Forgotten password for D-Link DSL G604T wireless router


These are the default settings:

When the login window appears, set the user name to Admin and leave the password box empty. If this doesn't work, you may also try admin for both username and password (all small letters).

If the default doesn't work, you may reset the password by pressing the reset button for 30 seconds. This will bring the router to factory default settings (including all the configurations set on the router).

Hope this helps.
