are you sure the module freezes completely? Or can you still submit commands on the serial port? If so, you may take a look into this thread: viewtopic.php?f=6&t=1633. I had a problem that Wifi stops working after some time, whilst serial access and the module itself is ok. In the thread you will find a workaround using lua that worked for me.
