1. What is ZyNOS? 

ZyNOS is ZyXEL's proprietary Network Operating System. It is the platform on all Prestige routers that delivers network services and applications. It is designed in a modular fashion so it is easy for developers to add new features. New ZyNOS software upgrades can be easily downloaded from our FTP sites as they become available.
 
2. How do I update the firmware and configuration file?

You can upload the firmware and configuration file by using the firmware upgrade tool which is included in the firmware package.

3. What should I do if I forget the system password? 

In case you forget the system password, you has to erase the current configuration and restore factory defaults by using the Reset button.
Use the RESET button on the rear panel of Prestige 660 to reset the router. After the router is reset, the LAN IP address and the SMT password will be reset to '192.168.1.1' and '1234'. So now you can reach the router through telnet again.

4. How to use the Reset button?

  1. Turn your Prestige off and then on. Make sure the SYS led is on (not blinking)
  2. Press the RESET button for fice seconds and then release it. If the SYS LED begins to blink, the defaults have been restored and the Prestige restarts.
