The Rogue Connection
Windows 11 is designed to be as seamless as possible when it comes to networking. Whenever you manually connect to a new Wi-Fi network—whether it is at a coffee shop, an airport, or a hotel—Windows saves that network profile and, by default, will automatically attempt to reconnect to it whenever it is in range. While convenient for your home network, this behavior is a massive security risk in public spaces. Your laptop might silently connect to a poorly secured open network or a malicious “evil twin” hotspot without your knowledge, exposing your background internet traffic to interception while you work offline.
Revoking the Auto-Connect Privilege
To ensure your laptop only connects to networks when you explicitly tell it to, you must disable the automatic reconnection feature for specific Wi-Fi profiles.
Press the Windows Key and click the gear icon to launch the Settings app. In the left-hand navigation pane, select Network & internet. In the main window, click on Wi-Fi. Next, click on Manage known networks. You will see a list of every wireless network your computer has ever connected to. Find the specific network you want to modify (e.g., “Starbucks WiFi”) and click on it to open its properties page. Near the top of this page, you will see a checkbox labelled Connect automatically when in range. Uncheck this box. Windows will retain the password for the network in case you want to use it later, but it will absolutely never join that specific network again unless you manually click “Connect” from the system tray.
