Troubleshooting Wi-Fi and Bluetooth Connectivity Issues After Upgrading to Windows 11 on a Dual-Bboot System

Upgrading to a new operating system can sometimes lead to unexpected hardware recognition issues, especially when juggling multiple OS environments like Ubuntu and Windows. If you’ve recently installed Windows 11 on your device and are experiencing missing Wi-Fi and Bluetooth functionalities, you’re not alone. Many users have encountered similar problems post-upgrade, often due to driver-related complications.

Common Symptoms

Wi-Fi and Bluetooth icons are missing from the system tray.
Network adapters are not visible in Device Manager.
Attempted driver installations from the manufacturer do not resolve the issue.
Persistent hardware recognition issues despite rebooting.

Troubleshooting Steps

Here’s a comprehensive approach to resolve missing Wi-Fi and Bluetooth adapters after upgrading to Windows 11:

1. Verify Device Detection in Device Manager

Begin by opening the Device Manager:
– Press Windows + X and select Device Manager.
– Look under Network adapters for your Wi-Fi and Bluetooth devices.
– If they are missing or appear with a yellow warning icon, driver issues are likely.

2. Show Hidden Devices

Sometimes hardware devices are hidden:
– In Device Manager, click on View > Show hidden devices.
– Check if your network adapters appear now.

3. Use Windows Update for Drivers

Navigate to Settings > Update & Security > Windows Update.
Click Check for updates. Windows may find and install generic drivers for your network hardware.

4. Download and Install Manufacturer Drivers

Identify your device model and chipset.
Visit the manufacturer’s website to download the latest Windows 11-compatible drivers.
Install them manually and reboot.

5. Use Compatibility Mode

If drivers are not available specifically for Windows 11:
– Right-click the driver setup file.
– Select Properties > Compatibility tab.
– Check Run this program in compatibility mode for and choose Windows 10 or Windows 8.
– Install the driver and reboot.

6. Update BIOS and Firmware

Occasionally, BIOS updates are necessary for hardware compatibility:
– Visit your device’s manufacturer support page.
– Follow instructions carefully to update BIOS.
