88keyz, I can DEFINITELY confirm this. I just bought my router, upgraded it to 2.03NA, just only to find out that IPV6 works on wired, and not wireless. I was able to duplicate the problem. I downgraded to 2.01NA, and the problem went away. Now all of my computers, both wired and wireless, connects fine using IPV6. I am using a native IPV6 ISP also. I believe this can be expected of any Chinese products this day and age, the router is a good design, but poor quality control as usual that comes out of China.
D-Link needs to get serious or they will start to lose business if they can't fully test their firmware code for bugs before it is pushed out the door of the factory. Shame on you, D-Link! Get a better QC team!
