I bought DIR655 just because it offer shareport function. So, I am very keen to see a bug-free firmware on shareport. However, to be fair to the DLINK technical teams, without "reproduce" the problem in their envirnoment, there is no way for a software engineer could fix the bug. From a consumer point of view, totally right, it's DLINK's problem. From a technical or practical point of view, they need to reproduce or got a "problem machine" in order to proceed. You can challenge or complaint to the DLINK company how much resources DLINK company put in this issue but fingerpoint to the technical team seems a bit unfair.
Seems whoever do not have problem before, most (I cannot say all) of the upgrade firmware version will continue works fine (touch wood, I am one of the lucky guy). One the other hand, whoever have problems in previous version, upgrade do not fix this problem. So...the simple conclusion draw from this is the problem is a complex combination of Windows (and installed software etc) with the firmware. It will be good if anyone currently has problem, could do a complete reinstall the windows and sharepoint, and then install the software one by one, until the problem occurred will definitely help the team to reproduce the problem. Of course, is there anyone willing to do this for the sake of the other?

What I saw so far is most of the people just scream out the symphtom and to certain degree, this give only a very little help for the team to locate the bug. It just shooting in the dark. For those user has no problem (just like me), there is nothing we could help...it just work.
