Your connection to the wireless network is turned off

Hi there,
This morning I got this error when I tried to connect to my home wireless network with my phone. It says that no connection was found and I have verified everything, the Internet connection is working, wireless is activated and I made a new connection on my phone. Does anyone have any idea about this error ? What could be the error ?
Thank you !
