Windows 11 remembers networks you have connected to previously and will automatically reconnect if they are in range. This is a security risk if the network is public or compromised.
How to Stop Automatic Connections
- Click the Wi-Fi icon in the taskbar, then click the arrow next to the Wi-Fi symbol.
- Right-click the network you want to modify and select Properties.
- Under the “Connect automatically when in range” setting, toggle the switch to Off.
