Wi-Fi is a wireless local area network (WLAN) technology and standard that uses high-frequency radio waves to provide wireless Internet and network connections to your Windows device.
When you connect to a Wi-Fi network for the first time, Windows will automatically add a profile for the Wi-Fi network. The saved profile contains the SSID (network name), security key (password), and security type information used to connect to this specific Wi-Fi network.
This tutorial will show you how to delete a Wi-Fi network profile in Windows 11.
