A WiFi driver is low-level software that allows Windows 10 to communicate with your wireless network adapter (hardware). It translates OS commands (e.g., “connect to SSID ‘HomeNetwork’”) into instructions the specific adapter chipset (Intel, Realtek, Broadcom, Qualcomm/Atheros, MediaTek) understands.
Before updating, you need to know exactly which Wi-Fi adapter your system uses. You can find this information in the : Find the WiFi driver used by a computer - IDrive® Mirror windows 10 wifi driver
