Ok, this is what I got: (I want to get into the ROUTER web interface, 10.1.1.5 opens my MODEM interface)

BTW, NONE of 192.168.0.1, 192.168.10.1, or 192.168.1.1 work.

The modem is connected to this computer, the router connected to that, the router gives signals to a laptop and to my 360's wireless connection, if that's of any help.
