After reinstalling Windows 7 32-bit on an HP 2000-2106TU Notebook PC, Bluetooth may not work correctly or Bluetooth Peripheral Device may appear as an unknown device in Device Manager.
The issue can occur when the required Bluetooth driver is missing after reinstalling the operating system.
Cause
Bluetooth drivers are specific to the wireless/Bluetooth adapter installed in the notebook. Installing an incorrect Bluetooth driver may not resolve the issue.
For the HP 2000-2106TU Notebook PC
The original post identifies the notebook as HP 2000-2106TU Notebook PC, product number B6U41PA, with a missing Bluetooth Peripheral Device driver.
Troubleshooting steps
1: Confirm the notebook model
Verify that the notebook is an HP 2000-2106TU Notebook PC.
Confirm the product number if possible.
If you have a different HP notebook, do not install this driver without first confirming that the Bluetooth/Wi-Fi adapter is compatible.
2: Download the Bluetooth driver
Download the Qualcomm Atheros QCA9000 Series Bluetooth 4.0+HS Driver for Windows 7 32-bit from the HP
3: Install the driver
Download the driver file.
Locate the downloaded .exe file.
Double-click the file to start the installation.
Follow the on-screen instructions.
Restart the notebook after the installation completes.
4: Check Device Manager
After restarting:
Open Control Panel.
Select Device Manager.
Expand Bluetooth or check Other devices.
Look for the Bluetooth adapter or Bluetooth Peripheral Device.
Verify that there is no yellow exclamation mark beside the Bluetooth device.
If the Bluetooth device is recognized without an error, test Bluetooth by pairing a Bluetooth-enabled device.
If Bluetooth Peripheral Device Still Appears
If the main Bluetooth driver installs but Bluetooth Peripheral Device remains unidentified:
Open Device Manager.
Right-click the affected Bluetooth Peripheral Device.
Select Properties.
Review the device details and hardware ID.
Confirm that the hardware ID corresponds to the Bluetooth device installed in the notebook.
Reinstall the appropriate Bluetooth driver if necessary.
Restart Windows and check Device Manager again.
Important Windows 7 Consideration
Windows 7 is an obsolete operating system, and some older Microsoft software or supporting components referenced in historical Bluetooth installation procedures are no longer supported.
Therefore, if the Bluetooth driver installs successfully but a Bluetooth peripheral remains unresolved, the issue may involve missing legacy Windows components rather than the primary Bluetooth driver itself.
Troubleshooting Checklist
If Bluetooth is still not working:
Verify the exact HP notebook model and product number.
Confirm that Windows is 32-bit.
Confirm that the Bluetooth/Wi-Fi adapter is compatible with the driver.
Install the Qualcomm Atheros QCA9000 Series Bluetooth 4.0+HS Driver.
Restart the notebook after installation.
Check Device Manager for error codes or yellow exclamation marks.
Check the Bluetooth hardware ID if the device remains unidentified.
Remove and reinstall the Bluetooth driver if necessary.
