    I suggest you try reset to default settings via the hardware button or contact your ISP for assistance.

    Hello @Sliman

    You could try the information at

    Or if you have a contract with WindTre then ask them for the original firmware.

    I don't know if the Zyxel VMG8828-B50B is end of life or not.

    Kind regards,


  • This article is the one from which I downloaded the new update, and I already upgraded the device, and after upgrading the device there were many problems such as the inability to control the device on 5GHz Wi-Fi? I want to restore the old system. How can I recover the main interface of the device and the system that was in it? I want to erase this new system and restore the old system that was with the device.
