what is the model of your router?
usually if your pc gets 192.168.1.64 the router's ip must be 192.168.1.254
this number you will use as the gateway in genesis settings.
you must set the subnet mask too which must be 255.255.255.0
and of course you must set the dns which is the same as gateway.
the 192.168.1.200 is a good ip to set for your amiga IF all the other settings i said are valid.
try and tell us.
