Bluetooth is not working

[Kunal_ranjan]

Dear Support Team,

I am writing to request your assistance with a critical issue affecting my Bluetooth functionality.

Background:

• My computer was running Windows 8.1 for an extended period.
• Last year, I successfully updated to Windows 10.
• All functionalities, including Bluetooth, were operating smoothly until recently.

Problem:

• Approximately 3-4 months ago, my Bluetooth connectivity abruptly ceased to function.
• I have diligently attempted all available solutions to troubleshoot the issue, but unfortunately, none have yielded positive results.

Diagnostic Efforts:

• I followed these steps:
  • Opened Device Manager
  • Navigated to View > Show Hidden Devices
  • Expanded "Bluetooth Devices"
  • Right-clicked "Ralink Bluetooth PCIe Adapter"
  • Selected "Properties"
• The following error message was displayed:
  • "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)"
  • Additionally, the message "Windows cannot verify the digital signature for this file. The signing certificate for this file has been revoked."

Impact:

The inoperability of my Bluetooth connectivity significantly hinders my productivity and workflow.

Request:

I urgently request your assistance in resolving this issue and restoring my Bluetooth functionality. I would be grateful if you could guide troubleshooting the driver issue and verifying the digital signature.

Thank you for your time and attention to this matter. I look forward to your prompt assistance.

Sincerely,

Dr Kunal Ranjan

Thanks and warm regards
