Hi friend
I want to enter into the router that is of D-Link and DI-604 using ip address 192.168.0.1 but can not, Can you help me

Why?

If the page that lets you log in doesn't come up when you go there, try 192.168.1.1, 192.168.15.1, and 192.168.10.1. Those are other popular addresses for routers.

If you actually get to the page and just can't log in, then you need to remember your password. We can't help you get around that.
