    Hi guys,

    Really hope you can help. Here we go:

    Main problem: I can't connect to my DS212j. My router just gave up, and I have to transfer 300GB of stuff from my iMac to my DS212j within this weekend :(.

    I've read something about it being possible to connect the DS212j directly to my iMac via the ethernet port, but I cant make it work. This is what I've tried:

    - I can't remember my DS212j ip (but I think it was set for - and since I cant connect to the DS212j, I can't check).
    - iMac has static ip, subnet
    - Wifi is also enabled on my iMac (using my Android phone as modem right now). I've tried to turn off wifi to see, if that made a diffence, but no :(.
    - I've tried to make Synology Assistant to search for the DS212j, but doesn't show up.

    What is it, I'm doing wrong? If someone could put me in the right direction, I'll send massive amounts of sunshine in yours!

    If you can't get it working, toto Walmart buy a router. Then return it after you're done.

    If you don't have a switch and are having to connect them directly to each other, you may need a crossover cable instead of the regular pinout. I would ask you neighbors to borrow a small switch.

    Did you turn on the Mac's Internet Connection Sharing? For your setup, it'd be Share Wifi/Airport TO Ethernet. After this, did you try going to http://NAS_Name.local?

    That should work regardless of what net address it's trying pull.

    You don't need cross over cable the port auto sets its self.

    By the way, this worked. Love my DS212! No one responded to this guy and i just tried it and all is well :) Thought the next guy like me reading this should know! I just saw it appear in the shared section of my sidebar in all my folders, though, i couldn't get the http://NAS_Name.local to work. And how do i get to log into the DSM of the NAS now?

    To connect your NAS to Mac directly on OS X 10.10 or later, follow these steps:

    1. Launch [Sharing] in [System Preferences].
    2. Set [Share your connection from] to [Wi-Fi] which is the configuration name for 802.11n device.
    3. Set [To computer using] to [Ethernet] which is for Gigabit Ethernet device.
    4. Click on [Internet Sharing] to enable.

    Then use vi to look for “OFFER sent + NAS host name” in /var/log/system.log to get the IP of NAS.

    For QNAP devices, launch Qfinder before turning on NAS. It will show up in the list with IP address. If you turn on NAS before launching Qfinder , it won’t be able to find it.

    For Synology devices, Synology Assistant won’t help.

    Detail explain in Connect NAS to your Mac Directly with Ethernet.

    Wish it helps!

    Best regards,
