Connection issues (months now).

So, when I first tried FFXIV (like, right when ARR launched), I could connect to the game no problem. I played for a month or so, then went back to my WoW addiction.

Cut to a few weeks ago, I decided to come back to FFXIV, and I couldn't log in. After looking around, I tried a tunneler, and was able to connect while using it. I wasn't happy about it, but that's the way it was.

And now, as of the server move, I can't connect at all, tunneler or no.

I just had Comcast come in and check everything out -- they replaced an amplifier, tightened a couple loose cables, all that. They said everything should be fine. Still no connection.

What is the issue?
