If a user chooses to manually update the firmware of his Dlink router then he has to make sure that before downloading the latest firmware for his router he must know the correct model number and product name of his device. After downloading the firmware choose an appropriate location form where you can easily fetch your firmware to upload it into the web interface of your router. If the download file is in .zip format then don’t forget to extract the file as it gives convenience to users while uploading that file into the
dlinkrouter.local window.
