Probably because the your LAN is 192.168.1.0! Your router address is 192.168.1.1, since your address is 161.63.x.x it's not in the same subnet. Not routeable, even if you put 192.168.2.x, this is a private address, still won't work because your router is in the 192.168.1.0 network. Consider changing it's address to match the current network being used.
