Wireless adapters may become unstable, disconnected or show the Code 10 error in Device Manager (error message: this device cannot start) if there is a change being made to the device (e.g. running Windows Update).
If wireless adapters ever run into the situations mentioned above, please refer to the following for the troubleshooting steps.
Uninstall the following applications if they had installed on the laptops, since they might cause potential conflicts when installing the drivers.

2. Applications that can automatically search for and install drivers
1. Download and save the drivers for the wireless adapter.
- Intel Wireless: Download the latest version from Intel website
