Support for Firmware Version 2.x Concludes on September 10, 2020

To enhance the customer experience, we urge all users to upgrade to Firmware Version 3.x, including those with discontinued products (ZBT-MT300N & ZBT-MT300A). Support for Firmware Version 2.x will end on September 10, 2020. While users of Version 2.x will still access most router services, the following issues may arise:

1. Package installation via the Admin Panel will be disabled, though existing packages remain unaffected.
2. New versions cannot be accessed or downloaded through the Admin Panel. Manual downloads are available [here](#).
3. The DDNS function will be unavailable.
