From Ap Mode to network connected mode in cc3200

Hi,

 cc3200 firmware

 So i created ap network and i am able to connect to it. 

  Now i wanted to destroy this ap mode and want to connect to some other network.

 when i  try dissconnect() and then  scannetworks() it returns zero available networks.

how can i do this.

      and is there software RESET for Wi-Fi module

Thanks
