Hello,

I recently purchased the TP-Link UB500 Bluetooth 5.3 Nano USB Adapter to connect my AirPods Pro 2 to my desktop PC.

On Windows 10, everything worked perfectly — both audio output and microphone input were stable and reliable.

 

However, after upgrading to Windows 11, the microphone stopped working properly:

• The AirPods connect, but when I speak, only the first 1–2 seconds are transmitted, then audio cuts out.

• From that point on, the Bluetooth connection becomes unstable — it disconnects and reconnects every second, making the microphone completely unusable.

• The sound output also starts to fail intermittently after the mic is activated.

 

I’ve tested this across multiple voice apps and the issue is consistent.

 

What I tried so far:

• Installed the latest U500 driver from support page, and install again: https://www.tp-link.com/en/support/download/ub500 .

• Updated all Windows 11 drivers.

• Disabled Bluetooth power saving options.

• Set AirPods as the default audio and input device.

• Tried using scripts to keep the mic “locked” via software.

• Uninstall the TP-Link driver and reinstall it again using the device manager.

• Un-Paired the AirPods and re-paired them again.

• Reboot system.
• Swtich USB port.

 

Still, the issue persists.
This seems to be a driver-level problem specific to Windows 11.

 

Please advise:

• Is there a driver update planned for full Windows 11 support?

• Is there a known workaround to stabilize microphone input via UB500?

 

Thank you.
Sara
