I haven't found dealing with D-Link support to be very illuminating or useful.  The one time that I did try to talk to them, they wasted a lot of my time, which I'm not eager to repeat.  However, a certain number of people test their router to see if it is vulnerable using the reaver program.  That's what I was trying to find out, if anyone who reads this forum has done this, and what the results were.
My Linksys E4200 was tested by several people and failed.  As a result, I switched it to tomato open source firmware, and it's doing fine.  As there is no open source firmware for this router, which I use as an AP, I thought I'd ask.  Yes, D-Link will have to fix this if the router turns out to be vulnerable.
