Hello. I have a DI-604 router that is not working anymore. I reseted it and then when I tried to log in the software by a navigator( internet explorer, firefox, etc), the window where you put the user and password doesn't even appear. That's weird. It seems as the router does not respond anymore. The power and the Lan ports lights were well lighted. And I typed the correct router default ip adress: 192.168.0.1 It's very weird that the window where you type the user and password of the router doesn't even appear. I really can't figure it out.
