To update the firmware, there is a need to:

1. Download the actual firmware from the official website of a company (a page with a description of a device, the section «Documentation and Files»);
2. Go to the page «FIRMWARE» of a device web interface. Using this page, you can update the firmware of a device without using specific applications. To do this, you will need a browser that supports HTML 5 API. Google Chrome or Internet Explorer older than 9th version are recommended;
   
3. Drop a firmware file to the indicated area of the page;
