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.
