The more I read the dlink forums, the more I think that some people on this board have no clue about quality control or are in some sort of denial about the quality of the firmware. If a feature exists, and it doesn't work correctly, then its definitely a bug, and it should be fixed. Whether or not the feature was unintentionally added has nothing to do with whether its a bug. It only affects the path to resolution. If its an unintentional feature, then remove it. If its a purposely added feature, then fix it.
