The D-link's default login details are user name "admin", password is blank, and type the captcha from the image.
Once you get logged into the router look for the wireless setting on the menu on the left.
Once their you can reset your password to your SSID(which is your wireless networks name)
If you cannot log into the router you can reset the router back to its factory defaults allowing you to log in with the info above.
To do this find the small reset button on the back or side of the router, it is a small pin hole.
While the router is plugged in use a paper clip or a pen to press and hold the reset button on the router for 30 seconds.
This will restore the factory settings and you will then be able to log in with the info I provided above.
Please be aware if you reset the router to factory defaults the name of your wireless network will change back to it's default name, most likely dlink.
