FAQ

Q: When troubleshooting a Bluetooth issue, why is it recommended to reinstall the WLAN driver as well?

A: This is because WLAN and Bluetooth are integrated into the same wireless module. Although they use separate drivers, both functions may be affected by the module’s driver compatibility, initialization, and power management. Reinstalling both drivers helps restore a clean and compatible wireless environment, especially when the issue occurs after Windows Update, Bluetooth disappears from Device Manager, or WLAN and Bluetooth are both unstable.
