Hello.I resolved this issue thanks to the user Baltzatu on both the:D-Link official FORUM -> http://forums.dlink.com/index.php?topic=65405.0and the DSM-G600 forum -> http://forum.dsmg600.info/viewtopic.php?id=7525
Now I want to upgrade to the RC5, but I'm reasonably scared...
I wasn't able to find the fixes for the network data corruption of the RC5, are just in the actual firmware?
P.s. I'm pretty sure that I have downloaded the right firmware image the first time (DNS-320 Rev. A1), but the flash went wrong.
