Hi sitges46,
if you Press and hold Start Copy Black (#5) and Cancel (#2) for a few seconds. The Network configuration page should print and it will list the wireless direct password. There will be an ip address on this page, that should take you to the Embedded Web Server.
Sometimes there might be a proceed button that needs to be clicked on to proceed. Also, have you tried using other web browsers? Such as: Firefox, Or Google Chrome?
Hope this is helpful!
