Firmware archive labelled Maxnet GAW5.6U2B-5, revision 1.0, packed as a 3.78 MB RAR file. The name gives no detail about chip type, version or tested status, so open the archive and inspect its contents before use. Files of this kind are usually written to the board's SPI flash with a programmer to recover a unit that fails to start after a corrupted update. Compare the board marking and revision on the PCB with the name. Back up the existing chip contents, and check the image size matches the flash capacity.
