Firmware archive of 3.20 MB for the NBG-419N, a Zyxel wireless N router. The name has no version number or hardware revision, so inspect the archive and its file names before use. Repair work with such packages involves reinstalling firmware on units with a failed upgrade, through the web interface or a recovery mode in the bootloader. The NBG-419N was produced in more than one hardware version, so confirm the label matches the image, and back up the existing flash before writing a new one.
