If Bluetooth is missing or not working in Windows 11, the safest places to get a driver are Windows Update and the support site for your PC or Bluetooth adapter manufacturer. Avoid generic driver-download websites.
1. Check Windows Update First
- Open Settings.
- Select Windows Update.
- Select Check for updates.
- Install relevant updates and restart the PC if requested.
- Check Advanced options > Optional updates for available driver updates. Microsoft notes that optional driver updates are not installed automatically.
2. Get the Driver from the Manufacturer
If Windows Update does not solve the problem, identify the PC model or Bluetooth adapter model and visit its manufacturer’s official support site. Download the Bluetooth driver intended for your exact model and Windows version.
3. Update the Driver in Device Manager
- Right-click Start and open Device Manager.
- Expand Bluetooth.
- Right-click the Bluetooth adapter and choose Update driver.
- Choose the appropriate search or local-driver option and follow the prompts.
If Bluetooth Is Missing from Device Manager
Check Windows Update, restart the PC, and look under Other devices for unidentified hardware. On a desktop with an add-in Bluetooth adapter, confirm that the adapter is connected correctly. The PC manufacturer’s support tools may also identify missing chipset or wireless packages.
Avoid Generic Driver Sites
Third-party driver collections can provide the wrong or modified package. Prefer Microsoft Update or the hardware manufacturer’s official support channel.
Summary
Start with Windows Update, then use the PC or Bluetooth-adapter manufacturer’s official driver if needed. Device Manager is useful for installing or updating a known driver, but random driver-download sites are unnecessary and can create security or compatibility problems.
