The Best Way to Block a Wi-Fi Signal

by Steve Gregory

Removing a Wi-Fi network’s profile from your computer will prevent the machine from automatically connecting to the network when it is within range of its Wi-Fi signal. Run Netsh commands using the Command Prompt utility to both find the Wi-Fi profile you need to delete and remove it from your computer. You can delete the profile even if your computer is no longer in range of the Wi-Fi network’s signal.

Press the "Windows-Q" keys to open the Search charm and enter "Command Prompt" in the Search box.

Choose "Command Prompt" from the Results screen to launch the Command Prompt window.

Type "netsh wlan show profiles" -- without quotations -- and press the "Enter" key to display the list of Wi-Fi profiles.

Locate the profile that you need to delete and record the name.

Type "netsh wlan delete profile name= Wi-Fi Profile Name" -- without quotations -- and press "Enter." Replace "Wi-Fi Profile Name" with the wireless network's name that you need to remove.
