Well, I am new to the forums. I own a DIR-615 H/W Ver.: C1 and F/W Ver.:3.01. I havent updated the firmware since I bought it, shame on me. I downloaded the 3.12NA firmware from http://www.dlink.com/products/?tab=3&pid=DIR-615&rev=DIR-615_revC. It is a zipped folder with a text file and BIN file. I cant use UltraISO or do anything with this image. I don't know where to go from here. If I could get some assistance on getting my firmware updated I would much appreciate it.
