Unable to upgrade firmware on WX3401-B0

syrou Posts: 1

I am trying to update my current device firmware V5.17(ABVE.1)E0 to the latest available version 5.17(ABVE.2.1)C0 but contrary to what I can read in the user manual of the device, I cannot find the Maintenance > Firmware Upgrade menu item in my web UI (I am connecting from the wireless interface). I am concerned that I am not running the latest available firmware version so the router is vulnerable to several CVEs shared in this Zyxel Community. What can I do to be able to upgrade my firmware?

    Hi, I have the same problem. Bought two WX3401-B0 second hand.

    I need to unlock the Firmware upgrade menu, please provide steps on how to do that.

    Thank you.
