   My guess is that your router's DHCP server originally gave your Android   
   device the dynamic IP number 192.168.1.15  (not 192.158.1.15 - that's a   
   publicly routable IP number) and still has it associated with that   
   device because it hasn't run out of unused IP numbers for allocating to   
   other devices on your LAN.  That could happen easily if for example you   
   have six devices that connect to your LAN but the router is set to use a   
   range of 100 dynamic IP numbers.  So when your Android device asks the   
   router 'can I be 192.168.1.15' then the router says 'OK'.   
      
   Dynamic IPs don't /have/ to change each time you disconnect and   
   reconnect.   
      
   You may be able to set the router to use a static IP for the Android   
   device and DHCP for everything else, if you want to be sure.
