bluetooth-adapter-diagnostic

The bluetooth-adapter-diagnostic tag covers troubleshooting issues where a Bluetooth adapter is detected in Windows Device Manager but connected peripherals, such as keyboards, fail to function. Common themes include devices showing as paired and connected in Bluetooth settings yet remaining inert, multiple phantom device entries appearing after repeated connection attempts, and the peripheral not appearing in the dedicated device list (e.g., Keyboards) despite being visible under Bluetooth adapters. Users often check driver updates via tools like Auslogics or Device Manager, verify Windows updates are current, and compare behavior across operating systems (e.g., iOS vs. Windows) to isolate the problem. The tag focuses on adapter-level diagnostics rather than general Bluetooth pairing or hardware faults.
