Are you sure?
Do you have this information from Dlink?
I also have a HWA3 version but the loginpage says A2.
The reason that it is A3 was becourse of the firmwareupdate 1.21 for the HNAP0wn fix. I contacted D-Link in the time i had a Dir655. That was a A5 but above the login was A4. I think they did it whit all there routers.
To bad there is no information about if the DIR-855 get an update for IPv6 support.
