d-link wireless router manual dir 615

I can not install my wireless router Dlink DIR-615?

I recently bought D-Link Wireless N Router DIR-615 and I had to make sure everything is properly connected. But I have 1 problem, when I start to install the router, I'm stuck at the part where you put username: admin and password: leave blank, as in the manual, and I did. But I can not install and "incorrect password … etc" still appear. I am very confused, please help

1) Do not install a router, just connect to it. The only software you must use it in your browser. The CD that comes with the router have the manual on it – that's all you need use. 2) Press the reset button on the back. Keep it pressed in. Look at the lights. When you change (about 15 seconds), release the button. Now try connect.
