Hi
192.168.1.1 is I/P address of some broadband routers
others use 192.168.0.1 and a variety of other address
If you give make & model some one may give you correct address
If this modem router was supplied by a ISP ask their technical support for help
ISP will give you written list of settings, username & password which have to be entered into router to connect to their broadband service
at cmd prompt on your PC ipconfig /all will give useful info about network configuration of your PC
regards
Mike Barnes
