I have a d-link di-624 . I want to login to my router setup utility so I can setup some application gateways, (ie. waste). Now, I go there, but it is asking for a password. I don't remember putting one in, (my dad did it actually, and he says he didn't), and it is asking for one. I assumed it is blank, so I press enter, but it still doesn't work. Help would be awesome! Thanks!
