It was pretty easy. I just followed the directions and it went without a hitch. Again, though, the only thing I would recommend against is the instructions it gives in the end on how to sign up and download the mydlink program, which in my opinion is a waste of time. It also lists in the booklet that if there are any questions or problems, they should be directed to D-Link, but this is incorrect, and they may have changed it for the newer booklet. The place to get help for these routers is Hughesnet, not D-Link.
The thing I had to tweak was changing the security settings to "WPA2 Only" and AES (it may have already been on AES, I can't remember for sure), but I did this at a later time by following advice one of you champs had given to someone else. I can't remember if you can change it to "WPA2 Only" during the setup wizard, but if not, it's easily done afterward. And the default setting is "WPA / WPA2", so it's not like it wouldn't be secure from the beginning, anyway.
