The backflow warnings are designed to alert you to a possible problem with the wireless network, and are triggered when a device connects to a Wi-Fi network without a passcode.
If you have a mobile phone with a Wi.
Fi connection, the warning should go away, even if you don’t have a password.
But many devices have the capability to send you a backflow message, which you should ignore.
If a device is able to send backflow messages, you can block them and get back on track.
