I have been trying for hours to get this thing to work...the firmware update 203NA has only allowed MACs with NUMBERS (other than 00) as the first two characters, but still won't allow LETTERS in the first two characters.
I am quickly coming to despise DLINK and their "support" (not only for the router, but also for webcam...ughh).
If this thing isn't fixed soon, I will return or destroy all of my DLINK products.
I've read all the posts related to this and there's nothing new...
