostic prompts to repair the existing Bluetooth connection.
Removing an accessory deletes its saved pairing from the PC. For a failed or stale pairing, open Start > Settings > Bluetooth & devices > Devices, select the accessory's More options > Remove device, then select Yes. Put the accessory back into pairing mode and add it again.
Rolling back replaces the current Bluetooth driver with its previous version. If Bluetooth stopped working after an update, open Device Manager > Bluetooth, right-click the adapter, and select Properties > Driver > Roll Back Driver when available. Follow the displayed instructions; if rollback is unavailable, continue with the manufacturer's matching driver or the adapter redetection procedure.
Uninstalling the adapter removes its current device installation from Windows. If installed Bluetooth hardware still malfunctions or its toggle has disappeared, open Device Manager > Bluetooth, right-click the adapter, and select Uninstall device, then Uninstall. Shut down the PC and power it on again. If necessary, open Device Manager and select Action > Scan for hardware changes.
