Server Based indoor positioning using Wi-Fi

The 192.168.0.1 address is the default LAN IP address assigned by the router manufacturer on several router models.  As with any default setting, it should be changed to match ones own internal numbering scheme. Knowing this doesn't help, as the OP has already indicated he can access the router. His problem is he wants to retrieve from the router information that is supplied by the device, i.e. the received signal strength and GPS location. Since the router does not permanently store the actual packets sent by the device, the only way to get it is with a 'sniffer' between the device and the router.
