DON'T UPGRADE TO THE 1.12 FIRMWARE!!!
I upgraded to 1.12 from 1.11 Beta. I saved my very intricate configuration before upgrading to 1.12. The upgrade went fine and wiped out my config. No problem, it warned me prior to the upgrade and I have my backup to go back to. I even have a couple copies of it. Well guess what, the configuration load FAILED!!!
Restore Invalid
The restored configuration file is not correct. You may have restored a file that is not intended for this device,

Try the restore again with valid restore configuration file.

So I tried to reload the 1.11 Beta firmware. It FAILED TOO!!!
Upload Failed
The uploaded firmware file may not be correct. You may have uploaded a file that is not intended for this device, or the uploaded file may be corrupted.
If the uploaded file is correct, it is possible that the device may be too busy to properly receive it right now.
In this case, please try the upload again. It is also possible that you are logged in as a 'user' instead of an
'admin' - only administrators can upload new firmware.
The Gateway will not be reprogrammed.
Needless to say, I got what I deserved. I thought they had actually fixed the issues since 1.11 Beta worked well for me. Now I can't even go back to what I had working without a lot of tweaking from the default configuration.
I'm so mad I want to throw my 4500 and every other D-Link product out the window and go back to using my Linksys equipment.
