I can't get my D-link DNS-321 box to stay networked

Can someone please help me with this? I've tried to figure it out on my own and I'm just not that great with networking challenges.

I think the problem has something to do with the IP address and how it's currently set up through my router. I just can't nail down how to fix it.

I have a physical network connection to my desktop from my router. The same for the DNS box.

Any help would be GREATLY appreciated as one of my main HD's is failing and I can't get anything backed up.

Thanks in advance!

Just updated to Windows 10 but the problem has existed for months prior while running Windows 7 Pro 64.
