The basic router functions are fairly easy and solid. However, the VPN section is tough. I spent hours working with D-Link Business support trying to figure it out. It finally came down to using IKEv2 in the IPsec protocol setup. The Windows 7 VPN client is IKEv2, but isn't mentioned anywhere in Windows. Then magically all the other settings we were collectively beating our heads about worked! There are continuing issues with in coming connections from some remote locations, but others work perfectly. I believe it has to do with issues at those locations. Working on it. The only other issue is every time you want to enter the router you get a certificate warning in IE 11. You just continue, but it is a pain to deal with especially for something that should have been fixed long ago. We were using a D-Link DIR-655 before, so I reworked it into a wireless access point only, and that allowed us to purchase the wired only DSR-250 at about $60 less than the wireless version.
Excellent device. Easy to use. Simple USB plug-in. Was able to recover data from my system disk, which I had to replace because some blocks corrupted, and the system couldn't be recovered. New disk, reinstalled system, back up and running, but without my old data. This Docking Station let me recover it all. Watch out for other interfaces which don't work on this kind of disk (Dell Inspiron internal HDD). You can use this, with a spare HDD, as an external drive.
I have my TV mounted above my fireplace, and didn't want wires from my cable box and other components sticking out all over the place (and didn't feel like investing in a mantle to hold them!). These work perfectly. Granted, the components are only about 6 feet away, but the picture is crystal clear in HD. The only thing I'm struggling with is the IR so that the remote signal carries to the components when my media cabinet is closed, but it's not the end of the world. It seems a bit finicky, but I'll either figure it out, or keep the door open when I'm lounging.
