   If you did it correctly, you assigned a static IP address   
   _outside_ the so-called DHCP range.   
   Any DHCP server, like in your router is set up to hand out   
   addresses in a specific range. Example:   
      
   network 192.168.1.0   
   netmask 255.255.255.0   
   gateway 192.168.1.1  (the address of the router on the LAN)   
   DHCP range 192.168.1.16 - 192.168.1.63   
      
   Now, if you decide to assign static addresses to any device, those   
   addresses have to be outside the DHCP range.   
      
   192.168.1.0   invalid, it is the address of the network as a whole   
   192.168.1.1   invalid, used by the router   
   192.168.1.2   valid, outside DHCP range   
   192.168.1.25  invalid, in the DHCP range   
   192.168.1.102 valid, outside DHCP range   
   192.168.1.255 invalid, broadcast address for this network

   You probably mean 192.168.1.15 .
