Hi HI KALAI,
Thanks for reaching out to Microsoft Q&A Forum. I understand that your Bluetooth connection keeps disconnecting automatically on Windows 11.
Please make sure you already tried the Q&A Assist steps. In addition, please try the following.
Before that, I’d like to narrow this down a bit:
1, Does the disconnection happen with all Bluetooth devices or only one specific device (for example, headset or mouse)?
2, Does the issue occur mostly after the PC wakes from sleep or when switching between battery and charging?
In the meantime, you can try these steps:
1, Turn off Fast Startup
- Open Control Panel
- Select Power Options
- Click Choose what the power buttons do
- Click Change settings that are currently unavailable
- Uncheck Turn on fast startup
- Restart the PC
2, Restart Bluetooth-related services
- Press Windows key + R, type
services.msc, and press Enter - Restart Bluetooth Support Service
- Restart Bluetooth Audio Gateway Service (if available)
3, Disable USB selective suspend
- Open Control Panel
- Select Power Options
- Click Change plan settings next to the active plan
- Click Change advanced power settings
- Expand USB settings
- Set USB selective suspend setting to Disabled
4, Check Windows Update for optional driver updates
- Open Settings
- Go to Windows Update
- Select Advanced options
- Open Optional updates
- Install any available Bluetooth or chipset-related updates
5, Temporarily disable Bluetooth power saving from advanced adapter settings
- Open Device Manager
- Expand Network adapters
- Open your wireless adapter Properties
- Check the Advanced tab and disable any power-saving or sleep-related options if present
6, Test with a clean restart environment
- Press Windows key + R, type
msconfig, and press Enter - Select Selective startup and uncheck Load startup items
- Restart the PC and test Bluetooth behavior
