Bluetooth Connected to Unknown Device: Troubleshooting and Solutions

Bluetooth technology enables wireless communication between devices such as computers, smartphones, and peripherals like keyboards and speakers. Occasionally, users may encounter an issue where a Bluetooth device connected to their computer is displayed as “Unknown Device.” This article delves into the causes of this problem and provides comprehensive solutions to resolve it in Windows 11 and Windows 10 operating systems.

Understanding the “Unknown Device” Issue

The “Unknown Device” error typically occurs when Windows fails to recognize or identify a Bluetooth device connected to the computer. This can be attributed to various factors, including outdated or corrupted Bluetooth drivers, interference issues, or problems with the Bluetooth Support Service.

Troubleshooting and Solutions

To effectively address the “Unknown Device” issue, follow these troubleshooting steps:

1. Preliminary Checks

Ensure that the Bluetooth device’s battery is adequately charged or replace batteries if necessary.
Connect the Bluetooth device to another device to verify its functionality.
Unpair and forget the “Unknown Device,” restart the computer and the Bluetooth device, then reconnect to establish a fresh connection.

2. Run Appropriate Troubleshooters
