Dear all, 

In 2016 I had the issue with my Zyxel NAS 520, that only one of the two LAN ports worked.
I sent the devise for repair and on return the statement from Zyxel was, that a firmware update solved the issue. The device never showed this issue again.  A week ago I sold the NAS 520 and the buyer told me exactly the same error I had two years ago. Unfortunately the firmware is the latest one already... .

Do you have any ideas, on this? Maybe flash the same firmware again?

Thanks and best regards,
Nico.

    When you connected Ethernet cable to NAS520's two LAN ports, does both LAN ports light?
    It looks like HW problem ...
