Firmware archive for the Goldweb GD-W809N, a wireless networking device, stored as a 1.59 MB RAR file. No hardware revision or firmware version is given in the name, so the contents should be inspected before flashing. Images like this are mainly used to revive a unit with corrupted firmware, often by writing the SPI flash chip directly with a programmer such as a CH341A. Read and keep a backup of the existing chip first, and make sure the image size matches the flash capacity soldered on the board.
