Hello @fime50 ,

Welcome to our community.

Here are some additional steps that may help prevent the Bluetooth from occasionally deactivating:

1. Verify Power Management Settings in Device Manager:
Open Device Manager, locate your Bluetooth adapter, double-click it, and go to the Power Management tab. Make sure "Allow the computer to turn off this device to save power" is unchecked.

2. Disable Built-in Bluetooth (if applicable):
If your computer has a built-in Bluetooth adapter, disable it in Device Manager to avoid potential conflicts with your TP-Link adapter.

3. Check F_USB Port Connection (for PCIe adapters with Bluetooth):
If you're using a PCIe adapter with a Bluetooth USB cable connection to the motherboard, try connecting to a different F_USB port.

4. Update Motherboard BIOS:
Since you recently changed the wireless protocol settings, verify your motherboard's model number and visit its official website to check if there's a BIOS update available.

5. Minimize Interference:
Keep the adapter away from interference sources such as microwaves or other wireless devices that might cause signal disruption.
