OK. First, that dg836gt_1_02_09.img file does not seem to be a firmware file. You need to get a .zip file or a .bin file to upgrade the firmware. Check Netgear's website for the current firmware. If it is a .zip file, then you need to extract the .bin file from the .zip file with winzip software. Then, log into your router with Internet Explorer by typing it the routers IP address in the address bar like this http://xxx.xxx.xxx.xxx. Enter user name and password. Look for a tab that states software update. Browse for the .bin file you downloaded or extracted from the .zip and click update.
