I have a DIR-615 router, hardware rev. C1 running firmware v. 3.10, dated 4/17/09. I've been beating my head against the wall trying to get this router to properly forward ports for a bit torrent application, but it not only won't do that, it doesn't want to save DHCP reservations and it doesn't want to recognize my computer on the LAN if I set a static IP address (although it does allow my computer to connect and get an internet connection). From the D-Link website, the description of firmware update 3.12NA looks like it might take care of these problems, but I can't get the router to update. When I log into the router and check for updates, it returns a message saying the latest update is v. 3.11, dated 9/15/09. However, when I attempt to download the update, nothing happens. The D-Link website offers update 3.11NA (4/20/09), 3.12NA (3/8/10), and 3.13NA (9/30/10). Why does the website offer me a different update than the router itself? I downloaded 3.13NA and unzipped the folder, which has a text file and a .bin file; I presume the latter is the update. However, when I browse to this file and attempt to upload it to the router, nothing happens. How the heck do I update this router?
