As others have reported, after a few days to a few weeks the switch simply stops forwarding packets, requiring a reboot. I have now replaced it with TRENDnet TEG-30102WS. So far no problems. It's MUCH more expensive, but I need something that doesn't crash randomly. I opened a ticket with QNAP support and although they responded to the query, they couldn't find anyone from tech support who could even speak to me about the issue. . Hence the 1 star rating for technical support.
