Resetting your router doesn't mean it wasn't your internet causing the problem, I know my net was bad along with the game lag, and everyone in game I asked that bothered to actually test it had issues with their net as well as the game, for once I can say it probably wasn't Square.

Most people having issues appeared to be on Comcast, though not all, which probably means congestion at a hub Comcast uses that some others go through depending on where they live.
