Hello,
I have a NAS542 and the firmware V5.21 (ABAG.7) installed. Since the firmware was installed, the NAS no longer switches off in the late evening.
This worked perfectly with the previous firmware version.
Where can I download the previous firmware version? (If possible please a direct link).

Thanks and regards ... Stevie

    Hi,
    it works. Downgrade has been finished successful. The NAS is now running V5.21(ABAG.5)C0. Autoshutdown is working now.

    Do anyone know, why ABAG.6 is not available for download?

    Regards ... Stevie

    Imagine an up to date firmware for the NAS542, so people wouldn't have to disconnect it from the internet or directly trash it...
