Firmware package of 1.30 MB for the P-660HW-T1 hardware version 2, a wireless ADSL router of the Zyxel Prestige series. No firmware build or release date is given in the name, so inspect the archive contents first. Technicians use such files to reinstall firmware on routers after a failed upgrade, usually through the web page or the bootloader recovery console. Check that the unit label shows v2, because v3 hardware needs different firmware, and save the current image and configuration before writing anything.
