The best thing to do is head over to the D-Link website and find your router (see below). When you reach the product page, click the Firmware link on the right. Scroll down the firmware list and find the latest version of the firmware.Make sure that it is newer than the one you are currently using (Step 2/A above). When you see the prompt about backing up your configuration file, click OK if you’ve backed up the file to continue. Click OK to confirm that you chose the correct firmware file.
