The following table describes the fields in this screen.
17.6 Firmware Upgrade
Find firmware at www.zyxel.com in a file that (usually) uses the system model name with
a.bin extension, for example, "Prestige.bin". The upload process uses HTTP (Hypertext
Transfer Protocol) and may take up to two minutes. After a successful upload, the system will
reboot. See
Chapter 31 on page 276 for upgrading firmware using FTP/TFTP commands.
Only use firmware for your device’s specific model. Refer to the label on the bottom of your
device.
Click Firmware to open the following screen. Follow the instructions in this screen to upload
firmware to your Prestige.
