Your the only one thats seems to be the one having issue with your routers Sir. We don't see "hordes" of other users with problems regarding what you inaccurately claim to be a design problem with D-Link routers. Many issues seen here in the forums are a configuration or environment problem which most of the time can be resolved with help and information given by my "copy and paste" information. It's helped the "hordes" of users with problems with there routers. We are here in the forums to help users with there problems and questions and to troubleshoot problems as far as we can to either resolve the problem, then if we can't, then refer users to official phone support with D-Link directly to continue to resolve the issue if the problem is beyond forum help. It's seem which this maybe the case in your situation since you seem unwilling to let us help you out nor give feedback to the questions presented.
We are volunteer help for DLink and here to help out with set up and problems that are posted by users here in the forums. If we can not resolve those issues here or if there are problems with anything beyond our capabilities here in the forums, we ask the users please contact phone D-Link directly for continued help and information. Problems with HW/FW and documentation fall under this reasoning as we do not have the ability to effect any changes. As for D-Link support, if they don't know what customers needs as desires are then it's kind of hard for them to make improvements to there products with out someone helping them out and telling them. Yes, of course please feel free to post and talk about it here, however there is little or no review by any official D-Link support or engineering personnel here in the forums. It's the users responsibility to help notify D-Link support of un-resolved problems and concerns they have, that we can't fix here in the forums.
I recommend that you phone contact your regional D-Link support office and ask for help and information regarding this. We find that phone contact has better immediate results over using email.
This thread is now closed. If you want to continue to let us help you in a more professional manor, then we an do that as well.
Good Luck.
