I can't log on to my router with http://192.168.1.1 or with http://192.168.0.1

   "unable" is not a useful problem description.  It does not say what
you did.  It does not say what happened when you did it.  As usual,
showing actual actions (commands) with their actual results (error
messages, LED indicators, ...) can be more helpful than vague
descriptions or interpretations.

   "my router"? That's one of these?:

> Model: R7000|AC1900 Smart WIFI Router

   To what is it connected?  What's the IP address of the
computer/device where you're running the web browser?

   Visit http://netgear.com/support , put in your model number, and look
for Documentation.  Get the User Manual (at least).  Read.  Look for
"Troubleshoot".

> http://192.168.0.1

   Try "10.0.0.1"?   Or, as the manual says, "routerlogin.net"?
