I am using hp laptop windows 10, and have nighthwak router. It worked properly bu yesterday suddenly it showing error.
---- I Reset router, restart my computer, Plug on/off router but it not connecting.
---- It is showing 'routerlogin.net not responding' error.
---- I enter 192.168.1.1 instead of routerlogin.net but it is showing same error.

I unable to understand, what is the issue. Is it from router side or laptop side.
or may be it is networking issue.

Is anyone there who can help becuase, i can't access internet.
