I have a dl4100 and have never established an admin password and all folders are public. It was been working great for a year and now, coincident with a firmware update I can’t access the dashboard. The user is admin and in the password field it says no password created in gray letters. In the past I just hit the login button and the dashboard came up. Now it tells me “The user name or password you entered is incorrect. Visit here for assistance.”
I reset the NAS to factory defaults with the button on the back. I power cycled the device. I restarted it. Still the same problem.
I have to assume that it must be something in the firmware update. Is anyone out there having the same problem? Very frustrating.
